Sushi Bar Design, Counters & Chef Workstations

01 — Anatomy of a Professional Sushi Bar

A sushi bar consists of more than its visible preparation counter. The chef's working surface, refrigerated ingredient access, rice station, guest dining surface, supporting storage, and production kitchen all determine how the counter operates.

The most important physical distinction is between final preparation at the counter and the work supporting it.

At the working counter, the chef needs access to the day's neta, prepared sushi rice, cutting surface, knives, nori, garnishes, and finishing tools. Depending on the concept, the counter may also incorporate refrigerated display equipment, undercounter storage, and direct guest service.

Nearby or elsewhere in the restaurant are the functions that keep this station supplied: fish breakdown, bulk refrigerated storage, rice washing and cooking, seasoning, hot-food production, warewashing, and receiving.

A successful counter gives the chef appropriate access to these functions without requiring every piece of equipment to occupy the guest-facing preparation area.

The principal physical areas

Scroll horizontally to read the full table →

These areas need not be arranged in one prescribed sequence. An intimate omakase restaurant may use a visually restrained counter supported by a separate kitchen. A high-volume sushi operation may prioritize distributed preparation stations and convenient access to refrigeration. A hand-roll concept may place direct chef-to-guest handoff at the center of its layout.

The appropriate arrangement follows the work.

For a complete illustrated inventory of specialized equipment and terminology, see Illustrated Sushi Restaurant Equipment, Tools & Supplies Encyclopedia.

02 — Start with the Restaurant's Operating Model

The counter configuration should follow the menu, service format, chef responsibilities, and production requirements.

A traditional full-service sushi bar may combine visible preparation with a larger kitchen producing tempura, cooked dishes, soups, and appetizers. An omakase counter may concentrate the guest's attention on one or two chefs performing most of the final preparation in view. A hand-roll bar requires immediate delivery of completed temaki. A high-volume production counter may have little guest-facing function.

These distinctions affect the location of refrigeration, rice, work surfaces, support stations, seating, and service access.

Establish the requirements before selecting a counter shape

The initial design should resolve:

• Menu composition and where each preparation task takes place.
• Intended service volume and number of simultaneous chef positions.
• Which dishes are handed directly to guests and which pass through servers or other delivery systems.
• Whether the counter is primarily a presentation station, production station, or both.
• The location of major refrigeration, fish preparation, rice production, and hot-food equipment.
• Supporting employee circulation, ingredient replenishment, cleaning, and dish return.
• Guest seating, accessibility, and the intended relationship between chef and diner.
• Existing spatial and utility limitations.

How operating models change the counter

Scroll horizontally to read the full table →

The same geometric layout can serve more than one concept. A U-shaped counter may accommodate a small, chef-focused experience or a multi-chef hand-roll operation. The working arrangements, equipment, and guest interaction can still be very different.

The first design decision is therefore not whether the counter should be straight, curved, or horseshoe-shaped.

It is what the counter must allow the restaurant to do.

For complete equipment requirements by concept, refer to the corresponding Traditional Sushi Bars, Omakase & Edomae, Hand-Roll Restaurants, and other concept resources.

03 — Map the Workflow: From Ingredients to Guest Service

The sushi bar's layout should follow the movement of its ingredients and finished food.

Fish, rice, nori, hot-food components, finished sushi, dishes, and waste take different routes through the restaurant. Their intersections can determine whether a workstation operates smoothly or becomes congested.

Seafood and refrigerated ingredients

Fish may arrive as whole fish, dressed products, or portioned ingredients. Receiving, primary refrigerated storage, breakdown, portioning, and final counter preparation do not necessarily happen in the same area.

The distance between the supporting preparation area and the chef's neta access matters during replenishment. So does the available chilled capacity at the counter.

The guest-facing refrigerated case, where used, should not be expected to perform every refrigerated-storage function in the kitchen.

Sushi rice

Rice moves through washing, cooking, seasoning, staging, and final use.

At a small counter, the chef may work from a wooden rice vessel close to the cutting surface. A larger restaurant may prepare and replenish rice from a dedicated production area.

The location of the cooker or rice mixer does not need to match the location where the chef shapes nigiri. What matters is that production, handling, replenishment, and service are coordinated.

Nori, condiments, and smaller ingredients

Nori must be protected from unwanted moisture while remaining accessible for maki, gunkan, and temaki production. Condiments and finishing ingredients need to be close enough to the task without overtaking the cutting surface.

Frequently used items should occupy predictable working positions. Backup supplies should be accessible without becoming part of the immediate preparation clutter.

Hot-food components

Restaurants serving tempura rolls, cooked seafood, aburi preparations, or other hot components require appropriate transfer between the sushi counter and cooking stations.

A counter located far from the hot kitchen may create avoidable staff travel, awkward handoffs, or conflicting service paths.

The appropriate solution depends on the menu and the work assigned to each employee.

Finished food and serviceware

Food handed directly to the guest follows a different route from food sent through a server, conveyor, takeaway packaging station, or refrigerated retail display.

Hand-roll restaurants provide a particularly clear example. KazuNori organizes its service around handing completed rolls directly to diners soon after assembly, preserving the intended texture of the nori.

In a takeout-focused operation, the finished item instead needs to move efficiently into packaging, labeling, staging, and pickup.

Used plates, utensils, containers, and other service items must also leave the working area without interfering with preparation.

Evaluate the entire shift, not an empty workstation

A plan may look efficient with no employees or equipment in operation. The more revealing test is a busy service period:

• Several chefs working simultaneously.
• Refrigeration doors and drawers being opened.
• Rice and neta replenished.
• Finished dishes handed out.
• Used dishes collected.
• Support employees moving through the counter.
• Equipment cleaned or restocked.

The arrangement must withstand these overlapping activities.

For detailed production-capacity and equipment-sizing considerations, see Sushi Production Workflow, Capacity & Equipment Sizing.

04 — Sushi Counter Layouts: Straight, L-Shaped, U-Shaped, Island & Custom

The major sushi-counter configurations differ in chef access, customer interaction, available working space, circulation, equipment integration, and fabrication.

No particular shape is inherently the most efficient. The appropriate configuration depends on how the restaurant uses it.

Straight and linear counters

A linear counter establishes a continuous relationship between the chef's working position and the customer seating area.

It is particularly effective when preparation stations can be arranged along one service face and supplied from equipment or storage behind the chefs.

Long counters need careful distribution of ingredients and workstations. One chef should not have to travel repeatedly along the entire counter to retrieve shared supplies.

Where several chefs work along the same run, the design must accommodate neighboring cutting positions, equipment access, and replenishment without interfering with service.

L-shaped counters

An L-shaped counter can use two adjoining walls or establish separate working and dining orientations.

Its corner may support a shared ingredient position, create an awkward dead zone, or interrupt chef circulation depending on how equipment is arranged.

Corners should be evaluated for actual preparation and access, not merely used to extend seating.

U-shaped and horseshoe counters

A horseshoe arrangement places guests along multiple sides of a shared chef area.

This can support concentrated interaction between guests and chefs and makes the counter itself a major organizing feature of the dining room.

The available space inside the U must still accommodate chef movement, working surfaces, refrigerated equipment, and access to supporting areas.

KazuNori Westwood, designed by Marmol Radziner, is a documented example: the 1,300-square-foot restaurant uses a solid-maple, 24-seat U-shaped hand-roll bar centered on the chefs.

Curved and custom counters

Curved counters can make productive use of irregular rooms while creating a strong relationship between chef and guest.

At Sushi Takigawa in Fukuoka, CASE-REAL developed a curved ginkgo-wood counter following the building's irregular exterior line. The approximately 19.27-square-meter restaurant keeps the chef central and conceals much of the supporting equipment beneath the counter.

The result illustrates how custom geometry can address real spatial constraints.

It also demonstrates why equipment placement, cabinetry, and access must be resolved carefully when standard rectangular appliances are incorporated into irregular millwork.

Island and freestanding counters

An island counter supports visibility from several directions and may serve guests on more than one side.

Its design must account for utilities entering the island, staff access, equipment concealment, customer circulation, and the location of larger supporting kitchen functions.

An island arrangement should not be selected solely to maximize visibility if the resulting equipment connections or staff movement become impractical.

Recessed and multilevel counters

Recessed refrigerated cases, cutting boards, or preparation surfaces can improve sightlines and separate working tasks from guest dining.

These are construction treatments that can appear in straight, curved, or other counter geometries.

At MF Sushi in Houston, MC2 Architects designed a 25-foot hinoki counter with lowered refrigerated cases and recessed cutting boards. The counter preserves direct interaction between chef and guest while incorporating the equipment and work surfaces necessary for service.

Counter configuration comparison

Scroll horizontally to read the full table →

The correct configuration is the one that supports the restaurant's actual preparation and service requirements within the space available.

05 — Designing the Chef's Workstation: Surfaces, Reach & Ergonomics

Sushi preparation requires extended periods of precise knife work, repeated retrieval of ingredients, rice shaping, and direct handling of finished food.

The chef's working surface must support these activities without unnecessary reaching, awkward posture, or interference from adjacent equipment.

Working height and cutting surfaces

There is no single universally correct sushi-chef counter height.

The appropriate elevation depends on the chef, task, knife technique, cutting-board thickness, and relationship to the guest-facing surface.

The height of the finished cutting surface—not merely the supporting countertop—determines the chef's working position.

A board approximately three-quarters of an inch thick changes that effective elevation. So does a recessed cutting-board opening.

Large cutting boards also require real working space. Their stated dimensions must be evaluated alongside the knife stroke, nearby equipment, tool placement, and the available room for preparation.

For example, ERS carries the Japanese-made Hi-Soft H10B-2 cutting board, measuring 40 × 16 × approximately 0.8 inches.

A larger Hi-Soft H11-A20 board measures approximately 48 × 18 × ¾ inches.

These are materially different working footprints. Specifying the larger board changes the length and depth available for adjacent equipment and may affect the counter's actual usable preparation area.

Cutting motion and working position

The workstation should accommodate the full movement required by the chef's knives.

A long yanagiba requires space for controlled slicing without collision with refrigerated-case doors, condiment containers, neighboring chefs, or the guest-facing handoff area.

ERS's IKKAKU Bessaku 270 mm Yanagiba is an example of the blade length that needs to be considered in a professional sashimi workstation. Knife steel, bevel construction, and sharpening belong in the dedicated knife reference; the concern here is the room required to use and store the tool properly.

Ingredient retrieval

The chef should be able to retrieve commonly used neta, shari, nori, condiments, and finishing tools without repeatedly moving away from the main working position.

Not every item must be within arm's reach at all times. The location should reflect frequency of use, preparation sequence, and whether an assistant or supporting chef replenishes the station.

Storage beneath the work surface can be highly practical, but door and drawer travel must not conflict with chef movement or neighboring equipment.

Ergonomics during extended service

Prolonged standing, repetitive slicing, neck flexion, and frequent reaching all affect working comfort.

OSHA's food-preparation guidance identifies these as relevant ergonomic concerns and recommends placing repeated tasks within convenient working positions, reducing awkward reaching, and selecting task-appropriate working heights.

In a custom counter, critical workstation dimensions should be checked against the actual chef and tasks wherever possible.

A full-size mockup can reveal counter-height, sightline, seating, and reach problems that a plan drawing may not expose.

Shared chef stations

Multi-chef sushi counters require more than several cutting boards arranged in a row.

Shared refrigeration, ingredient trays, knife storage, rice access, and service handoffs must be distributed so one chef's work does not obstruct another's.

Counter length alone does not establish production capacity.

The chef's workstation should be measured by its usable work surface and actual working relationships.

For specific professional knife and cutting-board selection, continue to Professional Sushi Knives, Cutting Boards & Sharpening.

06 — The Guest-Facing Counter: Handoff, Sightlines, Seating & Experience

The sushi counter has two principal users: the chef preparing the food and the guest receiving it.

Their requirements are related, but they are not identical.

The chef needs an effective working height, cutting space, ingredient access, and equipment placement. The guest needs a usable dining surface, comfortable seating, clear access to the food, and an appropriate view of the preparation.

Counter elevation and handoff

Traditional and contemporary sushi counters use different relationships between chef and guest elevations.

Some provide a nearly continuous surface. Others lower the chef's cutting position, raise the guest dining surface, or recess refrigerated display equipment below the principal sightline.

The appropriate relationship depends on the chef's work, the intended presentation, and accessibility.

A recessed cutting board can lower the effective working elevation without requiring the entire counter to sit at the same level.

A recessed sushi case can keep ingredients visible while preventing the glass housing from dominating the interaction.

Neither treatment should be selected independently of the equipment and fabrication requirements.

Sightlines

The chef's preparation may be central to the dining experience, particularly at omakase counters.

At MF Sushi, the lowered display cases and cutting boards create a nearly continuous visual relationship between preparation and guest dining.

At Joji in New York, the relatively small recessed fish display and discreet rice-holding equipment serve a similarly restrained presentation.

These examples do not establish one ideal geometry. They demonstrate a deliberate decision about what the guest should see and what the chef must use.

Seating and service

Dining-surface depth, seating position, guest reach, counter edge design, and the position of plates or other serviceware should be coordinated with the intended manner of service.

A counter where the chef hands nigiri directly across the surface has different handoff demands from a full-service sushi bar where servers deliver much of the menu.

Hand-roll service places particular emphasis on immediacy.

Accessible counter dining

Accessibility must be incorporated into the original counter geometry.

The federal ADA Standards generally require at least 5% of seating and standing spaces at dining surfaces to comply with the applicable accessible-surface requirements, including an accessible dining height of 28–34 inches for adult use and the specified approach and knee/toe clearance.

California has additional provisions affecting dining counters higher than 34 inches, including a qualifying portion of the main counter.

These requirements affect cabinetry, seating, floor space, and the dining experience itself.

A lowered countertop without the necessary approach and clearances is not equivalent to a properly accessible dining position.

The complete selection of plates, bowls, and guest-facing sushi serviceware belongs in ERS's Sushi & Omakase Restaurant Tableware Guide.

07 — Behind the Counter: Supporting Kitchen, Storage & Replenishment

The guest-facing counter depends on refrigeration, ingredient preparation, storage, and service functions that are often better located behind or away from the chef's immediate working area.

The design should distinguish equipment that must be available during final assembly from equipment whose role is receiving, production, replenishment, or long-term storage.

Undercounter refrigeration

Undercounter units can place chilled backup ingredients close to the chef without introducing another countertop display.

Their suitability depends on dimensions, door or drawer access, ventilation, sanitation, and the space available for opening and servicing them.

A 27-inch unit may appear compact in a floor plan. During operation, its door swings outward into the working aisle and employees need room to retrieve containers.

ERS carries the Turbo Air TUR-28SD-N 27-inch undercounter refrigerator, a useful example of a one-section refrigerated cabinet.

Refrigerated preparation tables

Where ingredient staging and refrigeration are needed together, a manufactured refrigerated prep unit may be suitable.

The Turbo Air MST-28-N combines a 27-inch refrigerated cabinet with an upper ingredient-pan arrangement and preparation surface.

For larger multi-chef production, an alternative such as a Turbo Air J Series refrigerated prep table offers a different working length and pan arrangement.

These products should be evaluated for the restaurant's actual ingredient handling, temperature requirements, pan layout, and available space. Their suitability should not be inferred solely from their general classification as sandwich/salad preparation equipment.

Fish preparation and primary storage

The location of seafood breakdown and bulk storage should reflect receiving arrangements, staff responsibilities, and the intended volume of preparation.

An omakase counter may display selected neta near the chef while using separate refrigerated storage for most of the inventory.

A high-volume sushi production kitchen may use distributed prep stations and larger refrigerated storage away from the visible counter.

Rice and hot-kitchen support

Rice washing, cooking, mixing, and seasoning may be located in the supporting kitchen, with finished rice brought to the counter as required.

The same applies to hot-food components prepared on fryers, broilers, griddles, or other equipment.

If the menu requires large amounts of cooked ingredients, the sushi station's relationship to the hot kitchen becomes a central planning decision.

Ice and other support equipment

Ice production and storage may be necessary for seafood handling or other restaurant operations, but the ice machine itself does not necessarily belong immediately behind the chef.

For example, the Hoshizaki F-300BAJ flake ice machine is a substantial supporting appliance, not a compact ingredient dispenser.

Its physical footprint, water, drainage, electrical, ventilation, and service requirements belong in the wider kitchen-equipment plan.

The correct arrangement keeps the chef's essential equipment accessible while allowing larger production and support tasks to function efficiently outside the visible preparation area.

For refrigeration planning beyond workstation integration, see Seafood Refrigeration, Freezers & Cold-Chain Equipment.

09 — Integrating Rice, Nori, Ingredients & Preparation Tools

The chef's workstation must also accommodate ingredients and utensils with very different physical requirements.

Prepared sushi rice, chilled neta, dry nori, condiments, cutting tools, and rolling accessories should not be organized as though they were interchangeable countertop items.

Rice production versus chef-side holding

Rice washing, cooking, seasoning, and staging may require dedicated equipment and working space outside the guest-facing counter.

The chef needs appropriate access to finished shari during service, but the cooker itself may belong elsewhere.

A large traditional hangiri can occupy significant working space. ERS's Japanese-made I-654-60 wooden sushi rice tub, approximately 23½ inches in diameter, illustrates why rice mixing and seasoning should be planned as real preparation tasks rather than assumed to fit wherever room remains.

Commercial electric rice warmers perform a different function.

The Zojirushi THA-803S is an 8-liter commercial warmer measuring approximately 18⅛ × 15 × 15⅜ inches. It holds previously cooked rice; it is not a rice cooker.

The appropriate rice holding method, location, and handling practice must be chosen for the actual sushi production process.

For full rice-production equipment selection and tested cooker performance, use Sushi Rice Equipment, Hangiri & Shari Production and ERS's Commercial Rice Equipment Research.

Nori access and protection

Nori storage should be protected from unwanted moisture and organized around the chef's repeated movements.

ERS's NC-1 nori container, measuring approximately 8½ × 5⅛ × 3¾ inches, and the larger NC-2 container, approximately 9 × 8½ × 4½ inches, illustrate how storage size and lid clearance affect placement.

A hinged container needs enough room to open and operate without interfering with other equipment.

Mats, paddles, and smaller utensils

Rolling mats should be located where maki preparation occurs, with storage and cleaning arrangements appropriate to their material and use.

ERS offers traditional bamboo makisu and alternatives such as the FMK-MG plastic sushi rolling mat.

Other useful workstation accessories include the 23 cm bamboo rice spatula and angled fish-bone tweezers.

These pieces require relatively little counter space individually, but a poorly organized collection of them can materially reduce the usable preparation surface.

The correct arrangement reflects the task, frequency of use, ingredient characteristics, and cleaning process—not an arbitrary rule that every item must remain visible on the counter.

08 — Integrating Refrigerated Sushi Cases into the Counter

A refrigerated sushi display case is one of the most consequential equipment selections affecting the physical counter.

Case width alone is not enough to specify the installation.

The selected unit determines the required counter support, condenser location, airflow, electricity, drainage, access, cleaning arrangements, and potentially the relationship between the chef and guest.

Self-contained and remote refrigeration

Self-contained refrigerated sushi cases include the refrigeration machinery within the cabinet.

Remote-refrigeration displays are designed for connection to a separate refrigeration system and therefore require additional mechanical design and coordination.

These are different installation arrangements, even when the cases appear similar from the dining room.

Current Hoshizaki HNC-SLH example

Consider the Hoshizaki HNC-150BA-L-SLH, a self-contained refrigerated sushi showcase with a left-side condenser when viewed from the front.

Its current manufacturer specifications include:

Scroll horizontally to read the full table →

The manufacturer's installation instructions also establish several conditions that directly affect the surrounding construction.

Condenser clearance

Hoshizaki requires at least 6 inches of clearance between the condenser air inlet/outlet and neighboring walls or equipment.

The rear of the case must allow access to the power switch, louver, and air filter. The manufacturer also requires open space above the showcase.

The condenser cannot simply be enclosed behind attractive millwork.

Full-base support

The unit must sit on a stable, level surface that adequately supports the entire bottom.

The manufacturer warns that supporting only part of the bottom can cause deformation, damage, or equipment failure.

The supporting counter therefore has to be fabricated for the case's actual physical requirements.

Counter sealing

Hoshizaki instructs that the perimeter where the showcase contacts the counter be sealed with silicone.

That instruction must be coordinated with the requirements for maintaining condenser airflow and equipment access.

Electrical connection

The installation instructions call for an appropriately rated independent, grounded electrical supply using the unit's NEMA 5-15P connection.

The receptacle location must permit safe connection without obstructing maintenance access.

Drainage

The model provides front drainage connections and a hose arrangement.

The manufacturer's instructions require more than 2 vertical inches of air gap between the hose outlet and the receiving floor drain or sink. The final installation must also satisfy applicable local plumbing requirements.

Heat exposure

Direct sunlight, nearby cooking appliances, heating vents, and high-intensity lamps can introduce unwanted heat and impair operating conditions.

A display case positioned beside a fryer, near a hot preparation station, or underneath intense lighting must be evaluated against the manufacturer's ambient and installation requirements.

Cleaning and maintenance

The rear filter, condenser, controls, sliding doors, drain provisions, and equipment connections need to remain accessible.

Custom cabinetry that prevents filter removal or requires dismantling the counter for ordinary maintenance is not an acceptable integration.

Technical references: Hoshizaki HNC-SLH cut sheet · Hoshizaki installation manual.

Display refrigeration is not primary overnight storage

Hoshizaki identifies the HNC-SLH as a refrigerated display case, not equipment intended for overnight food storage.

Its instructions also call for sushi materials to be appropriately refrigerated before display.

The refrigerator used for primary storage and the case used during service therefore serve different roles. Their capacities and operating requirements must be specified accordingly.

Alternative self-contained case configurations

ERS's refrigerated sushi-case assortment includes several alternatives illustrating why exact model selection matters.

The Turbo Air SAK-50R-N is a curved-glass, right-condenser self-contained case with an actual width of approximately 48¼ inches.

The Turbo Air SAS-50R-N uses straight glass, with a different enclosure and dimensions.

ERS also carries larger cases, including the Hoshizaki HNC-180BA-R-SLH at approximately 70.9 inches wide, with a right-side condenser.

These products illustrate differences in width, glass design, condenser orientation, and counter integration. They do not share one interchangeable fabrication specification.

Remote-refrigeration displays

The Turbo Air TSSC-4 is a 48-inch remote-ready sushi display, supplied pre-piped for a separate refrigeration connection.

This configuration introduces mechanical requirements beyond those of a plug-in self-contained case.

The refrigeration system, piping, service access, and installation responsibilities must be resolved by the project team.

Before the case is ordered

The equipment supplier and fabricator should confirm the exact model, full dimensions, condenser position, required clearances, utility connections, drainage, counter support, access, and cleaning provisions.

If the proposed case changes, the affected fabrication and utility details should be reviewed before the substitution is accepted.

For full manufacturer and model selection, see Sushi Display Cases & Refrigerated Neta Cases.

10 — Counter Materials, Wood, Stainless Steel & Fabrication

Traditional Japanese sushi-counter craftsmanship and commercial foodservice construction are closely related, but they are not interchangeable.

The material must be appropriate to the actual surface function.

Traditional wooden counters

Hinoki and other carefully selected woods are associated with traditional Japanese counter construction, valued for their appearance, texture, and presentation.

MF Sushi's architect documented a hinoki counter formed from laminated planks, while CASE-REAL used ginkgo wood for Sushi Takigawa's compact curved counter.

These projects illustrate the range of wooden counter construction; they are not evidence that all wood species or finishes are interchangeable in food-preparation applications.

Guest surfaces and preparation surfaces have different requirements

A finished wooden surface used for guest dining is not necessarily subject to the same conditions as the chef's cutting area.

California Health and Safety Code §114132 generally restricts wood as a food-contact surface, subject to specified exceptions, including qualifying hard maple or equivalently hard close-grained wood for certain uses such as cutting boards and cutting blocks.

The appropriate material and finish depend on the actual intended use, applicable requirements, and cleaning method.

A removable commercial cutting board may be the proper working surface above a finished wooden counter.

Stainless steel and commercial preparation surfaces

Stainless steel is widely used for commercial working surfaces, sinks, supporting counters, and foodservice equipment because it can be fabricated into cleanable, durable components when appropriately specified.

Its grade, fabrication, seams, joints, support, and finish matter. “Stainless steel” alone is not a complete construction specification.

Other materials, including stone, engineered solid surfaces, rubber and polymer cutting boards, ceramic finishes, and lacquered decorative elements, must likewise be evaluated according to function.

Commercial cutting boards

ERS's AG-114 Japanese rubber cutting board measures approximately 48 × 18 inches and is materially different from a fixed wooden counter surface.

A cutting-board specification should address its actual dimensions, material, support, usable cutting area, cleaning requirements, and replacement.

Fabrication details

Custom sushi-counter fabrication must account for:

• Finished chef and guest elevations.
• Structural support and rigidity.
• Food-contact applications and cleanability.
• Equipment openings and mounting.
• Joint treatment and moisture exposure.
• Recessed cutting boards and removable inserts.
• Service panels, filters, and access to equipment.
• Concealed utility runs.
• Cleaning access and equipment replacement.

A counter may look continuous from the dining room while requiring several different construction materials and removable components behind the chef's working area.

The most successful fabrication preserves the intended aesthetic without compromising the equipment and preparation functions beneath it.

For deeper treatment of Japanese materials and traditional sushi service objects, see The Craft and Objects of the Sushi Restaurant.

11 — Sinks, Handwashing, Sanitation & Drainage

Sushi-counter plans must distinguish handwashing, food preparation, warewashing, janitorial cleaning, and equipment drainage.

These are separate functions with different requirements.

Handwashing

Accessible handwashing facilities are required where applicable to food preparation and related employee activity.

They must be conveniently located, unobstructed, and available during service.

A handwash sink concealed behind millwork, blocked by an opened refrigerator door, or used for unrelated activities does not provide an effective working arrangement.

The location should be evaluated with the actual chef and support staff movements.

Food-preparation sinks

Where the restaurant's preparation methods require washing, rinsing, soaking, thawing, or similar food-preparation activities, the appropriate food-preparation sink must be included in the facility plan.

Los Angeles County's retail-food construction guidance describes a separate food-preparation sink with minimum bowl dimensions of 18 × 18 × 12 inches, together with drainage and work-area requirements, where applicable.

The complete preparation operation—not merely the visible sushi counter—determines where this sink is required.

Warewashing

The restaurant must provide appropriate facilities for cleaning its utensils, smallwares, equipment, and serviceware.

For applicable commercial food facilities, Los Angeles County describes a three-compartment warewashing sink and associated drainboards.

Warewashing is often better located outside the guest-facing chef counter, but the path taken by used dishes, utensils, and equipment should be planned.

Janitorial facilities

Cleaning tools and janitorial wastewater require suitable facilities. They should not be treated as interchangeable with handwashing or food-preparation fixtures.

Equipment drainage

Refrigerated sushi cases and other appliances may require specific drain or condensate arrangements.

These requirements must be checked for the exact unit and coordinated with applicable plumbing rules.

The drain provisions of the Hoshizaki HNC-SLH case, for example, are specified in the installation manual and should not be generalized to every case.

Displayed food protection and sanitation

The position of ingredients, displayed neta, customers, sinks, splashing, and active preparation affects the counter's sanitary design.

The arrangement must provide appropriate food protection and permit routine cleaning without damaging equipment or finished materials.

LA County's Construction Requirements for Retail Food Facilities provide a concrete local reference for these functions.

Detailed jurisdiction-specific requirements belong in Equipment Specifications, Food-Safety Controls & Commercial Requirements.

12 — Electrical, Refrigeration Airflow, Lighting & Ventilation

The appearance of a finished sushi counter can conceal considerable infrastructure.

Power, refrigeration airflow, drainage, lighting, and ventilation must be coordinated with the actual equipment and the way the counter is used.

Electrical service

Every powered appliance should be specified using its current electrical requirements.

These include the rated voltage, phase, current, plug or connection, manufacturer power-supply requirements, and the location of any necessary disconnect or receptacle.

The design must permit the actual equipment to be connected and serviced without conflict with cabinetry, sinks, cleaning water, or other working components.

Refrigeration airflow and heat

Self-contained refrigeration rejects heat into the surrounding environment.

The manufacturer determines which faces require intake, exhaust, access, or clearance.

An appliance that fits physically inside a counter may still be improperly installed if its condenser is enclosed.

Hot equipment, strong sunlight, HVAC outlets, and intense lighting can also change local operating conditions.

The surrounding cabinetry must be designed around the refrigeration machinery—not merely around the appliance's visible external shape.

Task lighting

Sushi counters often employ restrained ambient lighting to emphasize food presentation and the chef's work.

That lighting must be distinguished from illumination needed for safe and effective food preparation.

California's food-facility requirements include 50 foot-candles at relevant work surfaces where food employees work with knives and other equipment presenting safety considerations.

A visually intimate dining room can still provide suitable task lighting at the chef's cutting surface.

Lighting should also avoid unwanted glare and heat at refrigerated cases.

Ventilation and hot-food equipment

Not every sushi counter requires a full cooking exhaust hood.

The equipment and menu determine what ventilation is required.

A cold-preparation counter differs from a workstation incorporating grilling, frying, broiling, or other heat-producing equipment.

Ventilation, mechanical services, and refrigeration placement must be coordinated with the actual cooking activities.

Utility coordination at a glance

The exact selected equipment must govern the utility schedule.

13 — Accessibility, Plan Review & Construction Requirements

A commercial sushi counter must be designed for actual use and for the requirements applicable to its location.

Custom millwork, food-contact surfaces, fixed equipment, accessible dining, plumbing, ventilation, and sanitation cannot be resolved independently after the physical counter is built.

Dining surfaces and accessible participation

Federal ADA Standards generally require at least 5% of seating and standing spaces at dining surfaces to comply with the applicable accessibility requirements.

For adult dining surfaces, the relevant height range is generally 28–34 inches above the finished floor, together with the required clear floor space and knee/toe clearance.

California's current building-code requirements add an important provision for high dining counters.

Under California Building Code §11B-226.3, where food or drink is served for consumption at a counter exceeding 34 inches in height, a portion of the main counter at least 60 inches long must comply with the applicable accessible dining-surface height requirement.

This matters directly to continuous sushi counters, hand-roll bars, omakase counters, and custom dining surfaces where most seats occupy one principal counter.

Accessible seating and circulation should be integrated into the same design from the beginning.

A nearby accessible table should not automatically be assumed to satisfy every main-counter requirement.

Food-contact surfaces and equipment sanitation

Commercial surfaces and equipment must meet the applicable requirements for their intended use.

Certification of a refrigerated appliance does not establish approval of all the custom millwork enclosing it.

Similarly, an attractive finish does not automatically qualify it as a food-contact preparation surface.

Materials, equipment mounting, cleanability, installation and use must be resolved in the context of the complete facility.

Plan review and documentation

For applicable retail-food construction and remodeling in Los Angeles County, plans and specifications are submitted for review before construction.

Relevant documentation may include:

• Scaled layout plans.
• Equipment schedules and manufacturer cut sheets.
• Plumbing and drainage details.
• Electrical and mechanical information.
• Finish and construction specifications.
• Sink and warewashing arrangements.
• Menu and operating information.
• Other project-specific documents required by the reviewing authority.

The review process varies by jurisdiction and project.

The commercial responsibility is clear: equipment selections must provide accurate information to the professionals preparing and reviewing the project.

Who resolves which part?

Scroll horizontally to read the full table →

These responsibilities may overlap according to the project contract, but they should not be left ambiguous.

For deeper technical and regulatory reference, see Equipment Specifications, Food-Safety Controls & Commercial Requirements.

14 — Sushi Bar Arrangements by Restaurant Concept

The same design principles produce different counter layouts depending on the operating model.

The following distinctions concern physical counter requirements—not the complete equipment inventory of each restaurant type.

Traditional full-service sushi bar

The traditional full-service sushi restaurant may combine a visible chef counter with tables, servers, a larger hot kitchen, and substantial supporting preparation.

Display refrigeration, chef workstations, rice holding, guest handoff, and adjacent storage must be coordinated with service from the rest of the kitchen.

A linear or L-shaped counter can provide a clear chef-to-guest relationship, but the supporting functions remain central to its performance.

Omakase and Edomae counter

The counter becomes an important part of the dining experience.

Chef visibility, preparation-surface elevations, ingredient presentation, material selection, lighting, and precise food handoff receive particular attention.

Custom woodworking and recessed equipment may enhance the intended experience.

The result should still provide the chef with appropriate preparation access, sanitation, and serviceability.

MF Sushi and Joji demonstrate different approaches to accomplishing this without relying on identical layouts.

Hand-roll and temaki counter

Immediate service drives the physical arrangement.

Rice, nori, fillings, cutting and assembly are positioned around direct interaction between chef and guest.

KazuNori's U-shaped counter and Yunomi's compact counter-oriented layout are useful examples of a service model influencing the architecture.

The counter should allow finished hand rolls to reach the guest without an unnecessary transfer sequence.

High-volume sushi production

When multiple chefs or employees are producing large numbers of items, the design places greater emphasis on task distribution, common ingredient access, production capacity, and replenishment.

More working positions may be needed, with additional support refrigeration and preparation surfaces.

The best arrangement may look quite different from a chef-centered tasting counter.

Takeout and grocery sushi

Packaging, labeling, staging, and refrigerated retail handling are major physical functions.

The workstation needs an efficient connection between assembly and downstream handling.

Guest-facing display may exist, but it does not automatically determine the production-counter geometry.

Conveyor and automated service

Conveyor-sushi restaurants require coordination between kitchen production, delivery machinery, plate standards, guest access, dish return and mechanical service.

The counter and dining layout may be substantially governed by those equipment arrangements.

An automated delivery line cannot simply be added to a traditional chef counter without reconsidering the working space and service routes.

15 — Costly Design Mistakes, Retrofits & Long-Term Serviceability

The most expensive sushi-counter problems often result from suitable components that were never properly coordinated.

The equipment may be correct. The counter may be beautifully fabricated. But the completed installation can still be difficult to operate, clean, or maintain.

Design for the equipment's entire life

Every installed appliance eventually requires cleaning, inspection, servicing, or replacement.

The counter should allow those activities without unnecessarily damaging cabinetry, finishes, or adjacent equipment.

For refrigerated cases, consider filter access, condenser service, drain connections, glass-door movement and complete appliance removal.

For undercounter equipment, consider access to controls, compressors, casters, doors and electrical connections.

For removable preparation surfaces, consider replacement, cleaning, storage and the condition of the supporting counter.

The objective is not to future-proof the counter against every imaginable appliance. It is to avoid making normal servicing or foreseeable replacement an unnecessarily destructive project.

Evaluate substitutions physically

A replacement appliance should be evaluated for its actual footprint, airflow, doors, plumbing, power, operating conditions and service requirements.

Two products with similar nominal widths may not fit the same construction.

This is especially important when equipment is ordered late or when a preferred model becomes unavailable during a project.

The earlier these dependencies are resolved, the less likely the project is to require expensive revisions during fabrication or installation.

For ongoing maintenance and replacement considerations, see Sushi Equipment Maintenance, Cleaning & Replacement Parts.

16 — From Counter Concept to Equipment & Fabrication Specification

A sushi-counter project becomes ready for purchasing and fabrication when the operating plan, equipment selections, construction drawings, and utility requirements agree.

A floor plan and a shopping list are not enough.

Define the operating requirements

The initial brief should identify the restaurant concept, menu, number of chef positions, intended guest service, supporting preparation, refrigerated storage, rice production, and expected production demands.

These determine the equipment categories and preliminary spatial relationships.

Establish the counter layout

Working drawings should identify the chef preparation areas, guest surfaces, counter geometry, equipment positions, supporting storage, circulation, and relevant accessibility arrangements.

The layout must be checked against equipment in operation—not only its closed or idle footprint.

Assemble an equipment schedule

The schedule should identify each major appliance and construction-dependent item by its intended function, proposed manufacturer and model, and the specifications required to coordinate it.

An illustrative sushi-counter schedule might contain:

This is an illustrative schedule, not an instruction to purchase all listed categories for every sushi counter.

Obtain current manufacturer documentation

For construction-dependent equipment, obtain actual cut sheets and installation instructions.

The documents should establish dimensions, utility requirements, mounting, clearances, service access, and any relevant operating limitations.

A product description, manufacturer family name, or nominal width should not substitute for the correct model's installation information.

Coordinate the fabricator and project team

Counter elevations, equipment openings, support, surfaces, cabinetry, plumbing, electricity, mechanical equipment, accessibility and finish construction must reflect the selected appliances and operating needs.

Changes made by one participant should be communicated wherever they affect other parts of the work.

An equipment substitution that changes condenser position, required clearance, or drain location is a construction change—not merely a purchasing change.

Complete applicable review and release

Required drawings, equipment information and approvals should be resolved according to the project.

Equipment purchasing and custom fabrication can then be released against a coordinated specification.

Lead times, installation arrangements and delivery requirements also deserve attention, particularly when equipment must be available for field measurement or millwork completion.

Verify the installed counter

At installation and before regular service, confirm:

• Actual equipment fit and stable support.
• Proper access to doors, drawers and filters.
• Working condenser airflow and ventilation.
• Electrical and plumbing connections as specified.
• Correct placement and usability of chef working surfaces.
• Guest dining access and seating.
• Practical cleaning and maintenance access.
• Equipment documentation and service information.

The most revealing final check is whether the chef can actually work as intended at the completed counter.

What to provide when sourcing sushi-bar equipment

A productive equipment inquiry should include the restaurant concept, project location, menu, preliminary layout or drawings where available, intended chef positions, relevant dimensions, and any known manufacturer/model preferences.

If the project already has equipment or millwork specifications, provide those documents so product dimensions, orientation, utilities and installation requirements can be evaluated accurately.

Quick Reference: Common Sushi Bar Design Questions

What is the best height for a sushi chef's counter?

There is no universal sushi-chef work height. Determine the effective preparation elevation from the chef's task, stature, cutting-board thickness, posture and equipment arrangement. Guest dining and accessible dining surfaces have separate requirements.

Should a refrigerated sushi case be recessed?

Recessing can improve sightlines and visual integration, but the counter must accommodate the exact case's support, condenser airflow, drainage, power, cleaning and service requirements. A countertop model cannot automatically be installed in an enclosed recess.

Can a sushi display case replace overnight refrigeration?

Not necessarily. For example, Hoshizaki identifies its HNC-SLH refrigerated showcase as equipment for display during service rather than overnight food storage. The restaurant needs a complete refrigeration plan suitable for the actual food and operation.

What is the best sushi-counter layout?

Straight, L-shaped, U-shaped, curved, island and production-oriented layouts can all work. The appropriate arrangement depends on chef positions, service, guest interaction, equipment, available space and supporting kitchen relationships.

Can a sushi restaurant use a wooden counter?

Yes, wooden counters are used in traditional and contemporary sushi restaurants. However, the intended role of each surface matters. Decorative wood, guest dining surfaces, removable cutting boards and direct food-preparation surfaces must be evaluated under applicable materials and sanitation requirements.

When should sushi-bar equipment be specified?

Construction-dependent equipment should be selected or its acceptable physical requirements fixed before the surrounding millwork, utilities and installation details are released. Exact models and manufacturer documentation must be coordinated with the project drawings.
