A sushi counter is one of the few places in hospitality where the back of house is also the front of house. Guests sit close enough to watch a knife move through a block of salmon, and everything behind that glass — the trays, the drawers, the ice, the temperature — becomes part of the performance. That single fact changes how you plan cold storage. A standard kitchen hides its compromises behind a wall; a sushi bar puts them on display. The cold chain from delivery to service has to be short, visible and easy to manage at pace, and every piece of refrigeration near the prep counter needs to earn its footprint during every single service.
So the brief is not simply “buy a fridge and an ice machine”. It is a layout problem: how much cold storage sits in view, how much sits behind the counter, where ice is made, where it drains, and how staff move between all three without crossing paths or leaving fish sitting in melt water. Get that structure right and the equipment list almost writes itself.
Why a Visible Prep Counter Changes the Cold Storage Brief
The customer’s sightline dictates the layout. When the counter is glass-fronted, every piece of gear behind it is a merchandising decision as much as a refrigeration one. That usually pushes operators towards a two-zone approach: a shallow, immaculate display zone at the front, and a working cold store behind it that does the heavy lifting. Confusing the two is the most common mistake in new sushi fitouts — a glass case packed with backup trays will struggle to recover temperature between service bursts, fogs up at the wrong moment and looks cluttered from the guest’s side of the glass.
Sashimi-grade refrigeration is the spine of the operation, and the numbers matter more than the styling. Sashimi prep fridges designed to hold product in the 0–2°C band, refrigerated benches with topping rails so garnish and portioned fish sit in the cold rather than on the bench, drawer refrigeration under the counter for backup trays, and walk-in cold rooms with precise temperature control for bulk holding between deliveries. Where a venue breaks down whole fish or portion-fillets in-house, a blast chiller earns its place too, because rapid chilling protects texture in a way that slow cooling never does.
Then there is the display layer itself: glass-front refrigerated counter cases for omakase-style service, refrigerated belt-train cases where sushi train volume is the model, and curved-glass merchandising cabinets for takeaway shopfronts. These are not interchangeable pieces. A belt-train venue runs on throughput and presentation at scale; a twelve-seat counter runs on precision and a very small number of pieces held perfectly. Purpose-built Japanese equipment behaves differently to converted Western kit — the dimensions, the temperature bands and the way product is accessed are all tuned to the way sushi is actually worked.
Two practical details catch people out. First, under-bench refrigeration rejects heat into the room, right where guests are seated and staff are working. Allow proper ventilation gaps at the rear and sides rather than boxing units into a sealed joinery cavity, or the compressor works harder and the counter becomes uncomfortable. Second, plan the display case as the last metre of the cold chain, not the storeroom. A supplier with genuine range across refrigeration and food display — Atlantic Equipment stocks more than 140 brands from its Granville warehouse and showroom and has been supplying NSW kitchens since 2002 — is worth talking to early, because the case, the prep fridge and the cool room all need to agree with each other.
Ice Around the Counter: Display, Drainage and the Two-Ice Rule
Ice is treated as an ingredient in a sushi bar, not as a background utility. It beds down display product, it chills fish during breakdown, it fills counter wells for service, it goes into drinks, and it is often the fastest way to pull temperature out of a just-delivered fillet. That versatility is exactly why it needs rules. The operators who stay out of trouble generally run a two-ice system: one supply for anything that touches raw fish or sits in a display bed, and a separate, clearly labelled supply for beverages. Different bins, different scoops, different storage positions, and a team briefed on which is which. During a Friday night rush, ambiguity around ice is how cross-contamination happens.
Drainage is the second non-negotiable. All ice melts, and melt water is the enemy of fish quality — product sitting in a pool of it loses texture and develops off notes quickly. Every ice well, display bed and fish tray wants to drain, either to a grated floor waste or into a removable tray that a staff member can empty mid-service without dismantling the counter. Sloped bases and racks that hold product above the melt are worth far more than a deeper well. A shallow, drained, insulated well beats a deep one every time, because it is easier to clean, less prone to condensation and far less of a slip hazard at the front of house.
Ice-making equipment needs its own thought. Air-cooled machines discharge heat and moisture into the room, so mounting or positioning one directly above or beside a prep counter creates fogging, condensation on the glass and a warmer working zone — the opposite of what the counter needs. Plumbing, drainage and a water supply all have to be resolved before the joinery is fabricated, not after. Covered storage bins set within arm’s reach but off the prep surface, with scoops stored outside the ice, keep the workflow tight without compromising hygiene.
It is also worth sizing ambition against space. Ice wells eat bench depth, and a counter that is 90 per cent ice storage leaves nowhere to actually work. If ice production, storage and drainage are part of the fitout, raise them with your equipment supplier alongside the refrigeration plan rather than treating them as a separate plumbing conversation later.
Working the Radius: Layout, Access and Practical Fitout Decisions
Draw an imaginary arc about 900 millimetres out from where the cutter stands. Everything that matters should live inside it — the prep fridge, the drawer unit, the ice well, the rice warmer, the garnish rail. Anything outside that arc is a walk, and walks are what slow a counter down at 7pm on a Saturday. The sequence to design around is simple and unforgiving: receive, store, break down, hold, serve. Every extra step between those stages is a temperature rise and a delay.
Pass-through refrigeration between the back-of-house cool room and the counter is one of the quieter wins in a busy venue, because it lets staff restock without walking through the guest area with open trays. Refrigerated drawer units under the counter do similar work in a smaller footprint, keeping backup portions cold and instantly accessible without adding another reach-in door to the sightline. Whatever you choose, think hard about service access: if a unit fails, can it be pulled out, repaired and returned without demolishing the counter? Castors where possible, removable kick plates, sealed joins and coved corners all make the difference between a twenty-minute fix and a two-day outage. Power deserves the same discipline — dedicated circuits and isolators, not a daisy chain of adaptors under the bench.
For operators comparing options, walking the Granville showroom with a marked-up counter plan is more useful than browsing specifications in isolation, and the team can talk through delivery, installation and after-sales support in the same visit. Most stock ships within a week from the local warehouse, and custom cool rooms and freezer rooms can be built to suit the site where a standard unit will not fit. Finance is available through SilverChef Rent-Try-Buy, which Atlantic is an authorised dealer for, and the live catalogue is the place to check current pricing and availability rather than working from last season’s numbers. Reviewing sushi bar display and prep equipment early in the design process tends to shorten the whole build, because the case dimensions, the refrigeration clearances and the ice requirements all get resolved before anyone signs off on joinery drawings.
The last thing worth locking in early is monitoring. A simple probe and a written temperature log, checked at open, mid-service and close, tells you more about whether your cold storage is actually working than any specification sheet — and on a visible counter, where the guest can see the product and the process at the same time, that record is the difference between confidence and guesswork.
