Quick Answer
A UK commercial kitchen needs 304-grade stainless steel work tables at 900mm height with 600 or 700mm depth, plus separate sinks for food preparation, washing up, and hand washing — three sinks minimum under food hygiene rules. Work tables run £285–£535 and sink units £437–£1,188 depending on bowl count and drainer.
Caterzone supplies stainless steel work tables, sink units, and wall shelving to UK restaurants, takeaways, cafés, and commercial kitchen fit-outs, and stainless steel furniture is the part of a kitchen budget that gets cut first and regretted longest. Cooking equipment fails visibly; a badly specified bench sags, harbours water, and quietly costs you hygiene rating points for years.
This guide covers 304 versus 430 stainless grades, correct bench heights and depths for UK kitchens, how many sinks the regulations actually require, the difference sink bowl depth makes, wall shelving loads, flat-pack versus welded construction, and what to budget for a fit-out. Browse the stainless steel kitchen furniture range as you read.
What grade of stainless steel should a commercial kitchen use?
Use 304 grade for anything touching food, water, or salt, and accept 430 only for dry, non-contact areas.
304 (also called 18/10 or A2) contains around 18% chromium and 8–10% nickel. The nickel is what gives it real corrosion resistance against salt, acid, and chlorine-based sanitisers. It is non-magnetic, holds a consistent finish, and it is the grade every UK commercial kitchen bench, sink, and food-contact surface should be. Expect to see it quoted as 304 or 18/10 on the specification sheet — if a supplier will not state the grade, assume it is not 304.
430 (18/0) contains chromium but effectively no nickel. It is magnetic, cheaper by roughly 25–35%, and adequate for wall cladding, shelf brackets, and equipment stands in dry areas. Put it near a sink, a dishwasher, or salt and it will develop rust spotting within months — usually first at the welds and cut edges.
316 (marine grade) adds molybdenum for still greater resistance. It is worth the premium only in genuinely aggressive environments — a fish preparation room, a heavy brining operation, or a coastal site with salt-laden air. For most kitchens it is money better spent elsewhere.
Gauge matters as much as grade. A 1.0mm top on a 700mm deep bench will drum and flex under a chopping board; 1.2mm is the sensible commercial minimum and 1.5mm is what heavy-duty benches use. Ask for the gauge in millimetres, because "heavy duty" on its own means nothing.
What height and depth should commercial work tables be?
UK commercial benches are made at 900mm working height as standard, with adjustable feet giving roughly 850–900mm, and this is not arbitrary.
900mm suits a standing worker of average height for chopping and general preparation. Two adjustments are worth making. For heavy tasks needing downward force — jointing, kneading, portioning large primals — 850mm is more comfortable and safer on the back. For fine, detailed work such as patisserie decoration, 950mm reduces the stoop. If your team is consistently tall or short, adjust the feet and standardise across the kitchen rather than mixing heights.
Depth is the more important decision and the one operators get wrong.
- 600mm depth suits corridors, wall runs behind a cooking line, and sites where floor space is genuinely tight. It takes a standard 600mm gastronorm layout but is shallow once a chopping board and a container are on it.
- 700mm depth is the better general-purpose choice. It gives room for a board at the front and containers at the back without reaching over the work.
- Island / centre tables at 700–800mm allow two people to work from opposite sides.
Standard lengths run 800, 1000, 1200, 1400, 1600, 1800, and 2000mm. Plan the run in these increments rather than ordering a bespoke length, which typically costs 40–60% more for no functional gain.
Two features worth paying for: a 100mm upstand (splashback) where the bench meets a wall, which stops water and debris getting into the gap behind — an EHO favourite — and a bottom shelf, which roughly doubles usable storage and stiffens the frame considerably. Benches with a bottom shelf and cross-bracing flex far less than four-leg-only tables of the same gauge.
How many sinks does a UK commercial kitchen need?
UK food hygiene law requires enough sinks for the separate activities you carry out, and in practice that means a minimum of three distinct sinks in most kitchens.
Under retained Regulation (EC) 852/2004, Annex II, food premises must have an adequate number of sinks for washing food, and a separate adequate number of washbasins for washing hands. The practical breakdown that inspectors expect:
- A dedicated hand wash basin with hot and cold water, liquid soap, and disposable towels. It must be used only for hand washing — not for rinsing kit — and it must be within easy reach of every preparation area. A kitchen with no dedicated hand basin is one of the fastest routes to a low hygiene rating.
- A food preparation sink for washing vegetables, salad, and produce.
- A wash-up sink — normally double bowl with a drainer, or a single bowl plus dishwasher.
Add a fourth in specific cases: a separate sink for raw meat or fish handling where cross-contamination risk demands it, and a cleaner's sink or mop sink (which must never be in the food preparation area) for cleaning water.
Sink bowl dimensions matter more than most people expect. A wash-up bowl should be at least 500 x 400 x 300mm deep so that a 1/1 gastronorm pan and a standard sheet tray can be fully submerged — a 200mm-deep bowl means you cannot properly wash the trays you use every day. Standard commercial dishwasher sink units are built at 1,200–1,800mm long with the bowl offset left or right, so the drainer feeds directly into a pass-through machine.
Specify the drainer side before ordering. "Right-hand drainer" means the drainer sits to the right of the bowl as you face it, and getting it backwards on a fitted run means either a return or a compromised workflow for the life of the kitchen.

| Wall shelf | 1200 x 300mm | 304, 1.0mm | 40–60kg UDL per bracket pair | £85–£160 |
As a planning figure, a small UK takeaway kitchen fit-out in stainless steel — three benches, a wash-up sink, a prep sink, a hand basin, and four wall shelves — lands at roughly £2,400–£3,200. A 60–80 cover restaurant with a longer line and a proper dishwasher station typically runs £5,000–£8,000.
Flat pack or fully welded — which is right?
Flat pack is the right default for most kitchens; welded is worth the premium only in specific situations.
Flat pack benches arrive as a top, four legs, a shelf, and a bag of fixings, and assemble in 15–25 minutes with a spanner. They save 25–40% on delivery cost against a welded unit of the same size, fit through a standard 762mm doorway, and can be dismantled if you move site. Modern flat pack designs using bolt-through leg sockets and a folded, box-section top edge are genuinely rigid — the old objection about wobble largely belongs to older designs.
Fully welded benches have no joints for water or debris to enter, which makes them slightly easier to clean and slightly better in a wet room or a high-risk area. They are stiffer under very heavy point loads such as a large mincer or a dough mixer. They also cost more to deliver, cannot be taken apart, and may not fit through your doors.
The practical rule: use flat pack for general preparation benches and wall runs, and specify welded for the wash-up area, for any bench carrying a heavy fixed machine, and for high-risk rooms where seam-free surfaces are part of your HACCP justification.
Whatever you choose, insist on adjustable feet. UK commercial kitchen floors are rarely level, particularly in converted premises, and a bench that rocks will spill liquids and eventually crack a weld. Adjustable feet also let you set a consistent 900mm across an uneven floor, and lift the frame clear so you can clean underneath — which is exactly what the inspector will check.
Wall shelving, loading, and cleaning
Wall shelves are the cheapest storage in a commercial kitchen and the most commonly overloaded.
A standard 300mm-deep stainless wall shelf on a pair of brackets carries roughly 40–60kg uniformly distributed, provided it is fixed into masonry with appropriate anchors. Plasterboard alone will not hold it — you need to hit studs or use proper cavity fixings rated for the load, and in a commercial kitchen the sensible answer is to fix into the structural wall. A shelf loaded with stacked crockery can easily exceed 60kg, so add a third bracket on spans over 1,200mm.
Mount the lowest shelf at least 450mm above the bench so there is working room underneath, and keep the top shelf within reach — anything above 1,800mm becomes a manual handling issue and, in practice, becomes where things go to be forgotten.
Leave a 25–50mm gap between the shelf and the wall on wet-area installations so water can drain and you can clean behind. Sealed-to-wall shelving looks tidier but traps moisture at the joint.
For cleaning, the rule with stainless steel is simple: always work with the grain, never against it. Use a mild detergent and a soft cloth or a non-scratch pad daily. Avoid chlorine bleach in contact with stainless — it is the most common cause of the pitting and brown staining that people mistake for "rusty" stainless. If you must use a chlorine sanitiser, rinse thoroughly with clean water and dry immediately. Never use steel wool or a wire brush, which embed carbon steel particles that then rust and look like the bench itself is failing. Once a month, a proprietary stainless cleaner and polish applied along the grain will restore the finish and add a thin protective film.
Frequently asked questions
What grade of stainless steel is best for commercial kitchen tables?
Use 304 grade (18/10) for all food-contact benches, sinks, and wet areas — its nickel content resists salt, acid, and sanitisers. Grade 430 is 25–35% cheaper but rusts near water and salt, so restrict it to dry non-contact uses such as wall cladding. Specify at least 1.2mm gauge for the top.
How many sinks do I need in a UK commercial kitchen?
Most kitchens need at least three: a dedicated hand wash basin used only for hands, a food preparation sink, and a wash-up sink. Add a separate raw meat or fish sink where cross-contamination risk requires it, and a cleaner's sink outside the food preparation area.
What height should a commercial kitchen work bench be?
The UK standard is 900mm, with adjustable feet giving roughly 850–900mm. Drop to 850mm for heavy tasks needing downward force such as jointing or kneading, and raise to 950mm for fine patisserie work. Keep heights consistent across a kitchen rather than mixing.
Is flat pack stainless furniture strong enough?
Yes, for general preparation. Modern flat pack benches with bolt-through leg sockets and folded box-section tops are rigid, save 25–40% on delivery, and fit through standard doorways. Choose fully welded for wash-up areas, benches carrying heavy fixed machinery, and high-risk rooms needing seam-free surfaces.
How deep should a commercial sink bowl be?
A wash-up bowl should be at least 500 x 400 x 300mm deep so a 1/1 gastronorm pan and a standard sheet tray can be fully submerged. Shallower bowls make it impossible to properly wash the trays used every day, which becomes a hygiene finding rather than an inconvenience.
How do you stop stainless steel worktops rusting?
Avoid chlorine bleach in direct contact, rinse and dry immediately if a chlorine sanitiser is used, and never clean with steel wool or wire brushes, which embed rusting carbon particles. Clean daily with mild detergent along the grain, and use 304 grade rather than 430 anywhere near water or salt.
