The two specifications that matter most when buying stainless steel for a commercial kitchen are the steel grade and the thickness. Grade 304 resists corrosion from salt, acid and constant sanitiser far better than the cheaper grade 430, and a thicker top resists denting. Everything else — bench height, splashback, undershelf, castors — follows from how the piece will actually be used.
📋 What this guide covers
- Grade 304 versus 430, and where each belongs
- Why thickness and bracing matter more than price
- Bench height, depth and splashback decisions
- Shelving, racking and load ratings
- Sinks, drainers and the plumbing detail people forget
- Cleaning stainless steel without wrecking the finish
1. Grade 304 or grade 430
Not all stainless steel is the same, and the difference shows up within a year or two in a working kitchen.
| Grade | Corrosion resistance | Best for |
|---|---|---|
| 304 | High | Benches, sinks, prep surfaces, anywhere exposed to salt, acid, moisture or heavy sanitiser use. |
| 430 | Moderate | Dry areas, splashbacks, panels and non-food-contact surfaces where budget matters. |
Grade 304 contains nickel, which is what gives it the corrosion resistance. Grade 430 does not, which is why it costs less and why it will pit and stain where 304 will not. In a wet, salty kitchen the cheaper option often ends up being the more expensive one.
ℹ️ Ask for the grade in writing
"Stainless steel" on a listing is not a specification. Ask which grade the food-contact surfaces are, and what thickness the top is. A reputable supplier will tell you without hesitation.
2. Thickness and bracing decide how long it stays flat
A thin bench top with poor bracing will bow in the middle within months of taking real weight. Look for a top thick enough not to flex, a folded or channelled edge for rigidity, and cross bracing between the legs.
Adjustable feet are not a luxury. Commercial kitchen floors are rarely level, and a bench that rocks is a bench that spills. Check that the legs have adjustable bullet feet before you buy. Browse stainless steel work benches.
3. Get the height and depth right for the task
Bench height changes how tired your team is at the end of a shift. A standard work bench height suits general prep for most people. Lower it for tasks needing downward force, such as rolling dough or portioning; raise it for detailed work done standing straight, such as plating or decorating.
Depth matters just as much. A deep bench gives room to work but wastes floor space in a narrow kitchen and puts things out of reach against a wall. Measure your walkways first: aisles that are too tight are the most common and most expensive fitout mistake.
🔧 Pro tip, decide the splashback before you order
A bench against a wall almost always wants an upstand or splashback, because the gap between bench and wall is where grease and food collect and where cleaning cloths cannot reach. A bench in the middle of the room wants no upstand at all, so staff can work from both sides. Fixing this after delivery is not possible.
4. Undershelves, cabinets and drawers
Open undershelves are cheap, easy to clean and keep everything visible. Enclosed cabinets keep dust off and look tidier but need cleaning inside and can hide problems. Drawers suit small items and utensils that would otherwise clutter a bench.
The right answer usually depends on what sits underneath: bulk containers and pans on open shelves, clean crockery and packaging in cabinets, and small tools in drawers. Compare over and undershelves, stainless steel kitchen cabinets and stainless steel drawers.
5. Shelving and racking: check the load rating
Shelving is where kitchens quietly overload equipment. Every shelf has a rated capacity per level, and stacked tinned goods or full gastronorm pans get heavy fast.
Work out what will actually go on each shelf before you buy, and check the rating per level rather than the total for the unit. In coolrooms and wet areas, choose a finish designed for it — polymer-coated or dedicated coolroom shelving handles constant moisture better than plain steel. See shelving and racking.
6. Sinks and the plumbing detail
Choose sink bowl size around your largest item, not your average one. A pot that does not fit in the sink becomes a daily problem that no amount of good intention fixes.
Decide which side the drainer goes on based on how your staff move, and confirm the waste position lines up with your existing plumbing before you order. Repositioning a floor waste is a much bigger job than buying the right sink first time. Browse sinks and sink benches.
ℹ️ Mobile beats fixed more often than people think
Benches and shelving on lockable castors let you clean underneath properly and reconfigure a kitchen as the menu changes. If the piece does not need to be plumbed or hard-wired, consider a mobile version. See trolleys and transport.
7. Cleaning stainless steel properly
Stainless steel resists corrosion because of a thin passive layer on its surface. Damage that layer and the steel underneath will rust.
Clean with warm water, a mild detergent and a soft cloth, always working in the direction of the grain. Avoid steel wool, abrasive pads and chlorine bleach left sitting on the surface — those are what cause the rust spots people blame on "cheap steel". Rinse and dry after sanitising rather than letting product dry on. Compare the full stainless steel and storage range.
Final thoughts
Stainless steel is the one part of a fitout you should expect to still be using in ten years. Specify grade 304 for anything wet or food contact, insist on a top thick enough not to flex, decide the splashback and undershelf configuration before you order, and check shelving load ratings against what will genuinely sit on them. Buy it properly once.
Frequently Asked Questions
Grade 304 for benches, sinks and any food-contact or wet surface, because it resists corrosion from salt, acid and sanitisers. Grade 430 costs less and is acceptable for dry areas, splashback panels and non-food-contact surfaces, but it will pit and stain where 304 will not.
If the bench sits against a wall, yes. The gap between bench and wall traps grease and food and cannot be cleaned properly. If the bench is in the middle of the room and staff work from both sides, order it flat with no upstand. Decide before ordering, because it cannot be added later.
Usually damage to the surface layer rather than poor steel. Steel wool and abrasive pads scratch through it, and chlorine bleach left sitting on the surface attacks it. Clean with mild detergent and a soft cloth along the grain, then rinse and dry. A lower grade such as 430 in a wet area will also corrode.
Work out what will sit on each level, then check the rated capacity per shelf rather than the total for the unit. Full gastronorm pans and tinned goods get heavy quickly. In coolrooms and wet areas, choose a finish made for constant moisture rather than plain steel.
If the bench does not need plumbing or a hard-wired connection, lockable castors are usually the better choice. They let staff clean underneath properly and let you reconfigure the kitchen as the menu changes. Fixed benches with adjustable feet suit sink runs and anything plumbed in.
