ADA-Compliant Kitchen Sinks: What Importers Need to Check
Accessible kitchen specifications create a requirement that reaches all the way back to the press die: bowl depth. Importers who sell into public housing, care facilities, hospitality projects or any development that has to meet accessibility rules will eventually be asked for a sink that complies, and the answer is rarely in the existing catalogue.

What an accessible kitchen sink specification usually contains
- Bowl depth. Sinks in accessible kitchens are commonly limited to a maximum bowl depth of about 6.5 inches, or 165 mm. This is the single number that decides whether an existing model can be used at all.
- Counter height. Sink counters are generally set at a maximum of 34 inches, or 865 mm, above the finished floor.
- Knee and toe clearance. Where a forward approach is required, the space under the sink has to provide clearance for a wheelchair, typically 27 inches high, 30 inches wide and 11 inches deep.
- Insulated pipes. Supply and drain pipes under the sink must be insulated or otherwise protected against contact.
- Reach and controls. The faucet and any controls must be operable from a seated position, which in practice pushes the faucet toward the front of the deck.
Accessibility rules differ between jurisdictions and between project types. In the United States, public buildings follow the ADA Standards, while residential accessibility is often specified through ANSI A117.1 or fair housing guidance. Confirm the exact reference with the specifying architect before you place an order, because the bowl depth limit is not always identical.
Why bowl depth is the factory-side problem
A conventional stainless steel sink is 180 to 220 mm deep, which is well beyond the accessible limit. Reducing depth is not a matter of ordering the same sink shallower: drawing a bowl to a different depth changes the material flow over the die, so the factory needs either an existing die in the correct depth or new tooling. In handmade production, the depth is set by the sheet width and the welding jig, so a shallower bowl is usually more straightforward - which is why accessible projects are often supplied from the handmade range even when the rest of the kitchen uses pressed sinks.
What to specify on the order
- Mounting style, because the cut-out and support method are part of the accessibility solution.
- Maximum bowl depth, stated in millimetres and inches.
- Drain position, checked against the knee clearance zone.
- Whether the drain assembly and insulation are supplied with the sink or by the contractor.
- The project reference document, so the factory knows which rule set applies.
How to verify before shipping
Measure the finished bowl depth with a steel rule at the centre of the bowl rather than at the edge, and record it with photographs against the order. Confirm the drain position on the same drawing, and check that the drain hardware supplied does not reduce the usable depth below the limit. If the sink will be installed over a knee space, confirm the overall depth including the drain trap is still within the allowance.
If you have an accessible project that needs a specific bowl depth, send the requirement to TEGAO with the target quantity and destination market, and the factory will confirm whether the depth is available from existing tooling or what a new tool would require - contact page. General sizes are covered in the market size comparison, and product by product in single bowl sink dimensions.
