According to ADA accessibility guidelines, ADA-compliant kitchen sinks must sit no higher than 34 inches above the floor and have shallow bowls between 5 and 6-1/2 inches deep. Sink drains are located at the rear instead of the middle. Knee clearance underneath the sink is a minimum of 27 inches high, 30 inches wide and 19 inches deep, and exposed hot water pipes should be well insulated to prevent burns.
People with mobility or other disability challenges should be able to comfortably wash dishes and enjoy general kitchen sink usage without discomfort. Faucets, drains and back sink areas should be within easy arm reach without causing excess strain on the back, neck or shoulders. Choose a faucet design with a single lever or loop that is easy to operate. ADA-compliant sinks are made in single and double bowl designs and have the same durability as regular sinks.
When customizing kitchen counters for easier access for those with disabilities, keep in mind that the average wheelchair armrest height is 29 inches. Custom kitchen countertops are most comfortable at heights between 28 and 32 inches, although 34 inches is acceptable. An option for homes with disabled and non-disabled persons is to include counters at different heights to accommodate everyone.
