An ADA compliant shower will meet certain design criteria that makes the shower accessible for anyone, including those who use a wheelchair. These criteria include: a threshold height that is no more than ½” high above the finished bathroom floor. Otherwise, the curb must be flush with the bathroom floor

ADA shower guidelines are meant to provide information about measurements, materials, and designs that are ideal for the needs of individuals with various disabilities. This includes things like spacing measurements, shower control and spray unit heights, grab bar placement, shower seat strength, threshold requirements, and more.

While tubs and showers aren’t covered by the ADA guidelines, South has recommendations to make them accessible. “Install ADA-standard tubs — they open and fill when you’re inside and seated (called “ walk-in tubs “),” she says. For the shower size, South says, “You want at least 48 inches square, and preferably larger.”
