The ADA has specific rules for accessible bathroom fixtures, including vanity sinks. The height a sink can be mounted to is key, and you’ll want to ensure there’s enough knee space under the counter for a wheelchair user to roll under without running into pipes or cabinets.

Fortunately, there are more options than ever for ADA-compliant sinks that don’t look institutional or dated. You can find ADA floating vanities that keep the pipes hidden behind the face, and you can also use table style vanities that have legs and don’t include cabinet doors for a more traditional look that meets ADA standards.

ADA Residential Bathroom Requirements: Designing Accessible Homes

To comply with the ADA, you’ll need a clear unobstructed roll under area that’s at least 34 inches wide and 30 to 48 inches deep underneath the sink. This area should be free of any obstructions that can interfere with a person in a wheelchair’s ability to move under the sink and it must be free of any doors, walls or partitions that could prevent a wheelchair from rolling through the open space beneath the sink. In addition, sinks should not be more than 34 inches high to ensure adequate front approach clearance and sink controls must be operable with one hand and not require tight grasping or twisting of the wrist with five or fewer pounds of force.

Another important ADA requirement is that sinks must have a rear drain to allow for the shortest possible distance from the floor to the bottom of the overhanging sink cabinet. And all ADA compliant restrooms must have either wall-mounted or stall type urinals with a maximum rim height of 17 inches. The urinals must be mounted at a minimum of 14 inches from the floor, and clear space of 30 inches wide by 48 inches deep must be reserved for a wheelchair to maneuver around them.
