ADA Bathroom Requirements

The basic ADA guidelines for a single-user restroom are:

  • 30-inch by 48-inch access to the sink (the door can’t swing into this rectangle). The measurement starts from the point where a person has 9-inch vertical clearance for their feet and 27-inch vertical clearance for their knees.
  • The center line of the toilet must be between 16 and 18 inches from the side wall.
  • A clear circle of at least 60 inches around the side wall and 56 inches from the rear wall to allow a wheelchair to turn (the door cannot swing into the minimum required area for wheelchair-accessible toilet compartments).
  • A toilet seat height of 17-19 inches
  • Faucets should be lever-operated, push, touch, or electronically controlled. They should be usable with one hand without the need to tightly grasp, pinch, or twist the wrist. Users shouldn’t have to exert more than 5 pounds of force to use the faucet to meet ADA requirements.
  • To meet ADA guidelines, sinks shouldn’t be mounted higher than 34 inches from the floor, and they should have a knee clearance of 27 inches high, 30 inches wide, and 11 to 25 inches deep. You also need a clear floor space and insulated pipes under the sink.
  • ADA compliant urinals should be stall-type or wall-hung at a maximum of 17 inches from the floor.
  • Water closets must be 17 to 19 inches from the floor (measured from the floor to the top of the toilet seat). Like faucets, flush valves shouldn’t require tight grasping, pinching, or twisting of the wrist.
  • Grab bars should be at least 36 inches long on the rear wall or 42 inches on the side wall and should be mounted 33-36 inches above the floor. They need a gripping surface of at least 1.25 inches, mounted at least 1.5 inches from the wall. They should be able to withstand at least 250 pounds of pressure.
