How to Use This Calculator

Enter Room Width (inches) and Room Depth (inches) as the interior finished dimensions of the restroom.
Set Fixture Count to the number of plumbing fixtures (toilet, sink, urinal) in the space.
Check Clear Floor Space OK — a result of 1 means the room meets minimum clear floor area for wheelchair approach.
Verify 60-inch Turning Radius OK — a value of 1 confirms a wheelchair can execute a full turn inside the room.
Use Grab Bar Length Needed (in) to specify the required grab bar at the toilet (side and rear walls).
Note Max Sink Rim Height (in) — the sink rim must be at or below this height with knee clearance below.
