Chapter 6: Plumbing Elements and Facilities Toilet Rooms
Grab bars and wall or other surfaces adjacent to them must be free of abrasive or sharp
elements. Any projecting object must be located at least 12” above grab bars and at least 1½”
from the bottom and ends of grab bars so that the reach and use of grab bars is not impeded.

Grab bars can have circular or non-circular cross-sections but must have rounded edges. The
1½” clearance between the grab bar and wall is not a minimum but an absolute dimension to
prevent entrapment. Grab bars cannot rotate within fittings. The structural strength of grab
bars must withstand a vertical or horizontal force of 250 lbs. at any point on the grab bar,
fastener, mounting device, or supporting structure.
