Barrier Free Guidelines
FULLY RECESSED WASHROOM ACCESSORIES. Recommended wherever possible. It is recommended that all floor-standing and surface-mounted units projecting more than 4" (100mm) from the wall be located in corners, alcoves, or between other protruding structural elements so as not to be a hazard to blind people or interfere with required access aisles and 60" (1525mm) minimum diameter turning spaces for wheelchairs. Surface-mounted units should not be located above grab bars.
