About this detail

An accessible wall-hung urinal installation requires a maximum rim height of seventeen inches above the finished floor and hand-operated or automatic controls positioned at a maximum of forty-four inches above the finished floor. The adjacent urinal partition provides a minimum depth of thirteen and one-half inches from the outer face of the urinal rim to the back of the fixture. An accessible lavatory or sink installation features a thirty-inch by forty-eight-inch clear floor space for a forward approach with insulated water supply and drain pipes underneath to protect against contact. Knee clearance beneath the sink transitions from a minimum of twenty-seven inches at an eight-inch depth to a minimum of twenty-nine inches at the front edge, maintaining a nine-inch minimum toe clearance height.
