Bathing rooms: showers, tubs and transfer spaces

Chapter 6: Plumbing Elements and Facilities Bathing Rooms Controls at Bathtubs and Shower Compartments [§607.5, §608.5] Controls and faucets at showers and bathtubs must be usable with one hand and not require tight grasping, pinching, or twisting of the wrist, or more than 5 pounds of force (lbf) to operate. Their location is specified so that they are within accessible reach range while not obstructing grab bars and are usable from outside transfer shower compartments and bathtubs. Shower Spray Units and Water Temperature at Bathtubs and Shower Com- partments [§607.6, §608.6] A hand-held shower spray unit that can also be used in a fixed position is required at all accessible showers and bathtubs. The required on/off control for the hand-held unit must have a “non-positive shut-off” which does not fully stop the flow of water but allows it to be reduced. It also prevents cross-connections and other hazards prohibited by plumbing codes. The water temperature is limited to 120°F. The hand-held unit needs to be reachable within a height of 48” above the shower floor, measured to the operable portion. Vertical bars with adjustable heights offer more options for using it in a fixed position and are permitted, but they also may result in the hand-held unit being out of reach unless it is returned to a lower position. Vertical bars cannot obstruct use of grab bars and must be at least 1½” above the top gripping surface. An additional fixed shower head can be provided at any height Hose at least 59” long Usable as both a hand-held shower and fixed-position shower head Faucet controls, diverter valves, and other controls must comply as An on/off control with a non- operable parts positive shut-off is required A fixed shower head at 48” maximum above the shower floor can substitute for a hand- held shower spray unit at shower compartments (not bathtubs) in facilities not serving as medical or long-term care facilities, transient lodging, or dwelling units. 16
