A4.23 Bathrooms, Bathing Facilities, and Shower Rooms.

A4.23.3 Clear Floor Space.

Figure A7 shows two possible configurations of a toilet room with a roll-in shower. The specific shower shown is designed to fit exactly within the dimensions of a standard bathtub. Since the shower does not have a lip, the floor space can be used for required maneuvering space. This would permit a toilet room to be smaller than would be permitted with a bathtub and still provide enough floor space to be considered accessible. This design can provide accessibility in facilities where space is at a premium (i.e., hotels and medical care facilities). The alternate roll-in shower (Fig. 57b) also provides sufficient room for the “T-turn” and does not require plumbing to be on more than one wall.

Diagram (a). A 90 inch by 60 inch toilet room with roll-shower is illustrated. A 32 inch wide clear opening is centered in the middle of the long wall opposite the fixtures. On the back wall, measured from the left side wall, the centerline of the toilet is 18 inches. The centerline of the lavatory is 30 inches from the centerline of the toilet. The width of the shower stall is 30 inches measured from the right side wall. The depth of the shower seat is 18 inches measured from the front wall.

Diagram (b). A 60 inch by 93 inch toilet room with roll-in shower is illustrated. A 32 inch wide clear opening is centered in the middle of the long wall. On the side wall, the centerline of the toilet is 18 inches from the back wall, and the centerline of the lavatory is 27 inches from the centerline of the toilet. The shower is on the opposite side wall. The depth of the shower seat is 18 inches measured from the front wall.

Figure 57(b) Roll-in Shower with Folding Seat: An alternate 36 inch minimum by 60 inch (915 mm by 1220 mm) minimum shower stall is illustrated. The width of the stall opening stall shall be a minimum of 36 inches (915 mm) clear located on a long wall at the opposite end of the shower from the controls. The shower seat shall be 24 inches (610 mm) minimum in length by 16 inches (330 mm) minimum in width and may be rectangular in shape. The seat shall be located next to the opening to the shower and adjacent to the end wall containing the shower head and controls. (4.21.2, 9.1.2, A4.23.3)
