Line drawing showing side view/section of two bathtubs (a and b) - one equipped with a seat in the tub and the other with a built-in seat at the head (rear) of the tub. Drawings show the location of grab bars, control area and the hand-held shower.
(a) Seat in Tub. At the foot of the tub, the control area is shown by a dashed line in the shape of a box located below the grab bar and offset toward the open side of the tub. The grab bar above the control area is at least 24" long starting at the front edge of the tub. It is mounted 33 to 36 inches off the floor. At the back wall, there are two grab bars, one mounted directly over the other, both a minimum of 24" long. Each starts no more than 12 inches from the corner at the foot of the tub. The top bar is mounted at 33 to 36 inches off the floor. The bottom bar is mounted 9 inches above the rim of the tub. At the head of the tub, there is one grab bar at least 12 inches long. The bar starts at the open side of the tub and is mounted 33 to 36 inches off the floor. This view also shows a seat installed in the tub.
(b) Seat at Head of Tub. The drawing for the foot of the tub is the same as (a) above. The drawing for the back is the same as above except that the two grab bars are 48 inches minimum length and the bars must end no more than 15 inches from the head wall. This drawing shows a seat area at the head of the tub, no more than 15 inches deep.
