Tips for placing shower grab bars include installing a vertical bar on the outside of the enclosure to assist the user as he moves in and out of the fixture. Mount a second bar horizontally, 36 to 38 inches above the floor on the back shower wall.
For greatest security, locate the bars so that they attach directly to a stud behind the wall. If it is not possible to make a stud attachment, use anchors rated for supporting the weight of the bar and the individual who uses it.
In many homes, the bathroom includes a bathtub and shower combination. With this arrangement, place a grab bar at an angle on the back of the tub. At its lowest point, this bar should be 6 to 10 inches above the tub wall. Use a 24-inch bar for studs with a 16-inch spacing to provide the correct angle. The angle allows the user to grab the bar to lower himself into the tub and to raise his body back to a standing position.
Adding a shower chair or stool to the tub makes bathing easier for users with mobility problems. For use with a shower chair, locate the bar about 18 inches above the tub wall.
