When determining the length of a grab bar needed, keep in mind that the overall length of the grab bar is about 3 inches longer (3.125 - 3.25 inches depending on the style of bar) than the name of the bar. So a 12 inch grab bar would measure about 15 inches end to end.
12 inch grab bars are perfect in places where just a small handle is needed. These bars are frequently installed vertically at the entrance to showers and tubs where bathers are likely to lose their footing. While installation into studs is always ideal, state of the art Snaptoggles and Secure Mount anchors can make any installaltion easy even if you can't locate the studs. All of our 12 inch grab bars meet or exceed ADA guidelines for safety in the bathroom.
