The added safety a grab bar comes with often has a price: specifically your bathroom tiles. The Moen Secure Mount Grab Bars and Mounts, featuring an 18" stainless steel grab bar, uses novel mounting set-up to support greater weight loads without pulling screws or busting tiles and backing. No need to locate on studs. Can support people of up to 300 lbs. when the grab bar and wall mount are used together according to installation directions.
