This disclosure relates to a grab bar assembly that includes a bar extending along a longitudinal direction. The bar includes opposing legs extending away from a front side to a rear side and terminating in a base. The base provides a surface that seals against a wall. The bar is a non-reinforced structure having no internal metallic reinforcing members. In one example, the bar is constructed from a gas-assisted injection molding process that creates a hollow within the bar. The bar includes a gripping area on the rear side, and is over-molded with a thermo plastic elastomer in one example. A single attachment feature, such as a lag screw, is provided at each of the opposing legs to secure the grab bar to the wall. An aesthetic cover is secured to the bar to enclose the fastening element.
