Yes, Bridge Medical Portable Grab Bars will hold securely to most smooth, flat non-porous tiles. The hold will sometimes diminish on natural stone and porous tiles. Please note: The Suction Cups must not overlap with grout lines and the minimum tile size is 5 inches for our BC201, BC500 and BC400 models. The minimum tile size is 4” for our BC600 models. Caution: You should always verify that the tiles you are attaching to are firmly attached to the wall board and not loose or in disrepair.
