A great alternative to installing-and the accompanying expense and hassle-safety grips. These are good looking and solid. Note that the manufacturer specifies that they are not designed to support 100% body weight. They are meant to provide some stability and they are great for that. Also note that they work by way of suction so if you have small tile or mosaics in your shower, they might not provide a firm seal. We have 8"X8" marble tiles so there is plenty of smooth surface without grout lines to provide a great vacuum seal.
