Just be really careful. I'm in a chair, when I was falling before the chair, hauling my 100 lbs up from floor using the permanent grab bars that DH (the ex-carpenter) put in wood or reinforced walls, would probably pull suction cups off, especially since I was pulling from downwards off floor. For holding steady in shower, sounds good, for serious hauling up, think twice. Also on a tiled wall, might slide, hit a grout line and suction would be broken. They might be OK until they really aren't. Please be careful!!!!
