Review (1/5): Dont bother
The quickest waste of money I have ever spent on just about anything. Instead of purchasing this, wet down 20 $1 bills and mold them into the rough shape of this footrest. Then stick the wad of wet-paper to the wall of your shower - TA DA - you already have something that sticks to the wall better than this plastic number. We have clean, non-porous walls (single sheets of acrylic) and this "step" (and I use that word lightly) still slid down, at one point all on its own with no weight put on it. If you are willing to glue this to a wall, you may actually have a chance at using it - otherwise: save your money.
