How do I get this shelf off my wall, no screws showing
Many fixtures with hidden brackets - especially bathroom fixtures - are secured with a set screw into each bracket. Check the underside on each end of the shelf for a small screw. These are usually slotted or hex screws, usually no more than 1/2" in length. You may need to back the screw out almost all the way, as there is sometimes a lip it has to clear.
