A shelving system can include adjustable shelves. The shelves can be adjustable in both the horizontal and vertical directions. The shower organizer can have a hinged clamp which can include a tapered gasket configured to secure the shelving system to a shower head pipe. The shelving system can be further fitted with a suction cup attached to its lower end to further secure the organizer to a wall. The suction cup can be rotatably mounted to the lower end of the shower organizer so that the position of the suction cup may be adjusted such that the suction cup is positioned over a flat surface.
