Perfect if you're short on shelf space and need a smaller shelf to better maximize your space, this corner caddy is compact in size taking up minimal room in the shower than a traditional tiered shower organizer. With no tools required to install, simply press the sturdy back suction cups against a non-porous surface such as glass, and some metals to set it up. The powerful adhesive of the suction cups keep it from shifting out of place. And a thick vinyl coating protects the caddy from corrision and rust, so you can enjoy it for years and years.
