The suction works best on ceramic tile, glass, metal, and wood. NO TOOLS REQUIRED: The suction cup is easy to install as it does not require any tools. It does not damage your walls because you do not have to drill holes to install. DRAINING: The open wire design is self-draining to prevent water build up, so your sponge dries faster.
