List of featured suppliers of SHOWER UNDERLAYS on Building Products Index
A shower underlay is a waterproof layer that is placed beneath the tile or other surface material in a shower. It is installed to prevent water from seeping through the shower floor and causing damage to the underlying structure. The underlay is typically made from a flexible, synthetic material and is cut to fit the floor of the shower stall. Once installed, the underlay provides a barrier that directs water to the drain and ensures that the shower remains leak-free.
