A shower pan liner is an essential component of a shower that prevents water from damaging the flooring. It serves several important functions:
• It acts as a waterproof membrane, preventing water seepage and damage to underlying surfaces.
• It promotes drainage by providing an even surface for water to run off into the drain.
• It helps keep mold and mildew at bay by minimizing dampness on walls and floors around the shower area.
Overall, it provides protection against costly repair bills due to water damage in your bathroom.
