What Is a Shower Pan Liner?
A shower pan liner is a flexible waterproof membrane installed over a properly pre-sloped shower base and mechanically clamped into a compatible drain assembly. The liner creates a continuous waterproof layer beneath the mortar bed, helping manage water that passes through grout joints and tile. Proper installation of a PVC pan liner supports long-term system performance in conventional shower assemblies.
