Kauwm Professional Waterproof Shower Membrane – 323 Sq Ft, 23.6 Mil Thick

Overview

Kauwm's Professional Waterproof Shower Membrane is a robust moisture barrier designed to protect wet spaces during and after tile or stone installations. The roll measures 3.3 ft by 98.5 ft, delivering 323 sq ft of coverage, with a thickness of 23.6 mils (0.6 mm). This substantial foundation helps maintain a dry, stable base under typical bathroom, kitchen, sauna, and other damp environments.

Engineered to resist humidity and repeated exposure to moisture, the membrane maintains flexibility and resists aging, supporting the longevity of surrounding tile and substrate. The polyethylene core adds a trusted level of water resistance compared with standard underlay options, helping to keep subfloors and walls drier over time.

Versatility is a key feature. It can be used behind shower walls and floors, kitchen backsplashes, bathroom walls, and sauna areas. It works with a range of tile types, including marble, cement, ceramic tiles, and stone surfaces, and is suitable for indoor and outdoor installations where a dependable moisture barrier is beneficial.
