The timeless beauty of ceramic and stone tiles enhances the aesthetics of any bathroom. Tiled showers, steam showers, and bathtub surrounds are luxurious and elegant and add to the value of your home.

Tiles are not inherently waterproof, however, and must be installed in conjunction with a waterproofing system that effectively manages moisture to protect moisture-sensitive building materials and control mold growth.

Assemblies achieved using the Schluter®-Shower System reduce total installation time and eliminate the risk of failures due to water and vapor penetration, thus preventing efflorescence and mold growth.

Many components come into play when building a watertight and waterproof tiled shower. Schluter® offers you various options that will help you save on installation time, while accommodating your taste and needs.
