Product Description:

The Schluter® KERS20R Kerdi Right Side Corner 20mm is a factory-fabricated waterproofing corner designed to provide a fast, reliable, and professional solution for sealing critical right-side inside corners in curbless shower installations. Made from genuine Schluter® KERDI waterproofing membrane, this preformed corner eliminates the need to fold or cut membrane in difficult areas, reducing installation time while ensuring a consistent, watertight finish.

Specifically engineered for 20mm-thick assemblies, the KERS20R is ideal for use where the shower floor meets the wall on the right side of the installation. Its seamless construction minimizes membrane buildup at the corner, creating a smoother substrate for tile installation and helping maintain a clean, professional appearance. By eliminating overlapping layers typically created with field-cut membrane, the KERS20R makes it easier to achieve flat tile surfaces and precise corner detailing.

The KERS20R integrates seamlessly with the Schluter® KERDI Shower System, including KERDI-LINE linear drains, KERDI waterproofing membranes, KERDI-BAND, and other Schluter waterproofing accessories. When installed with unmodified thin-set mortar according to Schluter installation guidelines, it forms a dependable waterproof seal that helps prevent water penetration into wall cavities and subfloors, protecting the structure from moisture damage, mold, and mildew.

Designed for both residential and commercial tile installations, the Schluter KERS20R is an excellent choice for walk-in showers, barrier-free showers, wet rooms, and other tiled wet areas where dependable waterproofing is essential. Its factory-made design ensures consistent quality and accuracy, reducing installation errors and providing installers with a dependable solution for challenging inside corners.

Whether you're building a new shower or renovating an existing bathroom, the Schluter KERS20R Kerdi Right Side Corner 20mm offers long-lasting waterproof protection, simplified installation, and the trusted performance that professionals expect from the Schluter Shower System. It helps create a durable, leak-resistant tiled shower assembly while delivering a cleaner installation and lasting peace of mind.
