A Schluter®-KERDI system is a complete waterproofing system designed for tiled showers and other wet areas. Instead of relying on tile and grout to keep water out, it creates a waterproof barrier behind the tile using compatible membranes, drains, accessories, and installation methods.

If your project includes a shower or other wet area, a complete waterproofing system offers the highest level of long-term protection. While there are several excellent waterproofing systems available, using components designed to work together helps reduce weak points, simplifies installation, and improves durability.

No. Tile itself is water-resistant, but grout and many tile assemblies allow moisture to pass through. Without a waterproof layer behind the tile, water can eventually reach drywall, framing, or subfloors, leading to mold, rot, and expensive repairs.

Not at all. Schluter systems are used in everything from standard family bathrooms to high-end custom showers. They can be installed in walk-in showers, tub surrounds, bathroom floors, laundry rooms, and other wet areas where long-term moisture protection is important.

Yes. Several manufacturers produce excellent waterproofing systems. Schluter is simply one of the best-known and most widely used because of its comprehensive product lineup, proven performance, and integrated approach. The most important factor isn't the logo on the box—it's using a complete, properly installed system rather than mixing incompatible products or relying on outdated methods.
