If you’re installing tile in showers or wet areas, using a Schluter waterproofing system is one of the most reliable ways to prevent failures and costly callbacks.
Water doesn’t forgive shortcuts.
If you’re building showers or wet areas, your waterproofing system matters more than anything you’ll install on top of it. A failed system doesn’t just cost time: it costs callbacks, reputation, and profit.
That’s why more contractors are switching to a Schluter waterproofing system: because it’s built to eliminate guesswork and perform long-term.
Why Contractors Use a Schluter Waterproofing System
This is why more contractors are choosing a Schluter waterproofing system for long-term performance and fewer callbacks.
Every component is designed to work together:
- Membrane
- Drain
- Substrate
- Trim
Building with a Schluter waterproofing system helps ensure your installs last and your reputation stays solid.
One manufacturer. One warranty. One system you don’t have to troubleshoot on site.

- No secondary sealing
KERDI-LINE is ideal for:
- Curbless showers
