The Homeowner's Guide to 100% Waterproof Showers

The Problem

Most homeowners in London think that tile and grout are waterproof. They aren't. Grout is porous, and over time, water will get behind your tiles. If your contractor used old-school drywall or "green board," you are looking at a mold disaster in 5–10 years.

Section 1: What is the Schluter-Kerdi System?

Schluter is the "Orange System" you see on professional job sites. It uses a polyethylene membrane (Kerdi) that is applied directly to the walls.

The Benefit: It creates a sealed "tank" in your bathroom. Water cannot escape.

The Floor: We use Ditra-Heat for all our London bathroom renos. Not only does it make your floors warm, but it also prevents your tiles from cracking.

Section 2: Why We Also Use Wedi Systems

Wedi is the "Blue Board" system. While Schluter is a membrane, Wedi is the board itself. It’s made of a waterproof foam core that is 100% waterproof all the way through.

Speed & Precision: We can build perfectly straight walls and custom niches faster.

Curbless Showers: Perfect for modern walk-in shower designs.

Section 3: The "Certified" Difference & Warranties

To get the Schluter Lifetime Warranty or the Wedi 20-Year PRO Warranty, the installer must be certified and use approved materials.

As a Certified Installer, we provide a full warranty-backed system that protects your investment.

Your bathroom is the most expensive room to fix if done wrong. Don’t risk it.
