Waterproofing
What keeps the water in.

Tiles and grout aren't waterproof on their own. Behind them, a waterproof layer protects the walls and floor in every wet area.

The basics

Showers, wet rooms and the walls around baths are tanked before tiling. It's the part you never see, and it matters most.
