Wetroom Tanking

Frequently Asked Questions:

1. What is wet room tanking?

Wet room tanking is the process of waterproofing floors and walls in a wet room using specialist membranes, sealants, and coatings. It creates a watertight barrier to stop water leaking into the structure of your home.

2. Why is tanking important in a wet room?

Unlike standard bathrooms, wet rooms don’t rely on a tray to contain water. Tanking ensures water can’t seep into floors or walls, preventing leaks, damp, and long-term damage.

3. What products are used for tanking?

• Liquid waterproof membranes (paint-on sealants)

• Self-adhesive waterproofing membranes

• Sealing tapes for corners and joints

• Waterproof backer boards under tiles

Often, a wet room tanking kit includes everything needed.

4. Is wet room tanking difficult to install?

Not necessarily. Many kits are designed for easy DIY application, with brush-on or roll-on membranes and pre-formed tapes. However, correct preparation and coverage are vital, so many people prefer professional installation for peace of mind.

5. How long does wet room tanking last?

When installed correctly, tanking is long-lasting and permanent, designed to provide waterproof protection for the lifetime of the wet room. It should always be applied before tiling or fitting flooring.
