This is a hot topic as many wet rooms are tiled incorrectly, which leads to unwanted leaks and client disappointment to say the least. The cost of remedial action is high because it usually means that the entire installation is suspect and may need to be completely un-installed and reinstalled. That means that the installation costs can be roughly three times the original estimate, never mind the knock-on effect of the installation schedule for the builder or contractor and possible complaints to the architect who is blameless.
Why Tiling Is Done Incorrectly
Wet room installation is something of a specialist skill. While there is no rocket science involved, it does require an appreciation of what must be done correctly and also what can go wrong, which is often picked up through experience. Therefore, the most common cause of tiling issues in wet rooms is simply inexperience on the part of the installer.
Types Of Tile That Are Suitable
A beautiful tiled finish will always be the perfect choice for any wet room – both walls and floor. However, the tile selection must be compatible with the drainage style selected. For example, mosaic tiling is very popular and works perfectly well with conventional square ‘middle of the floor’ drainage. When using a linear drain, more thought has to be made in terms of what drain finishes are compatible with the fragile tile edges and grout.
Things You Must Do
The ‘Must Do’ category is all about preparation and using the correct tanking membrane and adhesive, and the application of these products.
Wet room floors required a 100% bed of adhesive. Dabs at tile corners and centres will allow water to ingress beneath the tiles and will eventually cause problems even with the best tanking systems.
Match the type of tile to the type of user – use slip proof tile if people with reduced mobility, or elderly people, will be using the wet room.
Minimise tile cuts by careful placement of drainage grills – ideally plan the locations in advance so that they match well with the size and type of tile that has been selected.
Ensure no tile or other wet room component can penetrate the waterproofing membrane to avoid leaks.
The Tile Association Standard (BS5385) is a good source of advice on tiling wet locations.
Our installation teams are trained in Denmark by the suppliers to ensure that every aspect of wet room installation is carried out to the highest professional standards. Our technical support team are on hand to provide advice and support throughout all installations.
