When planning your wet room or walk in shower it is extremely important to carefully plan and install the flooring to avoid any dangerous and costly problems in the future. Each part of wet room flooring from the waterproofing to the tiles is extremely important, and in this blog we’ll take you through the things you need to consider before installing wet room flooring, as well as installation options.
Things to consider before installing wet room flooring:
- Construction of the substrate
- The placement of the shower tray
- The size of the shower tray
- If electric underfloor heating will be added
- Which waterproofing method you will use
Wet room flooring installation methods will depend on your substrate and choice of waterproofing methods. If you are tiling over timber it is important that the boards are rigid enough to cope with the weight of boards, tiles and foot traffic. Check the individual installation guidelines for your chosen waterproofing method to check it is suitable for your substrate.
Once the shower tray is installed and the walls have been waterproofed you can begin waterproofing the floor. If you are not including electric underfloor heating the best option for waterproofing is using tile backer boards such as those from Orbry or Marmox. As well as waterproofing, tile backer boards can be used to raise the height of the floor by 10mm to sit flush with a walk-in shower tray.
If you are planning on installing electric underfloor heating a waterproof uncoupling membrane is a better option than tile backer boards for your wet room flooring. This is thinner and therefore will not raise the overall height of the floor more than the shower tray. The decoupling membrane will stop any movement in the substrate effecting the tiles above, as well as creating an insulated layer beneath the electric underfloor heating to project the heat upwards.
Once the entire wet room is watertight you can begin tiling. As a wet room contains a level access shower, water is more likely to splash throughout the room. This can create a slippery surface, therefore we would recommend using non-slip mosaic tiles to avoid any falls.
