Preparing the Wet RoomFirstly clear the room that you are going to be installing/building the wet rooms area into, simple reason when it’s clear it’s easy to measure and identify exactly what you want to do.
Floor PreparationTiling directly on to floor boards is a no no, you need a solid flat fixed surface to ensure that there is no movement under the tiles, we would recommend using a tile backer board, by installing tile backer board it also gives a waterproof area to butt up to your wet room area and is super quick to install, you will also gain insulated properties within the room. Utilising a decoupling membrane can also be very useful and can stop movement which in turn stop tiles from coming up and grout cracking.
Wall PreparationWe would always recommend removing any plaster board within the wet rooms area, primarily because it’s porous. Again tile backer board can be used on stud wall and also brick walls, utilising tile backer board will not only give you waterproof walls once tanked, but also increase the insulation properties of the room, especially if you are installing on to an outside wall. You can utilise different thicknesses of backer board which will give you difference thermal properties. Install these board is very simple you either utilise Disc’s dowels which are drilled and then hammered in to concrete walls or Washers and screw them to the stud work, both options spread the load of the fixing.
Choosing which wet rooms tray should be installedMost wetroom trays on the market are a foam based core with reinforced meshing on the surface, all foam decks can be installed on both concrete floor and timber floors, however on timber floors under boarding support is required, in most installation installers want a flush finish with the floor boards and tile backer boards so noggins will be required on the joists and ply to be dropped down on these to give flush support with the tray. Foam core wet rooms can be installed directly in the screed or concrete floors as they are fully supported. Alternatively if you don’t want to under board you wet room areas you can utilise a GRP Deck (Glass Reinforced Plastic) these decks come with pre formed falls and are incredibly strong and do not require under boarding.
