Installing a wetroom is a simple process, you are building up a series of comprehensive barriers which reinforce each other - the only additional tasks to tiling are preparing the room with a primer, sealing all joints with sealing tape and then applying the tanking membrane, which is simply rolled on to the floor and walls. It gives your bathroom a failsafe protection against leaking, unlike a standard bathroom which has no protection. There are also now pre-formed trays available to sit under the floor, which you then tank over – these create a slope towards the drain, making the installation process even more straightforward. This simple to follow step-by-step guide illustrates the steps involved...

There are several ways of constructing a wetroom, but each have some basic principles that must be observed;
The Roman Shield Pre-formed Shower Floor can be installed directly to joists without additional support, or to a concrete floor.
The Pre-formed Shower Floor can be trimmed if necessary and is screw fixed to the joists. WBP/Plywood can then be used to complete the level shower room.
Ensure all surfaces in the construction area are dry, solid, supportive and level, as well as free from oil, grease, dust and other separating layers.
The floor area of the room should be primed with a turn up of 100mm onto the wall.
The walls should also be primed floor to ceiling in the showering area and in the splash zone of the shower, normally 100mm past the showering area. Leave the primer to cure.
Apply the outlet sleeve; this is usually self-adhesive. Ensuring it is flat with no raised edges, creases or bubbles. The centre of the outlet sleeve is then removed and the waste traps clamping ring is fixed into position.
The tanking tape and pipe-sleeves are bedded down using the tanking compound. All wall to wall and wall to floor junctions as well as butt joints and nail or screw heads must be reinforced with the tanking tape. The compound is applied using a medium size paint brush.
Ensure the tape, pipe-sleeves and outlet sleeve have been fitted to the appropriate areas and wait until the tanking compound is dry.
The entire floor area of the room should be tanked with a turn up of 100mm onto the walls. The walls should also be tanked floor to ceiling in the showering area and in the splash zone of the shower, normally 100mm past the showering area. The recommended finishing thickness is 1mm which can usually be achieved in 2 or 3 coats.
You are now ready to start tiling and grouting as normal.
*These steps are based on those involved when using Roman Shield tanking materials and can vary from manufacturer to manufacturer.
Once all these steps have been completed you can then finish the room to your own design. For the ultimate in indulgence, and a top end project, complete the look with a 10mm thick wetroom panel and add a multi-function shower valve with the option of a drencher head, multi-mode hand shower and body-jets.
