Once the silicone has cured you can then fix in place the remaining tiles. Don’t be tempted to tile right down to the tray, leave a 2-3mm gap. Allow the tile adhesive to cure for at least 24 hours to ensure its gone off properly. On first inspection of the walls it was apparent that many of the tiles had come loose also so all of these were also removed. Note: We always recommend that a shower tray is installed before the walls are tiled as this allows for a much more water tight joint as you can then tile down to the tray and seal it correctly. How to install a low level or low profile shower tray With the tiles removed the wall was also inspected closely. Again, long term moisture ingress had caused considerable damage so we also pulled a section of wall away and replaced it.

In general, if you are installing on to a floating timber floor, a flat low profile tray is the way to go as the flat base will provide great support for the tray and also access to the underside of the tray for the waste should be fairly straight forward as you can simply cut a hole in the floor.

The main rule of thumb when it comes to any job such as this is to keep it as simple as possible. Go with most suitable type of tray for the room space you have and go with the most straightforward method of getting the waste water from eth tray to the main drainage point. Unfortunately in some cases, this may mean a compromise in terms of appearance. Before placing the tray down in place, we first replaced the sections of flooring that had been removed that would sit under the shower tray. At the end of the tray we also created a trap door. This was simply a section of flooring that could be easily unscrewed and removed so that we could access the waste. That being said though, if it’s a new install and you have to get a full waste pipe in place to carry water to the main drain, this may be something you can do along with the rest of the work.

Once the tray has set and is fully secured, the waste can now be connected up. In this case we were using the existing waste so we pushed the end of the waste pipe up under the floor (with the screw cap, washer and tapered rubber seal in place) and using a torch, located it within the connection on the tray’s waste trap.
The compression joint screw cap was then tightened pinch tight to secure the waste pipe in place. Advice on plastic compression wastes and how they go together can be seen in our project here. By tiling down to the tray and leave a 2-3mm gap between the tiles and the tray you can fully seal this with silicone and allow for any expansion and contraction as the silicone itself will absorb this and reduce the risks of any leaks. Tighten it so that it is “pinch” tight e.g. tighten it as much as you can by hand and then one final turn to pinch it up and seal it. You don’t need to over tighten it!

Simply drill a 57mm hole in the soil pipe, coat the inside face of the boss with silicone and clip it in place. Once the tile adhesive had cured correctly the battens were removed leaving roughly a 2 inch gap that we could then tile once the ray was fully in place. For further help and advice on ceramic tiling, see our project here. Fitting or installing shower trays can be a DIY job but the utmost care must be taken to ensure that the tray is both fully sealed, waterproof and also totally level on the base it’s sitting on once it’s in place. With someone filling the waste for you, use a torch to inspect the waste trap and all the pipework for any signs of leaks. If there are any tighten any compressions joints as required.Installing or fitting a shower tray is very much dependent on the type of tray you are installing and the surface it’s being installed on.
