Step by step guide to installing your wet room:

1. Disable the water feed to your bathroom before you start ripping it out. Then clean the whole area free of debris.

2. Place the shower tray in its place and start putting boards on the floor and cutting them to size. Once this is done, mark out the area around the tray and then remove all.

3. Take the floorboards where the tray is to be place, making sure you have remove them to the centre line of the nearest floor joist.

4. Work out where the drain will be placed.

5. Build a platform and add a plywood base which needs to be below the surface of the floor joist.

6. Install drain and trap and then connect to the waterpipe making sure it's all lined up.

7. If you need to cut excess floorboards to get to the nearest floor joist, you can fill the void with off cuts or use marine plywood.

8. Apply a 3mm layer of rapid set adhesive with a trowel, fit your shower tray in your new platform, it should fit tightly in the area, make sure it's level by using a spirit level then put some silicone at the edge of tray.

9. Place the drain and trap in place -before the adhesive set- with the tools provided.

10. Put the tilebacker board by laying 3mm adhesive to the area. Check the boards are level and leave adhesive to dry for 2 hours. On wooden floorboards, use galvanised screws and washers to secure them in place.

11. All the holes should be filled with the tanking liquid.

12. Tape all the joined boards with mesh tape.

13. Tile the walls and floors using waterproof adhesive and grout. Lay the tile from the drain area first, make sure that you don't use mosaic tiles smaller than 20mm in bare foot area of your shower.

14. Add a shower screen if you like.
