Installing Shower trays

• Always check the tray for colour, size and general acceptability before installation. Manufacturers will not accept claims for any of these once the product has been installed.

• Always fit the shower tray before tiling and temporarily fit the waste outlet pipework and trap to the tray

• Position the tray to the walls and rebate the 'upstands' if applicable (see below) and tray walls into the plaster as required.

• Adjust the feet height to give the required clearance. If you are using a tray that does not have adjustable feet you will need to bed the floor to a firm base

• Always bed the shower tray on to a flat, even floor. It is essential that the shower tray base is fully supported, using either:- A silicone sealant, sand and cement -in a 5 to 1 mix, or tile grout adhesive.

• Always coat the whole base area of the shower tray when sticking it down, using silicone sealant, sand and cement or grout adhesive. Spotting the centre and four corners is not a correct or acceptable installation procedure

• If it is necessary to raise the shower tray to accommodate the trap and waste pipe, construct a plinth, using timbers (75 x 1OOmm), with no more than 300mm centres between each timber. Finish with marine plywood base board 20mm thick.

• If a plinth is constructed always bed the shower tray to a plywood base board as you would to the floor using one of the materials already described

• Always make sure the shower tray is level along top edges. This is essential if built-in fall is to allow the water drainage to the waste corner.

• It is important that the tray is level in all directions, place a spirit level on the top edges of the tray and adjust the feet height, or cement bed as required.

• Fix the plumbing and check for leaks

• Whether the tray has upstands or a flat top always silicone seal between the bottom tile and top edge of the shower tray on completion.

• Tile over the upstands leaving a 3-4mm gap above the top edges of the shower tray. Silicone seal the 3-4mm gap between the tile and the shower tray
  
  

• Always protect the shower tray during installation with a dust sheet.

• Do not use substances containing bleach when cleaning the shower tray after installation
