How To Install A LWCC Slimline Shower Tray On Solid Floor
A step-by-step guide to installing your LWCC slimline shower tray on solid floor.
We recommend you read these instructions carefully and if in doubt please contact a qualified plumber. Inspect your product immediately for damage, size and colour. Do not install if not satisfied as no claims for consequential damages will be accepted.
We recommend that two people install the tray and all shower trays must be considered a two man lift at all times.
Please ensure the shower tray top surface is compatible with the intended shower enclosure taking into account the loss of dimension from the tiles. This is particularly if you have elected to recess the edge of the tray into adjacent walls.
Do not use putty, mastic or solvent based sealers in direct contact with your product. Use of these will damage the tray and render the manufacturer's guarantee invalid.
Items Required: Spirit Level, Silicone, Drill, Hole Cutter, Pencil, Hammer
A wooden plinth to suit the base of the tray needs to be constructed. Allow adequate space below the plinth for the waste.
Cut and fit an 18mm marine ply board to fit the plinth. Position the stone resin shower tray on the plinth and mark through the waste hole of the tray using a pencil.
Cut a hole in the ply at an appropriate size using a drill and hole cutter to suit the waste. The hole should be sufficient to allow the waste unit to tighten onto the base of the tray and not the ply.
Mix a stiff 5/1 mixture of sand and cement mortar prepared to manufacturers specification, with an anti-crumbling additive.
Spread it over the area evenly where the base of the stone shower tray will sit. Do not allow the mix to block the drilled waste hole in the ply.
Level to sufficient thickness to allow leveling and full support to the tray and sides.
Prior to fitting the tray, please check that it drains correctly.
Level the tray around the rim, place a bowl under the tray and pour in water. As the tray skin is slip resistant, large droplets of water will remain but large pools should not be evident.
Fit the waste to the tray and position the tray on the ply and sand/cement mix. Be careful not to obstruct the waste hole under the tray as this may cause leakage.
Ensure the tray is positioned against both walls and the tray is level using a spirit level.
Connect the waste pipe to the waste and water test the connections for leaks and tray water retention.
Allow the mix to set before commencing any further.
Once the mortar mix is set, apply a secondary silicone seal between the tray and the wall.
Tile down onto the tray on each wall using suitable waterproof adhesive then grout the tiles using anti-fungal grout.
It is recommended that you tile the plinth using the same method used for the wall tiling.
Make sure that all surfaces are clean, dry and dust free then generously seal the joint between the tray and tiles (refer to step 5 image for more detail), tray to plinth and plinth to floor with an anti-fungal silicone sealant.
Allow the silicone and grout to set before fitting the enclosure, it is strongly recommended leaving for at least 48 hours.
A complete water tight seal is essential, the floor and or marine ply support could be damaged if water penetrates through.
