INSL8 Linear Shower Trays with Tanking Kit, Waste and Choice of Grate Designs INSL8 Linear Wet Room Shower Trays are made from XPS (extruded Polystyrene) and finished with a cement coating, allowing you to create a cost-effective, insulated substrate that can be tiled directly onto. INSL8 shower trays are 100% waterproof and are specifically designed to be lightweight and easy to install. They also feature a natural 2% fall to the drain to allow for efficient water drainage. Just like INSL8 Tile Backer Boards, INSL8 Shower Trays can be trimmed down using a standard blade or saw with no specialist tools required; the only limitation is that you are only able to cut up to 50mm off of each side of the tray (equal amounts off of each side).
