Our wet room shower tray kit is ideal for those installing a modern and contemporary wet room system in the home. Complete with everything needed to construct your wet room shower tray, the contents within the kit are made from the highest quality materials for a long-lasting system you can rely on. Available in a number of sizes, this contemporary design is ideal for constructing a wet room whilst adding a modern look and feel. 

Why our foam cored Wetroom tray is so special:

Our Underlay Wet floors and Tile Backer Boards are made from extruded foam (not agglomerated styrene particles) with high compressive strength and tough impact resistant surface. As a result, this allows the use of tiny (20mm x 20mm) mosaic tiles. Customers can have total peace of mind that the tile will not sink into the underlay. 

Note: Beware of competitor products with densities of 12 – 24 tons per sq. meter.

The grid height may be adjusted to suit tiles from 8mm - 15mm thick and the factory fitted gasket around the drain provides a secondary waterproofing membrane.This unique grid/frame configuration also provides secondary under tile drainage. The Underlay tray can also easily be trimmed using a handsaw.  

Stainless drain kit:

The drain kit is specially designed for quick installation under the Wetroom former. When the former is fitted the trap is pulled up tight and sealed to the frame.

1 x Showerlay tray for level access with centre drain (requires under-boarding support).
