The Marmox Showerstone Wet Room Shower Tray is a self-supporting, barrier-free shower former that is ready to receive tiles, creating a base for a shower or wet-room. It is available in four sizes all being just 22mm thick at the outside edge but still managing an in-built gradient of 2%. This gradient is important to ensure water drains away.
This Wet Room Shower Tray is simple to install on either concrete floors or wooden floors where it can rest on the floor joists and comes supplied with a quality Tile Drain fixed to the base to simplify installation.
The ShowerStone Wet Room Tray is made of a robust polymer concrete using finely graded lightweight aggregate.
The Marmox Showerstone Tray is a solid, preformed shower base that can be tiled directly onto without the need for any surface treatment. It is easy to install and is strong enough to be supported by just wooden floor joists as wide as 400mm apart. Each tray can be neatly cut to size to fit a specific space in your bathroom.
Please Note - This product CANNOT be used in conjunction with vinyl flooring. It only supports tiled floors.
