Showerlay

Showerlay

Easily create a sloping wetroom floor! Showerlays are a vital part of a wetroom. These pre-sloped flooring panels with integral drainage are used to create 'level access' tiled shower areas.

-Available From Dec 1st 2025-

Complete tiled wet rooms or simple shower areas are made using the Marmox system – a combination of the Multiboard Showerlay and our range of waterproofing products.

Showerlays provide a built-in drainage area beneath the shower head, working alongside Marmox Multiboards on the walls and surrounding floor. This combination offers an exceptionally stable, insulated, and fully waterproof substrate to tile upon – ensuring a long-lasting, leak-free wet room.

For all wetroom situations, Multiboard Showerlay offers a reliable and straightforward solution.

NEW Waterproof Fleece Layer

A Fleece now comes pre-attached to the shower tray, offering installers extra convenience and protection. The fleece provides further waterproofing around the edges, safeguarding the critical junctions between the tray, floor, and walls. It also offers further decoupling, absorbing minor substrate movements and reducing the risk of cracks in tiles or grout. Practical dotted lines are printed directly onto the fleece, allowing the tray to be trimmed by up to 100mm on any or all sides, making it easy to achieve a perfect fit on site.

Ready for tiling straight from the box, the Showerlay Fleece ensures a fully waterproof, durable, and reliable finish, giving installers confidence and saving time on every wetroom project.
