Marmox Showerlay Plinth 1500x1000x100mm

Non-Stock | | 2-3 Working Days


For where it’s not convenient to install a floorlevel shower base because you cannot dig up the concrete floor, for example, if you live in a flat. An easier alternative to excavating beneath the shower area is to have the drainage above the floor. This would mean that the Shower base would be raised above the floor, and has previously been achieved by the installer fitting a timber frame to hold the shower former just above the drain. This item meaasures 1500mm x 1000mm x 100mm.

Marmox Plinth is the simple solution to this problem. It is a piece of dense waterproof XPS that is 100mm thick, so therefore raises the height of the shower base by 100mm. This allows the gully and drainpipes to sit neatly inside it. It also provides a perfectly level surface which is necessary and difficult to achieve when make in a timber frame.

Marmox Plinth is suitable for use with our Showerlay and Showerstone products.
