Linear Wet-Dec

The Linear Wet-Dec pre-formed shower base has been developed specifically by our team at CCL Wetrooms to allow the installation of a wet room on a timber floor. Available in a range of sizes, this linear wet room drain has a built-in gradient to ensure water from the shower is directed towards the integral linear drain, giving a sleek and stylish finish. The key feature of the Linear Wet-Dec is its two way fall which allows the tiling to be laid without diagonal cuts, therefore making it ideal for use with large format tiles. The integrated linear wet room drain is available with one, two or three traps and a choice of stylish grill finishes.

Dec

Floor gradient showing position of tile trim & deck areaThe Linear Wet-Dec is manufactured using a high density XPS foam with a mineral coating on both sides, making them both lightweight and easy to handle, whilst maintaining good thermal properties and compressive strength. The dec has a pre-formed 12mm fall, providing a consistent two way gradient every time. The clever design allows for far higher flow rates than a traditional four way fall Dec, whilst the linear drain makes it ideal for the installation of format tiles. Each Linear Wet-Dec is supplied with a stainless steel trim for detailing the difference in tile heights where the dec meets the remainder of the bathroom floor (see image for details).  
In addition to our range of stock sizes, CCL Wetrooms are also able to offer a bespoke design service to fit your linear wet room drain – please contact our technical team to discuss your requirements.

  • How to Specify

    To specify your Linear Wet-Dec, first select the required number of traps (depending on the required flow rate), followed by the grill length and finally the grill finish.

    Example: A single trap, 1800mm x 900mm, Linear Wet-Dec with solid grill would have the code: LWD 105/Type A


    Membrane It is essential that the floor is waterproofed or ‘tanked’ using one of the waterproof membranes. For timber floors we would recommend that RIW Tilesafe membrane is applied to the entire wetroom floor. RIW FWM should then be applied to the walls of the shower area plus an additional 300mm and overlapped onto the RIW Tilesafe Reinforcing Tape.
