Linear Wet Room Screed Drain

One of our most advanced wet room drains is the Linear Screed Drain, which has been developed specifically for concrete or screeded floors and can be used on concrete slabs, planks and block and beam floors. The key feature of the Linear Wet Room Screed Drain is its height – the total height from the base to the top of the trough being only 67mm, making it perfect for today’s modern construction methods. Unlike a lot of wet room drains, the linear screed drain incorporates a unique waterless trap and a lifetime guarantee. Here at CCL Wetrooms our Linear Wet Room Drain system is available with one, two or three traps and a choice of stylish grill finishes.

  • Wet Room Waterless Trap

    The waterless trap of the Linear Screed Drain has been specially designed with a spring loaded mechanism which keeps the trap sealed when not in use. This ensures that even when left unused for prolonged periods the trap cannot dry out, making it ideal for situations where the shower is not in everyday use. The smart design of the linear trough allows the waste position to be rotated through 360° enabling installation in most scenarios with ease.

    • 360° rotatable waste position
    • Easy to clean and replace trap
    • No requirement to top up the trap during long periods of non-use
    • No siphoning of the trap due to other appliances

  • How to Specify

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

    Membrane: It is essential that the floor is waterproofed or ‘tanked’ using one of the RIW membranes. For solid floors we recommend the Tilesafe/Screedsafe membrane is applied to the shower area plus an additional one metre in either direction. FWM should then be applied to the walls of the shower area plus an additional 300mm and overlapped onto the Tilesafe/Screedsafe Reinforcing Tape

    Example: A single wet room waterless trap, 800mm Linear Screed Drain with square holes is: LSD1-800/TypeC
    Example: A double trap, 1000mm Linear Screed Drain with solid grill is: LSD2-1000/TypeA
    Example: A triple trap, 1200mm Linear Screed Drain with stone-infill grill is: LSD3-1200/Type S
