Channel Linear waste Drains in a modern bathroom
  1. Why do I have to select the kind of drain I need. What are the choices?

Drains allow for a either horizontal or vertical drainage. In most instances a horizontal drain will be suitable, running just underneath the existing room floor. A vertical drain is only required where the existing drainage is so arranged or where there are obstructions preventing a horizontal run to the waste pipe.

  1. What is a linear drain? Can I have one?

Most wetbases have a small square drain either in the centre of slightly offset towards one end. A linear drain is a rectangular drain usually situated towards one end of the linear wetbase. It is particularly suitable where large format tiles are preferred over mosaic tiles. The wetbase has to be expressly for a linear drain and generally it is a little more expensive than traditional bases for square drains.

  1. Where does the drain sit—how much space does it need?

Wetrooms Online use a drain made by Dallmer, noted for its efficiency in taking away large volumes of water quickly. It is only 80 mm deep and so is easily fitted beneath the bathroom floor/wetbase with enough space to connect to a waste pipe. It does not need to be supported because it screws up into a preformed fitting on the bottom of the base. However, our advice is to build a support with ply on noggins between the joists upon which the drain can be positioned.

  1. How do I stop water flowing into the rest of the room?

A shower screen fitted along the long side of the wetbase resting on the tiles will prevent water from splashing or running into the rest of the room. They can be bought in a variety of sizes and designs from very simple clear glass screens to hinged versions, wall fixed or freestanding, etc

  1. Can the wetbase be made to fit any size of space?

Yes. Each base can be cut to make it fit any space. Ideally choose a size that is a little too big and cut the excess away with a good quality handsaw taking care to ensure the contours of the base that ensure the water is channelled into the drain are not compromised.

  1. Do I need to waterproof outside the shower area?

No. Providing a shower screen is fitted to prevent the escape of water into the rest of the room, there is no need to waterproof outside the shower area. Waterproofing is needed on the shower walls and it is usual to extend waterproofing onto the floor immediately outside the entrance to the shower area.
