Planning a curbless shower
- Recess the floor. The shower area needs to sit slightly lower than the bathroom floor, or the subfloor must be built up around it.
- Position the drain. Place the linear drain at the back wall, or across the shower entry to act as a water barrier.
- Slope in one direction. With a linear drain, the floor only slopes toward the channel, so large tiles can run straight across.
- Waterproof generously. Extend the waterproofing well beyond the shower area, since there's no curb to hold water back.
Accessibility benefits
- No step at the entry
- Room for a shower seat or wheelchair
- Easier cleaning, with no curb corners for grime
Care
Clean the grate and channel monthly, and keep the hair strainer area clear.
