Curbless Showers in Meridian, Idaho
Flush, barrier-free entries built by recessing or building up the floor so the slope still works.
Short answer
A curbless shower has no raised threshold: the shower floor is continuous with the bathroom floor. To drain correctly the shower area must still slope, so the floor structure is either recessed between joists, built up across the whole room, or fitted with a linear drain and a single-plane slope. Structure, not tile, determines whether curbless is possible.
Structure decides feasibility
A curbless entry needs roughly a half inch of fall for every foot of shower floor. That depth has to come from somewhere. On a slab, the slab may be cut and recessed. On a framed floor, the subfloor may be recessed between joists, or the surrounding floor built up so the shower can sit lower relative to it.
- Joist direction and depth relative to the shower area
- Whether the floor is slab-on-grade or framed
- Ceiling access below for drain routing
- Transition to the adjoining floor covering
Keeping water in a shower with no curb
- A linear drain at the back wall or at the entry line
- Sufficient shower depth so spray does not reach the opening
- A fixed glass panel sized for the fixture position
- Waterproofing extended beyond the shower footprint into the room
