Definition
A curbless shower is a shower with no curb or step at the entry: the bathroom floor continues straight into the shower and slopes gently to the drain.
Curbless Shower, Explained
A standard shower has a raised curb to hold water in. A curbless shower removes it, so the floor is continuous and you walk straight in. The floor slopes toward a drain, often a long linear drain at the back wall or at the entry, to keep water inside.
To get the slope without a step, the shower floor has to sit lower than the rest of the bathroom. In wood-framed homes that often means lowering the joists or building up the rest of the floor. In concrete condo buildings, it depends on how much depth is available above the slab.
Curbless showers look open and modern and are much easier to use for anyone with mobility issues, which is why they’re popular for aging-in-place renovations.
Why It Matters for Your Project
Whether a curbless shower is possible, and how much it costs, depends on the floor structure. It’s a decision to make during design, not after demolition.
What to Watch For
- Ask how the floor will be recessed or built up to get the slope.
- A linear drain makes the slope easier and the floor look cleaner.
- Waterproof the whole bathroom floor, not just the shower area.
- Glass panel placement affects how much water reaches the bathroom floor.
