Curbless shower vs Curbed shower
Curbless showers eliminate the step into the shower; curbed showers use a raised threshold to contain water. The waterproofing, slope, and accessibility implications differ.
Curbless shower
Flush threshold, linear drain
Curbed shower
Raised threshold, center drain
How they stack up.
| Dimension | Curbless shower | Curbed shower |
|---|---|---|
| Cost (typical) | $8,000–$22,000 | $5,000–$15,000 |
| Accessibility | Wheelchair-accessible | Step required |
| Aesthetic | Reads as high-end residential spa | Standard residential |
| Waterproofing complexity | High; continuous membrane required | Moderate; curb contains water |
| Slab work (slab-on-grade) | Coring for linear drain | Standard drain installation |
| Tile slip rating (DCOF) | More critical; wet area extends | Critical inside shower only |
Curbless is the right call for aging-in-place plans, for high-end primary baths where the spa aesthetic matters, and for any wheelchair-accessible household.
Curbed remains the right call for budget-constrained installs and for shower locations where the linear drain and continuous waterproofing aren't justified by use case.
