Curbless Shower
A shower with no raised threshold — water containment relies on slope, a linear drain, and continuous waterproofing.
What curbless shower actually means.
Curbless showers remove the curb between the shower and the bathroom floor, creating a flush threshold. Water stays contained through accurate floor slope (typically 1/4" per foot), a linear drain, and waterproofing that runs continuously from the shower pan into the bathroom floor (typically a Schluter-type system). Curbless reads as higher-end design and supports aging-in-place use without retrofit.
