The process of shower curb construction involves creating a raised barrier at the threshold of a shower enclosure. This barrier serves primarily to contain water within the shower area, preventing leakage into the surrounding bathroom floor. The assembly typically consists of a mortar bed, a waterproofing membrane, and surface tiling to integrate with the overall shower design.
A properly constructed barrier is essential for maintaining the structural integrity of the bathroom and preventing moisture damage. It directs water flow towards the drain and contributes to the aesthetic appeal of the shower space. Historically, raised thresholds have been employed in wet environments to manage water and protect adjacent areas, evolving from simple earth berms to sophisticated building components.
