How To Build Shower Base

Building a shower base starts with structure, slope, waterproofing, and drain accuracy. A shower base is not just the visible floor. It is the foundation that controls drainage, protects the subfloor, and supports long-term installation stability. Industry guidance commonly uses a slope of 1/4 inch per foot toward the drain, and code-based liner testing requires the receptor area to hold water during a leak test after liner installation.
