Setting a shower base starts with checking the subfloor, wall framing, drain location, and finished bathroom layout. A shower base must sit firmly, drain smoothly, and connect correctly with the waterproofing system. If the floor is uneven or the drain is misaligned, the base may rock, leak, or create standing water after installation.

Several installation references state that the shower subbase or liner should be sloped at 1/4 inch per foot toward the drain, and the finished threshold should stand at least 2 inches above the drain level to support proper drainage and code-compliant receptor construction.
