The long-term performance of a tiled shower depends on a robust waterproofing system integrated into the initial design. This includes creating a proper pitch to the drain to prevent standing water and installing a tested, waterproof membrane that extends up the wall at least six inches above the flood line. Proper sealing at corners, niche edges, and plumbing penetrations is critical. Using industry-standard methods like Schluter or similar integrated systems ensures the structure remains protected from moisture-induced damage and mold growth.
