What is a recommended practice when tiling a shower area?

Using waterproof membranes to protect against water damage is a crucial practice when tiling a shower area. This method is essential because shower areas are exposed to high moisture levels, which can lead to water infiltration and damage to underlying structures over time. By applying a waterproof membrane, you create a barrier that prevents moisture from seeping into the walls and substrate, minimizing the risk of mold growth, rot, and structural deterioration.

While other practices may have some relevance, they do not provide the same level of protection. For example, using epoxy grout can improve stain resistance but does not address the critical need for waterproofing. Installing ceramic tiles directly on drywall is not advisable since drywall can easily absorb moisture, leading to damage and compromising the integrity of the wall. Leaving gaps for water drainage is important for proper water management, but without the foundational protection offered by waterproof membranes, such measures would be insufficient for ensuring the longevity and safety of the tiling work in a wet environment like a shower.
