To waterproof a bathroom before tiling, start by cleaning the surface to remove any dust or debris. Next, apply a waterproofing membrane, such as a liquid or fabric membrane, over the surfaces that will be tiled; this includes floors and walls around the shower area. Ensure all seams and joints are properly sealed with waterproof tape or a specified sealant. Finally, allow the membrane to fully dry according to the manufacturer's instructions before beginning the tiling process. This step is crucial to prevent water damage and mold growth behind tiles.
