To waterproof drywall behind a shower, start by applying a primer designed for high-moisture areas. Once dry, follow up with a waterproofing membrane; this can be a paint-on liquid, a fabric sheet, or a roll-on barrier. Ensure all surfaces are covered thoroughly, with extra attention to seams and edges. Finally, seal around fixtures and joints with silicone caulk to prevent water penetration. Regular inspection and maintenance are key to sustaining the waterproof barrier over time.
