To waterproof drywall in a shower, first use cement board instead of regular drywall. Apply a waterproof membrane, like a liquid waterproofing solution, over the board. Seal all joints with fiberglass mesh tape and waterproofing sealant. Finish by applying waterproof thin-set mortar before tiling. This method ensures your shower is effectively protected from moisture.
