Before tiling a shower on drywall, it's crucial to apply a waterproofing membrane or paint-on liquid waterproofing. This acts as a moisture barrier, protecting the underlying drywall and framing from water damage. For enhanced protection, consider using a cement backer board instead of plain drywall, which provides a more durable and water-resistant surface for tiling.
