Prep your bathroom wall for tile by ensuring it’s clean and stable. Remove old wallpaper or paint and fill in any holes or cracks with a patching compound. Sand the surface to create an even base and apply a primer. Next, install a tile backer board (cement board) to provide a water-resistant layer. Ensure it is secured properly with screws and seams taped with mesh tape. Finally, apply a waterproof membrane over the backer board to fully protect against moisture.
