To tile over drywall in a bathroom, start by ensuring the drywall is smooth, clean, and free from any damage. Apply a waterproofing membrane or primer designed for wet areas to protect against moisture. Next, mark your layout lines to guide tile placement. Spread a layer of thin-set mortar with a notched trowel, and press the tiles in place according to your design. Use spacers to maintain even gaps for grouting. After the mortar sets, apply grout, wipe away excess, and seal the edges to make your new tiled surface waterproof and durable.
