You can technically install tile over tile, but we don’t suggest it. Installing tile over any surface that isn’t a completely flat and prepared subfloor will result in a shoddy overall job, uneven flooring, tiles that don’t adhere, extra weight, gaps, cracks, and room for moisture and dirt to enter. For the best results, only install new tile on a flat, sanded surface like subflooring or concrete that is prepared for tile.

If you have asbestos tile and would rather tile over it than remove it, or if your existing tile is completely flat and bonded tightly to the floor, you may be able to tile over existing tile. But experts recommend thinking twice before you do.

For best results, you should remove the toilet in a bathroom before removing tile or installing new tile. If you don’t remove the toilet, it will be harder to fully waterproof the tile around the toilet, which could increase the risk of mold growth or plumbing leaks. If you have trouble removing the toilet, hire a plumber to help.

When choosing between porcelain and ceramic tile, the best option depends on your specific needs, budget, and project application. Porcelain tile is generally more durable, denser, and harder than ceramic, making it a good choice for busy, high-traffic areas. It also offers superior moisture resistance, making it ideal for moisture-retaining spaces. However, porcelain is typically more expensive, and its hardness can make it brittle, potentially causing it to crack if a heavy object is dropped on it. In contrast, ceramic tile is a more budget-friendly option with lower material and installation costs. It is softer and easier to work with, making it a great choice for DIY projects. While not as durable as porcelain, ceramic is still a quality material suitable for many home applications, particularly small, decorative projects.

If you’re handling your tile removal yourself, seal the room using painter’s tape and heavy-duty contractor bags to prevent dust and shards from escaping. Use a claw hammer or a pry bar and a mallet to get behind the tile and pry it away from the floor or wall. Once your tiles are all removed, sweep everything into contractor bags for disposal, being careful not to overfill them. Make sure you wear a dust mask, safety goggles, and work gloves to keep yourself safe from injury while you work.
