The process takes two to four days, depending on the size of the area and your experience level. The first day involves assessing and prepping the existing tile, while the second day is for laying the new tile. This may take longer in complex areas. After letting the adhesive dry for 24 hours, grouting and sealing can be completed on day three. For larger projects or intricate tile patterns, expect the timeline to stretch a bit longer. Also, proper drying time between steps is essential for long-lasting results, which extends the project’s time.

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.

Natural stone floors, especially pebble-style tiling, are one of the least slippery options for a shower floor. Natural stone has a texture to reduce slickness, and pebble-shaped tiles add more visual and textural contrast while reducing slippage. Vinyl tiles are also designed with anti-slip texture for added safety. If you have a slippery tile, be sure to add a grippy shower mat to reduce the risk of falls.

Costs range from $5 to $15 per square foot for installation and $150 to $600 for repairs, depending on the material and complexity.
