Installing kitchen countertop tiles on a mold and moisture-resistant cement backer board is one of the best options. When fitted correctly on top of a plywood base, it’s stable and long-lasting. Old-fashioned cement board is economical, cuts neatly and easily with a circular or jigsaw, and screws into plywood without any difficulty.

Yes, you can tile over existing tiles in a bathroom, but it is not always recommended. For this method to be successful, the original tile surface must be clean, flat, and free of damage such as cracks, unevenness, mold, or mildew. While tiling over existing tiles can save time and money, there are potential drawbacks. The new adhesive may not bond properly, and the process adds extra weight to the wall or floor. Additionally, the increased height of the surface could interfere with door clearances. For the best and most durable results, removing the old tiles before installing new ones is generally the better option.

Popular options include ceramic, porcelain, stone, and glass tiles, chosen based on the area (bathroom, kitchen) and desired aesthetic.

The lifespan of tile flooring can vary significantly based on the material and maintenance. Generally, tile flooring can last anywhere from 10 to 30 years, but high-quality, well-maintained ceramic tile can last 75 to 100 years. To achieve a longer lifespan, you should clean the tiles and grout regularly, reseal the grout annually, keep the floor dry, and avoid placing extremely heavy items on it to prevent cracking. Choosing a high-quality tile (Grade 1) will also contribute to its longevity.
