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.

If the hearth ends against a wall, you can use a tile cutter as you normally would. However, if the edge of your hearth ends with no surface pressing against it,you may want to look into rounded tiles. These give a smooth edge to your hearth and make sure cut edges aren’t visible. You can also see if the tile you have has pieces that have been glazed or rounded on one edge. You’d then cut the tile and place it normally, with the cut edge facing inward. 

There isn’t a one-size-fits-all best tile for a dog shower. Consider your budget, tile durability, aesthetics, and, most importantly, practicality. Avoid tiles your dog will slide around on. Pebbles are a great non-slip option, but are pricey and tricky to install. Glass might look modern, but it’s not scratch-resistant. Small, floor-rated ceramic or porcelain tiles are economical and have many grout lines that make the surface more slip-resistant. Pick a matte finish rather than a shiny tile if you want it to hide stray mud and hairs better.

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.
