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.

Taking the time to properly prepare your tile backsplash before painting and treating it with care afterward is the best way to ensure its longevity. While the tile can last for the life of the home, you may have to repaint it after a few years. However, using only mild cleanser and water to keep it clean can maximize the paint's lifespan.

While you shouldn’t use thinset mortar on its own as a floor leveler, it can work alongside other products to help level floors. For instance, you could start with a self-leveling compound, let that dry, then apply backer board with thinset mortar to help fully even out the floors ahead of laying tile.

When choosing tiles for a shower floor, avoid highly porous tile materials, like those with a water absorption rating over 7%. Don’t use non-vitreous tiles, or tiles fired at low temperatures, because they will absorb more water. If you use a highly porous tile in the shower, the tiles can wear down faster, meaning they’ll need to be replaced much sooner.
