In time they will chip off like any other kind. It really comes down to how well you maintain your pool and chemicals.

If your pool is in a freeze/thaw part of the country, and exposed to such conditions, you most certainly may have potential problems. That holds true for any tile types.

If proper prep, application and the correct setting materials are used, you'll have longevity of the tiles. Tile setting materials, prep materials and setting methods have changed quite a bit in the last 10 years. There are really good products for specific types of tile.

Pool chemicals don't play much of a part in tile failure. It's all in the installation.

Water intrusion can pop tiles over time so it's best the grout joints and any joints surrounding the tile are sealed. This happens mostly in freeze/thaw areas.

Thank you so much! We are in Houston, so we rarely have freeze/thaw conditions.

Ok then you have some wiggle room.

Still, any tile used needs the proper prep, temp conditions and setting material to provide a solid job. Same holds true for plaster and coping stone application and install.
