The new and beautifully designed Harmony line takes its name from the natural cloud-like textures found in this tile. A graceful design sure to breathe beauty into many pools and spas.

This is a porcelain tile which is the only type that is recommended for pools, spas or water features. The difference between porcelain and other tiles is really one of quality rather than type. The clay used for porcelain tiles is simply purer and more refined, making them tougher, denser and more impervious to water. With a water absorption rate of less than 0.5%, porcelain tiles are less liable to stain and are usually more frost-resistant.

The shade of tiles or stone may vary within any given color which is an inherent quality that enhances their beauty. All pool tiles are high fired porcelain and colors can change with each die-lot.

Packaging Information - Case quantity for this tile is 21 Sq Ft per Case. Each case contains 20 sheets of tile.
This item is sold by the square foot only. Case quantity is only listed as a reference.

BEST ANSWER: Yes it is OK to use but make sure the water in the pool is below the tile before IT freezes. The freezing water is what damages the tile!
Hello. We are having our pool resurfaced and are trying to match existing older tile with new pool "spotters". This looks very close, but difficult to tell. if we send picture can you let us know if it is close, or can you send a sample? Thanks!

BEST ANSWER: You may send pictures to us of your existing tile, however pictures are not always accurate in depicting what the tile looks like in person. You can also call us and order a free tile sample. You just need to pay for the shipping.
