Mosaics are excellent as stand-alone pieces or used with complementing stone, ceramic or glass field tiles. Blending products from multiple boxers will ensure a uniform look. Natural stones have substantial shade variations. Glass mosaics are not recommended for floor applications as they are susceptible to scratching. Mosaics containing copper or metal may not be used where there is consistent moisture in wet areas or submerged. This included, but is not limited to: showers, steam showers, fountains and pools.
