Natural Stone Tiles
The term “natural stone” refers to a variety of mineral materials including slate, marble, limestone, travertine, granite and sandstone, each of which has slightly different properties. They are usually created by extracting them from quarries and then cutting and polishing. These tiles are beautiful to look at as each one is different and has its own pattern.
Natural stones vary in their absorption rating, determining their suitability for bathroom use. In general, sandstone is the most porous, travertine, limestone and slate have medium absorbency, while granite is relatively waterproof. Polished materials also absorb less water than honed or cleft surfaces. With the exception of granite and some slate, natural stone tiles will need to be treated with a sealing agent periodically to protect their surfaces.
