Travertine is a natural stone that is a form of limestone and almost looks like marble. It is available in many earth colors, and has beautiful natural veining. It is less expensive than granite and some other marble types, but not the best suited for certain high traffic areas.
It is important to note that travertine is a porous material, and it requires regular sealing to maintain its quality and prevent staining from spills. Additionally, it may require more delicate handling to avoid chipping or cracking, compared to harder stones like granite.
