Of course you will pay a bit more for granite than you will for other stone options, or man-made materials. However, when you think about granite's incredible ability to last forever even if you live in an area with freeze-thaw cycles, it becomes a smart, sensible choice.
Other materials will crumble in high-traffic areas, or deteriorate due to pollution, salt and other urban factors. Granite does not. It combines incredible resistance to wear and tear as well as a natural beauty and charm that other materials simply do no offer.
