I would not recommend Cornerstone Tile to anyone. They do not stand behind their products. We bought a beautiful piece of quartz from them for the master bath which was supposed to be impenetrable to everything and anything. Within six months it was stained. They tried to fix it with a "band aid" but it didn't last. The owners of Conerstone were stumped and agreed that something was wrong, and promised they would stand behind the product. However, a year later when it was even worse and I called them again, they told me there was nothing they could do about it and we were on our own. We are very upset with Cornerstone Tile; we made a very expensive mistake doing business with them.
