After… amazing they used: 2×12″ Nero Black Marble polished $12.95 (currently..website has most up to date prices, as they change).
"I was terrified to order marble tile through the internet, but it was the BEST experience. The sample was great, ordered 130 square feet, which arrived fast & in perfect condition. The price was 20% of local stores, and Builders Depot were the best people to work with - fast, helpful, kind... you name it. AWESOME internet experience. Cannot recommend highly enough!"
