Marble costs roughly $10.00 per square foot, and the installation pricing does increase if the project requires a completely custom design, fancy inlays or mosaics. Some of the best attributes of Marble is noticed when it’s very well polished. However, as a result of this maintenance process, they’ll end up becoming quite slippery. We recommend using big area rugs with gripping rubber matting under them to maintain a good grip. This helps prevent people from accidentally falling, especially while wearing socks. Since Marble is a highly polished type flooring system, we advise all customers to be extremely cautious when moving furniture over Marble flooring.
