Marble will cost upwards to $10/Sq Ft for the material alone, and the installations will see significant price increase if the project requires a custom design, mosaic or other fancy inlays. Marble’s best characteristics are noticeable when it’s well polished, and as a result they tend to become very slippery. Since slipping hazards are quite common with Marble, we recommend having area rugs with rubber matting on the bottom to maintain a good footing position. Marble. having a highly reflective surface, means its more likely to have visible scratches. We advise all of our customers to exercise great care when moving furniture over Marble.
