Grey marble is one of the most visually appealing marble slabs. From light grey to dark grey marble, plenty of options are available. Grey marble countertops, backsplashes or flooring can add vibrance to any space and up-the-ante without being too flashy. Grey marble can be used on bathroom countertops, table tops, indoor flooring, bathroom walls, and even backsplashes. Grey marble can make any space look rich with a subtle grandeur, but make sure you pick the right spot where it will look the best in your home. Marble can last for decades, but it requires the right amount of maintenance and care. Keep that in mind while exploring your options.
