There is no definitive answer to this question as the cost of a marble kitchen top can vary greatly depending on a number of factors. These can include the size and shape of the countertop, the type of marble used, as well as any special features or finishes that are applied. With that said, marble countertops typically range in price from $50 to $200 per square foot installed.
So, if you were to install a marble countertop that was 10 square feet in size, you could expect to pay anywhere from $500 to $2,000 for the materials and installation. Of course, if you opt for a higher-end type of marble or choose to add special features like edge treatments or backsplashes, your costs could be even higher.
