I do not recommend comparing countertop companies by one advertised price per square foot. Countertops are custom work. The final cost depends on the actual slabs and what has to happen between measurement and installation.
For a kitchen with approximately 50 square feet of countertop space, our general countertop pricing can start around $5,500. That is not a marble-specific starting price. Natural marble varies considerably in cost, especially when a project requires premium slabs, extensive vein matching, or additional material for an island or backsplash. High-end natural stone countertop projects can reach $15,000 to $20,000, depending on the material and work involved. We calculate the actual price after reviewing the selected slabs and project requirements.
Price can change because of:
- The marble variety, grade, slab price, and number of slabs required
- The amount of usable stone after accounting for veins, fissures, cutouts, and damaged areas
- The island size and whether it can fit in one slab
- Seam quantity and placement
- Sink, faucet, cooktop, outlet, and specialty cutouts
- Edge profile and countertop thickness
- Full-height backsplash or waterfall panels
- Cabinet level, support requirements, wall conditions, and site access
- Second-floor delivery, crane service, or an additional installation crew
- Plumbing, gas reconnection, painting, and other finishing work completed outside the countertop scope
In Charleston, about 75 percent of the projects we see use a standard flat edge. A double bullnose can add roughly 25 to 30 percent to the project cost, while a mitered edge can add about 50 percent, depending on the stone and scope. A waterfall on both ends of an island can add about 30 percent to the overall job. These percentages are planning guides, not automatic charges.
A full-height backsplash of about 30 square feet may cost around $1,400 when enough purchased material remains. If the backsplash requires another full slab, the starting point may be closer to $3,400. This is why slab layout and remnant availability matter. If a project is just short of material, we can check for a suitable remnant instead of automatically adding another slab.
