Adjacent to the Galleria, a 15,000 square-foot fabrication facility, automated machinery, on-site slab inventory, and trained installers allow GranTops to provide a continuous supply of high-quality granite and quartz countertop products to our busy clientele, who are often working on projects that require quick turn-around times.

We feature granite imported directly from quarries in Brazil and other parts of the world, so GranTops is involved with every step of quality control, from the quarry to the end user – providing customers with rested assurance of a successful project outcome.
