View of backsplash. Tiling by Brian Inc. fabricated the countertops and measured the space over the sink and custom made the medallion for the space. The tumbled marble was ground smooth and grouted using a three step grouting process to keep the surface flat and free of large pores. This top still cost less than granite and was done as soon as the base cabinets were installed. Total install time for countertops and backsplash was four days. The tops and backsplash were sealed using a multi-step process to give the surface a durable and easy to clean finish.
