Nantucket Sink is a 30" reversible workstation farmhouse fireclay sink. The interior ledge is designed to hold the included wood-cutting board. This helps make tasks more efficient and keep your countertops clear. This sink is reversible so the apron style you like can be displayed. One side has an arched design on its apron front while the other has a 2-inch high horizontal ledge. The smooth glazed finish is scratch and stain-resistant and shows off the sink's elegant lines. The sides of the sink have a slight taper from top to bottom. There are many benefits to fireclay. Its glazed surface is eco-friendly requiring fewer cleansers. Apron height is 9.75 inches. Due to the firing process, dimensions are nominal and may vary to actual up to 0.25". A style base cabinet is required to support this sink. A note about fireclay: Small cracks will appear on the unglazed underside of the sink, these are cosmetic only and have no impact on the performance of the sink.
