Nantucket Sinks 33-Inch farmhouse fireclay sink with Pietra Sarda finish. Part of our Vineyard Collection, this sink has an artistic finish to create the look of Sardinian stone with its natural variations, full of depth and character. Finished on all 4 sides lets you choose the plain or fluted apron front. There are many benefits to fireclay. Its glazed surface inhibits bacterial growth more than stainless steel. It is eco-friendly requiring less cleansers. Made and hand finished in Italy, each sink is unique. Due to the firing process, dimensions are nominal and may vary to actual up to .25". Custom cabinet or apron cabinet required. * 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.
