Nantucket Sinks Wellfleet-3218W is a new addition to our Cape Collection. By popular demand, we offer this dual-mount fireclay kitchen sink. A large single bowl design, it gently slopes and tapers to the bottom of the basin. The compatible bottom grid and drain are included. The top edge of the sink is finished with white porcelain enamel glaze so it can be used as a drop-in topmount or installed as an undermount. There are many benefits to fireclay; eco friendly in its need for less cleansers and its natural material. The wide basin is a bit larger than your average sink to maximize use and accommodate even the largest kitchen and bakeware with no problem. Glazed in classic white, the Wellfleet-3218W is here and ready to help you go apronless! • A note about fireclay sinks: due to the curing process, small surface cracks typically appear on the underside of the sink. These cosmetic flaws are from the molding process and do not affect the performance or visible luster of the sink.
