An elegant handcrafted trough sink with hand hammering detail in sparkling stainless steel. Because they are made by hand, each sink slightly different than the other. The hammering creates highs and lows to catch the light and create a truly artistic finish. Designed to be undermounted. This sink will naturally oxidzie if left untreated but a quick polish will bring back its luster! Crafted from 304 18 Gauge stainless steel. Uses a standard lavatory drain 1.5". Slight variations may exist up to .25".
