The 16″ Rippled Copper Vessel Sink by SoLuna is handcrafted from a single sheet of thick, 14-gauge hammered copper and shaped into a softened hexagonal form. All of the SoLuna sinks are handcrafted using only lead-free, hand-hammered copper by 3rd generation coppersmiths. SoLuna Copper Sinks are made to last a lifetime!
