Our Kitchen Drains are made of SOLID COPPER and they are exclusively produced for Artesano Copper to match our Kitchen and Bar & Prep Sinks with 3.5" drains. The finish of these drains is called Weathered Copper (WC).
Since these copper drains/strainer-stoppers are made of solid copper and have a spring loaded center post for a tight seal and they will weather and patina along with your copper sink. In short order, your drain will be beautifully weathered to match your sink from normal use. You may use plumbers putty to install into sink.
Our 3.5” Basket Strainers are not plated; they are made of solid copper and hand dipped in a patina solution, hand rubbed to the desired coloration, and hand applied a temporary oil coating. Our copper drains actively kill bacteria due to the natural antibacterial properties of copper. E-Coli bacteria for example will live on stainless steel for 34 days, only 4 minutes on copper.
