Novatto's basket strainer drain is exclusively created to match our copper kitchen, bar and prep sinks with 3.5 in. drains. A hammered copper strainer drain is a stylish and functional accessory adding a touch of rustic charm to the kitchen. Our basket strainer drain is not plated, it is made of solid copper, hand-made and hand hammered then hand-dipped in a patina solution and rubbed to the desired coloration. The last step is to hand-applied a temporary oil coating. This drain is made of high-quality copper hand-hammered to create a unique texture and patina. It features a basket strainer preventing food particles and debris from clogging your pipes and a removable stopper that allows you to fill your sink with water. Our copper drain actively kills bacteria due to the natural antibacterial properties of copper. E-Coli bacteria for example will live on stainless steel for 34-days, only 4-hours or less on copper. Since these copper drains/strainer-stoppers are made of solid copper, they will weather and patina along with your copper sink. Your drain, in no time short, will be beautifully weathered to match your sink from normal use. Let your style flow and enjoy Novatto's Limited Lifetime Warranty. Supreme packaging and double boxing ensure damage-free delivery. Novatto's customer service is always here to answer any additional product questions.
