Everything You Need To Know About Copper Kitchen Sinks

If you are in the process of planning a kitchen renovation, one of the main considerations will include the type of kitchen sink you plan to use. Here is a bit of important information on copper kitchen sinks.

Copper Sinks

The copper sinks come in hammered copper if you are looking for a rustic or country style kitchen or smooth copper if you prefer a modern kitchen.

Distinctive Features

Copper is a malleable and extremely soft metal. The best quality cooper sinks are usually made from 99% copper along with 1% zinc that adds integrity and strength. Before you invest in a copper sink you must ensure that the sink has been certified that it is mercury and lead free. The imported and cheaper sinks often feature a mixture of metals.


The copper sinks come in hammered and smooth. The majority of the hammered varieties come from Mexico, where the artisans use old methods. The term “hand hammered” is used to distinguish these unique sinks from the types made by machines. The copper-sink manufacturers in the U.S. focus more on the commercial type sinks similar to the types used in restaurants. These are the types of sinks that feature smoother finishes. The Patinas include shiny and bright onto chocolate-colored and dark.

Similar to the stainless-steel sinks, the gauge of copper is important when you buy copper kitchen sinks. The thicker gauge varieties are more costly yet far more durable and will be less prone when it comes to dents. If the copper is “cold rolled” look for a minimum of a 16 gauge and if the copper is “annealed” look for a 14-12 gauge.

Shapes And Sizes

The kitchen sinks typically come in an under mount-sink style, Farmhouse sink style and standard drop-in.

The Advantages Of Copper Sinks

Copper is naturally antimicrobial and is a fully reusable and recyclable metal. The hammered varieties are more durable and less susceptible to dents and scratches. The patinas also grow deeper and richer over time which gives the sink an aged and worn-in appearance,

The Disadvantages Of Copper Sinks

The smooth varieties of the copper sinks show up dents and scratches and acidic liquids or foods can lighten or damage the patina. Frequent waxing will be required to protect this patina and cleaning chemicals that contain harsh chemicals will need to be avoided.


The better quality copper sinks typically start at around $150. You need to be careful of the cheaper versions of these since as integrity of these materials is more likely compromised with the use of mercury or lead.

Additional Considerations

There are other considerations when it comes to choosing copper kitchen sinks. While the maintenance and care is not very different to other sink types, you should think about waxing the sink. The appeal of copper lies in the natural patinas, but many prefer to maintain a look that is more constant. Copper wax shields the finish from acids and chemicals which usually cause blemishes and spots.
