Copper Sinks: Everything You Need to Know

Looking for that something special for your kitchen? Sure, you can go with a spectacular backsplash or gorgeous countertops, but if you really want to make a statement that doubles as a smart kitchen choice (and at a way lower cost than, say, marble counters), consider adding a copper sink.

Many believe – wrongly – that copper sinks are fragile and unsuitable for heavy use. Copper isn’t just a pretty, decorative choice; it’s actually quite durable, eco-friendly, and downright beautiful to boot.

Here’s everything you’ve ever wanted to know about owning and using copper kitchen sinks:

What is a copper sink?

Copper sinks add distinct beauty to any kitchen (or bathroom – copper vessel sinks and even copper bathtubs are gorgeous and luxurious). They’re made (often by hand) of copper with a bit of zinc for strength.

Pros and cons of copper sinks

Like every sink material, copper has its advantages and disadvantages.

Pros:

• Durable and versatile
• Beautiful, timeless look
• Antimicrobial
• Eco-friendly; recyclable
• Extra-long lifespan
• Some finishes conceal damage
• Develops unique patina over time
• Large variety of styles
• Resistant to rust and corrosion

Cons:

• May require more maintenance than some other materials
• Some finishes prone to denting and scratching
• Costlier than some other materials
• Sensitive to acid, heat, and harsh cleaning agents

Copper gauge and quality

Beware of low-quality copper sinks; they are susceptible to damage and will not last.

A high-quality copper kitchen sink should be made of 99% copper and 1% zinc. Many less expensive sinks will also contain lead and mercury, so be sure to check your sink for purity.

Like stainless steel, copper thickness is referred to as “gauge” – the lower the number, the better the quality of the copper. A thinner gauge will often produce a tinny sound when using water and is more prone to damage. Look for 14- to 16-gauge copper for best quality.

You may notice words and phrases like “cold-rolled” or “annealed” in relation to your sink. That refers to the manufacturing process and does not have much impact on the quality or construction of your sink (though it’s recommended that you seek a lower gauge for annealed copper).

Additionally, check that your sink’s seams (nearly every sink will have them) are welded, not soldered, for best results. Soldering results in a weaker seam that’s prone to splitting apart after some time, while welded seams will not weaken or break.

Configuration options

Copper sinks are available in virtually every configuration – single bowl, double bowl, even triple bowl – to accommodate your cooking and cleaning styles. 

A single bowl copper sink is best for large loads and those who enjoy elbow room while washing dishes; a double bowl sink provides separate areas for dishes and glasses or dirty dishes and food prep; a triple bowl sink allows for even more flexibility, albeit typically with smaller bowls than the double.

Depending on the finish and layout, copper sinks can be modern (smooth and shiny copper sinks), rustic (hammered and rich copper sinks),or any style in between.

Installation options

A favorite sink for the ages: the copper farmhouse sink. The farmhouse sink’s front apron is perfect for displaying the beautiful sink material; just check with your kitchen installer that your cabinet can handle a farmhouse sink.

To accommodate an existing sink cutout, choose a copper drop in sink; for easier cleanup and a seamless appearance, look for a copper undermount sink. Farmhouse sinks (also known as apron front sinks) can be mounted over or under.

To add beauty and style to a pantry or bar, try a copper bar sink to make a statement; some are available in eye-catching shapes in addition to the typical square, round, and rectangular.

Finish and patina

Copper is available in a range of finishes and colors. Color options range from bright and shiny copper (like a new penny) to a deep brown shade. You may also choose from a smooth finish (more likely to show damage) or a hammered finish (conceals damage, less likely to dent).

One remarkable quality of copper – and one of the reasons that it’s so popular –  is that it develops a unique patina, or pattern, over time; it’s considered a living finish. With exposure to air, water, and other elements, the sink tarnishes, changing color over time. Exposure to acid (like orange or lemon juice) will strip the patina, but it will return with time.

You may have noticed copper that’s turned green on roofs or gutters (or the Statue of Liberty!), but that rarely happens to indoor-use sinks; it occurs from exposure to saltwater and weather changes, so don’t worry about your sink turning green.

If you’d prefer to slow down the patina (once it’s reached your desired finish), keep it dry when not in use, rinse it out after each use, and avoid acid-based cleansers and products. Wax the sink with copper wax, furniture polish, or beeswax every time you use it to slow the progression of the patina.

To strip off unwanted patina, use copper polishing creams not more than once or twice yearly (any more will damage the sink).

Once you’re totally satisfied with the finish, apply clear lacquer to preserve it.

Durability

Copper is highly durable, retaining its strength, beauty, and integrity even when recycled. It tends to be susceptible to scratching, and smooth finishes are likely to get “dinged,” but it adds to the sink’s character.

High-quality copper sinks are long-lasting and resistant to rust and corrosion.

Cleaning and maintenance

Copper sink care is slightly more complex than other materials, though it’s not an extremely high-maintenance material. It’s also naturally antimicrobial for a hygienic environment.

To keep your copper sink in optimal condition:

• Don’t use harsh or abrasive chemicals, cleaners, or brushes
• Avoid prolonged contact with lemon, orange, pineapple, mustard, and other acidic foods; rinse off quickly
• Clean with mild soap and water
• Pat dry with a soft cloth after every use
• Prevent water spots and mineral deposits by waxing regularly (reapply when water no longer beads on the sink’s surface)
• Use a gentle copper sink cleaner regularly for best results

Price

Copper is one of the more expensive sink materials, but it’s not unaffordable for most. Sinks start at under $200 for a smaller bar sink and prices range all the way up to several thousand dollars for larger sinks; you’re likely to find a large variety of options in your price range.
