A copper sink can be a beautiful addition to any kitchen, providing a warm glow and vintage flair. Copper’s warm, reddish-brown color looks stunning against natural stones like marble or granite, as well as paired with wood cabinets and accents. Unlike stainless steel or porcelain sinks, a copper sink develops a natural patina over time, adding to its antique charm. Beyond aesthetics, copper offers practical benefits too. Here’s an in-depth look at why you should consider incorporating a copper sink into your kitchen design.

Benefits of a Copper Kitchen Sink

Heat Retention

One of copper’s standout qualities is its ability to rapidly adjust to surrounding temperatures. A copper kitchen sink absorbs ambient heat, so your rinse water won’t lose warmth as quickly as with other sink materials. The retained heat can help melt away stuck-on foods and allows you to use a lower water temperature while washing dishes. This heat retention delivers a more comfortable washing experience.

Antimicrobial Properties

Copper naturally repels and kills bacteria, viruses, and other microbes through a process called the oligodynamic effect. Studies show copper’s antimicrobial power remains even after repeated contamination and cleaning. With a copper sink, you can feel reassured knowing this surface has natural sanitizing abilities. The antimicrobial qualities reduce odors and degradation over time too.

Stain Resistance

While copper reacts to certain acidic substances like lemon juice or vinegar, it stands up well to stains overall. The material’s smooth, nonporous surface prevents stains from penetrating or sticking. Copper won’t absorb stains like more porous sink materials such as concrete, enamel, or fireclay. With proper care, a copper sink can maintain its vibrant look for decades.


Copper ranks very high on the Mohs scale of mineral hardness, making it an extremely durable metal resistant to scratches and dings. Though a soft metal, copper hardens significantly when worked and alloyed. Most copper sinks consist of 99.9% pure cold-rolled copper at 16 gauge or thicker. This combination of purity and thickness creates a sturdy, resilient material perfect for an oft-used kitchen sink.

Ease of Maintenance

Unlike many metal finishes, copper’s patina can be removed or restored with relative ease using a copper polish. This allows you to maintain the sink’s original shine or return it to a like-new condition when desired. If you wish to keep the aged patina, simply clean the sink by hand with mild soap and water. Avoid abrasive cleaners or scouring pads, which can scratch the finish.

Adds Value

A genuine solid copper sink qualifies as a premium feature, potentially increasing your kitchen’s value. The unique, high-end look combined with copper’s practical strengths make it a focal point that could help yield a higher price tag when selling your home. Even lower-cost copper-hued composite sinks add perceived value over basic stainless steel or enameled cast iron.

Environmentally Friendly

Copper ranks as one of the most sustainable metals, capable of being recycled repeatedly without loss of quality. Approximately 80% of the copper produced in the last 100 years remains in use today. When sourcing a new copper sink, look for manufacturers utilizing at least partially recycled copper. This diminishes the environmental impact versus mining entirely new copper ores.

Noise Reduction

A copper sink’s solid, dense composition absorbs sound and vibration more effectively than thinly rolled stainless steel. The material helps muffle noises from running water and clanging dishes. If noise drives you crazy while washing up, a copper sink could help restore some peace to your kitchen.

Styles of Copper Kitchen Sinks

Copper kitchen sinks come in several styles to match various decor tastes:


The farmhouse or apron-front sink features a large, wide rectangular basin with the front panel wrapped around the cabinet face. This style looks perfect in rustic, country, or vintage kitchens. Apron-front copper sinks often get paired with butcher block countertops and exposed brick backsplashes.


Undermount copper sinks attach below the countertop, creating a sleek, contemporary look. The material’s glowing warmth stands out beautifully against surfaces like quartz or granite. Undermount installation maintains countertop continuity and keeps sink edges seamless for easy cleaning.


Also called top-mount or drop-in, inset copper sinks fit into pre-cut holes in solid surface or stainless steel countertops. A rim around the sink edges keeps it neatly in place. Inset mounting maximizes countertop usage area since the sink occupies only its own cut-out space.


Vessel sinks sit atop the counter as freestanding focal points, often on decorative legs or pedestals. Their bowl-shaped basins get installed into the countertop rather than mounted below it. Vessels come in oval, round, or rectangular shapes. Copper’s eye-catching shine and patina make it an ideal vessel sink material.


These large but shallow rectangular sinks include multiple compartments and short divider walls between each basin. Bar sinks fit smaller spaces, while full-scale commercial sinks can span up to 60 inches wide. Their expansive size makes them perfect for active cooking and cleanup.


Corner copper sinks wedge into angled kitchen corners to take advantage of dead space not easily utilized with regular sinks. They feature pie-shaped or triangular bowls and maximize efficiency for smaller kitchens. Corner sinks can be undermount or self-rimming.

Buying Considerations for Copper Kitchen Sinks

If you’re tempted to add a copper sink to your kitchen, keep these key factors in mind while shopping:

  • Material – Seek sinks made from 99-100% copper, ideally 16 gauge or thicker for durability. Avoid thinner sinks prone to dents and scratches.
  • Construction – Copper sheets get shaped by hand-hammering or molded under extreme hydraulic pressure. Handmade hammered sinks cost more but offer artisanal uniqueness.
  • Finish – Natural copper tends to darken and dull over time. For prolonged shine, look for sinks with a durable clear lacquer or nickel finish.
  • Brand Reputation – Stick with established brands known for quality construction and materials. Read reviews to learn how any given sink stands up to heavy, regular use.
  • Sink Style – Choose a style harmonizing with your kitchen’s aesthetic, fitting available space, and meeting your functional needs. Measure carefully!
  • Dimensions – Confirm your selected sink’s length, width, and depth accommodate your plumbing, cabinetry, and preferred washing process.
  • Mounting Hardware – Universal sink mounting hardware allows replacing an old sink without making new counter holes. Purchase new specialized mounting tools if needed.
  • Maintenance Needs – While durable, copper requires more frequent gentle cleaning than other materials. Ensure you have time for proper care.
  • Budget – Genuine copper sinks cost $500-1000+, while copper-hued composite versions run $200-500. Set a realistic budget and stick to it.

Caring for a Copper Kitchen Sink

A copper sink’s stunning look comes with certain care requirements. Follow these tips to help your sink maintain its warm glow:

  • Clean regularly using mild dish soap, warm water, and a soft sponge or cloth. Avoid abrasive scrubbers.
  • Rinse thoroughly after washing to prevent soap residue buildup. Wipe sink dry with a microfiber cloth.
  • Apply a thin protective coat of food-grade wax monthly to shield from water spotting and superficial scratches.
  • Remove water stains using a copper polish paste. Rub gently with a soft cloth using minimal pressure to avoid removing the patina.
  • Avoid leaving acidic foods like lemon juice on the sink’s surface. Rinse promptly after contact to stop corrosion.
  • Prevent ding and scratches by using care when placing pots, pans, and dishes in the sink. Don’t drop heavy objects.
  • If desired, restore the original shine using a copper polishing compound. This removes all patina, so re-seasoning is required.
  • Consider hiring a professional copper restoration service if heavy corrosion, scratches or other damage occurs. DIY repairs risk further damage.

With attentive care and cleaning, a handsome copper sink can maintain its visual appeal and utility for decades, becoming a cherished kitchen fixture for years to come. The extra maintenance effort pays dividends in enhanced style and ambiance.

FAQs About Copper Kitchen Sinks

Q: Are copper kitchen sinks better than stainless steel?

A: Copper and stainless steel sinks each have pros and cons. Copper offers a more eye-catching, unique look and has natural antimicrobial properties. However, copper requires more frequent gentle cleaning and polishing to maintain its patina and shine. Stainless steel withstands heavy use with less maintenance but provides a more utilitarian, industrial aesthetic.

Q: Do copper sinks turn green?
