What Are The Benefits of Copper Sinks?

To understand what makes copper sinks so desirable, here are a few facts about copper. Copper is known as the oldest metal used by humans on a large scale. Copper was first used in tools as far back as 10,000 years ago. It originated from Cypress and was mined there by the ancient Romans. Copper has amazing antimicrobial properties. Germs and viruses cannot live on copper. This is beneficial for any kitchen surface, especially sinks. Another benefit of copper kitchen sinks is they generally remain stain-free. You will need to be careful about acids.

Copper is a soft yet durable metal with interesting properties. Sharp objects can scratch copper. Hot appliances, containers, and utensils can mar the copper finish. Over time, copper tends to darken in color. This characteristic is called patina. Copper can be polished or natural. Both varieties of finishes are beautiful and a matter of choice. Copper sinks are more expensive than sinks made from other materials, and they require special care, but the end result is well worth the investment of money and effort.

How to Select Your Copper Sink

  • Size and Space - What size of a sink do you need? How much space do you have in your kitchen? Take time to visualize the sink in your kitchen. What details and finishes do you prefer? Do you like smooth copper or hand hammered?
  • Single or Double Sink - Do you prefer a single bowl or do you prefer the convenience and look of double bowls?
  • What Copper Sink style do you like? An Apron Front Sink extends all the way to the front of the cabinet. An Undermount Sink will be even with the countertop. If you’re looking for a stylish sink, a Copper Vessel Mount Sink sits on top of the cabinet and creates a beautiful focal point for your kitchen.
  • What Copper Finish do you prefer?

You may be able to customize and select the finish you prefer for your copper kitchen sink. In general, you can choose between textured and smooth finishes. Textured finishes are hand hammered in different styles such as Beehive, Bouquet, Grain, Heavy, Hood, or Light.

If you prefer a smooth finish with little to no texture, you can look at Antique Copper finishes, New Penny, Old Coin, Rose, and Weathered copper. As you look at the shades and copper finishes available for your kitchen sink, you can see the customization options enable you to create your own unique signature focal point for your kitchen.

How Difficult Is It to Clean A Copper Kitchen Sink?

It is easy to keep your copper kitchen sink clean. All you need is a sponge or soft microfiber cloth, some warm water, and mild dish soap. Avoid using scrubbing or scouring pads. Never clean with abrasive cleansers. There is no need to. Also, avoid placing too many heavy pots and pans in the sink at once. The sink may be scratched or damaged from the weight. Your copper sink with its antimicrobial properties kills harmful bacteria. You can dry your copper sink with a soft cloth.

How Are Copper Sinks Made?

Copper sinks are not mass-produced. Therefore, each example can differ slightly, depending on the workmanship and machinery used.  Before buying a copper sink, always confirm it is not “out of square” or “out of round,” depending on the shape. You may want to take measuring tools with you to the showroom to check for problems. Units out of true run the risk of failure. 

Copper sink production begins with ore extraction. Mining companies remove material from the ground and ship it to refineries for purification. These facilities separate the copper from its natural ore using various processes, including smelting, refining, and casting. Then they roll it into standard-gauge sheets, discussed below.

Copper sink manufacturers buy these sheets and then melt them at high temperatures before pouring the copper into molds. The metal then cools and the mold is taken away, revealing a beautiful copper sink beneath. Some manufacturers make copper sinks by hand. Skilled artisans hammer the metal until it is in the right shape, hence the hammered finishes we offer at CopperSmith. 

The next step is to finish the sink. The patina method gives copper its characteristic color and makes it appear slightly aged. Polishing and covering it in a thin veneer makes the sink shiny but less suitable for kitchen applications.  Copper sinks are rarely pure copper. Most are 99 percent copper and 1 percent zinc. Zinc increases copper’s durability and strength, and makes it more resistant to corrosion. 

Some high-end copper sink manufacturers use 100 percent copper. This decision improves the appearance of units but may decrease their lifespan and increase maintenance. One more thing to remember. Avoid placing acidic foods in your copper sink. Examples of acidic foods include oranges and tomatoes. Rinse your sink immediately if acidic food is placed in it.

Is The Gauge of A Copper Sink Important?

As you select your copper kitchen sink, you will find references to the gauge of the copper. The gauge is the thickness of the copper. Pay close attention to the gauge because it provides important clues about the quality and longevity of the copper. Your copper sink should last you forever if you care for it properly and choose the highest quality sink within your budget. Any sink with a gauge higher than 18 may dent easily and should be avoided. The lower the gauge number, the thicker and more durable the sink is.

The higher the gauge number, the thinner, more lightweight, and potentially less durable the sink will be. All of our copper kitchen sinks at World CopperSmith are made of high-quality 16 gauge copper or premium 14 gauge, which is 33% thicker.

You can feel the difference in quality when you hold a copper sink made of 16 gauge copper compared to higher gauge sinks. There is a definite weight and solidness. Here is a way to test the thickness of your copper sink: If you hit the copper, less expensive copper sinks (made with higher gauge copper) give a tinny sound. High-quality 16-gauge or lower sounds fuller in tone.

The most common sink gauge sizes are 18, 16, and 14. A lower gauge number indicates a thicker and more durable sink, capable of withstanding heavy use and resisting dents or dings. However, higher gauge sinks are lighter and may be more affordable. Consider your usage needs and budget when selecting the perfect sink gauge for your kitchen or bathroom, ensuring a blend of functionality and aesthetics for years to come.

Tap the sink with your knuckles to unveil its gauge. A 14 gauge sink will resonate with a deep, rich sound, indicating its sturdy craftsmanship and durability. On the other hand, a lighter, tinier sound will emanate from an 18 gauge sink.

You can customize your sink with a variety of options so it fits perfectly into your kitchen design and layout. Now that you have a little background information on copper and copper kitchen sinks, it will be easier to understand what makes the following the 5 Best Copper Sinks for Kitchens in 2022.

Copper farmhouse sinks get their name because they were common sinks in farmhouses, where the need for a large sink in the kitchen was essential. Plumbing was not always installed in these houses, so sinks had to be able to hold adequate water.

Now, plumbing is expected, but this type of sink remains very popular because of its versatility and ability to hold a large quantity of water and many dishes at once. Farmhouse sinks come in many styles and types, but we are starting with the Copper Farmhouse Double Bowl Apron Kitchen Sink.

Brief Buyer’s Guide to Copper Sinks

Here are a few things to consider as you select your favorite copper kitchen sink.

Consider the size of your kitchen

Copper sinks are large in size. This is normally a benefit, but if your kitchen is unusually small and space is at a premium, you’ll want to measure carefully to ensure you have enough room. Decide whether a single or double sink will better suit your needs and the kitchen space.

Installation of a copper farmhouse sink requires a professional

You will probably want to have your copper sink professionally installed to ensure it is done correctly. Copper farmhouse sinks and undermount sinks, in particular, are difficult to install and are worth the cost to have professionals handle the work.

Copper sinks should be welded, not soldered

Soldered seams can eventually leak and become gray over time. World Coppersmith sinks are created with the highest quality craftsmanship and full apron welded seams.

Drain considerations

The positioning of the drain on your chosen copper sink may slightly affect its draining effectiveness. The drains in most kitchen sinks are located in the center of the sink, but sometimes other locations are preferred. Confirm the size of the sink hole to ensure everything aligns. You may have a preference for the position of the drain that can be customized when the sink is made. The bottom of the sink will slightly slope downward so draining will not be a significant issue.

There are several installation methods for copper kitchen sinks. Top-mount installation occurs when the sink slides under the countertop with the rim’s edge holding it in place. These sinks tend to be exceptionally easy to install and regularly complement the surrounding countertop material. Sometimes, people refer to them as “self-rimming” because they hang in position and create a seamless surface with the countertops. 

Undermount copper kitchen sinks are another option. These don’t have a raised lip to hook onto the counter. Instead, installers place them underneath the countertop, supported by structures below. 

Undermount sinks are the top choice for homeowners with granite or quartz sinks. Undermounting prevents excessive strain on the surrounding material, making it less prone to cracking and other issues. 

How Do Copper Sinks Compare To Stainless Sinks? 

Many homeowners choose stainless sinks because they believe they are lower maintenance than copper alternatives. The copper eventually develops a patina, even when combined with other metals. It can also discolor if exposed to harsh cleaners or acidic foods, meaning it can require higher maintenance. 

Again, though, that’s where the gauge can come into play. Thicker copper sinks take longer to oxidize, meaning they could last longer than thinner ones. 

What Finishes Do Copper Sinks Come With?

Copper sinks come with various finishes, with some looking raw and others taking on a dark coffee or chocolate appearance. Which copper finish you choose is entirely a matter of personal preference. Some homeowners like lighter colors, while others prefer darker textures. 

Regardless of the gauge of your copper sink, you should note that products come with a “living finish.” This feature means that the copper will slowly change in appearance over time as the metal reacts with the water and cleaning products you put in your sink. 

Most reputable copper sink dealers offer four finish types:-

Polished copper

The copper has been polished until it takes on an attractive, vibrant shine. (Some variants also feature a protective clear top coat that prevents the copper from losing its luster). 

Matte copper

Slightly less shiny and may require regular polishing with commercial copper polish products. 

Even patina

Light patina that looks uniform across the sink

Dark patina

Similar to regular patina but leaves darker colors in low spots

Some copper sinks come with lacquer to protect the surface and prevent it from developing a natural patina. Most buyers prefer non-lacquered products, but lacquered varieties can sometimes be beneficial, but aren’t recommended for kitchens because of how easily the lacquer wears off. 

Note that copper sinks with a dark patina can lighten over time. Copper may react with acids in food that cause it to change color.
