Big Box Retailers vs SoLuna Copper, Pt. 1

What do you get when you buy a SoLuna copper sink versus a Lowe’s or Home Depot copper sink? You get a lot more, and we have summed up the details in three parts for you to see for yourself.

Lowe’s and Home Depot may be offering a similar copper kitchen sink for slightly less than what we sell ours for, but the differences are big. We purchased a farmhouse sink from each of these big box stores to conduct a side-by-side comparison.  In our testing, we found several issues with their sinks that are important considerations to think about if the cheaper price tag is worth it.


The Weight Difference

The true test is the actual weight of the copper sink. The Lowe’s farmhouse sink (33” x 22” x 9”) weighs 35 lbs.  Our basic model SoLuna farmhouse sink at the same size weighs 40lbs, and our Fernanda copper sinkweighs 42lbs, which means our sink is about 20% heavier!

Copper thickness is measured by gauge. All of our SoLuna kitchen sinks are made from 14 gauge copper, the thickest available on the market for copper kitchen sinks. Although Lowe’s and Home Depot claims their sinks are made of 14 gauge copper, the true weight suggests a much lighter and thinner 15-16 gauge.

The thickness of copper will have a significant effect on how well the sink wears over time. Thicker copper is especially important for kitchen sinks that see a lot of action and heavy use every day.

So, always check the gauge when shopping for copper sinks. A thicker gauge will be more expensive at first, but it will outlast thinner copper sinks and prove its value through longevity.

Country of Origin

The Lowe’s copper sinks are made in India. Our SoLuna copper sinks are made by talented artisans in Santa Clara del Cobre, Mexico. They use 99+% copper and ~1% zinc for strength.

You can buy any SoLuna copper sink with confidence knowing they are lead-free and crafted by the most talented coppersmiths in the world.  Our artisans take pride in their work and skill that has been handed down through their generations.


A lighter/thinner gauge copper produces a hollow, tinny sound when water flows from the faucet into the well of the sink. Often lower quality sinks are insulated with foam blocks in an effort to help dampen the loud, drumming sound.

When testing these sinks for sound, we found a big difference. Our SoLuna copper sink sounds lower and pretty quiet, signaling a more substantial, thicker product.  Both Lowe’s and Home Depot’s copper sinks sounded higher and tinny, and will likely need insulation and extra material around the well under the sink to reduce the loud noise.
