Copper Sink Buyer's Guide

Big Box Retailers vs. SoLuna

Our SoLuna artisans have developed a unique tighter hammering pattern that produces not only a harder surface sink, but also an appealing look that is not to be found elsewhere.
SoLuna Competition

As the leading copper sink retailer in the USA for over 15 years, we have always prided ourselves on offering the best handcrafted copper sinks for the lowest price. We are able to do this because we make our sinks directly and sell them to you without a middleman. So how is it that the two largest big box DIY retailers in the US are offering a copper kitchen sink for less than what we sell ours for? We purchased a farmhouse sink from each of these two megastores and did some side-by-side comparisons. The copper sinks they are offering are vastly inferior and the small additional price you will pay for a genuine SoLuna copper sink will save you the expense and hassle of replacing your copper kitchen sink in just a few years. Why? Read on…


The Weight Difference

The big box store farmhouse sink (33” x 22” x 9”) weighs 35 lbs. Our basic model farmhouse sink at the same size weighs 40lbs and our Fernanda version weighs 42lbs making our sink nearly 20% heavier! Although they claim their sink is made of 14 gauge copper, the weight of the sink suggests a much lighter and thinner 15-16 gauge. Copper is a soft metal and the thickness has a dramatic effect on how well the sink wears over time. This is especially important for kitchen sinks that are under a constant barrage of pots, pans, tools and cleaning products. In copper, the thicker the gauge, the lower the number. Though you’ll find bath sinks made from 20 gauge to 16 gauge, most kitchen and farmhouse sinks range from 18 gauge to 14 gauge. SoLuna Kitchen sinks are made from the heavier 14 gauge copper. When shopping for copper sinks, always ask about the gauge. A thicker gauge sink will be more expensive but will be well worth the extra cost.


Country of Origin

The big box store copper sinks are made in India. We’ve found from sampling many sinks made worldwide that lead in the copper can be a problem. Our SoLuna sinks made by the Santa Clara del Cobre artisans are the exception to that. You can buy our SoLuna sinks with confidence that they will be lead-free and made by the most talented coppersmiths in the world that have been making hand hammered copper products for many generations.



A lighter gauge metal can sometimes produce a tinny sound when the faucet is turned on and water drums on the sink surface. For this reason you’ll often find lower quality sinks insulated with foam blocks in an effort to help dampen the sound. Thin, light gauge copper will also dent more easily, which is a big consideration, especially for kitchen farmhouse sinks. In testing these sinks, we found there is a significant difference between the big box sink and our genuine artisan made copper sink. Our SoLuna sink sounds deeper and solid, signaling a more substantial product. By contrast, the big box sink sounds light and tinny, and will likely need some type of sound dampening.



The big box sink apron supports are visible on the underside of the apron and are welded together with only a few small dots of weld material. This type of welding does not hold up well and can break during shipping, or worse, after it has been installed in your kitchen. Note in the photo below that one of the flimsy supports was crushed and bent during shipment.

In contrast, the supports on our SoLuna basic farmhouse sinks are TIG welded with copper rod along the entire length of the support where it attaches to the apron and to the well of the sink. SoLuna sinks not only display superior craftsmanship, they are also sturdier and very solid feeling—the result is a sink built to last a lifetime.

We also offer our exclusive Fernanda farmhouse sink which includes these important features:

  • The Fernanda sink is closed on the bottom and sides of the apron. While giving the sink a more finished look, it creates an increased solidity and substantial feel to the sink. Closing off the bottom of the apron prevents small hands from going up inside and provides a finished look if the apron front is installed extended out from the cabinet.
  • The Fernanda sink also features an X pattern in the bottom of the well---this helps facilitate drainage and gives the sink a distinctive look.



Hammer Pattern

The purpose for hammering a copper sink is to both harden the copper and to give the metal its unique hand crafted appearance. The big box sink has skimped in this area as well providing fewer and shallower hammer pits on the sink. Here are some close-ups of the big box sinks we sampled.

Our SoLuna artisans have developed a unique tighter hammering pattern that produces not only a harder surface sink, but also an appealing look that is not to be found elsewhere.  Here is the look that you can expect from Soluna and our masterful artisans:

The big box sink patina finish is not applied in the same way as our SoLuna sinks, made by 2nd and 3rd generation copper artisans with years of experience applying this technique. We noticed while examining the big box Indian made sinks, that some of the finish rubbed off in several places even while handling it gently. Over the course of time and normal wear and tear, you can expect that the appearance of these sink will not hold up. The result is a very shabby appearance.

SoLuna copper sinks are offered in the four unique finishes as shown below: Dark Smoke, Rio Grande, Café Natural and Matte Copper. These finishes have been developed and applied to the sinks by the Santa Clara artisans in a method passed down through generations. Not only are SoLuna copper sink finishes deeper, richer and more luxurious, they do not rub off--and are virtually maintenance free. For basic cleaning simply use mild soap and water – other cleaners are not necessary.
