Custom Copper Sinks: Aerospace-Grade Craftsmanship Handcrafted in the USA
"Our welding isn't just professional; it's unprecedented."
After inspecting our shop, master welders from NASA and Blue Origin stated they had never seen this level of precision outside of the aerospace industry. You are commissioning a piece of American engineering designed to last generations.
Engineering vs. Aesthetics: Why Rachiele® Stands Alone
Investing in top-tier materials isn’t just about aesthetics—it’s about durability, performance, and a lifetime of reliability.
Why Cold-Rolled Matters
When comparing sinks, most people look at the gauge (thickness), but the Yield Strength is what actually protects your investment. While tensile strength tells you how much force it takes to tear the metal, Yield Strength tells you how much force it takes to permanently dent it. Because Rachiele uses cold-rolled copper with a yield strength over 3.5 times higher than the soft, annealed copper found in imports, our sinks can withstand the accidental impact of a heavy cast-iron skillet or a dropped pot that would leave a permanent 'battle scar' in a softer sink.
This superior structural integrity is why master welders from NASA and Blue Origin recognized our work as aerospace-grade.
-
Rockwell Hardness: Cold Rolled is ~80% Harder than Annealed (~80 HRF vs ~45 HRF).
-
Tensile Strength: Cold Rolled is ~31% Stronger (~42,000 psi vs ~32,000 psi).
-
Yield Strength (Dent Resistance): Cold Rolled is ~260% More Dent Resistant (~36,000 psi vs ~10,000 psi).

What you see is our 22 year old copper sink. Maintaining your copper sink’s beauty is easy. Simply rinse after use and avoid leaving items in the basin. While items left in the sink may temporarily affect the patina, this natural patina is designed to evolve over time, telling a unique story through its subtle changes. The patina’s transformation adds character, enhancing the sink's distinct and beautiful look.
Natural Aging vs. Artificial Finishes Imported sinks often feature "artificial" patinas that offer chemically forced colors, will never return to the original look after use. Rachiele sinks feature proprietary natural patinas. Our process allows the copper to develop a rich, deep finish that is "living"... It heals itself if scratched and grows more beautiful with age.
Rinse & Go: No Obsessive Drying Required
Most manufacturers require you to "wipe the sink dry" after every use to prevent spotting or finish damage. That is a chore, not a feature. Because of our superior cold-rolled copper and natural finishes, along with the engineered proper drainage, Rachiele care is effortless. Simply rinse after use and wash with standard dish soap. No specialized waxes or constant drying are ever necessary.
I love your sinks because they are EASY to take care of (yes- I am lazy). I used to have a stainless steel sink in my kitchen, and the smudge marks used to drive me crazy. I really don't do much to keep my sinks looking beautiful now- I simply rinse them out with soap and water while washing my dishes. Nothing else!!!!" Jessie
Paint" with ketchup and a paint brush, and the patina temporarily vanishes. The sink will re-patina over the next several days simply by using the sink. The speed in which the sink will re-patina has a bit to do with how much you use the sink and what type of water you have. The more minerals in the water, the faster it will change. You truly cannot permanently damage the interior of our copper sinks.
Our copper sinks are crafted to combine beauty with exceptional functionality. Each sink includes an option for a ledge designed to support a half-sheet pan, freeing up valuable counter space during meal prep. With this feature, your countertops may feel almost obsolete; just give them a quick dusting and let your sink handle the heavy lifting.
Even a deep, intentional cut vanishes in just a few weeks in the bowl of our copper sink. The middle photo is after two weeks, and the bottom photo is after 4 weeks. The cut is still in the copper. However, the "self healing" properties of the copper act as camouflage. You never have to worry! I did this to a working sink in our showroom.
Lifetime Assurance
We offer a Lifetime Transferable Warranty on our copper sinks. Furthermore, we provide a unique "Thrilled Customer Guarantee": If you aren't completely thrilled upon delivery and inspection, we will refund your money, pay for return shipping, and send you a $500 check for the inconvenience.

Designing for the Moments That Matter
Families don’t drift apart all at once. Life simply moves quickly. Meals come and go. Cleanup happens. The kitchen empties sooner than anyone expects.
I wanted to create a different rhythm. One where the kitchen invites people to stay. Where hands work together naturally. Where conversations continue, even as the evening winds down.
Nothing about the family needs to change.
The moments just have more room to last.
That’s the work I care about.
This is what I hope to bring to your home.
New Copper Sink Advice From Past Customer
"Dino Rachiele forwarded an email you'd written regarding your new sink and asked if I would contact you. I purchased two copper sinks and have been using them daily since 2012.
I read your email and saw the picture that you'd sent Dino and wanted to share my thoughts. The first thing I thought when I saw the picture was that your sink looked brand new and hadn't had a chance to develop the patina that will come with use. When my sinks first arrived, like yours, they were a uniform color. When I first started using them, the very first marks (reactions to the copper) stood out in stark relief against that uniform color. They were very noticeable, and your eye can't help but go right to them. You said in your email that you aren't even using the sink like you will be once you're cooking and entertaining. Once you start really using it, the sink will have a lovely, varied finish. You won't have that one mark that stands out like you do now.
The beauty of the sinks really comes out as you have lots and lots of marks that are made and then fade and change. You'll have layers of overlapping reactions that will create a gorgeous patina." Linda White
Copper Sink Pros and Cons
Copper is not only stunning but also highly functional in the kitchen. Thanks to its excellent heat conductivity, copper can speed up the thawing process—just place frozen food directly on the surface and watch it defrost quickly. In this comparison test, ice melted in just 6 minutes on the copper versus 46 minutes on stainless steel! Beyond heat conduction, copper boasts impressive antimicrobial properties, naturally reducing bacteria on its surface. This makes it an ideal choice for a hygienic, efficient, and beautiful kitchen workspace
At less than a year old, this imported copper sink has already lost its beauty due to its unnatural finish. Unlike naturally weathered copper, which develops a rich patina over time, these sinks often discolor permanently from water pooling, especially with flat bottoms. Copper naturally ages to a beautiful, old-penny color, but many imports require drying after each use to prevent unsightly blemishes. Our sinks are designed to avoid these issues, ensuring a durable, authentic patina that enhances their beauty with time
Hammering adds a captivating, artisanal beauty to each sink, creating a rich texture that catches and reflects light in unique ways. This hand-hammered finish brings out copper’s natural warmth, giving the sink a distinctive character that enhances any kitchen style. Each mark tells a story of skilled craftsmanship, adding depth and individuality to the sink’s appearance. For those who value both aesthetic and authenticity, the hand-hammered look offers a timeless elegance that transforms a functional piece into a true centerpiece.
The Aftermath...
Being Italian, we eat our salad last. After a large dinner, our well-meaning guests kindly helped load the dishwasher but didn’t rinse the sink. Bits of salad and vinegar were left behind for several hours.
Most of our customers actually love this; by the next day, their sink would display stunning new patterns in the patina. I, on the other hand, tend to prefer a more uniform look. So I occasionally strip most of the bottom patina, just to show how effortlessly it can be renewed. It's part of the beauty of copper: a living finish that evolves or resets on your terms.
To refresh the patina, I simply used the sponge shown in the photo—Scotch-Brite side down—and scrub the bottom of the sink using only warm water. Within minutes, most of the patina lifts away. You may notice some fine scratches at first, but by the following day, they’re typically all but invisible as the copper begins to re-patina naturally.
Important: I recommend removing only the patina on the bottom of the sink. The sides don’t receive enough daily contact to regenerate quickly, and attempting to strip them may result in uneven coloration that lingers. Let the sides age gracefully—while the base remains easy to refresh as needed.
Watch How Effortless It Is.
This video shows just how simple it is to refresh the bottom of one of our copper sinks using a Scotch-Brite pad. It took me only 60 seconds in our 24" sink.
For many new Rachiele® copper sink owners, the first few months can feel like uncharted territory—they often treat the sink with delicate caution. But once they begin using it freely and see how remarkably resilient it is, confidence grows. That shift changes everything. They stop worrying, start enjoying, and come to appreciate what this sink truly is: a hardworking showpiece that gets even more beautiful with time.
