Choose Your Finish

Brass or Copper - Two Living Finishes, One Artisan Form

Both are handcrafted to the same exacting standard in Marrakesh. The difference is in character: brass ages into warm golden amber tones; copper evolves into deep, reddish antique hues. Neither is lacquered, both tell your story.

Solid unlacquered brass polished undermount sink — golden warm tone, kitchen island installation

Solid Brass · 19-Gauge

Warm Golden Radiance

Starts with a bright golden sheen, deepening over time into amber and honey tones. 19-gauge thickness means edges that won't bend even under daily heavy use.

Unlacquered Brass → Ages to amber patina
Solid unlacquered copper polished undermount sink — rich reddish tone, outdoor kitchen installation

Solid Copper · 16-Gauge

Rich Antique Depth

A deep reddish-orange that evolves into rich bronze and dark antique tones. 16-gauge, extra thick, built for outdoor kitchens, island bars, and heavy-duty prep use.

Unlacquered Copper → Ages to antique bronze

Both finishes develop a living patina over time. This natural aging is expected, celebrated, and never considered a defect.

Why Choose Artisan-Crafted Over Mass-Produced?

Not all metal sinks are equal. Here's how our handcrafted undermount sinks compare to what you'll find at big-box retailers.

Attribute Our Polished Sink (Brass or Copper) Mass-Produced Alternatives
Material ✓ 100% solid brass (19-gauge) or solid copper (16-gauge) — through and through ✗ Brass-plated zinc or thin stainless steel — corrodes within 3–5 years
Finish ✓ Unlacquered living finish — ages into a unique patina. No coating to peel or chip ✗ Lacquered or powder-coated — chips over time, cannot be restored
Craftsmanship ✓ Hand-polished by master artisans in Marrakesh, Morocco. Each piece is unique ✗ Machine-stamped in bulk — no texture variation, no artisan involvement
Thickness & Feel ✓ 16–19 gauge solid metal — edges will not bend or warp under heavy use ✗ 20–22 gauge or thinner — edges flex and dent, seal gaps common
Corner Integrity ✓ Double-sealed corners — reinforced against cracking and water seepage ✗ Single-seam — known failure point, frequently requires re-caulking
Lifespan ✓ 20+ years with normal care. Solid metal improves in character over time ✗ 5–8 years before degradation is visible — finish and structure both suffer
Warranty ✓ 5-Year limited warranty on materials and workmanship ✗ 1 year limited — rarely honored without extensive documentation
Customization ✓ Custom sizes, depths, and finishes available on request ✗ Fixed SKUs only — no adjustments for your countertop cutout

Why This Sink Is Worth The Investment

Moroccan artisan hand-polishing brass sink in Marrakesh factory workshop

Forged by Moroccan Master Artisans

Every sink begins as a flat sheet of solid metal in our small Marrakesh factory, where local artisans with decades of metalworking experience shape it entirely by hand. The polishing technique isn't just decorative — it ensures a smooth, flawless surface that captures light beautifully in any kitchen. Factory-made alternatives simply cannot replicate this level of care. Each piece is one of a kind, crafted with passion.

Solid Metal All The Way Through — Not The Average Thin Brass

Mass-produced sinks use brass-plated zinc or thin 20-gauge stainless that flexes and dents. Our brass is 19-gauge solid throughout; our copper is an even thicker 16-gauge — heavy duty, built for outdoor kitchens, island prep stations, and daily heavy use. Because the metal is thick, the edges won't bend during installation, ensuring a perfect fit without having to reshape the sink.

A Living Finish That Becomes More Beautiful With Age

Unlacquered metal is raw — no chemical barrier separates it from its environment. Brass deepens from bright gold through warm amber into honeyed antique tones. Copper journeys from vibrant reddish-orange into rich bronze and dark, storied hues. This isn't wear — it's character. It's your home's history written into metal. Every other sink in your kitchen will look the same in ten years. This one will look better.

Precision-Built for Undermount Installation

Double-sealed corners prevent cracking and water seepage — the most common failure point in any metal sink. Compatible with standard US 1.5" and 2" drain openings, and designed for seamless undermount installation. Outdoor use is fully supported: both brass and copper are highly resistant to corrosion and weathering, and the natural patina actually protects the metal over time. Installs in under 15 minutes.

Frequently Asked Questions

Is this worth the investment compared to cheaper alternatives?

Absolutely. Mass-produced alternatives use brass-plated zinc that degrades within 3–5 years, with coatings that chip and cannot be restored. Our solid brass (19-gauge) and solid copper (16-gauge) sinks are built to last 20+ years and actually improve in character as they age. You're not buying a fixture — you're investing in a piece of Moroccan craftsmanship that will outlast every trend in your kitchen. Most customers tell us it's the best home upgrade they've ever made.

What's the difference between brass and copper — which should I choose?

Both are solid, unlacquered, and hand-polished by the same Moroccan artisans. The difference is in the aging journey. Brass begins with a warm golden tone and deepens over time into rich amber and antique honey hues — elegant and timeless. Copper starts with a vibrant reddish-orange and evolves into deep bronze and dark antique tones — more dramatic and storied. Copper (16-gauge) is also slightly thicker, making it the preferred choice for outdoor bars or heavy-duty outdoor kitchens. Both are equally beautiful and durable.

How does the unlacquered living finish develop — and is it a flaw?

Not at all — it's the most celebrated feature of these sinks. Unlacquered metal is raw, with no chemical barrier separating it from air and moisture. Over weeks and months, the surface oxidizes naturally, darkening and shifting in tone in a pattern that's entirely shaped by your environment and how you use your sink. No two patinas ever look the same. This aging is expected, intentional, and explicitly not considered a defect under our warranty. If you prefer a brighter look, an occasional polish with a brass- or copper-specific product will restore the original shine.

Is this sink suitable for outdoor use?

Yes — both solid brass and solid copper are highly resistant to corrosion and weathering. In fact, the natural patina that forms actually serves as a protective layer, slowing further oxidation over time. These sinks are ideal for outdoor kitchens, bar areas, and prep stations. The 16-gauge copper is especially popular for outdoor use given its extra thickness. Just rinse after use and wipe dry for best longevity.

How do I care for my brass or copper sink?

Rinse after use and wipe dry — that's the core routine. For cleaning, use mild soap and warm water. Avoid abrasive cleaners, bleach, or acidic substances (vinegar, lemon juice) as these will accelerate patina development unevenly. If you want to maintain the original shine, occasional polishing with a brass- or copper-specific product will restore it. If you prefer to embrace the patina, simply let it develop naturally — it only gets more beautiful.

What if I'm not satisfied or need a different size?

We accept returns within 30 days of delivery for unused items in their original packaging.

      Shipping to the US and has been in FEDEX customs for five weeks. Insideast customer service has been responsive with responding to emails but there is nothing they can do. I have ordered from them before and it took several weeks but not this long. We have not been able to install the other faucet we ordered but it’s heavy and looks nice.
