Description
An undermount sink disappears below the counter, so what remains is the material. The Hammered Under is a solid copper undermount basin: the hammered texture shows along the front edge below a stone, quartz or concrete countertop, and the interior is smooth and easy to clean.
Copper develops a living patina that deepens and warms with use. At 6 inches deep, it is sized for bathroom vanities, powder rooms and bar or prep sinks.
- Sizes: 12 x 10 x 6, 14 x 12 x 6, or 16 x 12 x 6 inches
- Installation: undermount
- Material: solid copper, hammered exterior, smooth interior
- Care: rinse and dry; avoid bleach and abrasive cleaners
Need a deeper basin or a full kitchen size? See The Ember Copper Sink, available up to 36 inches. Pair it with polished copper or unlacquered brass faucets.

Questions & Answers
Everything you need to know
Does Brassna brass change color over time?
Unlacquered brass and copper are living finishes: they develop a warm patina as they react to air, water and daily use, and deepen in character over the years. Prefer a tone that stays put? Choose Brushed Brass, Brushed Nickel or Polished Nickel, which hold their original look.
How do I care for my Brassna fixtures?
Wipe with a soft cloth, warm water and a drop of mild dish soap, then dry to prevent water spots. Avoid bleach, ammonia and abrasive cleaners. No special kits required.
Can I keep the bright, golden shine?
Yes. To restore the original luster on unlacquered brass, polish gently with a quality brass polish or a lemon-and-baking-soda paste, then rinse and dry. Polishing simply resets the surface, and the patina returns naturally over time. A thin coat of carnauba wax slows the aging.
Will every piece match perfectly?
Pieces in the same finish are made to match. Living finishes such as Unlacquered Brass and copper patina at their own pace depending on use and water, so tones can drift slightly over time. For a project, order all pieces in the same finish at the same time for the closest match.
Is it really solid brass?
Yes. Every Brassna faucet and fixture body is solid brass, not zinc or plastic. Our brass finishes are never plated. Our nickel finishes are a nickel finish over the solid brass body. Our bathtubs and copper sinks are made from solid copper.
Will Brassna fixtures fit standard US plumbing?
Yes. Our faucets install like any premium fixture, using standard US connections. We recommend installation by a licensed plumber.
How long does shipping take, and what does it cost?
Shipping is free via fully tracked DHL or UPS express. Delivery to the United States typically takes 3–5 business days once your order ships. Made-to-order and custom pieces can take longer, and we always confirm timing before you order.
What is your return policy?
We offer a 60-day return policy. If a piece is not right for your space, return it within 60 days for a refund or exchange. See our return policy for details.
Are Brassna fixtures under warranty?
Yes. Every fixture carries a Limited Lifetime Warranty on the solid brass body, and 5 years on parts and finish.
Do you offer custom orders and a trade program?
Yes. We make custom pieces and finishes on request, and our Trade Program offers dedicated pricing and support for designers, architects and builders.
