A copper bathroom sink can add style, functionality, and luxury to any bathroom. Copper sinks have experienced a surge in popularity in recent years as homeowners seek to incorporate beautiful, natural materials into their homes. In this comprehensive guide, we will explore everything you need to know about copper bathroom sinks, from styles and installation to cleaning and maintenance.

An Introduction to Copper Bathroom Sinks

Copper has been used for centuries in cooking, architecture, and decorative arts. While stainless steel and porcelain remain the most common sink materials, copper brings an old-world, artisanal feel that stainless cannot match. The soft glow and patina of copper develop naturally over time, making each sink truly unique.

Copper sinks work well in a range of bathroom styles, from traditional to modern. A classic apron-front copper farmhouse sink suits a cottage or farmhouse bathroom. Sleek copper vessel sinks can elevate contemporary vanities. Curving copper sinks complement bathrooms with organic shapes and textures.

Beyond aesthetics, copper offers practical advantages. The antimicrobial properties of copper make it hygienic while the malleability allows for creative designs not possible with other materials. While porcelain and fireclay can chip or crack, copper is extremely durable. With proper care, a copper sink will last a lifetime.

Styles of Copper Bathroom Sinks

Copper bathroom sinks come in a diverse array of shapes and mounting styles. The finish, color variations, and hammered or smooth textures allow for numerous custom looks. Here are some of the most popular styles of copper sinks for bathrooms:

Vessel Sinks

Vessel sinks sit on top of the vanity counter, rather than being mounted under the counter. Their free-standing design makes a dramatic style statement. Copper vessel sinks come in round, square, rectangular, and oval shapes. Their height allows you to fill the deep basin without splashing water onto the counter.

Drop-In Sinks

Drop-in, or self-rimming, sinks fit into a pre-cut hole in the countertop. The rim of the sink extends slightly over the countertop edge. Caulking or sealant around the rim prevents water from getting under the countertop. Drop-in sinks come in round, oval, or rectangular shapes.

Undermount Sinks

Undermount sinks attach below the countertop, creating a sleek, contemporary look. The countertop extends past the sink rim for easy wipe-down after washing. Undermount installation is more difficult than drop-in but achieves a seamless transition from countertop to sink.

Apron-Front Sinks

Apron-front, or farmhouse, sinks fit into a front-facing cabinet rather than under the countertop. The signature exposed front panel or “apron” acts as a built-in backsplash. Apron-front copper sinks suit traditional, farmhouse, and rustic bathroom styles.

Hammered Copper

Many copper bathroom sinks feature a hammered finish. Hammering the copper by hand creates dips and indentations in the surface. The hammered look adds artisanal appeal and can help conceal water spots. The variations in the metal reflect light beautifully.

Smooth Copper

Smooth copper sinks have a consistent, glossy surface without any indentations. While generally more expensive, the smooth finish achieves a refined, mirrored look when polished. Over time, smooth copper will also develop a patina but in a more uniform pattern.

Benefits of a Copper Sink

Beyond the stylish aesthetics, copper bathroom sinks provide many benefits that make them a smart and functional choice:

Antimicrobial Properties

Copper naturally kills bacteria, viruses, and fungi on contact. Research shows copper has an intrinsic ability to kill superbugs like MRSA. This antimicrobial quality makes copper an ideal, hygienic material for sinks.


Copper has incredible durability and strength. Copper sinks will not chip, crack, or stain like porcelain. While scratches are possible, they lend character. With proper care, copper will last a lifetime without losing structural integrity.

Heat Absorption

Copper quickly absorbs and distributes heat. The material warms up rapidly under hot water. The retained heat keeps drain water warmer, preventing P-trap freezing in winter.

Sound Absorption

In addition to heat, copper absorbs sound. The dense material does not amplify noise from running water. Copper sinks remain quieter than most other sink materials.


A high-end copper sink elevates the whole bathroom. The artistry and natural beauty of copper boost the value of the room. The antibacterial properties also help maintain a sanitary environment.

Considerations When Choosing a Copper Bathroom Sink

With so many styles and variations available, keep the following considerations in mind when selecting your copper bathroom sink:


Measure your existing sink or vanity countertop carefully to ensure your new sink will fit the space. Copper sinks come in standard round sizes, rectangular lengths, and other custom dimensions.

Mounting Style

Determine if you want an undermount, vessel, or apron-front copper sink. The mounting style affects installation requirements. Check that your countertop material and vanity can support the weight.


Copper is dense and heavy. Make sure the vanity cabinet and brackets are rated to bear the load of a full copper sink, which can weigh 75 pounds or more.

Drain Placement

Drain placement varies between sink styles. Make sure the drain hole location will align with your existing plumbing. Custom copper sinks can be made with personalized drain positions.


Consider whether a hammered or smooth finish better suits your bathroom’s decor. While both develop patina, hammered copper shows wear less over time.

Tap Holes

Decide if you want pre-drilled tap holes or no holes at all. Holes can be added later but covering unneeded holes is difficult. Minimal hole sinks maximize design flexibility.


Copper sinks span a wide price range. Set a budget to narrow down styles within reach. Prioritize sink size and design over finish and branding.

Lead Content

Ensure any copper sink is certified lead-free. Lead-tin alloyed copper can leach lead over time. Lead-free copper (less than 0.25% lead) is safe but verify before purchasing.


Look for copper tagged as recycled or reclaimed. New copper mining has environmental impacts. Reusing copper reduces the need for additional mining.

Installing a Copper Bathroom Sink

Installing a copper bathroom sink requires careful planning and precision. Here are some tips for proper installation:

Gather Supplies

Copper safe cleaners, silicone adhesive, basin wrench, plumber’s putty, PTFE thread seal tape, copper braided supply lines, Rags, Eye protection.

Prepare the Countertop

Cut the countertop hole (drop-in) or remove section (undermount) to fit sink. Cover exposed edges with silicone.

Position the Sink

Set sink in place. Have a helper hold it in correct position until fastened.

Mount and Seal

Attach mounting clips, brackets, or screws through pre-drilled sink holes. Seal between sink and countertop with silicone.

Connect Drain

Apply plumber’s putty around drain hole. Thread drain assembly through the sink and into drain pipe. Tighten by hand first and then with basin wrench.

Connect Water Supply

Use PTFE tape on water line threads. Attach flexible braided copper supply lines to water supply valve and sink faucet.

Check for Leaks

Turn on water supply and test for leaks at drain and supply line connections. Tighten joints as needed to stop any drips.

Finalize Installation

Run water into sink and check alignment and function. Reseal around sink with a thin bead of silicone once more.

Caring for a Copper Sink

Like any natural material, copper requires some simple maintenance to keep it beautiful. Avoid abrasive cleaners or pads that could scratch the finish. Here are some tips for caring for a copper sink:

Daily Cleaning

Use soft sponges or cloths with mild soap and warm water to clean. Rinse and dry thoroughly after each use.

Weekly Polish

Apply a thin layer of copper polish cream weekly. Buff off residue with a soft cloth. Frequent polishing maintains the patina.

Remove Water Spots

Soak a cloth in a solution of lemon juice and salt. Gently rub water spots to remove discoloration. Rinse.

Address Scratches

Use 220 grit sandpaper to smooth minor scratches, followed by a copper polish to blend. Prevent scratches by using sink grids.

Never Bleach or Ammonia

Do not use any cleaners containing bleach, ammonia, acids, alkalis, or abrasives. Use copper-safe products only.

Dry After Use

Leaving sinks wet leads to water spots and corrosion. Always towel dry your sink after use to keep the surface smooth.

Re-Seal Yearly

Check silicone seals yearly and reapply anywhere gaps appear between sink and countertop.

Frequently Asked Questions About Copper Bathroom Sinks

Does copper turn green?

With time, use, and exposure to water and air, copper develops a natural greenish “patina” coating. This verdigris patina is normal and will not transfer onto hands. Preventing excess moisture helps maintain the color.

Do copper sinks stain?

Copper will not absorb stains like porcelain can. However, copper safe cleaning is essential to prevent corrosion. Avoid letting soap, toothpaste, or makeup residue dry on the sink, as mineral deposits in those products can etch the finish.

How often should I polish a copper sink?

Frequent polishing is key to maintaining the surface sheen and removing water spotting on copper. Polish weekly with a copper cream and soft cloth. For smooth finished copper, polish 2-3 times per week.

Can you use copper sinks with well water?

Copper can interact with the higher sulfur and mineral content in well water. This can accelerate patina formation. Using distilled vinegar rinses can help remove mineral buildup. Consider installing a water softener.

Are copper sinks better than stainless steel?

Copper and stainless both make excellent sink materials. Copper offers a more artisanal, natural look compared to industrial stainless. Copper also has antimicrobial properties while stainless resists corrosion. Both materials are durable choices.

Do copper sinks dent easily?

Denting is not a significant concern with solid copper sinks. Copper is malleable but still resilient against dents with proper use. Avoid dropping heavy objects directly into the sink. Use a sink grid to protect the surface.

Can you solder a copper sink?

Avoid soldering anything onto the copper sink itself. Instead, hire a plumber to solder all joints between supply lines, drains, and available plumbing. Any leaks also require professional re-soldering.

How much do copper sinks weigh?

The weight varies by size but expect a typical medium copper sink to weigh 35-60 lbs. Larger single-bowl farmhouse sinks may weigh over 75 lbs. Make sure plumbing and the vanity can bear the substantial weight before purchasing the sink.

Should I seal my copper sink?

Sealing is not required for copper sinks. Allowing the sink to develop natural patina is ideal. If you wish to inhibit patina and water staining, apply wax sealants designed specifically for sealing copper. Avoid varnishes or polyurethane.
