Copper Tubs Jetted and Non-Jetted

What You Need to Know About Copper Bathtubs

Can copper bathtubs be used inside and outside?

The simple answer is yes. However, copper surfaces will react to environmental conditions.

How do you protect copper surfaces in varying conditions?

Applying lacquer to a copper finish is not recommended because it is unreliable over time. Both inside and outside the home, copper expands and contracts with temperature shifts. This movement destabilizes lacquer coatings, leading to cracking and peeling. Furthermore, lacquer does not adhere well to highly polished metal surfaces, as polish residue and smooth textures eliminate grip. Once it begins to peel, the tub becomes difficult to restore.

What options are available for copper care?

Raw copper surfaces naturally patina when exposed to air and liquids. To slow this process, apply a natural beeswax or similar wax to the surface. While wax does not stop patina entirely, it offers protection for several months before requiring reapplication, depending on usage and environment.

What other precautions help protect the surface?

Drying the tub with a soft cloth or towel after each use is essential. Standing water causes visible spots, whereas dry copper patinas much more slowly.

Unlacquered polished surfaces are easier to maintain than most people expect.

If water spots or marks occur, a drop of copper polish on a microfiber cloth will bring it back to a bright shine within minutes. The newly polished spot may initially look brighter than surrounding areas, but it will oxidize within a few days to blend in.

For dark, aged finishes, further patina development often goes unnoticed.

Unwanted marks on aged copper can be gently buffed out using an ultra-fine Scotch-Brite pad or polished and left to blend naturally over time. If you use a Scotch-Brite pad, wear a dust mask to avoid inhaling copper dust.

Maintaining a copper tub in a nutshell.

If you want to enjoy the benefits of bathing in a solid copper tub, expect to put in minimal ongoing care to protect your investment. With proper maintenance, a copper bathtub will last a lifetime.

Are there low-maintenance options?

Many manufacturers offer copper tubs with enameled interiors, eliminating the need to dry the basin after use. We have tested and found that high-heat enamel can readily show light scratch marks even during polishing. If chipped or heavily scratched, enamel repairs are difficult and require professional service.

Hybrid tubs are another alternative.

Featuring a copper exterior skirt with an acrylic or cast-iron porcelain inner basin. These interior shells are easy to clean and highly scratch-resistant. Homeowners can easily repair minor scratches on acrylic, whereas porcelain on cast iron requires professional restoration.

The drawback of enameled and hybrid tubs.

The loss of copper’s natural antibacterial surface inside the basin. The trade-off is visual appeal without the requirement to dry the tub after every bath.

Additional factors for outdoor copper tubs

• Direct sunlight causes copper to heat quickly, making it too hot to touch. Overhead shading helps mitigate heat buildup.
• Outdoor exposure accelerates the patina process significantly.

What to expect when allowing your copper tub to age naturally.

Allowing copper to age produces a unique, evolving finish. Coastal environments often bring out verdigris greens, blues, and subtle purple hues. Rural setting environments develop deep brown and bronze tones. Every tub reflects its environment, ensuring a unique finish over time.
