Copper is a naturally anti-microbial metal that develops a beautiful living finish patina over time. This bathtub is destined to become more beautiful with age.

The drain is centered, but adjustments to drain placement can be made, please call for more information. No overflow or faucet holes. For a quicker filling, we recommend using 2 (two) tub fillers. We suggest insulating the double walls with marine foam to ensure longer and warmer bath times.

Maintenance Tips SoLuna Finishes:

Wiping your SoLuna copper product down with a soft rag and spot checking with soap and water is generally all the cleaning your SoLuna copper product will ever need. We recommend NOT using anything abrasive for bathing or cleaning, including products like bleach, bristle brushes, and harsh soaps.

To keep your copper sink or bathtub in premium condition, we recommend routinely waxing your sink or tub with Renaissance Wax or Howard Wax-It-All.

Please note: Some Copper Products offer the option for the application of a lacquer seal to protect the original patina. Wax is not necessary to maintain the finish of lacquered copper products. However, waxing does provide an extra layer of protection from dirt and grease for both lacquered and unlacquered copper products.
