Adapting specialized metal bonding technology, Penhaglion prepares and coats the tub exterior surfaces in the material of choice before presenting it in a light random brushed finish, ready to patinate. What form the patina takes depends solely on the environment inside the room, but whatever occurs, it is certain to be beautiful, unique and totally natural.

Unless a buyer prefers to retain the original or specific appearance on the metal, there is absolutely no maintenance required to allow these tub exteriors to flourish. Should only minimal exterior patination be an owners preference, the surface can be coated with natural beeswax to slow or prevent further patina formation.

These natural color and surface changes can vary in time from slow to quite fast. Most often however, the effects of the oxidization or tarnishing are not visually noticeable on a day to day basis. However, while nothing may be apparent to the naked eye, the patina will be developing. Should some individual markings not be to an owners liking, it is a small task to remove these and allow the finish to resurface.
