A steam bath is a holistic health treatment, geared toward extracting impurities from the body using heat. It differs from a sauna, in that its effect is brought about by the use of wet heat as opposed to dry. The ceiling of a steam room is intentionally made to a point that allows condensed moisture to flow down the walls instead of dripping onto patrons. Traditionally, steam room walls have been constructed using some type of ceramic or stone. However, the porous nature of these materials provides a breeding ground for bacteria, mildew, mold and various parasitic organisms. For this reason, hybrid models have been developed. The hybrids are fashioned from less permeable materials, and can self-sanitize at the end of each day.
