In todays modern bathroom, steam showers are relatively easy to install or retrofit into the space. A steam shower is, in basic terms, a small, enclosed shower space, with a steam generator where water is brought to a boil and the vapor is released into the stall. The generators are connected to the buildings plumbing and can be installed up to 25 feet away from the shower itself. The power of the generator is based on the size of the space it is servicing and should provide a temperature control to avoid burning. Modular units are available that can be retrofitted in an existing bathroom with minimal construction, replacing a standard bathtub. These units are generally fabricated from acrylic and include the steam mechanism, vapor-lock door and shower heads. Some even come with a jet tub feature as well. Acquinox and Amerec both make these types of units. A custom steam shower is designed when the bathroom is built and is finished with stone or tile walls, floors and ceilings which should be mortar based, not drywall mounted. Doors are fully sealed to retain the steam. There are many amenities available such as rain shower showerheads and massaging jets. At the super deluxe end are steam suites, which can accommodate from two to ten people and include aromatherapy, jets for all body parts, media hookups for entertainment, and mood lighting.
