The dispensing chamber of the steamhead is mounted between the studs within the wall of a steam bath enclosure. The chamber is isolated from the environment and includes an elongated steam outlet extending outwardly from the chamber, through an opening in the wall. The rectangular outer edge of the outlet is flush with the interior surface of the wall and is the only portion of the chamber visible from inside the enclosure. The outer edge of the outlet is shaped to coordinate with the appearance of a linear drain. It also allows the steam to be dispensed over a wider area. The outlet has a steam flow capacity greater than the steam flow capacity of the inlet such that steam expands within the chamber as the velocity of the steam is reduced. Internal baffles reduce noise. Light sources may be associated with the chamber.
