Pl.: Sudatoria

A sweat room in a Roman-style bathhouse. It was derived from the verb sudare (to sweat). In modern research, sudatorium is used for a room with a hypocaust and wall heating, heated by its own furnace(s). It is often located between the tepidarium and the caldarium. In this room, the bathers sat on benches where they sweated out what was thought as bad bodily fluids. Sudatoria were rarely fitted with a pool.
