What does sudatorium mean?
A sudatorium is a room or building in which sweating is induced, traditionally as part of a bathing or therapeutic regimen. The word is most strongly associated with ancient Roman bath complexes, which included specialized rooms where bathers underwent hot-air or steam treatments before cooling themselves in cold pools. In later medical and bathhouse contexts, a sudatorium could similarly serve as a chamber for promoting perspiration. Although the term is precise and evocative, it now sounds chiefly historical and scholarly. In everyday English, “sweating room,” “steam room,” or “sweat bath” are more natural descriptions, depending on the facility’s precise function. The word is therefore especially useful when discussing Roman bathing architecture, the history of medicine, or period descriptions of ancient health practices.

Etymology of sudatorium
Sudatorium is a Latin noun meaning “a sweating place,” formed from sūdāre, “to sweat,” with the suffix -torium, indicating a place or instrument for performing an action. English borrowed the Latin word for a bathing room used to induce perspiration. The same Latin root also underlies related English words such as sudor, sudation, sudatory, and sudorific.
How sudatorium is actually used
This is a rare, largely historical term. Modern speakers normally say “sweating room,” “steam room,” or “sweat bath” instead.
