{{Short description|Vaulted sweating-room in a Roman bath}} In [[architecture]], a '''sudatorium''' is a vaulted sweating-room (''[[:wikt:sudor#Latin|sudor]]'', "sweat") or steam bath (Latin: ''sudationes'', steam) of the Roman baths or [[thermae]]. The Roman architectural writer [[Vitruvius]] (v. 2) refers to it as ''concamerata sudatio''.<ref name=EB1911>{{1911|wstitle=Sudatorium|volume=26|page=19|inline=1}}</ref> It is similar to a ''[[laconicum]]'', or dry heat bath, with the addition of water to produce steam.
In order to obtain the great heat required, the whole wall was lined with vertical [[terracotta]] [[flue]] pipes of rectangular section, placed side by side, through which hot air and smoke from the [[suspensura]] passed to an exit in the roof.<ref name=EB1911/>
When Arabs and Turks overran the [[Eastern Roman Empire]], they adopted and developed this feature in their baths or [[Turkish bath|hammams]].
