Which room in the Thermae was the hot room?

• A. Caldarium
• B. Tepidarium
• C. Sudatorium
• D. Unctuaria

Answer: (A)

In Roman bath architecture, the hot room is the caldarium. This space was heated to a high temperature by the hypocaust, and it housed a hot bath that defined its purpose as the hottest part of the complex. The tepidarium was a warmer, intermediate space for acclimating to heat, the sudatorium served as a sweating or steam room, and the unctuaria was where oil was applied after washing. So the caldarium stands out as the hot room because its defining feature is the intense heat and hot bath it contains.
