| Room D was a tepidarium, room B a sudatorium, later extended with an apse containing a basin. |
| It was said to have been introduced at Rome by Agrippa and was also called sudatorium and assa. |
| In the sudatorium or sweating room of the ancients the body was immersed in heated sand. |
| Through the warm and milky vapours of the sudatorium could be caught glimpses of the red and naked bodies of notable citizens. |
| In the far right hand corner is the laconicum or sudatorium, a circular room which served as a sauna. |
| Were too many ventilators to be placed near the hotter end of the sudatorium, this stream would be diverted. |
