Considering the Hotel Mas de Peint in Arles?

Baths of Constantine by Tom_Fields
These baths offer a look at how the Romans bathed, which they generally did daily whenever possible. The baths were a center of social life, where people gather and talk about the day. There were three main parts: the tepidarium, the caldarium, and the frigidarium. The first was lukewarm, the second hot, and the third cold. Bathers would enter them in that order. Then they would dry off. Slaves kept the fires burning to heat up the water. One can still see where they would toil, constantly moving new coals into the cavities beneath the water and sweeping out the ashes.
