What were roman bath houses like?
Yes, that is a real Roman bath, you can still see it if you go to Bath, in England. It is filled with natural hot water that bubbles up from a spring underground, it flows in one end and drains out the other, so there is a constant flow of water through the bath. In my encyclopedia of the roman empire it says: “The baths of the Roman empire were one of the most common typse of building and came to represent luxury, community, recreation and, in the provinces, an assocation with Rome. Any city aspiring to greatness would have possessed baths (or thermae). The baths first appeared in the Italian region of Campania, and the best preserved examples of the early type are in Pompeii. Any large bath consisted of a number of rooms; the apodyterium (the changing room), frigidarium (cold room), tepidarium (warm room), caldarium (hot room) laconicum (dry sweating room) and an area for swimming, a natatio. Heat was provided to the caldarium from braziers or with ducts and hypocausts or underfloor
