A steambath is an ancient type of bath, first made popular by the ancient Greeks and Romans. The origins of the steam bath come from the Roman bath, which began during the height of the Roman Empire. Ancient Roman baths served many community and social functions within Roman society. Everyone in Rome used Roman public baths, regardless of socioeconomic status. These Roman baths were supplied by natural hot springs from beneath the ground.
Today, natural steam baths still exist, and often still use similar systems that the Romans used, which contain pipes and pumps that bring water up and into the large pool areas, wherever the natural springs exist. Heaters are also now used to maintain warm temperatures in the baths.
There are many different types of steam baths, which are different from a sauna. (In the sauna, the air temperature is high but relative air humidity is low, whereas in a steam bath air humidity reaches 100 °C (212 °F) while air temperature is lower (40-45 °C/104-113 °F) compared to the sauna.)
