View looking east at the east wall of the hot room (caldarium) of the women's section of the Stabian Baths. Note the marble-covered hot tub, the tile design on the east wall, the frescos on the sidewalls, along with the stucco pilasters and ceiling.
At the Stabian Baths at Pompeii, the women had their own section with a separate entrance, changing room, hot room, and warm room.
The Stabian Baths were the oldest and largest baths in Pompeii and were constructed in the second century B.C. They included a (un)dressing room (apodyterium), a medium temperature room (tepidarium), a hot room (caldarium), and a cold room (frigidarium). One usually proceeded through the bath in that order. Besides these usual rooms, they included a men's and a women's sections (thus baths), a large open exercise area (palestra), and a swimming pool.
The earthquake of A.D. 62 severely damaged these baths and some areas were not in use at the time of the eruption of Vesuvius.
