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.
