The bathhouse is composed of three main chambers with vaulted ceilings. The largest one stretches from the western side in a north-south direction. Additionally, during excavation work in 2017-2018 AD, a water pool was uncovered on the northern end of the bathhouse, extending into the hall on the northeastern side. This pool is encircled by porticoes supported by Corinthian-style columns, where various architectural elements such as columns, capitals, horizontal elements, and statues were found.
This is the largest landmark in the ancient city and the only major
building from the Roman period to have been erected on the eastern
bank of the wadi. It lies between the outlets of the two ancient
bridges spanning the Chrysorhoas River. The baths were deliberately
built close to the important Ain Qairawan spring.
