Although the central bath of Alabanda has not yet been excavated, one can see the building plan. Like all Hellenistic and Roman baths, it had a frigidarium and a caldarium.

The length of the building in north-east/south-west direction is 69.0 meters. The 43.1 m long and 8.1 m wide apsidal space probably served as an apoditerium. The 17.0 m long and 21.9 m wide central room was connected to the adjacent rooms by arched doors. The large arched entrance was 5.8 m wide and probably 2.5 m high. The smaller of the interiors was 8.9 m x 11.2 m and had a vaulted passage to the central room.

Nothing could be learned about the age of this building. Future excavations and research will certainly also bring information about this to light.
