A glass door built later on the west façade provides access to the rectangular bath building. The first part is the “changing room,” which has completely lost its original form. A door on the east wall of the changing room leads to the room. The lukewarm room has a central and two lateral sections, all domed. A door on the east wall of the central section leads to the “hot” room, which consists of a dome-covered central main space, three iwans, and private rooms in the corners. The lateral iwans are covered with pointed barrel vaults; the iwan opposite the door of the hot room is covered with a dome.
