Access to this rectangular bath building is provided through an entrance passage added later to the northwest façade. The passage leads to a rectangular “changing room” with a flat roof. The “lukewarm room” is beyond a rectangular door on the north wall of the changing room.

There is a hood above the door. The lukewarm (or cold) room has a central section, and two domed lateral units lie beyond the openings with pointed arches. A door with a pointed arch in the middle space connects the lukewarm room to the “hot” room. The hot room features a domed main space in the center surrounded by three iwans and private cells in the north and east corners. Two iwans have pointed barrel vaults; the other iwan and the private rooms are domed. In the middle section, the dome is supported by pendentives decorated with muqarnas.
