It is thought that Imaret Madrasa was built as a “Palatial Bath” upon the suggestion of the Seljuk Palace. This bath is built with rough-cut stones. The entrance to the east-west-oriented rectangular bath is on the south side. It consists of a rectangular “passage” with a cross-ribbed vault. To its west is a domed “lukewarm room”; to its north is the “hot room” accessed through a door with a pointed arch. The domed space to the west of the passage, which seems to be an extension of this section, functioned as the lukewarm room. The square and domed section north of the passage is the hot room, which can be reached through a door with a pointed arch. There are niches on all the façades of the hot room. The arches of these niches are heart-shaped in the south, pointed in the north, triangular in the east, and trefoil in the west. There is a toilet covered with a pointed barrel vault to the east of the passage in the southeast corner of the bath. A water tank, also covered with a pointed barrel vault, sits just to the north of the toilet. On the eastern exterior of this section is a small window opening to the toilet and, at a lower level to the north of the façade, an inscription. This was evidently a vertical ornamental slab placed in a fountain and seen by looking at the spout hole in its center. Bearing the names of A Alā ad-Dīn Kayqubād ibn Kaykhusraw and Tuğrul, the inscription probably belongs to the old almshouse.
