Located outside the city walls, on the street connecting Sinān Pāšā's mosque with that of Murād Pāšā an-Naqšbandī, this bathhouse belongs to the Mamlūk era. 

The bathhouse was mentioned in the endowment foundation of al-madrasā al-ʾAfridūnīyyā. According to Sauvaire (after al-ʿAlmawī and an-Nuʿaymī), the founder of the madrasa died in 1348; consequently, the bathhouse was constructed in or before that year. Another clue is the marked similarity between the muqarnas of the bathhouse's cupolas and those ornamenting the minaret of Tankiz Mosque, erected in 1317. Briefly, there exists adequate evidence that the building was originally constructed at the beginning of the 14th century, later modifications notwithstanding. 

The bathhouse was functioning in 1943 when its condition was described as fair by Écochard and Le Cœur.  

Fast forward to 2009, when the Danish Institute's study was published. Professor Stefan Weber describes the structure's condition as "good" but gives 1397 as the year of construction. He adds, relying on an inscription, that the bathhouse was modernized in 1872.
