It appears that Sinan relied on pre-existing plans for the hamams he built.
However, as he had done in other cases, he applied his favourite theme of the
extended central dome, gathering the main hall and private rooms of the hot room
area under one central dome. For this purpose, he kept the private bath room
walls low, had the central dome supported by a four or eight' based system
consisting of columns and arches and covered the neighbouring areas with vaults
or cupolas. The best examples of this plan are the Suleymaniye Hamam (1557),
the Sokollu (Yesildirek) Hamam at Azapkapi (date unknown), the Valide Sultan
Hamam in the Topkapi Palace (date unknown), which has now lost its original
character and the
Hunkar Hamam (date unknown). The Ayasofya Haseki Hurrem Sultan Hamam (1556)
is one of the well preserved
hamam buildings open to visitors today. Here Sinan has juxtaposed the men's and
the women's sections so as to create an interesting mirrored complex. Ot-her
important examples of Sinan's hamams are the Hayrettin Pasha "(Cinili)
Hamam in Zeyrek (between 1540-46), the Edirnekapi Mihrimah Sultan Hamam (1565?),
the Sokollu Hamam in Edirne (1568), the Sokollu Hamam in Luleburgaz (1570)
and the Payas Sokollu Hamam (1575?) in the province of Antioch.
