Recent excavations (1994–2009) show that there was a special room below the room of Hammamkhana, where archaeologists found the arrangements for heating water, supplying the hot water as well as cool water to the Hammamkhana through the terracotta pipes which was specially manufactured for such purpose.
Penggalian baru-baru ini (1994-2009) menunjukkan bahwa terdapat ruang khusus di bawah ruangan Hammamkhana, di mana para arkeolog menemukan pengaturan untuk memanaskan air, memasok air panas serta air dingin ke Hammamkhana melalui pipa terakota yang khusus dibuat untuk tujuan tersebut.
