Sultan Amir Ahmad Bathhouse (Persian: حمام سلطان امیر احمد, romanized: Hammam-e Sultan Amir Ahmad), also known as the Qasemi Bathhouse, is a traditional Iranian public bathhouse (hammam) in Kashan, Iran. It was constructed in the 16th century, during the Safavid era; however, the bathhouse was damaged in 1778 as a result of an earthquake and was renovated during the Qajar era. The bathhouse is named after Imamzadeh Sultan Amir Ahmad, whose mausoleum is nearby.
