Vakil Bathhouse is constructed in Zand Period, in the center of Shiraz to the order of Karim Khan-e Zand. It observes the most advanced architectural principles of its time. For example, entrance of the bathhouse is small that reaches the entrance vestibule located below the ground level, with a gentle slope to prevent cold air entering the bathhouse and warmth escaping it. The locker is a regular octagon with a dome ceiling and eight monolithic pillars in the middle. The hothouse is covered with paving below of which there are narrow corridors where hot air and water steam flew to warm the bathhouse floor sooner. The bathhouse is on the south of the hothouse with two large pots to warm water. On both sides of the hothouse, there are two alcoves. The alcoves, which were for the kings are a very scenic part of Vakil Bathhouse. Elegant lime work patterns can be seen under the dome of this bathhouse. Vakil Bathhouse has been registered as a national monument of Iran.
