This structure is located 21 kilometers north of Mahabad, within the village of Laj. Considering the region's history, similar buildings, and the materials used in its construction, its age dates back to the years 1050 to 1100 AH (i.e., the Safavid era). The foundations and substructure of the bathhouse are made from locally available stones, while the rest of the building is constructed from red square bricks. The area under the entrance dome is designed as a four-arched space, with the distance between the two arched bases being fourmeters. The bases are square, each side measuring 1.5 meters. The main bathhouse area has an internal circumference of 35 meters, built in three continuous sections with eight arches, and its current height from the ground to the brick section is 1.75 meters. The building has two large brick domes and six smaller brick domes of various sizes. Like other old bathhouses, it includes entrance spaces, a dressing room, a hot room, and a reservoir, but it is no longer used as a bathhouse. This structure was registered as a national heritage site under number 4848 in 2001.
