The public bath was constructed below ground level to save energy and tap into groundwater sources.
Navab Bath, which dates back to the Qajar era, is in the vicinity of Tehran’s Grand Bazaar.
To save energy and tap into groundwater sources such as qanats and springs, the structure was built below ground level.
Originally, bricks, lime, stones and tiles were used in the construction of the public bath, during its renovation, however, cement was added to the building to strengthen its structure.
