In general, the Sultan Amir Ahmad bath generally includes two small and large baths, which were used by the people of Kashan in the past and on some days of the week. In the following, we will introduce you to the different parts of the bathroom.

Large bathroom : 

1. Entrance : In old bathrooms, you have to go through several spaces to enter the dressing room (the first large space in the bathrooms).
   Jalokhan: an area of the entrance that is located before the entrance and in front of it.
   Entrance gate : The gate is one of the important parts of the architecture of old Iran and characteristic of the building. The head of the Sultan Amir Ahmad bath is decorated with beautiful motifs, among which we can mention the motifs of flowers and pigeons, as well as statues and images of men and women, and images of hunting grounds around the city. Unfortunately, some of these motifs have been severely damaged. The main part is decorated with tiled backs, Yazdi arches and moqrans carved arches, and the stucco above the door and other parts of the main part show a special elegance and beauty to the viewer’s eyes.
   Vestibule and communication corridor : This section is located at the entrance of the building and is located immediately after the entrance and door. The vestibule is a space for communication between outside and inside. This space is connected to the inside of the building using a corridor. A simple and well-proportioned formalization can be seen in the vestibule ceiling of the Sultan Amir Ahmad bath. Formalization is an evolved form of cornering where, using a single mould, arches are placed at intervals of the four main arches, thus turning the square into an octagon. After passing through the vestibule, you will encounter a winding hallway that leads to Serbineh. The reason for the existence of winding corridors between the vestibule and the headroom is that the sudden change in air temperature does not disturb the visitors and convection does not take place between the hot air of the bathroom and the cold air outside.
2. Serbina : Sarbineh or bineh is the first important space of bathrooms. Sarbineh is actually a kind of dressing room and a place to prepare for bathing or leaving the bathroom. This section is located between the entrance to the bathroom and the greenhouse. In the past, the air in Sarbineh was kept semi-warm so that customers would not face hot air all at once; In addition, when leaving the hot house, the cold air will not hit them and there will be no problems for people’s health.
   The most decorated baths are seen in Sarbineh, and Sultan Amir Ahmad bath is no exception. There is precise and regular lighting in Serbineh; An indicator that doubles the effect of existing decorations and creates a stunning atmosphere. Sultan Amir Ahmad’s bathhouse is built in an octagonal shape, and its beautiful stucco and formalized ceiling are among its attractions. The stone shoe racks of this section are also really beautiful next to the columns and walls decorated with mosaic tiles. The floor of Sarbineh and the platforms around it are stone.
   The plinth (a part of the wall of the room or porch that covers from the floor of the niche to the floor) is tiled in the bathhouse of Sultan Amir Ahmad, and in combination with the tiling of the middle dome of this section, it creates a beautiful atmosphere. The tiling of this section is of the bell type, where clay tiles are used; The tiles that have a glass glaze on them and are fired in the oven.
   On the roof of Sarbineh, the phrase “La-e-el-e-Allah” is engraved in the direction of the Qibla, and on the opposite side, the date 1875 shows the restoration of the place after the devastating earthquake of the Zandiyeh period. It is said that this roof was destroyed in this earthquake and at the same time as the house of Borujerdi was built in its vicinity, the construction of brick roof and tiling was done. In the middle of the formalization of the roof and exactly above the pond, there is a large skylight with tile patterns on its edge.
   One of the questions of the visitors about Sultan Amir Ahmad’s bathhouse is why this section is so large. The answer to this question lies in the use of the bathroom in the past. In the old days, the bathroom was not only a place for washing the body, but it was used as a place for gathering friends and solving life issues, spending leisure time, talking, relieving fatigue, and even worshiping; For this reason, the headspace is very large.
3. in between :After passing through Sarbineh, you will face a space called “Miyan Dar” which will take you to the greenhouse with two 90 degree turns. “Miyan door” has a meandering design to prevent the direct exchange of heat and humidity and prevent the air from outside the bathroom from being transferred to the greenhouse and the air from the greenhouse to the greenhouse and vice versa. The entrance to the greenhouse and its exit to the greenhouse are placed opposite each other to maintain the axis of the space. Other service spaces, including washrooms and cleaning spaces, were also located “between the doors”.
4. warm house : The hot room is the second main space of the Sultan Amir Ahmad bath, which was used for washing and purifying the body in the past. The warm atmosphere of the house is simpler than Sarbineh and there are corners for sitting and washing.
   The plinth and the warm wall of the house are decorated up to one meter with mosaic tiles, and from there to the ceiling, there is limestone with Saroj mortar. Saroj is a water-resistant mortar made from lime and ash, clay, etc. Four columns divide the warm space of the house into three middle parts (the road and getting to the treasury) and two smaller parts in the periphery (for sitting and bathing); Sections that each have a pond in the middle.
5. Treasury : Hot water tank, cold water pool and more private spaces for bathing are located next to the hot house. The door of the bathroom safe is installed right in the middle of the opposite side of the entrance.
   The treasury is a small room for washing, which is located on the “Golkhan” and it is half filled with water. In the past, in full baths, there were three vaults, one for hot water, one for cold water, and in the middle of the two, a vault for lukewarm water. At the time, no one was allowed to step in both cold and hot water reservoirs.
   Garam was a private house in two corners of the treasury for nobles and nobles. Instead of a treasury, these spaces had a small basin called a handstand, from which people took water and poured it on themselves. The arches and parts of the greenhouse were decorated with limestone; Decorations that have unfortunately suffered a lot of damage over time. Toize is a plaster part of the building on the ground, on which the arch is mounted, and it is the factor of transferring compressive loads to the side and bottom walls.
6. Tun or Gulkhan : Some of the bathroom spaces were built for support, among which we can mention the spaces for water and heat supply, such as tun and firewood storage. Tun, Gulkhan, Tun or Pathion refers to the set of corridors, chambers and copper dishes that are located on the floor and under the treasury.
   A copper dish in the form of a small pit was placed in the bottom and center of the treasury. Under this container, there is a chamber that leads out of the bathroom through a corridor. At regular intervals, a person named “Toon Tab” lit firewood and other fuel in the ton to keep the water in the tank warm. The smoke from burning firewood in the oven did not go directly to the chimney; Rather, he first passed through the cat faces on the bathroom floor.
   Catholes are ventilation holes under the floor of the hot house, which have different corridors and smoke and fire exited the bathroom through them and then through the chimney. The chimneys actually played the role of modern radiators in the bathroom, and passing the smoke through the chimneys warmed the bathroom floor. In Sarbineh, there are fewer of these cats so that the air is semi-warm.
7. Small bathroom : A small bathroom is a bathroom with a simple entrance that leads to the bathroom after passing through its corridor. The head space of the small bathroom has a base of eight and a half eight and platforms can be seen around it. The formal arch above the headboard and the ceiling and plinth decorations of this space are similar to the headboard of the large bathroom.
8. bathroom roof : The roof of the Sultan Amir Ahmad bathhouse is the masterpiece of this building and one of the most beautiful dome-shaped roofs in Iran. So, when visiting this building, don’t forget to go to its roof and take souvenir photos. There are a number of domes on the roof of this bathroom, each of which has convex lens glasses. The reason for installing these lenses is to provide enough light to different parts of the bathroom and prevent the view inside. It is interesting to know that the ancients believed that the devil’s eye looks into the bathroom.The interior light of the bathroom spaces was provided by Jamkhaneh or Goljam and directly from the ceiling of the bathroom, and nowadays artificial lights also help to illuminate the space. These glass elements can be seen throughout the roof space and provide the bathroom with light all year round.
   The number of glasses in the cups is based on the area of Sultan Amir Ahmed’s bath; In addition, the diameter of the cups and their number are determined depending on the heat and cold of the space below them. In some seasons of the year, the temperature and humidity of the air in Sarbineh was adjusted by removing the glajams of this skylight. In the past, the roof of the bathrooms was also a place to dry people’s clothes, lang and velor (a large towel for drying the upper half of the body); For this purpose, there was a staircase to access the roof.
