Take a bathhouse in my hometown as an example: if the water is free, then only the boiler and room, the decoration cost of the room, and the coal and electricity cost of boiling water will be invested. If the upfront investment is not counted, the daily cost is the cost of fuel and water and electricity for burning the boiler. Rural electricity consumption in 0.5 yuan is about one degree, about 20 degrees, and the total is about 10-20 yuan; The daily cost of coal is about 50- 100 (the fuel in our village bathhouse is almost free, and the waste from the paper mill is used, which saves the cost but causes great pollution). If water costs money, the cost will increase a lot accordingly. The water fee is different in each area, and the number of people taking a bath also determines the water consumption. This fee is not fixed.

If there are not many people, you don't have to keep burning the boiler, and the daily cost is not more than 100 yuan.
