When it comes to the dimensions of a sauna, there is no one-size-fits-all answer. The dimensions of your sauna will depend on the size of the room or area in which you plan to build it. For a standard sized room, the dimensions are typically around 12 feet by 12 feet. However, if you have a larger space available, you may want to consider building a larger sauna to take advantage of the extra space. Keep in mind that the size of your sauna will also affect how many people can comfortably use it at one time. If you plan on having multiple people use your sauna at once, be sure to factor that into your decision when choosing its size.
