A two person IR sauna gives you all of the heating power of a larger sauna, and it costs less to heat since it is a smaller space. You will enjoy the 140 degree Fahrenheit warmth of an IR sauna with heating bills that are less than what they would be if you got a larger unit. Since two person IR saunas are smaller in space, you may also be able to use a high-quality ceramic heater to heat the unit. This can also help you save money over a higher priced carbon heater.
Two person IR saunas are also an option for people with small spaces. It is fairly easy to add one of these to a bathroom or a basement since their footprint is compact. They maximize the space though, and you and your partner will not feel enclosed in a two person unit. They are a great choice for in-home use.
