as well as two other more private locker areas with individual doors that can lock these two separate locker rooms. The second type of sauna is the Finnish sauna type one can find in any gym throughout the world or a hotel. It could be in the locker room or mixed (i. e. male and female together). Attitudes towards nudity are very liberal and people are less self-conscious about their nude bodies. The third type of sauna is one that is rented by a group of friends. It is similar to the public banya bath house type, except that it is usually more modern and luxurious, and is often rented by groups of friends by the hour for the use of partying and socialising.

North America and Central America In the United States, the earliest saunas that arrived with the colonists were Swedish bastus in the colony New Sweden around the Delaware River. The Swedish Governor at the time had a bathhouse on Tinicum Island. Today sauna culture enjoys its greatest popularity in the Lake Superior Region, specifically the Upper Peninsula of Michigan, especially the Keweenaw Peninsula, and parts of Minnesota, Wisconsin, and Iowa, which are home to large populations of Swedish and particularly Finnish Americans. Duluth, Minnesota, at its peak, had as many as 14 public saunas.

Elsewhere, sauna facilities are normally provided at health clubs and at hotels, but there is no tradition or ritual to their use. To avoid liability, many saunas operate at only moderate temperatures and do not allow pouring water on the rocks. A wider range of sauna etiquette is usually acceptable in the United States compared to other countries, with the exception that most mixed-sex saunas usually require some clothing such as a bathing suit to be worn.
