What a traditional sauna is
A traditional sauna is a hot wood-lined room heated by a stove, often with rocks you can ladle water onto for a burst of steam (the Finns call it loyly). The air is hot and fairly dry. Public saunas in the US range from wood-fired cabins by a lake to social sauna clubs in a city storefront.

Etiquette
