Outdoor saunas change the shape of the ritual. Walking between a wood-fired cabin and open water — in whatever weather the day decided on — is part of the session rather than a disruption, and it's usually where the best heat in the atlas lives. Expect barrel, tent, and field setups run by small independent operators.
In London, 6 of the curated saunas fit this cut. See the full London guide for every venue, or keep scrolling for just the outdoor saunas.
