London's outdoor saunas are the cheap, community end of the city's scene. They sit in yards, car parks and park corners, and most run a wood fire.
The plunge is nearly always on site, usually a stock tank rather than open water. Sessions are booked by the slot rather than dropped into.
In London, 18 of the curated saunas fit this cut. See the full London guide for every venue, or keep scrolling for just the outdoor saunas.
