Most UK lake saunas are actually on Scottish lochs. Loch Tay, Loch Lomond and the Cairngorm waters carry the bulk of them, generally in open country rather than a town.
The few English entries sit beside reservoirs in Yorkshire and the north east. Most are wood-fired and outdoors, with the water itself serving as the cold side of the cycle.
In the United Kingdom, 13 of the curated saunas fit this cut. See the full the United Kingdom country guide for every venue, or keep scrolling for just the lake saunas.
