Seaside saunas use the sea as the cold plunge. Most of the venues on this cut are wood-fired barrels or small cabins within a few metres of the tideline, and most of their regulars are year-round cold-water swimmers. January sea is a different animal from August sea — check the season, not just the forecast, before committing.
In England, 5 of the curated saunas fit this cut. See the full England region guide for every venue, or keep scrolling for just the seaside saunas.
