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, so check the season, not just the forecast, before committing.
In Australia, 10 of the curated saunas fit this cut. See the full Australia country guide for every venue, or keep scrolling for just the seaside saunas.
