Amsterdam's plunges are mostly outdoor, inexpensive, and heated electrically. The heat is not really the point here: the cold and the repeated cycle are what the session is built around.
Most sit in gardens or on the water rather than inside a spa building. Ice rooms and floating setups both turn up on this cut.
In Amsterdam, 7 of the curated saunas fit this cut. See the full Amsterdam guide for every venue, or keep scrolling for just the saunas with a cold plunge.
