The plunge here belongs to a building rather than a yard. These are bathhouses with chilled pools, steam rooms and ice rooms, so the cold is engineered rather than borrowed.
Brooklyn and Manhattan split the bulk of it, and the cut reaches out through Queens to the Jersey suburbs. Many run aufguss on a schedule and serve food, so a session turns into an afternoon.
In the NYC Metro, 18 of the curated saunas fit this cut. See the full the NYC Metro region guide for every venue, or keep scrolling for just the saunas with a cold plunge.
