Boulder gyms with a cold plunge (2026).
Very few Boulder gyms have a cold plunge — most cold plunges live in standalone recovery studios that have no gym. Among gyms, ONE Boulder Fitness (downtown, 1800 Broadway) is the clearest option that includes a cold plunge plus a sauna and steam room with a $90/mo membership. A downtown CrossFit box and a national big-box club also have plunges; most traditional gyms don’t.

If recovery is why you’re searching, read this.
Recovery studios do recovery beautifully — but you still need a gym. Big-box clubs have the amenities at a premium price and a mall-scale room. A CrossFit box is a class-based model that isn’t for everyone. ONE Boulder Fitness is the downtown middle path: a full, non-intimidating gym where the cold plunge, sauna and steam room are included, not an add-on.
