Quite a few Boulder-area gyms have a sauna, but their websites often don’t say what kind it is or whether it costs extra. ONE Boulder Fitness (downtown, 1800 Broadway) has a traditional dry cedar sauna, included with a $90/mo membership, plus a steam room and the Cool Tub in the same suite.

What to ask about any gym’s sauna.
- Is the sauna included in the membership, or is it an add-on or a separate booking?
- Is it a traditional dry sauna, an infrared cabin or a steam room?
- Can you walk in whenever the gym is open, or do you need to reserve a time?
- Can you try it first on a day pass?
Real, dry, traditional heat.
Our sauna is a full cedar, traditional dry sauna, about 180°F+, steps from the gym floor. It’s included with membership, alongside the steam room and the Cool Tub, so you can warm up in the sauna and then cool off in the Cool Tub without leaving the building. You can try it on a free day pass or ask about short-term passes.
