Plunj Idaho Falls

Plunj Idaho Falls on S 25th E has a dry electric sauna and a cold plunge pool for up to four, in one-hour sessions open seven days a week.

Plunj Idaho Falls keeps it simple: one dry sauna, one cold plunge, and an hour to move between them. The sauna runs on an electric stove at 175 to 190°F with about 20% humidity, and water poured on the stones sends up a burst of steam. The plunge is kept between 45 and 50°F and has room for four. How a session goes A session is 60 minutes with full access to both rooms. The studio recommends 10 to 15 minutes in the sauna, 30 seconds to five minutes in the plunge, and a couple of minutes of rest before repeating the round up to three times. Towels are provided; bring swimwear, a water bottle and sandals or flip flops.
