Sauna in Idaho Falls
At PLUNJ Idaho Falls, our dry sauna is heated by an electric stove and operates between 175–190°F with approximately 20% humidity. Pour water over the stones to create a burst of steam, settle in, and let the heat do its work. Most guests spend 10–15 minutes in the sauna before transitioning to the cold plunge — a simple, effective rhythm that leaves you feeling better than when you came in. Whether you're an Idaho Falls local or visiting for the first time, our sauna is where recovery and relaxation meet.

Cold Plunge in Idaho Falls
At PLUNJ Idaho Falls, our cold plunge pool is maintained between 45–50°F and spacious enough to accommodate up to four people at a time. After your time in the sauna, stepping into the cold water is where the magic of contrast therapy happens. Most guests spend anywhere from 30 seconds to 5 minutes in the plunge, letting the cold work to reduce inflammation, boost circulation, and elevate mood. It's a challenge worth taking — and one that Idaho Falls locals keep coming back for.
