How to Plan a Contrast Therapy Event (Sauna + Cold Plunge)

If you've never done contrast therapy — alternating between a hot sauna and a cold plunge — you're in for a treat. It's the single most requested service type in our directory, and for good reason: the endorphin rush is real, the bonding experience is incredible, and your guests will talk about it for months.

Here's how to plan one that goes smoothly.

Step 1: Pick Your Setup

You need two things: a mobile sauna and a cold plunge tub. Most vendors offer both as a package. If your vendor only does saunas, you can book the cold plunge separately — but bundling is easier and usually cheaper.

You'll need a flat outdoor space that can fit both. A backyard, driveway, or event venue with some open space works. The sauna and plunge should be close together — ideally 10-20 feet apart so people can transition quickly.

Step 2: Plan the Flow

The classic contrast therapy cycle is: 15-20 minutes in the sauna, 1-3 minutes in the cold plunge, then 5-10 minutes resting. Repeat 2-3 times.

For an event, you don't need to be rigid about it. People will naturally find their rhythm. Some will do one round and be done. Others will go four rounds. Let it be self-directed — the only rule is no phones in the sauna (they'll overheat).

Step 3: Set the Scene

The contrast therapy itself is the main attraction, but a few extras make the experience feel premium. Have a rest area with chairs or blankets between sessions, a cooler with cold water and electrolytes close by, towels (lots of them), and some ambient music if you're feeling it.

If it's an evening event, string lights around the area transform the vibe completely.

Step 4: Brief Your Guests

Most people haven't done contrast therapy before. A quick 2-minute explanation at the start goes a long way. Tell them what to wear (swimsuits), what to expect (hot, then cold, then amazing), how long each session is, and that it's totally optional — no pressure.

Step 5: Book Smart

For a group of 10-20 people, a 4-hour rental is ideal. The sauna fits 4-8 people at a time, and the cold plunge is one at a time, so 4 hours gives everyone plenty of rounds.

Pricing for a full contrast therapy setup is typically $500-1,500 depending on your city and vendor. Get quotes from vendors in your area to see what's available.
