In What Order Should You Use the Sauna, Steam Room, Hot tub and Cold Plunge?

By Lauren Stacks|Published on:

Build the heat up, then go cold. For most people the best order is steam room, then dry sauna, then cold plunge, with a few minutes of rest before the next round. The hot tub works best at either end, as a gentle warmup before the steam room or as a slow rewarm after your last cold dip.

There's no single official sequence, and plenty of spas run their circuits differently. What follows is the order we recommend for most healthy adults, along with the times, temperatures and safety rules that make each stage work.

What's the best order for a full spa circuit?

Think of the circuit as a climb to peak heat followed by one sharp drop. Each heat stage gets a little more intense, so your body warms gradually, and the cold plunge lands right after the hottest stage, where the contrast is biggest.

Stage

Typical temperature

Time

Why it sits here

1. Hot tub (optional)

100°F to 104°F water

5 to 10 min

Gentle warmup that loosens you up before the rooms

2. Steam room

110°F to 120°F air, about 100% humidity

10 to 15 min

Lower air temperature makes it the softer of the two heat rooms

3. Dry sauna

150°F to 195°F air, 5% to 30% humidity

10 to 15 min

Peak heat of the circuit, right before the cold

4. Cold plunge

Set to your level, colder as you adapt

1 to 3 min

Biggest contrast lands right after peak heat

5. Rest or rewarm

Room air, or the hot tub

5 to 10 min

Sources: sauna and steam room ranges from Jacuzzi's sauna vs steam room guide; hot tub ceiling from the U.S. Consumer Product Safety Commission. Repeat stages 2 to 5 for two or three rounds.

If your spa only has some of these, drop the missing stage and keep the logic: warmer to hottest, then cold, then rest.

Should you do the steam room or the sauna first?

Steam room first, in most cases. A steam room runs far cooler than a dry sauna, typically 110°F to 120°F against 150°F to 195°F, but the near total humidity makes it feel intense fast. Starting there warms you without the sharp edge of dry heat, and the sauna then takes you to the top of the climb.

That said, some people find wet heat harder to breathe in. If that's you, flip them or skip the steam room. If you're choosing between sauna styles at home, our breakdown of which type of sauna to use covers infrared against traditional.

Can you go from a hot tub straight into a cold plunge?

Yes, for healthy adults. It's one of the simplest contrast pairings there is. Keep the hot tub at or below 104°F, which is the ceiling the U.S. Consumer Product Safety Commission sets for safe soaking, and rinse off before you step into a shared cold plunge so you're not carrying hot tub chemicals and body oils into the cold water.

We cover hot tub timing, rounds and the common mistakes in our guide to alternating a hot tub and cold plunge.

How long should you stay in each one?

Less than you think. The whole point of a circuit is repeated contrast, not endurance in any one room, so short stages done well beat one long sit.

For a sense of weekly volume, a 2021 study in Cell Reports Medicine led by Susanna Søberg found that the regular winter swimmers it followed logged about 57 minutes of sauna heat and 11 minutes of cold water immersion per week. That's what experienced practitioners were doing, not a prescription, but it shows how small the cold dose really is.

Should you end on hot or cold?

It depends on what comes next. Finishing cold leaves you alert and is the better pick for mornings or before work. Finishing warm, with a final soak in the hot tub or a few minutes in the steam room, helps you wind down and suits evenings.

Our step by step sauna and cold plunge routine goes deeper on the ending and on adjusting the routine around training days.

Can you build this circuit at home?

You can get close with two pieces. The Polar Monkeys Contrast Edition has two sides, a vertical barrel and a horizontal tub, each with its own ChillX system and each adjustable from 32°F to 107°F, so one side can run hot while the other runs cold at the same time. Set the hot side at or below 104°F when you're soaking in it, in line with CPSC guidance.

Pair it with a sauna from the Polar Monkeys residential sauna collection, the Baia for indoors or the Mira for outdoors, and you have the heat, the hot soak and the cold in one space. For the bigger picture on pairing the two, see our guide to combining sauna and cold plunge.

Who should skip the circuit or talk to a doctor first?

Stacked heat and cold put real demand on your heart and blood pressure. Check with your doctor first if you have a heart condition, high or low blood pressure, or you're pregnant. The CPSC advises pregnant women to keep hot tub water at 100°F or below and warns that water above 102°F can harm a developing baby in the first trimester.

Skip alcohol before or during the circuit too. The CPSC notes that drinking while soaking can cause drowsiness and raises the risk of drowning. And if you feel dizzy, nauseated or lightheaded at any stage, get out and rest.

Frequently asked questions

Is a steam room or a dry sauna better before a cold plunge?

Both work. A dry sauna runs hotter, typically 150°F to 195°F, so it gives you a sharper contrast going into the cold plunge. A steam room runs 110°F to 120°F at near total humidity, which suits people who find dry heat harsh. If you have both, use the steam room first and the sauna last.

How many rounds of the full circuit should you do?

Two to three rounds is plenty for most regular users. On your first visit, do one round with shorter stages and see how your body responds before adding more.

Can you do steam, sauna and cold plunge every day?

Many healthy adults do, but daily use isn't required to benefit. Polar Monkeys' own routine guide recommends two to four contrast sessions a week for most people. Scale back if you feel run down, and talk to your doctor if you have a heart or blood pressure condition.

Do you need to shower between stages?

Rinse off before getting into a hot tub or a cold plunge, especially a shared one. It keeps sweat, oils and hot tub chemicals out of the water. You don't need a full shower between the steam room and the sauna.

How cold should the cold plunge be after a sauna?

Cold enough that you want to get out, but not so cold you can't control your breathing. New plungers often start in the 50s Fahrenheit and work colder over weeks. A Polar Monkeys residential plunge can go as low as 32°F once you're ready
