A sauna and cold plunge setup brings heat and cold water into the same home routine. Start by understanding the precautions, then choose equipment around your space, your preferred sauna style and how you want to cool the water.
The short answer
A sauna and cold plunge combo pairs a heated cabin with a cold-water tub. Plan it around whether cold water suits you, a gradual start and an easy route between the two. Choose equipment by location, power and water care. A chiller's lowest setting is what it can do, not a beginner target.
What does sauna and cold plunge mean?
In this guide, contrast therapy means a planned sequence of sauna heat and cold-water immersion. Owning both pieces gives you access to both experiences, but not every session needs to include both.
Make two decisions separately: whether cold immersion is right for you, and which home setup fits. A bundle simplifies the purchase. It does not prescribe temperatures, times or a treatment plan.
The American Heart Association explains that sudden immersion in cold water triggers a rapid rise in breathing, heart rate and blood pressure, known as the cold shock response. That is why the cold stage deserves its own planning, even if you already enjoy sauna sessions. American Heart Association.
Who should talk to a doctor first?
Cleveland Clinic advises talking to your healthcare provider before cold plunging, especially if you have heart disease, high blood pressure, diabetes, peripheral neuropathy, poor circulation, venous stasis or cold agglutinin disease, or if you are pregnant. Cleveland Clinic.
Explain that your plan includes both sauna heat and cold water. Approval for one does not automatically cover the other.
Good to know. Talk to your doctor before you start if you are pregnant or have a heart condition.
What can a simple routine look like?
For an adult who has confirmed that both activities are right for them, here is one way to organize a session. It is a general planning example, not medical advice.
| Stage | What to do | Planning point |
|---|---|---|
| Sauna | Use the heat and session length that suit you | Keep the door and the way out clear |
| Cold water | Pause, then step in slowly only if you feel well | Follow the temperature guidance below; keep your head above water |
| Warm up | Dry off and put on warm, dry clothes | Keep the towel and clothes within reach |
| Rest | Sit down in a dry spot | End the session rather than repeating out of habit |
Safety points: American Heart Association and Cleveland Clinic.
The American Heart Association warns that an involuntary gasp with your head under water can be deadly, and the cold-water coach it quotes is clear: never do it alone. Have another adult nearby who can help.
For the sauna part, Cleveland Clinic stresses drinking water and not using a sauna after alcohol. Those basics still apply when the sauna is one part of a longer routine. Cleveland Clinic.
Make it easy to skip a stage. Keep the resting spot reachable straight from both the sauna and the tub, so stopping always feels like an option.
How cold should the water be?
Cleveland Clinic suggests 50–59°F for beginners and advises against going below 40°F, checking the water with a thermometer. It recommends one or two minutes for beginners, five minutes at most, and starting once or twice a week. Cleveland Clinic.
Why 37°F is not a starting target
Our chiller ice baths can be set anywhere from 37°F to 108°F. The low end describes what the equipment can reach. It is below Cleveland Clinic's 40°F limit, so it is not the setting a beginner needs.
Pick a setting based on that guidance, then check the actual water temperature before you get in. Treat time limits as a ceiling, not a goal to push through. Cleveland Clinic advises getting out if you feel lightheaded or uncomfortable beyond the feeling of cold, then drying off and warming up.
Do you need a cold plunge with a chiller?
The main equipment choice is how you cool the water. A classic tub uses cold water and ice. A chiller model adds powered temperature control and water care. See all of them on our ice baths page.
| Model | Price | Cooling and power |
|---|---|---|
| 1-Person Cedar Ice Bath, Classic Tub | $3,499 | Cold water and ice; no chiller, no power needed |
| 1-Person Cedar Ice Bath with Chiller | $6,499 | 1HP chiller with built-in ice generator; 110V · 1,160W |
| 2-Person Cedar Ice Bath with Chiller | $10,999 | Built-in chiller with ice generation; 110V · 1,160W |
All three have a red cedar exterior, a stainless steel interior and an insulated cover, and all can stand indoors or outdoors. All are No Electrician Required; the chiller models use a standard plug.
Choose the Classic Tub for a simpler setup
The 1-Person Cedar Ice Bath costs $3,499 and has no chiller: you add cold water and ice. Built-in 1/2″ quick-connect fittings let you add a compatible chiller later. It makes sense if you are happy to prepare the water yourself; see our ice baths without a chiller.
Choose a chiller for temperature control
The 1-Person Cedar Ice Bath with Chiller adds a 1HP chiller, a built-in ice generator, three-stage filtration, ozone and a Wi-Fi app. It costs $3,000 more than the Classic Tub.
The 2-Person Cedar Ice Bath with Chiller costs $10,999 and also includes filtration, ozone and a Wi-Fi app. Its longer tub takes more space, so compare dimensions as well as capacity. Both are on our cold plunge with chiller page.
A chiller is a convenience decision as much as a price one: decide whether preparing ice and water suits your routine, or whether you would rather the tub keep its own temperature.
How much space should you allow?
Measure the whole arrangement, including the route between the sauna, the tub and the resting spot. Start with these sizes:
| Equipment | Dimensions | Planning detail |
|---|---|---|
| Classic Tub | 51.2″ L × 35.4″ W × 27.6″ H | Empty weight: 123.5 lb |
| 1-Person bath with chiller | Tub: 39.4″ diameter × 35″ high | Separate step unit: 39.1″ × 22.4″ × 52″ |
| 2-Person bath with chiller | 78.7″ L × 33.2″ W × 29.7″ H | Leave room to get in and out |
| Bundle's outdoor sauna | 70.9″ × 70.9″ × 70.9″ | Sauna weight: 1,102 lb |
For the 1-person chiller model, draw both the tub and the step unit; the tub diameter alone is not the whole setup. Add the clearances in the manuals, plus room to take off the cover and get in and out.
Plan the walking route first
Canada's National Collaborating Centre for Environmental Health lists slips and falls around cold plunges as a real hazard, including ice on outdoor decks, walkways and steps. Plan a clear route with good grip and drainage, and keep hoses, cords and loose items out of the way. NCCEH.
Count the filled tub and the people using it when you check floor or deck support; the Classic Tub's empty weight is not the working load.
For an indoor setup, pair the bath with one of our indoor saunas; our basement sauna guide covers height, access and room preparation. The bundle's sauna is an outdoor model.
What power does the setup need?
The bundle combines two different electrical needs:
| Component | Power | Electrician |
|---|---|---|
| 4-Person Outdoor Traditional Cedar Sauna | 240V · 6,000W | Electrician Required |
| 1-Person Cedar Ice Bath with Chiller | 110V · 1,160W, standard plug | No Electrician Required |
A standard plug still needs a suitable grounded outlet and the protection the equipment instructions call for. Keep cords and outlets well away from the water.
When you order the sauna, you can add Professional Assembly ($999) on its product page; it puts the cabin together. Electrical work is separate; your electrician installs the circuit.
Is the bundle better than buying separately?
The Outdoor Contrast Therapy Bundle pairs the 4-Person Outdoor Traditional Cedar Sauna with the 1-Person Cedar Ice Bath with Chiller.
| Purchase | What you get | Price |
|---|---|---|
| Separately | The same sauna and chiller bath | $6,999 + $6,499 = $13,498 |
| Outdoor bundle | The same two products together | $11,999 |
| You save | On the listed prices | $1,499 |
Choose the bundle if those are the two pieces you would pick anyway. The sauna has a 6kW Harvia stone heater with steam, reaches up to 194°F and warms up in about 45 minutes.
Buy separately if you prefer an infrared sauna, need an indoor cabin, want the Classic Tub or a 2-person bath. Start with the location and heating style, then compare. The saving helps only when the equipment fits your plan.
Warranties differ by piece: our saunas carry 10 years; our ice baths carry 10 years on the tub and structure and 1 year on the chiller.
What care does the water need?
Filtration and ozone help, but they are not a reason to skip water care. NCCEH explains that ozone leaves no lasting disinfectant in the water, and that cold water also slows how well disinfectants work. Follow your model's cleaning, water treatment, filter and water-change instructions instead of judging the water by how clear it looks. NCCEH.
A quick rinse before you get in keeps sweat and oils out of the tub; NCCEH recommends showering before entering the water. Build that step into the route from sauna to tub.
Keep the insulated cover on between outdoor sessions. A cover is not a child-safety barrier, so plan how you will keep children away from the water when no adult is watching.
Frequently asked questions
Should I start with the sauna or the cold plunge?
This guide uses a sauna-first order, but it is not a rule. Make sure both are right for you, and feel free to stop after either one.
Do I need to use the 37°F setting?
No. That is the chiller's lowest setting, not a recommendation. Cleveland Clinic suggests 50–59°F for beginners and never below 40°F.
Can I do this every day from the start?
Cleveland Clinic suggests beginners cold plunge once or twice a week and add days only as they get used to it.
Can I use a tub without a chiller?
Yes. The Classic Tub uses cold water and ice and needs no power. Choose it if you are happy to prepare the water yourself.
Does ozone make the bath maintenance-free?
No. Keep the cleaning, water treatment and filter steps from your manual. Ozone is one feature of the chiller models, not a replacement for care.
How much does the outdoor bundle save?
$1,499. The sauna and the 1-person chiller bath cost $13,498 separately and $11,999 as a bundle.
