You can cold plunge at gyms, spas, recovery centers, country clubs, and an increasing number of wellness-focused businesses, or you can set one up at home for anywhere from a few hundred dollars (DIY) to $15,000 (premium tub). The right choice depends on how often you plan to plunge, your budget, and how much you care about controlling the experience.
Commercial Facilities With Cold Plunges
The easiest way to try cold plunging without any upfront investment is to find a business that already has one. The types of facilities offering cold plunge access have expanded well beyond traditional spas. You’ll now find dedicated tubs at fitness centers, boutique wellness studios, sports recovery centers, golf and country clubs, and even some hotels and resorts. Many of these use commercial-grade equipment that keeps water consistently cold and filtered, so you show up, plunge, and leave.
Pricing varies widely. Some gyms include cold plunge access in a standard membership. Dedicated recovery studios typically charge per session (often $25 to $50) or sell monthly packages. Day spas and luxury resorts tend to bundle cold plunge into a broader wellness experience at a higher price point. If you’re just exploring whether cold water immersion is for you, a few paid sessions at a local facility is the lowest-risk way to find out.
To find options near you, search for “cold plunge near me,” “cryotherapy studio,” or “recovery center” in your area. Apps like Yelp, Google Maps, and ClassPass often list cold plunge as a searchable amenity.
Setting Up a Cold Plunge at Home
If you want to plunge regularly, a home setup pays for itself quickly compared to per-session fees. Home options fall into three broad categories: purpose-built cold plunge tubs, DIY chest freezer conversions, and simple no-equipment methods.
Purpose-Built Cold Plunge Tubs
Dedicated cold plunge tubs range from about $3,000 to $15,000. What you get at each tier is meaningfully different.
- Entry-level ($3,000 or less): Typically an inflatable tub paired with a portable chiller. These are compact and easy to set up in a garage, on a deck, or in a backyard. They cool the water reliably but usually lack insulation, built-in filtration, or heating capability. If temperatures where you live drop below freezing, a basic chiller that only cools won’t be able to maintain your target water temperature.
- Mid-range (around $5,000): Molded, hard-shell tubs with better insulation, integrated filtration, and sanitation systems. These hold up to weather, are easier to keep clean (especially if multiple people use them), and generally include features like built-in seating, nonslip flooring, and LED lighting. The jump from inflatable to molded is noticeable in daily comfort and long-term durability.
- Premium ($9,000 to $15,000): Full acrylic construction, dual-temperature systems that both cool and heat water, and powerful chillers that maintain consistent temps year-round. Some high-end models offer a temperature range from 40°F all the way up to 104°F, letting you alternate between cold plunges and hot soaks in one unit. At the top of the range, dual-temp systems handle both therapies in a single tub.
DIY Chest Freezer Conversion
The most popular budget option is converting a chest freezer into a cold plunge. A new or used chest freezer large enough to sit in costs $150 to $400, and conversion kits run a few hundred dollars more. A proper kit includes a waterproof liner (look for spa-grade material), a filtration system with a water pump and skimmer, a wifi-controlled thermostat with a temperature probe, and a safety kill switch that cuts power when the lid is open. Ozone generators are commonly included for water sanitation.
The total cost for a functional DIY plunge typically lands between $500 and $1,200, making it the most affordable option with reliable temperature control. The tradeoffs are real, though: chest freezers aren’t designed for water, so waterproofing the interior properly matters. You’ll also need a GFCI outlet (the type with a built-in circuit breaker, standard in bathrooms and garages) for electrical safety, and the setup requires more hands-on maintenance than a purpose-built tub.
No-Equipment Options
The simplest approach requires nothing more than a standard bathtub and bags of ice. Fill the tub with cold tap water, add ice until you reach your target temperature, and get in. This works fine for occasional use but becomes expensive and inconvenient if you’re plunging multiple times a week. A 10-pound bag of ice costs $2 to $4, and you may need several bags per session depending on your tap water temperature and tub size.
Natural bodies of water are another free option. Lakes, rivers, and ocean water can provide cold enough temperatures for much of the year in cooler climates. The obvious downsides are weather dependence, lack of temperature control, and safety considerations around currents, depth, and water quality. If you go this route, never plunge alone in open water.
Temperature and Duration That Matter
Cold plunging means submerging your body up to your neck in water below 59°F (15°C), though water as warm as 68°F can still trigger beneficial adaptive responses. Most commercial tubs and home setups are kept between 39°F and 55°F. Colder isn’t necessarily better, especially when you’re starting out. Beginning at the warmer end of the range and gradually lowering the temperature over weeks lets your body adapt without overwhelming your system.
For measurable metabolic benefits, researcher Susanna Soeberg’s protocol suggests a total of about 11 minutes per week, spread across two to four sessions. That means individual sessions of roughly 2 to 5 minutes each. You don’t need to push for long, grueling immersions. Consistency across the week matters more than any single session’s duration.
Keeping the Water Clean
If you’re using a home cold plunge more than once or twice, water sanitation becomes a practical concern. You have three main approaches: chemical treatment, ozone, or frequent water changes.
Chlorine and bromine work but can irritate skin with regular exposure, which has pushed many cold plunge users toward ozone generators. Ozone is a strong disinfectant that breaks down into plain oxygen, leaving no chemical residue in the water. Cold water actually helps here: ozone stays stable longer in cold temperatures than in warm ones, making it particularly well-suited for cold plunge applications. Systems that monitor oxidation-reduction potential (a measure of how sanitized the water is) can confirm when levels are in the safe range.
UV sanitation systems are another chemical-free option, often used alongside ozone or minimal chlorine. Purpose-built tubs in the mid-range and above typically come with integrated filtration and sanitation. DIY setups require you to add these components separately. Without any sanitation system, you should drain and refill the water after every few uses.
Safety Considerations
The biggest acute risk of cold water immersion is the cold shock response that happens in the first 30 to 60 seconds. Your breathing rate spikes, your heart rate jumps, and blood pressure rises sharply. For healthy people, this passes quickly and is part of the adaptive benefit. But this same response can trigger dangerous heart rhythm disturbances, even in otherwise healthy individuals. Research published in the International Journal of Circumpolar Health found that the conflict between competing nervous system signals during cold immersion may be a major contributor to cardiac events.
People with cardiovascular disease, uncontrolled high blood pressure, Raynaud’s disease, sickle cell disease, or diabetes should talk to a doctor before trying cold plunging. Hypothermia is the other significant risk, particularly in very cold water or with extended exposure. Start with short sessions, keep a timer visible, and get out if you feel confused, excessively drowsy, or notice uncontrollable shivering that suddenly stops (a sign your body is losing the ability to warm itself).
Wherever you plunge, having another person nearby or at least aware of what you’re doing adds a meaningful layer of safety, especially during your first few sessions when you don’t yet know how your body responds.
