Quick Answer
A cold plunge pool is a larger, full-body immersion format with a built-in chiller and filtration: bigger than a barrel and built to live in your space permanently. For most home buyers the Nordic Wave Viking XL (~$8,990, 160 gallons) and The Plunge (~$8,490) are the dedicated pool-format picks; the Polar Dive PRO (~$1,049 with its Pro chiller) and a DIY stock-tank build are the budget routes into the same body position.

A cold plunge pool is the format people picture when they imagine a serious home setup: a deep, chilled, filtered tub you can actually sit down in and submerge to the shoulders, ready whenever you are, with no ice to haul. It sits a clear step above a barrel or a plastic recovery tub, and well below the cost and commitment of digging an inground pool.
This guide is for buyers deciding whether the pool format is right for their space and budget, and which unit to choose if it is. We've researched the live specs and current pricing for every unit in this guide (from $1,049 chiller-and-tub combos to $9,990 premium builds) and pulled out what actually matters when you commit a corner of your home to one.

What Counts as a "Cold Plunge Pool": and What Doesn't
The phrase gets used loosely, so it's worth drawing the line before you spend anything. Three different products all get called "plunge pools," and they're priced an order of magnitude apart.
Freestanding cold plunge pools. These are self-contained units holding roughly 80–160 gallons, with a built-in chiller and filtration. You fill them with a hose, plug them into a wall outlet, and the water stays cold and clean for weeks. This is what most people who search "cold plunge pool for home" actually want, and it's what this guide focuses on. Expect $3,000–$10,000 for a quality unit, or under $1,000 if you assemble a budget chiller-and-tub combo yourself.
Constructed inground or above-ground plunge pools. A true plunge pool is a small, deep swimming pool: a building project with excavation, plumbing, and a dedicated chiller or heat pump. Industry cost guides put these at $15,000–$70,000+ installed, with capacities of 1,000–4,000 gallons. Beautiful, permanent, and a completely different decision from buying a recovery tub. If that's your project, you're hiring a pool contractor, not reading a product guide.
Barrels and recovery tubs. The Ice Barrel and similar verticals give you full immersion in the cold, but you sit upright in a narrow column and, on the cheaper ones, cool the water with ice. They're the gateway format: lower cost, no electrical commitment, smaller footprint.
The rest of this guide treats the freestanding format as the core "pool," because that's the realistic home upgrade. We include one barrel and one DIY route so you can see where the value lines are drawn.
The Pool Picks
Nordic Wave Viking XL: Best Pool-Format Overall
~$8,990 · 160 gallons · cools to 35°F · fits users over 7 feet
The Viking XL is the closest thing to a real plunge pool you can buy as a freestanding unit. At 160 gallons it's the largest tub here, with dual interior steps and enough room to actually extend your legs rather than fold into a barrel. The vertical design is the clever part: it delivers pool-depth immersion while keeping a much smaller floor footprint than a horizontal tub of the same volume, which matters a lot if it's going in a garage corner or a bathroom.
The built-in chiller holds 35°F, the coldest minimum in this group, and Nordic Wave pairs it with app control and a five-year tub warranty (one year on the chiller). Owner reports point to the insulation and fitted lid as the reason running costs stay reasonable for a tub this size: a 160-gallon pool would be punishing to run if it weren't holding temperature well between sessions.
Best for: Buyers who want genuine pool-depth immersion without an inground build, and have the floor space and budget for a premium unit.
The Plunge: Best Premium Build Quality
~$8,490 · ~105 gallons · cools to 37°F · 2-stage filtration
The Plunge is the unit most often used as the benchmark for the category, and the build quality is why. The acrylic-and-fiberglass construction and the 2-stage filtration (ozone plus a 20-micron filter) are what you're paying for. It cools to 37°F, shipping with Plunge's Pro Chiller Gen 2 as standard, and its ozone and 20-micron filter are what keep the water clear between sessions.
It's not the coldest or the largest unit here (the Viking XL goes lower), but for buyers who prioritize a unit that will still be running reliably in five years, The Plunge has the track record. Plan for a standard outlet, a fill source, and a drain nearby.
Best for: Buyers who weight long-term durability and water quality over headline temperature or size.
Plunge All-In: Best Integrated Cabinet
~$9,990 · ~105 gallons · cools to 37°F
The All-In is the top of the Plunge lineup, and what you are buying is the packaging rather than the cold. It holds 37°F, but so does the Original now that the Pro Chiller Gen 2 comes with it, so the temperature advantage the All-In used to have is gone. You get the same build quality and filtration approach, with the chiller and tub designed as a single integrated system instead of two boxes joined by hoses.
At $9,990 against the Original's $8,490, the roughly $1,500 difference does not buy colder water or faster cooling: Plunge publishes 10–12°F an hour for the All-In and 12.5°F for the Pro Chiller that comes with the Original. If the two boxes and the hoses don't bother you, the money is better spent elsewhere.
Best for: Buyers who want a premium plunge as a single integrated cabinet and will pay for it, rather than buyers chasing a lower temperature.
Inergize Cold Plunge Tub: Best Hot + Cold Value
~$2,990 · inflatable tub, 45" × 21.5" interior · 37°F cold, up to 104°F hot · 0.8 HP chiller
The Inergize is the value inflection point, with one thing to know before you picture it in the room: the vessel is an inflatable tub you fill with a hand pump, not a rigid shell. For roughly a third of the price of the premium units, you get a chiller that holds 37°F on the cold side and doubles as a heater up to 104°F, so the same tub gives you contrast therapy without a second purchase. Inergize publishes the chiller as 0.8 HP drawing 890W while it cools or heats, moving 348 gallons an hour through four-way filtration: a strainer, a 20-micron filter, ozone and an air filter.
Inergize gives it a 45" × 21.5" interior with 30" of depth, rated to 6'5" and 300 lbs, which is a single-user tub rather than legroom to spare. The $2,990 is shown against a higher struck-through figure, so treat it as the everyday price rather than a deadline. But as a way into set-and-forget cold without five figures, it's the unit that makes the most sense for most buyers.
Best for: Buyers who want a real chiller-equipped tub and value hot/cold contrast in one unit.
HomePlunge Bella: Turn Your Bathtub Into a Plunge Pool
~$1,999 · 1/2 HP chiller · cools to 41°F · works with 30–90 gallon tubs
The Bella takes a different route to the pool format: instead of buying a tub, you use the bathtub you already own. It's a compact 1/2 HP chiller (about 14.5" × 16" × 17") that drops a standard bathtub from warm to around 41°F in roughly 3.5 hours. That 41°F is also its floor, set in 1°F steps on the touchscreen, and the Bella only cools: there is no heat mode. For anyone with a deep soaking tub and no room for a second vessel, it's the lowest-friction way to get chilled, filtered, full-length immersion.
The trade-offs are honest ones: it's matched to tubs in the 30–90 gallon range, so an extra-deep soaking tub may want a 1 HP unit instead, and you're sharing the chiller with your bathing schedule. But the body position, lying full-length in a bathtub, is arguably more comfortable than sitting upright in a barrel, and you skip the footprint problem entirely.
Best for: Apartment and small-home buyers with an existing bathtub and no space for a dedicated unit.
Polar Dive PRO: Best Budget Pool Format
~$1,049 with the Pro chiller · 106 gallons · 1/3 HP V5 chiller · 39°F Pro / 41°F Standard · fits up to 6'9"
If you want a tub that stays cold and filtered without hauling ice, the Polar Dive PRO is the budget answer. At about $1,049 it pairs a 106-gallon tub with the Pro chiller, which holds 39°F. The Standard chiller holds 41°F instead. That chiller is a 1/3 HP V5 unit running 20-micron filtration 24/7. The chiller is tiny (about 12" × 12" × 13") and light at 40 lbs, so the whole setup stays portable.
What you give up against the premium tier is insulation quality, warranty length, and the lowest temperatures: 39°F is the floor, not 35°F. In a hot garage the 1/3 HP chiller will also work harder to hold temperature. But for the price, it's the most accessible way into genuine pool-format immersion, and it fits users up to 6'9".
Best for: First-time buyers who want chilled, filtered immersion in a real tub at the low end of four figures.
Ice Barrel 500: Best No-Electricity Option
$1,749.99 · 94 gallons · ice-cooled, chiller-ready · fits up to 6'9"
Not every "pool" needs a chiller. The Ice Barrel 500 holds 356 litres (94 gallons), fits users up to 6'9", and has built-in steps and a textured interior seat. It carries an R16 polyurethane foam rating and 3/4" NPT chiller ports, so it runs on ice out of the box and can take a chiller later. No electricity and no plumbing needed to start, but ongoing ice cost in warmer months, and a vertical, upright body position. (Ice Barrel discontinued the older 400 that used to hold this slot; the range is now the 500 and the smaller 300 at $1,149.99.)
It's included here as the deliberate alternative to the pool format: if you don't want a permanent electrical fixture, or you're still testing whether you'll sustain the habit, a barrel is the rational starting point. Many buyers run one for a season before deciding whether to commit to a chiller-equipped pool.
Best for: Buyers who want full cold immersion with zero electrical or plumbing commitment.
DIY Stock-Tank Pool: Lowest Cost Full Build
~$900–$3,500 all in · 100–160 gallons · add your own chiller
The budget pool that recovery forums keep coming back to is a galvanized or poly stock tank fitted with a chiller. A 100-gallon Rubbermaid tank runs around $300 and a 150-gallon around $600; add a 1/3–1/2 HP chiller, an inline filter, and an insulated surround and a complete build lands roughly between $900 and $3,500 depending on how far you take it. The 150-gallon Rubbermaid in particular has become the default DIY plunge vessel.
The appeal is obvious: pool-size volume and a real chiller for the price of a mid-range unit, with full control over the components. The cost is your time, a bit of plumbing competence, and a finish that looks like a project rather than a product. If you enjoy the build and want to choose your own cold plunge chiller, it's the best value here.
Best for: Hands-on buyers who want pool volume and chiller control at the lowest possible cost.
How to Choose a Cold Plunge Pool
Size it to your body first, then your space
The gallon figure tells you how hard the chiller has to work; the interior dimensions tell you whether you'll actually be comfortable. Check the stated max user height before anything else: a tub that fits you to the shoulders seated is the whole point of the pool format over a barrel. Then measure your space, remembering you need clearance to get in and out and access to the chiller for maintenance. Vertical designs like the Viking trade a larger footprint for height; horizontal tubs let you lie back but eat floor.
Match the chiller to your climate
Chiller power is rated for a given volume at a comfortable ambient temperature. In a hot garage or a warm climate, a 1/3 HP chiller on a 106-gallon tub will run more or less constantly to hold temperature, driving up both your electricity bill and wear. If you're in a hot region or sizing a larger tub, step up to a 1/2 or 1 HP unit. This is the single most common mismatch we see in owner complaints.
Budget for running cost, not just purchase
A cold plunge pool is a small appliance that runs continuously. Most single-user units add $15–$50 a month in electricity, and the biggest lever on that number is insulation plus a fitted lid. A well-insulated, lidded tub costs a fraction to run of an uninsulated one at the same temperature, because the chiller only fights slow heat creep instead of re-cooling from scratch. Factor the lid and insulation quality into the purchase decision, not just the sticker price.
Plan your drainage before delivery
None of these units need permanent plumbing, but all of them need to drain somewhere every few weeks. A floor drain, a downhill garden, or a submersible utility pump all work, but decide which before the tub arrives, not while you're standing over 150 gallons of cold water. Showering before each session and keeping the lid on dramatically extends how long the water stays clean between drains.
Frequently Asked Questions
What is a cold plunge pool?
A cold plunge pool is a purpose-built immersion vessel large enough to submerge most of your body, with a built-in chiller that holds a set temperature and filtration that keeps the water clean between sessions. It sits between a portable barrel and a constructed inground pool. Most home units hold 80–160 gallons and run their own refrigeration off a standard outlet.
How much does a cold plunge pool cost?
Freestanding units in this guide include the Polar Dive PRO at ~$1,049 with its Pro chiller, the Inergize at ~$2,990, and the Plunge All-In at ~$9,990. A constructed inground plunge pool is a separate category at $15,000–$70,000+ installed.
What size cold plunge pool do I need?
Match interior length and depth to your body, not just the gallon number. Look for a stated max user height that clears yours, and remember capacity drives chiller workload: 80–110 gallons is the efficient single-user range, while 150–160 gallons gives more room but needs a stronger chiller and costs more to run.
Does a cold plunge pool need plumbing?
Most freestanding units don't. You fill from a hose and the chiller recirculates and filters the same water for weeks. What they need is a 110–120V outlet and somewhere to drain. Only constructed inground pools require true plumbing and dedicated circuits.
Is a cold plunge pool better than a tub or barrel?
It depends on space and budget. A barrel is cheaper and needs no electricity but cools with ice and seats you upright. A pool gives you a built-in chiller, set temperature, filtration, and more room, at higher cost and a permanent footprint. Plunge several times a week with space to spare, and the pool pays back in convenience; still testing the habit, and a barrel or budget chiller-and-tub combo is the smarter start.
How much electricity does a cold plunge pool use?
Most single-user units add roughly $15–$50 a month at average US rates, depending on target temperature, chiller size, and climate. A fitted lid and good insulation are the biggest levers: keep the lid on between sessions and the chiller barely works.
Can you put a cold plunge pool indoors?
Yes. Most units are rated for indoor or outdoor use on a standard outlet. Indoors, plan for condensation, confirm the floor can take the filled weight (a 160-gallon pool is over 1,300 lbs filled), and position near a drain. Outdoors, choose a UV-rated cover and check the chiller's ambient temperature rating.
Our Verdict
If you want a true cold plunge pool (depth, legroom, a built-in chiller, and filtration) and the budget reaches it, the Nordic Wave Viking XL is the unit we'd buy. The 160-gallon vertical design gives you pool-depth immersion in a footprint a horizontal tub of that size couldn't match, it holds the coldest minimum here at 35°F, and the insulation keeps a tub this large from being painful to run. The Plunge is the call if long-term build quality and water cleanliness outweigh size and temperature for you.
For most people, though, the honest answer is to start lower. The Polar Dive PRO at about $1,049 gets you a 106-gallon tub with a chiller on it for a little over a thousand dollars. Prove the habit there first; the five-figure pool will still be waiting if you earn your way to it.
