If you want a cold plunge with a chiller, finding one takes five minutes, and comparing them takes an afternoon, because every brand lists a different set of numbers in a different place. I opened the maker or retailer page for each tub below and wrote down only what it showed, with the date (2026-10-06) because prices move. Where a page left something out, I say so instead of filling the gap, and that list of gaps is the part I couldn't find cleanly anywhere else.
Best cold plunge with chiller: quick picks
Prices are what each page showed on 2026-10-06 and will change. "Not shown" means I could not find it on the page I opened.
| Tub | Price shown | Water capacity | Chiller / circuit | Temperature | Warranty |
|---|---|---|---|---|---|
| The Plunge | $5,990 (listed down from $6,990) | about 105 gal | 1/2 HP, 120V / 15A GFCI | down to 39°F | 12 months |
| Renu Cold Stoic 2.0 | $9,499 | 95 gal filled | 0.25 HP, 120V / 15A | as low as 39°F | 5-year limited |
| Renu Cold Stoic 3.0 | $11,399 | 95 gal filled | 0.5 HP, 120V / 15A dedicated recommended | 37–104°F | 5-year limited |
| Renu Vero | $7,200 cold only, $7,500 hot + cold | 95 gal filled | 0.8 HP, 120V / 15A dedicated | 37–100°F | 5-year limited |
| Ice Barrel 500 + chiller | $5,749.98 bundle | 94 gal (retailer listing) | Not shown | Not shown | Limited lifetime |
| Dynamic Cold Therapy (Salus listing) | $8,495 | up to 135 gal | 1 HP motor, 0.8 HP compressor, 120V / 15A | 37–85°F | 1-year limited |
| Coldture Classic + Chiller Pro | $3,499 sale, $3,999 regular | 400 L | 120V, 8A, standard 15A outlet | 37–104°F | 1 year tub and chiller |
If I had to pick one for most backyards, it would be the Vero, for reasons I explain in the product sections. If you only care about the lowest cold plunge chiller price in this group, it's the Coldture bundle, with the caveats I list below.
How I picked and what I can't claim
I don't test these tubs. I'm not an engineer, and I haven't touched, filled, plugged in or measured any of them. Everything below is "the maker says" or "the listing shows".
I chose seven tubs that sell a chiller as part of the package (or, for Ice Barrel, as a bundle), that I could open a maker or retailer page for, and that run on a regular 120V outlet. I left out any brand whose page wouldn't load for me, and a couple of well-known names for that reason alone. That isn't a verdict on them.
Things I could not verify, so you know where to push the seller:
- Cooling speed in real conditions. Plunge says its standard chiller gives "4-6 degrees per hour" and the Pro "8-10 degrees per hour". Dynamic Cold Therapy's own pages give 1–3°F per 20 minutes in one place and per 30 minutes in another. Those are claims, and the surrounding air and water volume change the answer.
- The Ice Barrel chiller's horsepower, voltage and amperage. The pages I opened didn't list them.
- Exterior dimensions for The Plunge and the Dynamic tub's full footprint with the chiller placed beside it.
- Noise at your actual install spot. Renu lists 58 decibels at about 3 feet for its tubs; I found no equivalent figure for the others.
- Long-term reliability. I have no failure-rate data and I won't pretend to.
Health note: research on cold water immersion is mixed. Cleveland Clinic describes the evidence for some benefits as preliminary and says to talk to your healthcare provider before plunging, listing heart disease, high blood pressure, diabetes and pregnancy among the conditions where people should avoid it. If any of that applies to you, ask a doctor first.
The Plunge
The Plunge is the one most people have heard of, and the listing I opened shows $5,990, marked down from $6,990. The maker says it holds about 105 gallons, uses a 20-micron filter plus ozone sanitation, and runs on 120 volts at 15 amps with a GFCI outlet and a built-in 15 ft cord. The tech-specs page lists a 1/2 HP chiller, a maximum cool of 39°F, and weights of 175 lbs empty and 1,200 lbs filled.
Drawbacks I can derive from the specs: the warranty is 12 months, the shortest in this group alongside Dynamic and Coldture, and it's a lot of money to have covered for one year. The 39°F floor is two degrees warmer than the 37°F Renu lists for its larger units. The 1,200 lb filled weight means you need a flat, reinforced spot, which is also true of the rest. The page I read didn't give outside dimensions, so measure your gate and doorway before you order.
The 120V/15A requirement is the friendly one. Most of this group shares it.
Renu Cold Stoic 2.0
Renu's cheaper Stoic sells for $9,499 on the page I opened. The maker says it has a 0.25 HP chiller that cools to as low as 39°F, runs on a standard 120V/15A circuit, and draws 450 watts when cooling. Exterior is 70" L x 33" W x 35" H, with 95 gallons filled and a stated maximum of 134. Filtration is described as "advanced filtration and ozone purification" with no micron rating. The warranty is a 5-year limited one.
Drawbacks: it's the smallest chiller in Renu's range (0.25 HP against 0.5 and 0.8 on the other models), and at $9,499 you pay more than for The Plunge for a chiller that is, on paper, half the size. The listed range stops at 39°F, and the spec sheet gives a 37–90°F range, so the two Renu pages don't line up on the low end. That discrepancy is exactly why I'd ask support to confirm before buying. Empty weight is 365 lbs, so plan on two or more people for placement.
Renu Cold Stoic 3.0
The 3.0 is $11,399 on its page. The maker says it has a 0.5 HP chiller, a 37–104°F range, a "dedicated circuit recommended" note on the 120V/15A requirement, and a dual-stage filtration setup with a quick-swap external filter and ozone. Power use is listed at 518 watts cooling and 1,013 watts heating. Same 70" x 33" x 35" body as the 2.0, 365 lbs empty, about 1,155 lbs filled, 5-year limited warranty.
Drawbacks: price, mainly. It costs nearly double The Plunge's listed price and about $4,200 more than the Vero (my arithmetic: 11,399 minus 7,200). The page says free curbside delivery and a ship time of 3 to 5 weeks, which matters if you're trying to beat winter. And the shape is a tall, long chest with an interior of 40" x 25" x 31". I haven't sat in it, so I can't tell you whether that feels roomy, but a 25 inch interior width is something to hold against your own shoulders before you commit.
Renu Vero
This is my pick on paper. The Vero is $7,200 cold-only, or $7,500 for hot and cold. The maker lists a 0.8 HP chiller, 120V/15A on a dedicated circuit, a 37–100°F range, 95 gallons filled, and an "XL filter + ozone" setup with a 50-micron filter. Cooling draws 1,080 watts and heating 1,200. The tub is 42" x 33" x 39" outside, and the maker says it fits users up to 6'6". The warranty is 5 years limited.
Why it stands out: it ties for the biggest chiller Renu lists with a short footprint and a longer warranty than most.
Drawbacks: 1,080 watts on a 15-amp circuit is a heavy load. 120V times 15A is 1,800 VA (my arithmetic), so the chiller alone takes most of what the breaker allows, and anything else on that circuit becomes a problem. That's why "dedicated" matters. The 50-micron filter is coarser than the 20-micron filters listed by The Plunge and Dynamic, though I can't tell you what that means for your water without testing it. I wrote a longer Renu Vero review, including where Renu's own pages disagree on the cooling wattage and filled weight.
Ice Barrel 500 with chiller
Ice Barrel sells the 500 tub with its own chiller as a bundle at $5,749.98. The maker's page lists the 500 at 57.6" x 30.7" x 42.1", 106 lbs empty and about 900 lbs full, and says it fits most people up to 6'9". A retailer listing gives 4'10" x 2'7" x 3'6" and 94 gallons, which matches within rounding. Ice Barrel says its chiller is a 1/2 HP unit with app control, and the warranty is limited lifetime.
Drawbacks: this is the entry where I can tell you the least. The pages I opened didn't list the chiller's voltage, amperage or temperature floor, and the chiller collection page showed it as sold out when I looked. Water treatment is described as a stabilizer accessory, which isn't a filter or ozone system in the way The Plunge's setup is. So the tub is a deep, upright barrel with a mid-range bundle price, and the electrical and filtration questions are the ones to ask before paying.
Dynamic Cold Therapy
The Salus Saunas listing shows a Dynamic cold plunge at $8,495 with a 1 HP motor and 0.8 HP rotary compressor, 120V/15A, a 37–85°F range, and a two-stage filter using 20-micron replaceable filters. Rectangle tub sizes are 50" x 32.5" x 31.5" (small) and 55" x 32.5" x 31.5" (XL), holding up to 135 gallons, with tub weights of 176.5 and 198.5 lbs. Warranty is 1-year limited.
Dynamic also sells the chiller on its own. The Select Fitness page shows the Premier Edition at $3,499 (0.8 HP) or $3,699 (1.0 HP), rated for plunges up to 150 gallons, with ozone and the same 1-year warranty. That's useful if you already own a tub or want a barrel.
Drawbacks: a top temperature of 85°F means this is a cold unit, not a hot-and-cold one. The two pages give different cooling-rate figures (20 minutes versus 30), and the listing's "1 HP motor with.8 hp rotary compressor" wording is confusing, so I'd ask which number governs electrical draw. A one-year warranty at $8,495 is thin.
Coldture Classic with Chiller Pro
At $3,499 on sale ($3,999 regular), this is the cheapest bundle I found. The listing shows a tub that is 63" x 29.5" x 26.3" with 400 L of water (about 106 gallons, my arithmetic: 400 divided by 3.785), a chiller that draws 8A on a standard 15A household outlet, a 37–104°F range, and continuous circulation and filtration. Chiller weight is 66.1 lbs dry.
Drawbacks: the page gives no horsepower, no filter micron rating and no mention of ozone. Both the tub and chiller carry a 1-year warranty. At 26.3" tall the tub is a shallow design, which you may or may not like, and I can't say how it feels. Think of it as the budget end of the cold plunge chiller price range, where you trade documentation and warranty for money.
How to choose a cold plunge with a chiller
Start with the circuit, because it's the one thing you can't fix after delivery. Five of the seven here list 120V/15A, and Coldture lists 8A on a standard 15A outlet. If you can get a dedicated 15-amp line to the spot, any of them works. If the closest outlet is shared with a garage freezer or a pool pump, call an electrician before you click buy.
Then size. Compare interior dimensions to your own height and shoulder width, not the exterior. Renu's Cold Stoic interior is 40" x 25" x 31", and the Vero fits users up to 6'6" per the maker. Capacity matters for two reasons: more water holds temperature better, and it weighs more. Filled weights here run from about 900 lbs to 1,200 lbs.
Indoor versus outdoor. Plunge's All-In model states indoor or outdoor use, and the others are mostly sold for backyards. Indoors, a chiller dumps heat into the room and a 1,000 lb tub needs a floor that can take it. Outdoors, check the stated operating temperature range with the seller, because I found none listed on the pages I opened.
Filtration. Ozone shows up on The Plunge, Renu and Dynamic. A filter micron rating (20 for Plunge and Dynamic, 50 for Vero) tells you what the filter catches on paper and says little about your water. Whichever you choose, read the maintenance steps first.
Running cost. Renu lists cooling draw: 450 W (2.0), 518 W (3.0), 1,080 W (Vero). As a formula: watts divided by 1,000, times hours running, times your electricity rate. For example, 518 W for 6 hours at an assumed $0.18 per kWh is about $0.56 a day (my arithmetic, and both the 6 hours and the rate are placeholders, not measured figures). Look up your own rate, and treat the hours as a guess until you've watched your own setup. A dedicated running-cost breakdown is the separate guide on cold plunge electricity cost.
Warranty. Five years (Renu) against one year (Plunge, Dynamic, Coldture) is the biggest gap in the table. A chiller is the part most likely to be expensive to fix, so weigh it.
Frequently asked questions
How much does a cold plunge with a chiller cost?
Among the seven I checked, the shown prices range from $3,499 (Coldture sale price) to $11,399 (Cold Stoic 3.0). Stand-alone chillers cost less: Dynamic lists them from $3,499 and Renu lists a 1/4 HP unit at $500. Prices move, so check the page.
Do I need a 240V circuit?
Not for these. Every tub here lists a 120V circuit. Ice Barrel's chiller electrical specs weren't on the pages I opened.
Can I add a chiller to a tub I already own?
Yes, for some. Dynamic sells chillers rated for plunges up to 150 gallons, and Renu sells a standalone 1/4 HP chiller. Check your tub's fittings and volume against the chiller's flow requirements.
Is a cold plunge safe for everyone?
No. Cleveland Clinic advises talking to your healthcare provider first and lists heart disease, high blood pressure, diabetes and pregnancy among the situations to avoid it. I'm not a doctor, so ask yours.
What's the best cold plunge tub if I only have one outlet?
Any 120V/15A tub works, but pick one with a lower draw if the outlet is shared. On Renu's own numbers the 3.0 draws 518 W cooling and the Vero 1,080 W.
What I would do
If I were buying a cold plunge with a chiller for a backyard today, I'd shortlist the Renu Vero and The Plunge. The Vero for the 0.8 HP chiller, the 37°F floor and the 5-year warranty; The Plunge if $5,990 is the ceiling and you accept 12 months of coverage. I'd skip the Cold Stoic 3.0 unless you want the longer tub, since you pay roughly $4,200 more than the Vero for it. Before paying anything, I'd get a dedicated 15-amp circuit confirmed by an electrician and ask the seller in writing for the operating temperature range, the filter type, and the cooling time to 39°F from your tap water. Check with your doctor first.
