The 5 Best Cold Plunge Tubs With a Chiller (2026)
The most famous tub costs $9,990. Our top pick costs $5,490, with a stronger chiller and a heater included.
A home cold plunge with a built-in chiller now runs from about $4,000 to $10,000, and the brands with the biggest marketing budgets aren't the ones with the strongest hardware. We pulled the published specs, prices, warranties and return policies for five popular tubs, scored each one on the same five criteria, and ranked them.
The short version: next to the $9,990 Plunge All-In, the $5,490 Modouge 2.0 has a stronger chiller (1 HP vs 0.75 HP), a colder floor (35°F vs 37°F) and a heater Plunge charges $500 extra for.

Modouge 2.0 All-In-One Cold Plunge
Temperature: 35°F to 107°F | Chiller: 1 HP, built in | Capacity: ~105 gal | Filtration: sediment, carbon, ozone, UV-C | Power: standard 110–120V outlet
The Modouge is the only tub here that fits a 1 HP chiller, a heater and four-stage filtration into one unit you plug into a normal wall outlet. It cools to 35°F at about 13.5°F per hour, then heats to 107°F, so the same tub doubles as a hot soak. The app handles temperature, scheduling and filter cycles.
The trade-off is the warranty: one year standard, with two to four years sold as an add-on, and Modouge is a newer name than Plunge or Nordic Wave.
Pros
- Cold and hot in one tub, 35°F to 107°F
- Strongest built-in chiller here
- 4-stage filtration including UV-C
- 30-day returns, 0% financing, HSA/FSA eligible
Cons
- 1-year base warranty
- Newer brand
- Needs about 6 ft by 3 ft of floor
Nordic Wave Viking Cold Plunge
Temperature: down to 35°F | Chiller: built in | Warranty: 5 years tub, 1 year chiller | Versions: Hybrid $5,240, Premier $5,990, XL $7,740
If you care most about long-term coverage, the Viking is the safer buy. Its 5-year tub warranty is the longest in this group, it chills to 35°F, and the Wi-Fi app lets you schedule sessions. It's cold only, with no heater, and guided classes in the app cost extra.
Pros
- 5-year tub warranty
- Chills to 35°F
- Wi-Fi app, ozone treatment
Cons
- No heater
- 1-year chiller warranty
- App classes are a subscription
Sun Home Cold Plunge Horizontal
Chiller: 1 HP external chiller-heater | Capacity: 128 gal | Coldest: 32°F, depends on room temperature | Warranty: 1 year
The cheapest way to get a real 1 HP chiller and a roomy 128-gallon tub. The chiller-heater sits outside the tub, so you need extra space and hoses, and the warranty is one year.
Plunge All-In
Coldest: 37°F | Chiller: 0.75 HP built in | Heater: +$500, to 104°F | Capacity: 105 gal | Returns: 30 days
The name most people know, with a polished app and a plug-and-plunge setup. But at $9,990 it's the most expensive tub here, with a 0.75 HP chiller that bottoms out at 37°F, and the heater is a $500 upgrade.
Ice Barrel 300
Chiller: none, uses ice | Chiller bundle: $5,149.98 | Warranty: limited lifetime on the barrel
No chiller, so you buy ice for every session. It's a cheap way to find out if you'll stick with cold plunging, but Ice Barrel's own chiller bundle costs about $5,150, close to the Modouge with a heater and better filtration built in.
Side-by-side
| Tub | Price | Coldest | Heater | Chiller | Warranty |

*Depends on room temperature, per Sun Home.
What to look for
Chiller or ice. If you'll plunge more than twice a week, ice gets expensive and tedious. A chiller holds the temperature for you.
Built-in or external chiller. All-in-one tubs are easier to place. External chillers can cost less but need more room and hoses.
Filtration. Look for ozone or UV-C on top of a basic filter to keep standing water clean between changes.
Returns. These tubs weigh 200+ lb. Check the return window before you buy.
Bottom line
For most people buying a first chiller tub, the Modouge 2.0 is the best value: the strongest chiller in this group, a heater included, four-stage filtration and 30-day returns, for about $4,500 less than the Plunge. If a long warranty matters more to you than a heater, get the Nordic Wave Viking.
