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.
1. Ice Barrel 300
No chiller, so you buy ice for every session.
Specifications
- Chiller: none, uses ice
- Chiller bundle: $5,149.98
- Warranty: limited lifetime on the barrel
Today's best deal
$1,150 at Ice BarrelIt'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.
2. Modouge 2.0 All-In-One Cold Plunge
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.
Specifications
- 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

Reasons to buy
- 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
Reasons to avoid
- 1-year base warranty
- Newer brand
- Needs about 6 ft by 3 ft of floor
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.
3. Sun Home Cold Plunge Horizontal
The cheapest way to get a real 1 HP chiller and a roomy 128-gallon tub.
Specifications
- Chiller: 1 HP external chiller-heater
- Capacity: 128 gal
- Coldest: 32°F, depends on room temperature
- Warranty: 1 year
Today's best deal
$4,099 at Sun HomeThe chiller-heater sits outside the tub, so you need extra space and hoses, and the warranty is one year.
4. Nordic Wave Viking Cold Plunge
If you care most about long-term coverage, the Viking is the safer buy.
Specifications
- Temperature: down to 35°F
- Chiller: built in
- Warranty: 5 years tub, 1 year chiller

5. Plunge All-In
The name most people know, with a polished app and a plug-and-plunge setup.
Specifications

How to choose
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.
The 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.
