Best Cold Plunge With Built-In Chiller in 2026
A built-in chiller means you set a temperature and forget it. No ice runs, no waiting, no inconsistency. The water is cold when you want it, every time. The tradeoff: price ($1,899-$7,000+), electricity cost ($15-50/month), and noise. We compared every chiller-equipped cold plunge by what actually matters: how cold it gets, how fast it gets there, and how much it costs to run.
Quick Answer
What's the best cold plunge with a built-in chiller?
The Plunge All-In ($4,990) has the best chiller system — reaches 39°F reliably, includes ozone filtration, and offers WiFi app control. For half the price, the Arctic Warriors ($2,499) includes a competent chiller that reaches 37°F. The Therafrost Pro ($1,899) is the most affordable chiller option but with a less powerful cooling system.
- Best chiller overall: Plunge All-In — $4,990, 39°F, ozone + WiFi
- Best value chiller: Arctic Warriors — $2,499, 37°F, good filtration
- Most affordable chiller: Therafrost Pro — $1,899, 39°F, compact
Our Top Picks
Plunge All-In
The Plunge's chiller is the benchmark others are measured against. It cools to 39°F consistently, circulates water with flow jets (preventing thermal layering where the water around your body warms up), and the ozone sanitation means the water stays genuinely clean. The WiFi app lets you schedule cooling cycles to save energy — cool down before your morning routine, let it idle midday.
- Set-and-forget temperature control
- No ice needed ever
- Hot tub functionality included
- High upfront cost
- Requires electrical hookup
Arctic Warriors Tub
The Arctic Warriors chiller actually reaches a lower temperature (37°F) than the Plunge, at half the cost. The cooling speed is slightly slower and the filtration isn't as advanced, but for the $2,500 savings, most users won't notice the difference. The chiller runs louder than the Plunge — something to consider for indoor setups near bedrooms.
- Chiller included at mid-range price
- Spacious for taller users
- Good value proposition
- Newer brand, less track record
- Chiller can be noisy
Therafrost Pro
At $1,899, the Therafrost Pro gets you into the chiller game at the lowest price point. The compact design and wheels make it the most practical chiller option for tight spaces. The chiller is less powerful than the Plunge or Arctic Warriors, so it takes longer to reach target temperature and may struggle in very warm environments. But in a climate-controlled space, it performs well.
- Great for small spaces
- Affordable with chiller
- Easy to move
- Smaller capacity
- Less powerful chiller
Buying Guide
Electricity costs
A cold plunge chiller typically uses 100-300 watts while running — comparable to a small refrigerator. Expect $15-50/month depending on your electricity rate, climate, and how cold you keep the water. Insulated tubs with efficient chillers sit at the lower end. Uninsulated tubs in hot climates where the chiller runs constantly sit at the upper end.
Cooling speed matters
A powerful chiller drops from 70°F to 40°F in 3-4 hours. A weak chiller takes 8-12 hours. This matters if you drain and refill regularly. For daily users who keep water in the tub, cooling speed is less important since the chiller maintains temperature rather than cooling from scratch.
Frequently Asked Questions
Typically 100-300 watts while running. Monthly cost ranges from $15-50 depending on your electricity rate, climate, and target temperature. Similar to running a mini fridge.
They produce compressor noise similar to a small refrigerator, typically 40-55 decibels. Premium models like the Plunge are engineered for quieter operation. If placing indoors near bedrooms, check noise specs before buying.
If you plunge 3+ times per week consistently, a chiller pays for itself in 1-2 years vs. buying ice. The bigger value is convenience — when your cold plunge is always ready, you actually use it. The friction of buying and adding ice is the #1 reason people quit cold plunging.
