Best Cold Plunge That Makes Ice in 2026
Most cold plunges chill water to 39-45°F and call it a day. A few actually reach 32°F and generate floating ice. The difference is not just temperature. Ice-making mode creates the authentic ice bath experience that athletes and cold therapy veterans want. It also costs more. Here is who makes ice and whether it is worth it.

Our Top Picks
Sun Home Cold Plunge Vertical
The Sun Home Vertical is the most accessible ice-making cold plunge at $3,799. The 1HP chiller pushes water to 32°F and the ice-making mode creates genuine floating ice for an authentic ice bath. The inflatable design means portability and storage, unusual for a unit this capable. App control lets you schedule cooling cycles. Billboard named it the best inflatable cold plunge of 2025.

Plunge All-In
The Plunge All-In reaches 39°F, which is cold enough for most recovery protocols.

If the visual of floating ice matters less than consistent 39°F water every morning, the Plunge is still the gold standard.
- Set-and-forget temperature control

- Hot tub functionality included
- High upfront cost
- Requires electrical hookup
Buying Guide
Does ice-making actually matter?
For the physiological response, probably not. Your body cannot tell the difference between 35°F water and 32°F water with ice floating in it. The benefits plateau below 50°F. But for the experience, there is something about stepping into a tub with floating ice that a number display on a chiller cannot replicate. It is why cryotherapy centers still use ice. The cold plunge community on Reddit debates this regularly, and the consensus is: ice mode is a luxury, not a necessity.
Energy cost of ice making
Pushing water to 32°F and maintaining ice mode uses significantly more electricity than maintaining 40-45°F. Expect $40-80/month vs $15-30 for standard chiller operation. The compressor runs harder and longer. In hot climates, the difference is even more pronounced.
Frequently Asked Questions
Research suggests 50-59°F for recovery benefits, with diminishing returns below 40°F. Ice-making at 32°F is about the experience, not added physiological benefit. Most cold plunge veterans settle around 45°F for daily use.
No. Only models with dedicated ice-making mode and chillers powerful enough to reach 32°F create actual ice. Standard chillers bottom out at 37-42°F. Sun Home is currently the only brand offering ice-making across their lineup.
