How it scored
Cooling
10.0/10 · 30%Whether the unit actively chills, and how cold it gets. An ice-only tub is not a self-chilling plunge.
- +6Built-in chiller Apowered chiller included - Cools the water actively, with no need to buy or add ice.
- +2Reaches 45 F or colder B37 F - Reaches at least the 45 F range used in most cold-immersion protocols.
- +2Reaches ice-bath cold B37 F - Reaches 39 F or colder, true ice-bath territory.
Water Care
7.0/10 · 20%Ozone, UV, and filtration that keep the water clean between changes.
- +4Ozone sanitation Bozone - Ozone keeps the water clean between changes.
- +3Filtration / circulation Bfilter + pump - A circulating filter keeps debris out and water clear.
Build & Insulation
10.0/10 · 15%Insulation (holds temperature, lowers running cost) and full-immersion capacity.
- +6Insulated Binsulated shell/cover - Insulation holds temperature and lowers the chiller's running cost.
- +4Full-immersion capacity C105 gal - Large enough for full-body immersion.
Value
4.5/10 · 20%Running cost - the chiller electricity brands rarely put on the box.
- +2.5Chiller running cost vs class A~$360/yr electricity (near class median) - Estimated annual chiller electricity, scored against the chiller-unit median. The cost brands rarely disclose.
- +2Insulation lowers running cost Binsulated - Insulation reduces the electricity needed to hold temperature.
Practical
3.0/10 · 15%Warranty, electrical-safety listing, and plug-and-play convenience.
- +3Plug-and-play Bno manual ice - Runs without hauling and replacing ice.
What to know before buying
- · All-in-one unit with a built-in chiller, so it holds a set temperature without you adding ice. Manufacturer lists a minimum around 37 F.
- · Includes ozone water care, which matters because you sit in the same water across multiple sessions rather than refilling each time.
- · Premium price (around $8,490) reflects the integrated chiller, insulation, and water-care system in one cabinet.
- · Runs on standard household power; budget for ongoing electricity to keep the chiller maintaining temperature.
- · The value here is convenience and temperature hold versus a fill-with-ice tub.
FAQ
- Does the Plunge All-In need ice?
- No. It has a built-in chiller that holds water near 37 F without ice, and in our scoring a powered chiller is what separates a self-chilling plunge from an ice-only tub. It also runs ozone and filtration to keep the 105-gallon water clean between changes.
- What does it cost to run?
- We estimate about $360 a year in chiller electricity, which we score under Value as the running cost brands rarely print on the box. That sits slightly above the chiller-unit median in our set, though its insulated shell helps hold temperature and keep that figure down.
