Best cold plunge tub for home: chiller or fill with ice
For most homes the easiest choice is a tub with a chiller built in: the JUGRFIT 90-gallon holds 37°F with no ice runs, for around 50 cents to a dollar a day in electricity by the maker's own figure. An insulated tub you fill with ice, like the Lifepro NordPod, costs less up front and has ports for a chiller later; a cheap inflatable holds cold for hours on ice alone.
Chiller or ice: the one fact that decides it
Built-in chiller
No ice runs. JUGRFIT's own spec sheet rates its chiller to 37°F, for roughly $0.50 to $1 a day in electricity. Needs its own outlet.
Ice, insulated or inflatable
Cheaper to buy, costs more over time. A bag of store ice runs about $3 to $5, and a daily plunge can use one or two.

4.0 / 5 our spec score
The only chiller kit we found on Amazon with real reviews behind it: 79 reviews at 4.8 stars, sold as one tub-and-chiller unit rather than parts you match yourself. JUGRFIT's own spec sheet states a 1050W chiller down to 37°F, a built-in 40-micron filter, and an IPX4 weatherproof rating. You set a temperature from an app instead of watching a thermometer.
Good
- Holds a set temperature, no ice
- Filter built in
- IPX4, indoor or outdoor
Watch for
- Highest price here
- Needs its own outlet
- Heaviest to move once filled
2Best insulated tub: add a chiller later
Lifepro NordPod ice bath tub

- 80 gal, drop-stitch (maker)
- Cools to
- 37°F to 107°F range (manual); ice cools it, no built-in chiller
- Filtration
- None. Manual: drain and refill every 3 days
- Power
- None. Two ports for an external chiller (maker)
- Price
- $$$ higher price of the picks here
3.3 / 5 our spec score
A rigid drop-stitch tub, the same material as an inflatable paddle board, with two ports for a chiller whenever you're ready. Lifepro's own manual rates it to 37°F on ice alone and calls for draining and refilling every three days. It folds down for storage, unlike a hard-shell barrel.
Good
- Holds its shape
- Chiller ports built in
- Two year warranty (maker)
Watch for
- No chiller or filter included
- Water changes every 3 days
- Smaller than the chiller kit
3Cheapest way to start, ice only

- No stated minimum. Insulated walls and lid hold cold longer (maker)
- Filtration
- None. Drain and refill by hand

- Price
- $$ mid price of the picks here
3.3 / 5 our spec score
An inflatable tub that packs into a carry bag, sized for a garage, patio or apartment. The listing states insulated walls and lid to hold cold longer than a plain kiddie pool, plus ports for a chiller later. No thermometer or chiller included, so cold means whatever ice you put in.
Good
- Lowest price here
- Packs away when not in use
- Chiller-ready ports
Watch for
- No filtration; drain and refill by hand
- Holds cold for hours, not days
- Softer sides than a rigid tub
Also worth a look
- Lifepro NordPod ice bath tub, 102 gal
The same tub line, larger, for a taller frame or more than one person. Same 37°F to 107°F range (manual).
- PLUNGE MAGIC Ultimate XXL, 216 gal
The bigger sibling of our inflatable pick, sized for users up to 6 ft 6 in (maker).
- Plunge Lab Cold Plunge Tub XL, 90 gal
A cheaper insulated tub; 5-layer walls the maker says hold 90 percent of temperature for 5 hours. Fewer reviews than our picks above.
Cold water in a tub is really three purchases: a chiller that holds one temperature, an insulated tub you fill with ice, or a cheaper inflatable you also fill with ice. Which to buy depends on how often you’ll plunge.
Chiller vs ice: what actually holds temperature
A chiller is a small refrigeration unit plumbed to the tub; ice does the same job with no moving parts, but it melts. No maker we checked states how long one fill of ice lasts; that depends on your ice, the room and how often the lid comes off.
On running cost: a bag of store ice commonly runs $3 to $5, and a daily plunge easily uses one or two. JUGRFIT’s own figure of $0.50 to $1 a day in electricity, at the roughly 14.7 cents per kWh Washington pays on average (US EIA, July 2026), undercuts daily ice within a week or two.
Why we didn’t rank a bare chiller unit
We checked six standalone chillers and chiller-tub kits on Amazon before JUGRFIT: two were “Currently unavailable,” the rest sat at 3.1 to 4.1 stars. Ice Barrel’s Amazon listing carries only 10 reviews combined. Plunge, BlueCube, Renu Therapy and Sun Home have no cold plunge product on Amazon with a working buy button; buy those direct from the maker.
Electrical and water safety, from the makers
Lifepro’s NordPod manual sets a hard limit: never plunge longer than 10 to 15 minutes, and get out as soon as you shiver. It warns against any electrical appliance within 6 feet of the tub, or operating one while wet. Sun Home’s own guide calls for GFCI protection on a dedicated circuit, tested monthly. Both rule out use during pregnancy, with a pacemaker or heart implant, or a history of heart or circulatory disease; read your tub’s full list first. We review products; we are not clinicians.

Questions people ask
- Do I actually need a chiller, or is ice enough?
- Ice is enough for an occasional plunge: an insulated tub holds a workable temperature for a few hours before you need more. A chiller earns its price if you plunge often, since it holds one temperature daily with no ice runs, for roughly 50 cents to a dollar a day by JUGRFIT's own figure.
- How cold does a home cold plunge actually get?
- By the makers' own numbers: JUGRFIT's chiller is rated to 37°F, and the NordPod is rated to that same floor on ice alone, given enough of it. A cheap inflatable depends entirely on how much ice you add; no maker we checked states a guaranteed minimum for ice alone.
- What keeps the water from turning green or cloudy?
- Filtration, and how often you change the water. JUGRFIT runs a built-in 40-micron filter continuously. The NordPod and the inflatable have none, so their makers call for draining and refilling every few days and covering the tub between uses.
- What electrical outlet does a chiller need?
- JUGRFIT's spec sheet lists 106 to 127V at up to 6.7A, a standard household circuit, not a dedicated 240V line like an electric sauna. Sun Home's own guide calls for GFCI protection on any chiller circuit, since it sits next to water.
- Where do I put 100 or more gallons of water?
- Check your floor first: a filled 90-gallon tub weighs several hundred pounds, so a garage, patio or basement works better than an upper-floor apartment. Every tub here needs a nearby drain or a hose route out, since you can't carry it full.
