Cold plunge specs for 21 tubs and chillers
Cold plunge specs for 21 tubs, all-in-ones and chillers, from the makers: capacity, weight, coldest temperature, BTU, horsepower and watts. Free CSV, CC BY.
The short answer
21 models
This is every cold plunge tub and chiller we link to, with the specs each maker states, in one table and one CSV file. The coldest temperature any of them claims is 36°F, and only 4 of the 8 chillers state a cooling capacity in BTU.
What the cold plunge spec dataset holds
One row per model: 10 tubs, 3 all-in-ones that ship with a chiller, and 8 chillers. Every figure comes from the maker’s product page or listing, read on the date in the row. We do not test products, so there are no measured results here, and a figure the maker does not state is left blank rather than estimated.
Prices are not in the file. Every model here is sold on Amazon, where prices move daily, so each row carries a price band instead.
- 21 Models, from 14 brands
- 36–42°F Coldest temperature claimed, chillers and all-in-ones
- 4 of 8 Chillers that state BTU per hour
- 280–1,030 W Power draw, for the 7 chillers that state one

The chillers, and what they say they draw

| Active Aqua Chiller with Power Boost, 1/4 HP (AACH25HP) | 39 | 3.9 | 3,010 | 1/4 | 460 | 4.7 | 120 | 1 year |

| Polar Dive USA V5 Water Chiller | 39 | 3.9 | Not stated | 1/3 | Not stated | Not stated | Not stated | 12 months on the Amazon listing |
| The Pod Company Pod Chiller (Standard) | 41 | 5 | Not stated | 1/3 | 280 | Not stated | 110 | 2 years |
| TURBRO FrostCore F85 | 36 | 2.2 | 9,553 | Not stated | 1,030 | 14 | 110–120 | Not stated |
Maker’s spec, except °C, which is our maths. “Not stated” means the maker’s page gives no figure.
Horsepower is a poor guide to running cost. The two AS ColdPlunge 1/3 HP units state 600 W, while the Penguin Chillers 1/2 HP states 450 W and The Pod Company’s 1/3 HP Pod Chiller 280 W. If you are comparing what a chiller will cost to run, compare watts, and use the chiller sizing calculator for the cooling side.
BTU per hour is the figure that says how fast a chiller pulls heat out of the water, and half the makers leave it out. The TURBRO FrostCore F85 states 9,553 BTU/hr, almost twice the next highest, the Penguin Chillers 1/2 HP at 5,000.
The tubs, by size and weight
| Brand and model | Capacity (gal) | Capacity (L) | Empty weight (lb) | Filled weight (lb) | Cooling | Size | Price band |
|---|---|---|---|---|---|---|---|
| Ice Barrel 300 | 77 | 291 | 61 | 700 | Ice, chiller-ready | 35.5 × 35.5 × 30.5 in | $300–1,500 |
| Ice Barrel 500 | 94 | 356 | 104 | 886 | Ice, chiller-ready | 57.6 × 30.7 × 42.1 in | Over $1,500 |
| Bubplay Ice Bath XL | 105 | 397 | 7.9 | 884 | Ice only | 31.5 × 29.5 × 31.5 in | Under $300 |
| Lifepro NordPod | 102 | 386 | 6 | 857 | Not stated | 36.6 in wide × 29.5 in high, 31.4 in inside | Under $300 |
| The Cold Pod Standard | 85 | 322 | 7.7 | 717 | Ice only | 29.5 in diameter × 29.5 in high | Under $300 |
| The Cold Pod XL | 116 | 439 | 11.2 | 979 | Ice only | 35.4 in diameter × 29.5 in high | Under $300 |
| The Pod Company Ice Pod Pro | 110 | 416 | 8 | 925 | Ice, chiller-ready | 32 in diameter × 30 in high | Under $300 |
| The Pod Company Long Pod | 126 | 477 | 17 | 1,068 | Ice, chiller-ready | 62 × 27 × 21 in | Under $300 |
| VEVOR JC-01 | 90 | 341 | 8.2 | 759 | Ice only | 31.5 in diameter × 29.5 in high | Under $300 |
| VEVOR IB-006 | 216 | 818 | Not stated | Not stated | Ice, chiller-ready | 59.1 × 31.5 × 29.9 in with lid | Under $300 |
Maker’s spec, except litres, which are our maths (gallons × 3.785). Filled weight is the maker’s figure for the two Ice Barrels and our maths for the rest: gallons × 8.34 lb plus the empty weight.
Capacity runs from 77 gallons in the Ice Barrel 300 to 216 in the VEVOR IB-006 inflatable. A filled tub is mostly water, so the floor has to carry close to 8.34 lb for every gallon. How big a cold plunge tub is works through the floor question.

How the data was collected
We read each maker’s product page or Amazon listing between 4 and 13 October 2026. The last_checked column gives the date for each row. The same figures appear in our reviews and buying guides, which is why they are kept in one file. When a maker changes a spec, the review, this page and the CSV change together.
The models are the ones we link to, all sold on Amazon, so this is not a census of the market. Brand-direct models we review, such as the Plunge and Coldture chillers, are not in the file yet. How we review covers how a model gets on the list, and cold plunge brands counts what owners report about each brand, which a spec sheet cannot tell you.
