Our verdict
The Ice Barrel 300 is a 77 gallon insulated barrel you sit upright in, and most owners say it holds cold well. Buy it if you are under about 5 ft 10 in, or 6 ft and content to sit with your head out. Its lifetime warranty is capped at three years.

What this review is based on
We have not used the Ice Barrel 300. This review is research-based. The specs are the maker’s, read on icebarrel.com on 13 October 2026, and the warranty terms are from its warranty and support pages, read on 5 October. The owner reports come from twenty threads on the r/coldplunge forum that name the 300, dated 2023 to 2026. About twenty owners in them describe their own barrel.
It sits beside the larger 500 on our page about cold plunge barrels, and our picks across every type are in the best cold plunge tubs.

The barrel is sold on Amazon, whose prices we do not print. It sits in our middle price band, $300 to $1,500.
The maker’s filled weight checks out. 77 gallons at 8.34 lb a gallon is 642 lb of water, and the barrel adds 61 lb, which makes 703 lb.
Will you fit?
The maker says the 300 “comfortably fits most body sizes up to 6’ tall”, and that above that “knees may sit above the waterline”. Owners put the comfortable limit a little lower.
| Owner | What they say |
|---|---|
| 5 ft 4 in | “The perfect size”, and easy to get in and out of without a step |
| 5 ft 9 in | The water just covers the shoulders. Can barely get the head under |
| 5 ft 10 in, 185 lb | Enjoys it, and likes the upright position |
| 6 ft | Sits comfortably with the water at the jawline |
| 6 ft, 220 lb | Water to the neck with ease, and can go fully under |
| 6 ft | Cannot work out how to get the head under |
| 6 ft 2 in, 215 lb | Tried one. Sank deep with legs crossed, and had to kick the feet out to get the head under. Bought the 500 |
Read down that column and the pattern is plain. Everyone fits to the shoulders. Getting your head under is awkward at any height, and two owners describe leaning back with their feet up to manage it. Two commenters who own other Ice Barrels say the 300 is too small at 6 ft or over.
If you are near the limit, decide what you want from it. Upright to the neck, it works at 6 ft. Fully under, it works best below about 5 ft 10 in.
Maker says, owners say
| Maker says | Owners say | |
|---|---|---|
| Holding cold | Foam insulation “helps keep your water colder for longer, especially in warm weather” | Nine owners praise it. One lost about 2°F a day through a Montana winter. Another found the water under 55°F after two days above 90°F. Four are less impressed in summer heat |
| Fit | “Comfortably fits most body sizes up to 6’ tall” | Two 6 ft owners are comfortable. A third cannot get their head under, and a 6 ft 2 in owner moved to the 500 |
| Getting in | At 30.5 in, “easy to step in and out without needing a step stool” | A 5 ft 4 in owner agrees |
| Chiller | “Tool-free connection to a compatible chiller” | Owners run it with chillers from four other makers. Two say the drain valve is too narrow for a chiller loop and swap it |
| Build | “Designed to hold up to years of daily use” | A year outdoors under cover and “doing great”, by one owner. One barrel arrived scratched and chipped |
What owners complain about
Owner reports From twenty r/coldplunge threads
- It is small. The fit table above is the main complaint. A self-described big owner in Florida, who rates it the best insulated of his five tubs, still calls it “a little tight sometimes”.
- Summer heat gets through. Four owners. One, in a thread about the 300, says that before he had a chiller the water was in the high 70s a day after a 55°F plunge. Another says it “doesn’t hold temp as well as I wanted in a Texas summer garage”. Two say a small chiller struggles to keep up in the 90s.
- Scratches on arrival. One buyer’s new 300 came with scratches and small chips in the lid and the barrel. Support was slow to answer and gave a small credit. Two owners of the 500 in the same thread describe the same.
- The drain valve is narrow. Two commenters say it restricts the flow once a chiller is plumbed in, and replace it with a full-port valve.
- The lid does not lock. A parent of a toddler asked how to secure it. Owners suggested an appliance strap, and one says the fitted cover is snug enough to be hard to pull off.
- One-offs. A seal on the bottom of an early barrel, which the maker replaced quickly. Condensation under a barrel on a garage floor in humid weather, for which commenters suggest a rubber mat.
Nobody in these threads reports a barrel that cracked, leaked through the wall or failed. One commenter says the barrels “fade and crack over time in the sun” without saying it happened to his. The maker’s own warranty says the plastic fades in sunlight and that fading is not covered.
On ice, and with a chiller
A 77 gallon barrel needs less ice than a 100 gallon pod. From 60°F tap water to 50°F is 40 lb, by our maths, which is four 10 lb bags. At three sessions a week and $3 a bag that is about $1,870 a year if you start from tap water every time.
You will not. The point of the insulation is that yesterday’s water is still cold. One owner brought his down to about 50°F on the first night with home-made ice, left for two days of 90°F weather, and came back to water under 55°F. After that it gained 1 to 2°F a day. The sums are in how much ice an ice bath needs.
Most owners in these threads add a chiller.
- What comes with the barrel: two ports, two bulkheads and seals, a plug for the top port and a pre-filter. The lower port doubles as the drain.
- What size: several owners say a 1/4 HP is enough for a barrel this well insulated. One runs a 1/4 HP through summers above 100°F. Another runs a chiller four hours a day in New England and holds 46°F.
- In heat: two owners find a 1/4 HP or a 1/2 HP working hard in the 90s. If the barrel will stand in hot sun, size up.
- Other makers’ chillers: the maker’s support page says it “can’t confirm compatibility with third-party chillers” and that they “are used at your own discretion”. Owners use them anyway.
The chiller most of them choose is covered in our Active Aqua chiller review. The maker’s own is in our Ice Barrel chiller review, and the rest of our picks are in the best cold plunge chillers.
Will the floor hold?
The maker says the 300 suits “apartments, small balconies, and other limited spaces”. The width fits. The weight is the question.
- 700 lb Filled, by the maker
- 900 lb at most With a 200 lb person in it
- 6.9 sq ft Its outline on the floor
- About 131 lb On each square foot
The first figure is the maker’s. The rest are our maths, for a circle 35.5 in across.
That is more weight on each square foot than the larger 500, because the 300 stands on a smaller circle. An owner who measured his found the base narrower still, at about 32 in.
Winter
Owners leave it outdoors through hard winters. One in Montana filled his at 50°F in November and found it at 42°F six days later. One in Ohio used his all winter and broke through the ice on top in the coldest weeks. One in the Pacific Northwest ran a pump through weeks in the 20s with no trouble.
Two cautions. The warranty excludes damage from “exposure to weather (including freezing)”, so a barrel that splits in a deep freeze is yours to replace. And the chiller is the fragile part: one owner’s froze and burst inside. Disconnect and drain a chiller before the first frost, as our guide to an outdoor cold plunge in winter sets out.
The warranty
It is the same warranty as the 500’s, and it is shorter than it sounds. The barrel is sold with a “limited lifetime warranty”, and the maker’s warranty page says “The limited lifetime warranty is limited to 3 years.”
- It covers material defects. You pay shipping and handling on a repair or a replacement.
- It covers the original buyer only. Several owners in these threads bought second-hand, and a second-hand barrel has none.
- It excludes weather damage, freezing included, and fading.
- It excludes “unauthorized modification”. Drilling the barrel for extra ports is that.
The detail, and who owns the company now, is in our Ice Barrel 500 review.
Ice Barrel 300 or 500
Ice Barrel 300
77 gallons in a circle 35.5 in across, 30.5 in high. The maker sizes it for 6 ft and under. It needs less ice, less floor and less chiller.
Ice Barrel 500
94 gallons, 57.6 × 30.7 in on the floor and 42.1 in high. The maker sizes it for 6 ft 9 in, and owners put its comfortable limit nearer 6 ft 3 in. It costs more and holds more.
Height decides it. Under about 5 ft 10 in, the 300 is the better barrel, and a 5 ft 4 in owner who weighed up both is “so glad I went for the smaller one”. Around 6 ft, either works and the 500 has more room. Over 6 ft, the 300 is the wrong tub.
Who should buy it, and who should skip it
Buy it if you are under about 5 ft 10 in, you want a rigid, insulated tub that takes a chiller, and space is short.
Think twice at 6 ft. You will fit to the neck. Whether that is enough depends on how much you want your head under.
Skip it if you are over 6 ft, or you want to lie back. For a first tub to find out whether you will keep at it, a soft pod costs far less, and our Pod Company Ice Pod review covers one.
Common questions
Can you connect a chiller to the Ice Barrel 300?
Yes. It has two 3/4 in NPT ports and comes with bulkheads, seals and a pre-filter. Owners connect chillers from several makers, and two swap the narrow drain valve for a full-port one to improve the flow.
How much does a full Ice Barrel 300 weigh?
700 lb, by the maker, and up to about 900 lb with a 200 lb person in it. That is about 131 lb on each square foot of floor, by our maths.
Can you get your head under in an Ice Barrel 300?
With effort. Owners from 5 ft 9 in to 6 ft 2 in describe leaning back, lifting the legs or kicking the feet out to do it. One 6 ft owner manages it easily and another cannot.
What happened to the Ice Barrel 400?
The 400 was the maker’s earlier barrel, and it was not insulated. Owners in these threads still use them and compare them with the insulated 300 and 500. It is not on the maker’s site now.
