The short answer

30 to 67 in

That is the range of cold plunge dimensions at home. A round tub is 30 to 37 in across and about 30 in high. A long tub is 53 to 67 in long and 27 to 32 in wide. Most hold 77 to 126 gallons and weigh 700 to 1,100 lb once filled.

Cold plunge dimensions, tub by tub

A cold plunge tub is a tub you fill with cold water and sit or lie in, and its size decides three things: where it goes, what it weighs, and whether you fit. The table has the twelve tubs we have specs for. If you want our picks and not the measurements, they are in the best cold plunge tubs.

We have not measured these tubs. Every size and capacity below is the maker’s or the seller’s own figure.

Tub	Footprint	Height	Stated capacity	Empty weight
The Cold Pod Standard	29.5 in round	29.5 in	85 gal	7.7 lb
Bubplay Ice Bath XL	31.5 in round	29.5 in	105 gal	7.9 lb
VEVOR 90 gallon	31.5 in round	29.5 in	90 gal	8.2 lb
The Pod Company Ice Pod Pro	32 in round	30 in	110 gal	8 lb
The Cold Pod XL	35.4 in round	29.5 in	116 gal	11.2 lb
Ice Barrel 300	35.5 in round	30.5 in	77 gal	61 lb

Twelve tub outlines drawn to one scale. Seven round tubs from 29.5 to 36.6 inches across, and five long tubs from 53 to 66.6 inches long, above a six-foot line for scale — Each tub’s outer size as a simple outline, all to one scale. The real outlines differ: this shows the floor each one takes.

Round or long, upright or lying down

A round tub takes about three feet of floor each way, and you sit in it with your knees up and the water at your neck. A long tub takes about five feet by two and a half, and in most of them you lie back.

Choose a round tub if

Floor space is short. Every round tub here fits in a square a little over three feet each way, and the soft ones fold into a bag. You sit upright, so your head stays out unless you duck.

Choose a long tub if

You want to stretch your legs and get your shoulders under without folding up. It needs a clear strip about five and a half feet long, and it holds more water to keep cold.

The Ice Barrel 500 is the exception. It has a long footprint and the tallest sides here, at 42.1 in, and you sit upright in it on a moulded seat. Our Ice Barrel 500 review covers how that works for tall people.

Height matters when you climb in. The round tubs and the Ice Barrel 300 stand about 30 in high, which is a high step over the rim. The Long Pod is 21 in.

The types themselves are compared on our pages about portable ice baths, inflatable cold plunges and cold plunge barrels.

How many gallons a cold plunge tub really holds

Most home tubs state between 77 and 126 gallons. The figure is worth checking, because four of the twelve state more water than their own dimensions can hold.

A round tub is a cylinder, and a gallon is 231 cubic inches. Work out the volume from the stated size and you have the most the tub could hold filled to the brim, with walls of no thickness. The real figure is lower.

Tub	Stated capacity	Most its size can hold
VEVOR inflatable	216 gal	About 155 gal	Overstated
The Pod Company Ice Pod Pro	110 gal	104 gal	Overstated
Bubplay Ice Bath XL	105 gal	100 gal	Overstated
Lifepro NordPod	102 gal	99 gal	Overstated
The Cold Pod Standard	85 gal	87 gal	A brim-full figure
VEVOR 90 gallon	90 gal	100 gal	Plausible
The Cold Pod XL	116 gal	126 gal	Plausible
The Pod Company Long Pod	126 gal	152 gal	Plausible
JUGRFIT tub with chiller	121 gal	176 gal	Plausible

Our maths, from each tub’s stated outer size. The NordPod uses its stated inside width of 31.4 in. The VEVOR inflatable’s outer box holds 241 gallons, and about 155 once its 3.1 in walls and floor are taken off.

The VEVOR inflatable is the one that matters. Its stated 216 gallons is 60 gallons more than the inside of the tub can hold by our maths, so size a chiller or count your ice from 155.

The three rigid tubs pass easily. The Ice Barrel 300, the Ice Barrel 500 and The Plunge state far less water than their outer size would hold, because the walls are thick insulation. That gap is what you pay for.

Remember that you take up room too. A full tub spills when you get in, so the water you plunge in is always less than the stated capacity.

What a full cold plunge tub weighs

Water weighs 8.34 lb a gallon, so the water is nearly all of the weight. A soft pod that weighs 8 lb in its bag weighs over 900 lb on your floor.

Tub	Filled weight	Source
Ice Barrel 300	700 lb	Maker
The Cold Pod Standard	717 lb	Our maths
VEVOR 90 gallon	759 lb	Our maths
Lifepro NordPod	857 lb	Our maths
Bubplay Ice Bath XL	884 lb	Our maths
Ice Barrel 500	886 lb	Maker
The Pod Company Ice Pod Pro	925 lb	Our maths
The Cold Pod XL	979 lb	Our maths
The Plunge	1,020 lb	Maker
The Pod Company Long Pod	1,068 lb	Our maths

Our maths is the stated capacity × 8.34 lb, plus the empty weight. Where a stated capacity is overstated, the real weight is lower. Add your own weight on top.

Two tubs are left out. The JUGRFIT listing gives a weight for the whole kit, not the tub, and its 121 gallons of water alone is about 1,010 lb. The VEVOR inflatable weighs about 1,320 lb at the 155 gallons its size allows.

Will you fit?

Makers give a maximum height for most tubs. Where owners have reported on fit, they are less generous.

Tub	Fits, by the maker or seller	What owners say
Ice Barrel 300	Up to 6 ft	A 6 ft owner sits with the water at his jawline
JUGRFIT tub with chiller	Up to 6 ft 5 in	No reports found
The Pod Company Ice Pod Pro	Up to 6 ft 7 in	A 6 ft 1 in owner calls it cramped. A 6 ft 2 in owner can dunk
Bubplay Ice Bath XL	Up to 6 ft 7 in	No reports found
Lifepro NordPod	Up to 6 ft 7 in	No reports found
The Plunge	Up to 6 ft 8 in	Not read
Ice Barrel 500	Up to 6 ft 9 in	Tight above about 6 ft 3 in on the built-in seat
The Pod Company Long Pod	Up to 6 ft 9 in	No reports on fit
VEVOR inflatable	Up to 6 ft 9 in	No reports found

Makers’ and sellers’ figures as above. Owner reports from the r/coldplunge forum, each from a single owner. The Cold Pod states no height for either tub.

A round tub about 32 in across rated for 6 ft 7 in means that person fits with their knees against their chest. If you are over 6 ft and want to sit comfortably, take the maker’s figure down by a few inches or choose a long tub.

The VEVOR 90 gallon’s listing says it suits people “under 6.9 ft”, then adds “especially medium and smaller frames”. Believe the second half.

Work out any tub’s capacity yourself

You can check a capacity claim in a minute with the size from the listing.

Get the inside size in inches. Use the inside figures if the maker gives them. The outer size gives you a ceiling.
Find the volume. For a round tub, multiply 3.14 by half the width, by half the width again, by the height. For a long tub, multiply length by width by height.
Divide by 231. That is the cubic inches in a US gallon, and the answer is the gallons to the brim.
Take some off. You fill below the rim, and your body displaces water, so you plunge in less than the brim figure.

Take the Ice Pod Pro at 32 in across and 30 in high. That is 3.14 × 16 × 16 × 30, which is 24,115 cubic inches. Divide by 231 and you get 104 gallons, six short of the 110 its maker states.

Once you know the gallons, you know the ice. Our guide to how much ice an ice bath needs has the sum.

Common questions

What size is a standard cold plunge tub?

There is no standard. The common size is a round soft pod about 32 in across and 30 in high holding around 100 gallons. Long tubs run 53 to 67 in.

How much space do you need for a cold plunge?

For a round tub, a square a little over three feet each way, plus room to climb in. For a long tub, a strip about five and a half feet by three. A chiller sits beside the tub and needs floor of its own.

How deep is a cold plunge tub?

Most are 24 to 30 in high, and you fill them below the rim. The Long Pod is the shallowest here at 21 in and the Ice Barrel 500 the deepest at 42.1 in.
