Ice Barrel 300 vs 500: Which Size Should You Buy?
Updated June 2026 · by The Cold & Cedar Team
The Ice Barrel 300 and 500 are the same idea built at two different scales: a tough, upright, ice-based cold plunge that saves floor space. They share the build, the insulation and the cult following — what really separates them is size, comfort and price. Here is an honest, side-by-side breakdown to help you pick the right one the first time.
The short answer
Buy the Ice Barrel 300 if you are average height or smaller, you are tight on space, or you just want the easiest step-in and the lower price. Buy the Ice Barrel 500 if you are tall or broad, or you want room to actually settle into the water with built-in stairs and a proper interior seat. Both are ice-based and chiller-ready, both are fully insulated, and both are built to last — so this decision comes down to one question: does the 300 fit your body and your space, or do you need the room of the 500?

The two barrels, compared
Ice Barrel 300 ~$1,200
The 300 is the one that proves how little space real cold therapy needs. It is low and wide, so you step in without a stool and sit upright on the internal ridge in a footprint barely bigger than a side table — ideal for balconies, garages and tight patios. The fully insulated shell and lid hold the cold well after you have iced it, which matters in warmer climates.
It fits most people up to about 6 feet 2 inches, and there is no built-in chiller, so you add ice each session (or fit a chiller later through the ports). For the lower price and the smaller footprint, it is the value benchmark in the Ice Barrel line — and the right pick for most average-height buyers.
Pros
- Compact, space-saving footprint
- Low, easy step-in — no stool
- Fully insulated for warm climates
- Lower price of the two
- Chiller-ready ports
Cons
- Snug for users over ~6′2″
- No built-in chiller (add ice)
Ice Barrel 500 ~$1,500
The 500 is the Ice Barrel grown up. It is taller and longer, with built-in stairs and an interior seat, and it comfortably fits users up to around 6 feet 9 inches — so big-and-tall plungers can finally drop their shoulders and settle instead of fighting the container. Everything that made the line a favourite carries over: the rugged, weatherproof shell, the insulated lid, the upright soak.
It takes more water and ice to chill, costs a few hundred dollars more, and like the 300 it has no built-in chiller (the ports let you add one). But for anyone the standard size never quite fit — and that is a lot of people — the extra room is money very well spent.
Pros
- Roomy for tall / broad users
- Built-in stairs + interior seat
- Same rugged, insulated build
- Upright, space-smart footprint
- Chiller-ready ports
Cons
- Larger footprint than the 300
- More ice/water to chill
- Higher price; still no chiller
How to choose between them
Your body comes first
This is the single most important factor, and it is the one most buyers underweight. The 300 is rated for users up to roughly 6 feet 2 inches and around 250 pounds, and it has a low internal ridge to sit on that brings you into a comfortable upright position. The 500 stretches that ceiling to about 6 feet 9 inches and gives you genuinely more shoulder and leg room. If you are tall or broad, the 300 will feel like a tight squeeze and the 500 will feel like relief — and a plunge you can relax into is one you will actually keep using.
Space and entry
The 300 is the compact champion: a footprint not much bigger than a side table, low and wide so you step in easily without a stool. That makes it the natural pick for balconies, tight decks and garages. The 500 is a larger unit — taller and longer — but it answers the height question with built-in stairs and an interior seat, so getting in and out is graceful rather than a clamber. Measure your spot before you buy: the 300 tucks into corners the 500 simply will not.
Water, ice and running cost
Because the 500 holds more water — about 108 gallons versus the 300’s 77 — it takes more ice to bring down to temperature and a little longer to chill. Neither has a built-in chiller, so if you plunge often you are buying ice (or running a separate chiller) either way, and that ongoing cost is simply larger with the 500. For occasional users the difference is trivial; for daily plungers it is worth adding to the price gap when you do the maths.
Insulation and climate
Both barrels are fully insulated — barrel and lid — with the lid keeping debris out and the cold in between sessions. That insulation is a real advantage in warm climates, where it helps the water hold its temperature for longer after you have iced it. On this front the two are evenly matched; you are not trading away cold-holding ability by choosing the smaller 300.
Cooling: ice now, chiller later
Here is the part people miss: neither the 300 nor the 500 cools the water for you. They are barrels, not machines. What they do offer is chiller-ready ports, so you can start ice-based and add an Ice Barrel chiller down the line to get automatic, always-ready cold. If you already know you want set-and-forget temperatures from day one, be honest with yourself — a dedicated chiller tub may suit you better than either barrel. See our best cold plunge chillers guide if that is you.
Price
The 300 lists at around twelve hundred dollars and the 500 at around fifteen hundred, so you are looking at a few hundred dollars between them — though both move with sales, so always check the live price. Framed against chiller tubs that run several thousand, both barrels are firmly in value territory. The price gap is real but modest; do not let it push you into a barrel that does not fit you, in either direction.

Frequently asked questions
What is the main difference between the Ice Barrel 300 and 500?
Size and entry. The 300 is the compact one: low, wide and easy to step into, with a footprint about the size of a side table. The 500 is the large one: taller, longer and roomier, with built-in stairs and an interior seat, comfortably fitting users up to around 6 feet 9 inches. Everything else is broadly similar between them, so the decision is really about your body, your space and your budget.
Which one should I buy if I am tall or broad?
The 500. It is built for it. The 300 fits most people up to roughly 6 feet 2 inches and about 250 pounds, but taller and broader users feel boxed in. The 500 gives noticeably more room to drop your shoulders and settle, which makes the cold far easier to sit with. If you have ever felt cramped in a plunge, the extra few hundred dollars for the 500 is the easiest call here.
Do the Ice Barrel 300 and 500 come with a chiller?
No. Both are ice-based, meaning you fill them and add ice to reach temperature, and neither holds a set temperature on its own. The good news is that both are fully insulated and have chiller-ready ports, so you can add an Ice Barrel chiller later to keep the water cold automatically. If you want set-and-forget cold from day one, a dedicated chiller tub is a better fit than either barrel.
Is the 500 worth the extra money over the 300?
It depends on fit, not features, because the two share almost all the same engineering. If you are average height or smaller, or you are tight on space, the 300 is the smarter spend and the easier unit to live with. If you are tall or broad, or you simply want to settle in rather than tuck up, the 500 earns its premium every session. There is no wrong answer here, only the right size for your body.
How much water and ice does each one need?
The 300 holds roughly 77 gallons (about 292 litres) and the 500 holds roughly 108 gallons (about 410 litres). The larger volume of the 500 means it takes a little more water and a little more ice to bring down to temperature, and a touch longer to chill. For daily users that ongoing ice difference is worth factoring in alongside the sticker price.
