Buyer's Guide
Which cold plunges are made in the USA?
Penguin Chillers' Summit is the American cold plunge to buy. We compared eight plunges built in the US on price and on what each price leaves out.
Penguin Chillers' Beyond Cold Summit is the American cold plunge to buy for most homes. Penguin builds the stainless tub and its chiller in Tennessee, and the pair plugs into an ordinary 120V outlet for $6,999.99 with free shipping. We compared eight plunges from seven companies that build them in American shops, from a $1,750 barrel you fill with ice to a $17,000 tub that makes its own. Every one is built here, and none of the makers says where its tub material or its compressor comes from.
Eight American plunges fit in one table
These are the plunges we list, sorted by price, with the coldest water each maker claims and the power each one asks for.
| Plunge | Built in | Coldest (maker) | Power | Price | Not in the price |

| Plunge All-In | Sacramento, CA (assembled) | 37°F (3°C) | 120V, 15A dedicated | $9,990–$10,490 | Delivery far from a major airport |

Makers' list prices and ratings read Oct 10, 2026, before sales tax. Each temperature is the maker's own rating. No maker states where its tub material or its compressor comes from.
Penguin's Summit is the plunge to buy
Penguin sells its chillers on their own too, and the Summit sets a 96-gallon stainless tub on one of its 7,500 BTU units. Penguin rates it from 37°F to 100°F (3°C to 38°C) and says it draws 3.9 amps, so it can share a circuit with the patio lights. The insulated cover and a GFCI come in the price, and shipping is free to the lower 48, per Penguin's page.
The weak spot is water care. Penguin fits replaceable filters and names no ozone or sanitizer system, so you'll be treating the water yourself. Measure the space before you order, too. The tub runs a little over six feet long, and by our math it passes 1,000 pounds once it's full and someone's in it.

An Ice Barrel with Penguin's chiller costs about $4,000
To start cheaper, the Ice Barrel 500 holds 94 gallons in an upright, foam-insulated barrel with a seat and steps built in. Out of the box it runs on bagged ice, and you'll buy a lot more of it in August than in January. Ice Barrel says the barrel is made in the USA from recycled plastic and doesn't name a state.
Penguin sells a $2,199.99 package that fits the Ice Barrel 500, built on its Cold Therapy Chiller, and the two together come to about $3,950. The chiller works on a stock tank or a tub you already own as well. Check the wall first, because Penguin's install kit only fits walls a quarter inch thick or thinner.

Desert Plunge sells the cheapest complete tub
The Desert Plunge Exclusive comes with its chiller for $3,698, plus $260 to ship it anywhere in the continental US. Desert Plunge had it on sale for $3,248 when we checked. Desert Plunge says it builds the plunge in Arizona, and the rotomolded tub comes from Grizzly Coolers, which molds its coolers in Decorah, Iowa. The chiller is a quarter-horsepower Active Aqua unit sold by Hydrofarm, and neither company says where it's made.
A quarter horsepower is a small chiller next to Plunge's three-quarter-horsepower unit, and Desert Plunge asks you to keep the tub out of direct sun. It rates the water down to 39°F (4°C). A filter comes in the box, and ozone costs $399 more.

Plunge carries the tub into your house
The Plunge All-In holds 105 gallons and runs a three-quarter-horsepower chiller rated to 37°F (3°C). Plunge says it holds 37°F even on a 120°F day. Picture it on a Phoenix patio in July, if that figure holds, with the deck boards too hot to stand on. Delivery into your home, with the crate hauled away, is free in most places within about 35 miles of a major airport, per Plunge's page.
Plunge says it assembles its plunges at a warehouse in Sacramento, California, and doesn't say where the shell or the chiller come from. The All-In also wants a dedicated 120V, 15-amp circuit. Plunge runs sales often, and its page showed $7,990 against the $9,990 list price when we checked.

Coldtub and BlueCube build tubs that look like furniture
Coldtub builds the Icepod in Nashville as an acrylic tub inside a wood-clad cabinet, and it says its tubs are made there in full. The Icepod holds 60 gallons, the least of the tubs that list a capacity, and Coldtub says it suits bathers about 5'9" and under. Coldtub points taller buyers to the bigger Icepod Plus. The residential package leaves out the heater, and the tub needs its own 20-amp outlet.
BlueCube welds the DROP from aluminum in Redmond, Oregon, where it says fabrication and final assembly happen under one roof. You stand in it up to your neck, and the chiller and pump hide inside the attached steps. It heats as well as chills, from 41°F to 104°F (5°C to 40°C). BlueCube names Iwaki America for the pump and Balboa for the controls, and it doesn't say who makes the chiller or how many gallons the tub holds.

Morozko's Ice Bath makes its own ice
Morozko Forge hand-builds each Ice Bath to order in Phoenix and says it makes ice, holding the water as low as 32°F (0°C). The 70-inch stainless tub takes two bathers, or one up to 6'8", in a marine-plywood frame. At $16,990 it costs close to $3,000 more than anything else here, and it ships four to five weeks after you order.
Morozko lists a 110V cord with an inline GFCI and doesn't publish the amperage. Ask before you choose the outlet, since the tub may need a circuit to itself.

Every plunge here is built in the US from materials of unstated origin
Each of the seven makers names an American shop or says its plunge is made in the USA. None of them says where its steel, aluminum, acrylic or plastic comes from, or who makes the compressor in the chiller. That puts all eight in our built-in-the-USA tier, defined on the method page. We didn't find a cold plunge whose maker says its main materials are American too.
Penguin and Morozko say they build their cooling systems themselves, in Knoxville and Phoenix. Desert Plunge names the brand of the chiller it buys, and the other tubs leave the chiller's maker unnamed.
Two more makers would qualify. Renu Therapy says it designs and assembles its plunges in Southern California, and we left its Cold Stoic out to make room for Penguin's chiller. Endurance says it controls design and manufacturing in South Carolina, but its page names no town and lists no capacity or temperature.
Plan the floor and the outlet before the tub arrives
Every tub here that publishes a full weight comes in between 800 and 1,180 pounds once it's filled, so check what your deck or slab can carry before delivery day.
Three of the tubs want a dedicated circuit: the Plunge All-In, the Coldtub Icepod and the BlueCube DROP. If there isn't a free one near the spot you've picked, an electrician has to run it.
None of these makers shows a UL or ETL listing for a home plunge. Coldtub calls the Icepod "UL Safety Certified by TUV Standards", which mixes the marks of two separate testing labs. Ask any maker for its listing file number before you buy, because an electrical inspector may ask you for it.
How we chose these plunges
This guide draws on each maker's product and FAQ pages, along with Grizzly Coolers' page on where it builds, all read Oct 10, 2026. Prices are list prices before sales tax. We didn't use owner reviews, and we didn't ask the makers for anything beyond what they publish.
Common questions
- Which cold plunges are made in the USA?
- Penguin Chillers (Tennessee), Coldtub (Nashville), BlueCube (Redmond, Oregon), Morozko Forge (Phoenix), Desert Plunge (Arizona) and Plunge (assembled in Sacramento) all say they build cold plunges in the US. Ice Barrel says its barrels are made in the USA without naming a state. None of them says where its tub material or compressor comes from.
- Is Plunge made in the USA?
- Plunge says its cold plunges are assembled in the US, at its warehouse in Sacramento, California. It doesn't say where the tub shell or the chiller is made.
- Is Ice Barrel made in the USA?
- Ice Barrel says the Ice Barrel 500 is made in the USA from recycled materials, and it doesn't name a state or a plant. The barrel ships without a chiller, so it runs on ice unless you add one.
- Does a cold plunge need a dedicated circuit?
- Some do. Among American cold plunges, the Plunge All-In needs a dedicated 120V, 15-amp circuit, and the Coldtub Icepod and BlueCube DROP each need a dedicated 20-amp circuit. Penguin's Beyond Cold Summit draws 3.9 amps from a standard outlet, Penguin says.
