We Researched & Tested The Best Cold Plunge Tubs, Here Are Our Top Picks

One of our tester's favorite perks of the Plunge was the free in-home delivery. Instead of ditching a crate at your door, the delivery team puts your tub exactly where you want it.

Our tester chose their backyard, as their home didn't have a good space to support the 1000-pound weight of the filled tub.

They tackled the rest of set up on their own and dubbed it a "breeze", as it only required connecting the hoses between the tub and external chiller, filling with water, and plugging into a 110v outlet.

The external chiller then cooled the water to their desired temperature. The chiller only drops the water temperature by 1 to 2 degrees per hour. If that feels too slow, we suggest upgrading to the pro chiller, which is at least three times faster.

Although the Plunge has ozone sanitation to break down contaminants and a 20 micron filter to trap debris, it still requires about the same level of maintenance as a hot tub.

FYI, you should keep your Plunge running 24/7 to reduce water maintenance.

The Plunge is made from a combination of acrylic and fiberglas with a reinforced metal base for added durability.

We felt the materials were sturdy enough for regular outdoor use—even on hot sunny days or much chillier temperatures (like when our tester received the Plunge).

We suggest upgrading to the XL if you're taller than 6 foot to ensure you can fully submerge in the water.

Our 5'11" tester was comfortable, but they felt anyone taller might have consider the regular Plunge a tight squeeze when fully horizontal.

Every Inergize tub ships free and comes with quick connect hoses, a hand debris net, a micron filter, and two covers (a fabric and inflatable one). When deflated, the 25-pound tub fits into an oversized duffle, which makes storage a breeze for city dwellers and hikers alike.

Although you'll only need one person to complete the installation, expect to put in a little legwork—or should we say armwork—to inflate the tub with the included hand pump. Our tester found it took less than 5 minutes to get both the tub and lid inflated.

The tub's modular design is developed for portability, and it's about 30 inches deep. Our testers felt the tub was surprisingly durable once inflated, and it didn't easily move side to side or dip down once filled.

The tub is about 30 inches high, which our 5-foot-4-inches tester felt was a little tall to step in (and would recommend anyone shorter get a step stool).

Inergize reviews show those up to 250 pounds and 6-foot-4-inches tall can fit—but our tester noted her legs were already hitting the edges when stretched out.

While the tub and chiller were packaged very well, there was no in-home delivery or setup. Our testers had to drag both boxes through the house and noted they were extremely heavy.

They chose to set it up on their back porch (see photos) as it’s made with durable military-grade materials (and they didn’t want to put a 6-foot+ tub inside the house). Make sure to place it near an outlet as the chiller needs to be plugged in to work!

Our tester and her boyfriend tackled the entire setup on their own. The tub didn’t come with installation or setup instructions, so it wasn’t the easiest thing to put together. But there weren't too many pieces, so they eventually figured it out. 

When first starting the chiller, it took about 8 hours to get the water to our desired temperature (55 degrees Fahrenheit) in Texas during the wintertime.

But after set-up and using it daily, the chiller doesn’t take nearly as long to reach their desired temperature.

The filter needs to be replaced about once a month, with one to two people plunging each day. Our testers typically plunge once or twice a week in the winter, so they haven't had to change the filter just yet (although a replacement was included in the shipment).

The Sun Home Portable Ice Bath is the longest option on our list at 76.8 inches long. Per the brand, it's long enough to fit those up to 6’8” fully submerged.

Our testers are 5’7” and 5’11”, which means they both easily has enough space in the tub.

In fact, they could even cold plunge together, which makes this unique tub one of the best cold plunge tubs for tall people and couples.

The barrel only weigh 55 pounds when not filled with water, so rolling your bath in place should be a an easy process, per our tester.

Simply use the base to pick you ideal spot, add your barrel, and fill with ice water. The insulated cover will help keep water cool for up to three days before you'll either need to add more ice or dump it out.

Technically the Ice Barrel can be set used both indoors and outdoors—though we think the high water level makes it best suited for outdoor use.

Our tester loved that the Ice Barrel was small enough to tuck into the corner of the garage. Pro tip: Add epsom salts for even more ice bath benefits.

The biggest downside of this (or any) ice bath? You're going to have to pay at least $10 for ice with every refill.

The brand offers a $130 maintenance kit for the Ice Barrel, which includes a few essential accessories, including an 8-ounce bottle of water stabilizer.

Best used in fresh water, the stabilizer helps keep water sanitized for up to 45 days.

A streamlined design comes with major perks; you won't need to replace the Ice Barrel anytime soon.

As long as you use the included UV and water-resistant cover, you can expect the recycled plastic to stick around for a lifetime.

If you're on the taller side, stick with the Ice Barrel 400, which has a longer design that's best for taller folks (and can hold those up to 300 pounds).

If you're shorter or rounder, check out the new design: the Ice Barrel 300. Its larger opening is better suited to heavier folks.

Although the brand offers free curb-side delivery, you'll need some help to get the 350 pound crate to its final location. Prepare to call a Task Rabbit (or a moving company).

Luckily, the chiller is already contained and attached, so you'll just need to plug into a standard 110V outlet to get started.

Features like the filtration system and ozone water purification system ensure the water stays fresh between uses (and keeps water maintenance relatively lowkey).

You'll need to replace the filter every month and test the water to ensure it's up to par. Thankfully, an enclosed lid and active purification means maintenance is relatively simple.

Renu upgraded its cold plunge tub design to have a larger water tank, so it could fit a wider array of body sizes. In fact, it's one of the longest tanks on our list.

If the 5-year warranty doesn't tip you off, this luxury cold water tank is meant to be around for awhile.

Crafted for indoor and outdoor use, Renu tubs are constructed with quality materials, all selected for their ability to withstand harsh conditions and UV rays.

Odin's free shipping delivers the ice bath to your front door—but no further. Although the bath is small enough to fit through a standard doorway, it still weighs about 178 pounds—so make sure you have help at the ready.

We suggest calling the movers and refrigeration experts at the same time to streamline the process.

This tub has all the bells and whistles; it's not only constructed with beautiful cedar wood and stainless steel, but the bath comes with a fully automated filtration and sanitation system that requires minimal upkeep.

You can even add a UV sanitizer for $750 for even less maintenance.

Those over 6-foot can opt for the XL model for extra legroom, while couples hoping to share the tub can upgrade to a dual size.

If you're purchasing for a commercial space—like a spa or gym—we suggest investing in the pro model for another $2,000, which increases the power of the chiller to ensure it's up to the strain of consistent use throughout the day.

With proper care—including cedar wood staining every six months—you should expect your Odin to be around for the long haul.

The brand charges a $1,600 White Glove Delivery, so you can expect to sit back and relax as they set up your new investment.

The hardest part will be picking a spot with a 110V outlet; luckily it can be indoors or outside.

The Morozko Force is self-cleaning with micro-filtration and ozone disinfection to keep the water fresh.

Just expect to clean and replace your filter, depending on how heavily you use the tub.

Another investment option, the Morozko Force is meant to to last. It's constructed with a durable cedar frame with ground fault circuit interrupt (GFCI) protection for improved safety.

The Morozko Cold Plunge tub comes in three sizes available with either a 60-inch, 66-inch, or 72-inch length.

The 72-inch is similar to the Renu Therapy option, which fits those up to 6 foot 7 inches tall.

If you've ever found yourself frustrated while pitching a tent, this one might be a bit complicated. It requires you to build a skeleton to hold up the plastic bath. Otherwise setup is simple: add water and ice to get to your desired temperature.

Those who struggle to follow instructions should go with the Pro model; it comes with an insulated lid that keeps water cool between uses for fewer setups.

If you don't mind dumping and refilling the water regularly, then won't have to worry too much about maintenance.

But if water bills are expensive and you plan to plunge often, we'd recommend that you do some independent research on how to keep the water fresh (you'll find great inspo above).

As mentioned, this design is way sturdier than anything you'd find on Amazon. However it still costs less than $200—so you shouldn't expect this purchase to last forever.

Per the brand, this portable tub should fit a wide range of bodies. While it looks small in photos, it holds a whopping 79 gallons of water (despite the frame weighing less than 7 pounds).
