Installation and ownership

Fit and placement

Tub	Usable fit	Installed footprint	Loaded weight
Sun Home Cold Plunge, horizontal	Interior 69.3 in long, 19.7 in wide and 24.4 in high	Tub 77.2 in long, 27.6 in wide and 24.4 in high; chiller 21.2 by 15.7 by 21.7 in, with its fan 3 ft from walls and the tub	Tub 15.5 lb and chiller 88 lb. At the published 128-gallon capacity, the water weighs approximately 1,068 lb, for approximately 1,171 lb before the bather
Sun Home Cold Plunge, vertical	Interior 27.6 in by 27.6 in and 35.4 in high	Tub 35.4 in by 35.4 in and 35.4 in high; same chiller, with its fan 3 ft from a wall	Tub 15.5 lb and chiller 88 lb. At the published 106-gallon capacity, the water weighs approximately 884 lb, for approximately 988 lb before the bather
Sun Home Cold Plunge Pro	Interior 47.4 in long, 28.7 in wide and 27.5 in high	34 by 78 by 33 in, with the chiller inside	345 lb dry. At the stated 150-gallon fill, water weighs about 1,250 lb, for about 1,600 lb before the bather
Plunge All-In	Interior not listed on the pages we checked	76.75 in long, 31.5 in wide and 28.75 in high, with the chiller inside	238 lb dry and 1,150 lb with water, per Plunge
Ice Barrel 300	Fits most body types up to 6 ft 2 in and 250 lb, per Rogue Fitness	35.5 in wide and 30.5 in high	61 lb empty and about 700 lb filled with 77 gal

Water weights for the Sun Home tubs are capacity-based calculations at 8.34 lb per gallon, using Sun Home's September 2026 spec sheets. They are not instructions to fill a tub to that level, and they are not floor-load approvals. Every figure excludes the bather.

Power, warranty and water care

Tub	Power and drainage	Warranty	Water care
Sun Home Cold Plunge, horizontal and vertical	Dedicated 120V, 15-amp GFCI circuit with a NEMA 5-15 outlet. The equipment's rated electrical draw is 11 amps. Drains through the outlet hose; no plumbing	Listed as 1+ year	Filtration and ozone. Sun Home's guide says to refresh the water every two to three weeks, rinse the mesh filter weekly and replace the paper filter every two weeks to two months, depending on use
Sun Home Cold Plunge Pro	Standard 120V plug on a dedicated 15-amp GFCI circuit; drain valve at the base; no plumbing	1 year, with 3- and 5-year options sold	Ozone and UV. Replace the filter at least once a month; the water-change interval depends on use and filtration
Plunge All-In	Dedicated 120V, 15-amp circuit; no plumbing, per Plunge	1-year residential limited warranty	20-micron filter and ozone; follow Plunge's water-care instructions
Ice Barrel 300	No power; the built-in drain takes a garden hose	Limited lifetime warranty on materials and workmanship	No filtration; manual water care

How we ranked

We ranked on five things:

1. Chiller or ice. A chiller holds a set temperature with no ice run.
2. Cold and clean. The maker's minimum temperature, and how the water is filtered and sanitized.
3. Evidence. Third-party reviews count for more than a maker's page.
4. Power and placement. The outlet, how you fill and empty it, and whether it can live outdoors.
5. Price. Including the ice you buy if there is no chiller.

The Sun Home Cold Plunge is our best overall pick because its listed price includes the chiller, filtration and ozone treatment, so there is no ice to buy and no water-care equipment to add. Its trade-offs are an inflatable shell and a chiller that sits beside the tub. Compare complete systems with the same included equipment. A lower tub-only price is not directly comparable with a package that includes a chiller and water-care equipment. Shipping, accessories, and installation can also change the final cost.

The premium option against its closest alternative

Factor	Sun Home Cold Plunge Pro	Plunge All-In
Price	$14,599	$9,990 regular; $7,990 advertised on 7 October 2026
Tub	Stainless steel, 150 gal	Fiberglass-reinforced acrylic, about 105 gal
Outside size	34 by 78 by 33 in	76.75 by 31.5 by 28.75 in
Interior	47.4 in long, 28.7 in wide, 27.5 in high	Not listed on the pages we checked
Dry weight	345 lb	238 lb
Cooling and sanitation	Integrated chiller rated to 28°F; ozone and UV	Integrated chiller rated to 37°F; 20-micron filter and ozone
Power	120V, dedicated 15-amp GFCI circuit	120V, dedicated 15-amp circuit
Warranty	1 year, with 3- and 5-year options sold	1-year residential limited

Choose the Sun Home Cold Plunge Pro if a stainless steel tub, UV sanitation in addition to ozone, and a larger 150-gallon tub matter enough to justify about $4,600 more than the Plunge All-In's regular price. Choose the Plunge All-In if a lower price and a lighter unit matter more. Neither recommendation is based on using the lowest attainable water temperature.

The picks

1. Sun Home Cold Plunge: best overall

Price: $3,899 vertical and $4,099 horizontal at regular price; $3,799 and $3,999 on sale on 7 October 2026 | Type: Inflatable tub with a separate 1 HP chiller | Coldest (maker): 32°F

The Sun Home Cold Plunge is a complete chilled system for about $4,000. The price includes the tub, an insulated cover, a hand pump and the chiller, so you get a set temperature with no ice to buy and no water-care equipment to add.

A 1 HP chiller cools the water to a manufacturer-rated 32°F, and Sun Home says it also heats, to 104°F. It filters the water, treats it with ozone and runs from an app. The tub is an inflatable drop-stitch design in a horizontal or a vertical shape, and Sun Home rates both for indoor and outdoor use.

Forbes Vetted names the Sun Home Cold Plunge its best cold plunge tub overall. We have not tested it ourselves.

The trade-offs are an inflatable shell, not a rigid one, and a separate 88 lb chiller that sits beside the tub with its fan 3 ft from walls and the tub. Sun Home's spec sheet lists the chiller at 55 to 60 dB, and we have no comparable figure for the other tubs. It needs a dedicated 120V, 15-amp GFCI circuit with a NEMA 5-15 outlet. The equipment's rated electrical draw is 11 amps. The listed warranty is 1+ year.

Sun Home's maintenance guide calls for refreshing this tub's water every two to three weeks, rinsing the mesh filter weekly and replacing the paper filter on a schedule that depends on use.

Pros

• Tub, chiller, filtration and ozone in one price
• Manufacturer-rated minimum of 32°F
• App control
• Portable, and rated for indoor and outdoor use
• Forbes Vetted's best overall pick

Cons

• Inflatable tub, not a rigid shell
• Separate chiller with hoses to route
• Listed warranty of 1+ year
• We have not tested it ourselves

Verdict: Our best overall pick for a complete chilled system at this price. Choose a rigid tub if you want a hard shell.

2. Sun Home Cold Plunge Pro: premium option

Price: $14,599 on 6 October 2026 | Type: Rigid stainless steel tub with an integrated chiller | Coldest (maker): 28°F

The Cold Plunge Pro is a rigid tub with the chiller built in. Sun Home's product page lists a 28°F minimum, a stainless steel tub that holds 150 gallons, ozone and UV sanitation, and a rating for indoor and outdoor use. The unit is 34 by 78 by 33 in and weighs 345 lb dry.

It runs from a standard 120V wall plug on a dedicated 15-amp GFCI circuit, with no plumbing. Sun Home estimates about 1 kWh a day to hold temperature. That is the manufacturer's figure, not an independent measurement. The warranty is 1 year, and Sun Home sells 3- and 5-year options.

Sports Illustrated and GearJunkie have each reviewed it hands-on, and our own Sun Home Cold Plunge Pro Review goes through the specs. The step-entry Pro Apex holds 180 gallons and costs $15,599.

The 28°F figure is what the equipment can reach, not a recommended bathing temperature. Sun Home's guide says the Pro's water-change interval depends on use and filtration, and it calls for a new filter at least once a month.

Pros

• Rigid stainless steel tub with integrated cooling
• Ozone and UV sanitation
• Standard wall plug and no plumbing
• Rated for indoor and outdoor use

Cons

• $14,599, about $4,600 above the Plunge All-In's regular price
• 1-year standard warranty
• One person at a time

Verdict: Choose the Sun Home Cold Plunge Pro if a stainless steel tub, UV sanitation in addition to ozone, and a larger 150-gallon tub matter enough to justify about $4,600 more than the Plunge All-In's regular price. Choose the Plunge All-In if a lower price and a lighter unit matter more. Neither recommendation is based on using the lowest attainable water temperature.

3. Plunge All-In: best rigid tub under $10,000

Price: $9,990 regular on 7 October 2026, before tax; Plunge was advertising $7,990 that day | Type: Acrylic tub with an integrated chiller | Coldest (maker): 37°F

The Plunge All-In is the complete rigid system to compare first with the Cold Plunge Pro. The chiller, pump and filtration sit inside a fiberglass-reinforced acrylic tub, so there is no separate chiller to place. Plunge rates it to 37°F and says it needs no plumbing. Forbes Vetted names it its best premium tub.

It is 76.75 in long, 31.5 in wide and 28.75 in high, and Plunge lists 238 lb empty and 1,150 lb with water. It needs a dedicated 120V, 15-amp circuit. Plunge's lineup page lists a hot option for $400 more. The warranty is a 1-year residential limited warranty.

Plunge has sold more than one generation of the All-In, and older listings show a different weight and a 20-amp circuit. The figures here are from Plunge's current pages, so check the generation if you buy from a retailer. Our Plunge Cold Plunge Review has more on the brand.

Pros

• Chiller, pump and filtration inside the tub
• Under $10,000 at regular price
• Lighter than the Cold Plunge Pro

Cons

• 1-year warranty
• More than one generation is on sale, so check which you are buying
• Interior dimensions are not listed on the pages we checked

Verdict: Our rigid-tub pick under $10,000: a complete all-in-one system for about $4,600 less than the Cold Plunge Pro at regular price.

4. Ice Barrel 300: best ice-based

Price: $1,149.99 at Rogue Fitness on 7 October 2026, with free shipping to the lower 48 states and a listed ship time of 7 business days | Type: Insulated barrel; no chiller included | Capacity: 77 gallons

The Ice Barrel 300 is our pick for cold water without a chiller. The price covers the insulated barrel and lid, and no chiller is included. It weighs 61 lb empty and about 700 lb filled, and it fits most body types up to 6 ft 2 in and 250 lb, per Rogue Fitness's product guide. It has built-in ports for adding a chiller later and a drain that takes a garden hose.

There is no pump and no filtration, so water care is manual. Ice is the running cost, and the example under running costs shows how to estimate it. Taller users can look at Ice Barrel's larger 500 model. Our Ice Barrel Review covers both.

Pros

• Purpose-built and insulated
• Chiller-ready ports
• Limited lifetime warranty

Cons

• Ongoing ice cost in warm months
• No filtration
• No chiller included

Verdict: The right start if you are testing the habit. Run your own ice math before you call it the cheap option.

Also considered

• The Plunge. Plunge's original acrylic tub with a separate chiller. Its price depends on the tub size, the chiller and the heat option, and we did not configure a package for this update, so it is not ranked. Plunge's help center says the original model empties through a drain valve, with a garden hose if the area cannot get wet.
• Morozko Forge. A US-made ice-making tub that appeared in earlier versions of this guide. Morozko sells several models, and we have not verified a current configuration and price, so it is not included in our present rankings.
• Chest-freezer conversions. Chest-freezer conversions are excluded from these recommendations because a household freezer is not designed or certified as a bathing appliance. This guide focuses on purpose-built cold plunge tubs.
• Inflatable tubs without a chiller. Cheap, portable and ice-dependent. See Best Inflatable Cold Plunge Tubs.
• Compact tubs for apartments. See Best Cold Plunge for Small Spaces.
• Other all-in-one chilled units. See Best Cold Plunge Machines.

What to check before you buy

1. Chiller or container. If a listing under $1,500 names no chiller, compressor or refrigeration unit, it is a container you fill with ice.
2. The minimum is a rating. It is what the equipment can reach under the maker's conditions, not a recommended bathing temperature.
3. The ice math. Price the ice before you call a tub with no chiller the cheap option. Use your own bag size, bag price and refill frequency.
4. Power. The chilled tubs ranked here use a standard 120V outlet. Use a GFCI-protected circuit, and give the chiller its own circuit where the maker asks for one.
5. Filling and emptying. No tub ranked here needs plumbing, but every one has to be emptied. Check where a hose will reach and where the water will go.
6. Floor load. A filled tub can weigh more than 1,000 lb before you get in. Sun Home's setup guide asks for a level surface that can carry the filled weight.
7. Distance from a sauna. Some sauna warranties, including the one on Sun Home's Luminar, are void within 5 feet of a water source. Lay out a contrast setup with that gap.
8. Water care. Follow the maintenance instructions for your exact model, and read them before you buy.

Running costs and upkeep

• Electricity. Sun Home estimates about 1 kWh a day to hold temperature in the Cold Plunge Pro. At an illustrative rate of $0.18/kWh, that is about $5 a month. This is the manufacturer's estimate, not an independent measurement, and your use will vary with the set point, the air temperature and the insulation. The EIA's outlook put the 2026 US residential average near 18 cents per kWh when we checked.
• Ice example. Ice cost depends on local prices, water temperature, insulation, weather, and how often ice must be replenished. Example only: three bags at $5 each, replenished twice a week, cost about $130 per month (3 × $5 × 2 × 4.33 weeks). This is a budgeting illustration, not a measured ice requirement for the Ice Barrel 300. Use your actual bag size, bag price, and refill frequency.
• Water and filters. Follow the maintenance instructions for your exact model. Sun Home's guide calls for refreshing the standard inflatable Cold Plunge's water every two to three weeks, while the Pro's interval depends on use and filtration. Filter schedules also differ by model. Follow the specified sanitation and water-quality checks rather than judging the water by appearance alone.
• Supplies and repairs. Budget for filters, sanitizer and water as well as electricity, and for repairs once the warranty ends. We have not priced those for each tub.

Frequently asked questions

What is the best cold plunge tub?

Our best overall pick is the Sun Home Cold Plunge, listed at $3,899 for the vertical tub and $4,099 for the horizontal. It includes a 1 HP chiller, filtration and ozone treatment, with a manufacturer-rated minimum of 32°F. The Sun Home Cold Plunge Pro at $14,599 is our premium option, the Plunge All-In is our rigid-tub pick under $10,000, and the Ice Barrel 300 is our ice-based pick.

What temperature should a cold plunge be?

There is no single recommended temperature. Start warmer than you think you need and work down slowly. Treat a tub's minimum rating as what the equipment can do, not as a target. Our temperature guide has more.

How long should you stay in a cold plunge?

There is no established dose, so keep early sessions short and build up slowly. Cold water triggers a sudden rise in breathing, heart rate and blood pressure. American Heart Association News reports that this cold shock response stresses the heart and can be dangerous, especially for people with heart conditions. Talk to your doctor first if that is you, and get out if you shiver uncontrollably or feel unwell.

Chilled or ice-based: which is better?

A chiller gives you a set temperature, filtered water and no ice runs. An ice-based tub costs far less upfront, and its ice cost depends on local prices, weather and how often you replenish. A chiller may reduce ice purchases, but whether it saves money overall depends on its added purchase cost, electricity, consumables, maintenance, and how often you would otherwise buy ice.

Is a cold plunge tub worth it?

If you will use it, it can be. At five sessions per week for a year, 260 sessions divide a $4,099 purchase price into about $15.77 per session, before operating costs. Electricity, filters, sanitizer, water and repairs continue after the first year. Test the habit with an ice-based tub if you are unsure.

Can you use a cold plunge indoors?

Yes, if the tub is rated for it. Plan for condensation, ventilation, floor load and a route for the water when you empty the tub. Sun Home rates its tubs for indoor and outdoor use, and Plunge lists the All-In for indoor or outdoor use.

How do you maintain a cold plunge tub?

Follow the maintenance instructions for your exact model. Sun Home's guide calls for refreshing the standard inflatable Cold Plunge's water every two to three weeks, while the Pro's interval depends on use and filtration. Filter schedules also differ by model. Follow the specified sanitation and water-quality checks rather than judging the water by appearance alone.
