The verdict

The Coldture Classic bundle pairs a 400-liter inflatable tub with the Chiller Pro, which Coldture says holds 37°F to 104°F from a standard outlet. It was $3,499 on sale against a printed $3,999, and the tub alone is $999 with no chiller. The catch is a 15% restocking fee and a 1-year warranty that depends on 30-day filter changes and the app.

The trade-off

A return costs a 15% restocking fee, and the 1-year warranty is void if you miss a filter change or lose the app connection.

About this price

Sale price. On Oct 24, 2026, Coldture's US page, with its region set to United States (USD), showed the Classic + Chiller Pro bundle at $3,499. The printed regular price was $3,999, and the page marked it "Save $500" in its Halloween sale. The site banner says the sale ends Oct 30. Coldture's store listing for the bundle still showed $3,999, so confirm the total at checkout. The tub alone is $999 and the PRO Water Chiller alone is $3,499, so the $999 tub price has no chiller in it. A separate VIP Classic + Chiller Pro bundle is $4,499 and adds a care kit. The page also offers a $1,999 plunge price with any sauna in the cart, which isn't deducted. The sale bundle comes with a free maintenance kit, a 3-pack of filters, a dry mat and hose sleeves, which Coldture values at $474. Shipping is calculated at checkout, and the price is before tax.

Running costs: How much does a cold plunge cost to buy and run?

A GOOD FIT FOR

You want a portable chilled tub that runs from a standard outlet and you'll keep up the 30-day filter changes.

You want a chilled tub that deflates for storage and runs from a standard outlet
You'll change a filter every 30 days and keep the chiller connected to the Coldture app
A spot with room for a 63 by 29.5 in tub and a separate chiller box

THINK TWICE IF

You want water colder than 37°F
You need curbside delivery in the US, since Coldture lists curbside for Canada only
You might send it back, since a return costs a 15% restocking fee
A home where you can't keep the chiller connected to the app, which the warranty requires
You need the tub's filled weight before you order, since Coldture doesn't publish it

What still needs checking

The tub's empty weight and filled weight
How long the insulated tub and cover hold the cold
How fast the Chiller Pro cools 400 liters, since the FAQ gives a rate only for the PRO Plunge all-in-one
How many hours a day the chiller runs, since 850 W is an average
The US delivery method and cost for this bundle
The amount of Coldture's administrative fees on a return or late cancellation
Whether the app is free and what Wi-Fi it needs
Whether the tub is inflatable drop-stitch or rotomolded, and whether it carries a 1-year or 3-year warranty
Why the Chiller Pro spec table lists only filtration when its page text describes ozone
What the maintenance kit contains and how often to change the water
Whether the tub or chiller carries an electrical safety listing such as ETL, UL or CSA

Does the Coldture Classic come with a chiller?

Only the bundle does. The Classic tub alone is $999 and has no chiller, while the Classic + Chiller Pro bundle includes Coldture’s Chiller Pro^{1, 2}.

The Chiller Pro sells by itself for $3,499³. The bundle’s printed regular price is $3,999, and it was on sale at $3,499 on Oct 24, 2026¹.

The practical details.

Specifications for Coldture Classic
Exact variant	Classic tub with Chiller Pro bundle (400 liters)
Lowest stated temperature	37°F (3°C) with the Chiller Pro. Coldture's spec table gives a 37–104°F range because the chiller also heats
Water capacity	400 liters (about 106 US gallons), for one or two people
Tub size and weight	160 by 75 by 67 cm (63 by 29.5 by 26.3 in). Empty and filled weight not stated by the manufacturer
Chiller Pro	61.5 by 33.4 by 48.2 cm (24.2 by 13.1 by 18.9 in), 30 kg (66.1 lb) dry. Cooling capacity 2,490 W, heating capacity 3,300 W
Electrical	120 V (rated 110–120 V), 8 A, standard 15 A outlet. Average power draw 850 W. The FAQ recommends a dedicated circuit
Filtration and sanitation	Continuous circulation through a 20-micron filter changed every 30 days. Coldture's bundle and Chiller Pro pages say filtration and ozone cycle the water every 15 minutes, while the Chiller Pro spec table lists only filtration. Chemicals are sold separately
Insulation and cover	Insulated walls and an insulated cover are included. No insulation rating or temperature-hold time is given
Indoor or outdoor	Indoors or outdoors down to 14°F (-10°C). The warranty is void if the chiller is left off below freezing
Controls	Coldture app to set temperature and schedule cycles. The warranty requires the unit to stay connected to the app with current firmware
In the sale bundle	Tub, Chiller Pro, insulated cover and hand pump, plus a free maintenance kit, 3-pack of 20-micron filters, dry mat and hose sleeves
Dimensions	Coldture lists the Classic tub at 160 cm long, 75 cm wide and 67 cm high (63 by 29.5 by 26.3 in). That's about the size of a bathtub. It holds 400 liters (about 106 US gallons) and fits one or two people. The Chiller Pro is a separate box, 61.5 by 33.4 by 48.2 cm (24.2 by 13.1 by 18.9 in). It weighs 30 kg (66.1 lb) dry and 35 kg (77.1 lb) packaged. Coldture doesn't give the tub's empty weight or its filled weight. The water alone is 400 kg, or about 880 lb, at 1 kg a liter.
Materials	Coldture describes the tub as an inflatable made of reinforced 4-inch PVC drop-stitch material, with insulated walls and an insulated cover included. The page gives no insulation rating or hold time. The Chiller Pro is built by Coldture and has continuous internal filtration. Coldture's VIP Classic + Chiller Pro page calls the same Classic tub rotomolded, which conflicts with the inflatable description on the bundle page.

Before you buy

InstallationThe Chiller Pro plugs into a standard household outlet…

The Chiller Pro plugs into a standard household outlet, and Coldture says no special electrical work is needed. The features list says 110–120 V at 13 A. The spec table says 120 V at 8 A on a standard 15 A outlet. Coldture's FAQ recommends a dedicated circuit and GFCI protection for outdoor outlets. Electrical installation is never included in its prices. Coldture says the included hand pump inflates the tub in minutes, and the tub has a hose connection for draining. It's designed for indoor or outdoor use down to 14°F (-10°C). Coldture's policy says curbside delivery is available only in Canada, while white glove delivery covers both countries. White glove places the box on the ground floor and removes the packing, but it doesn't include assembly. The policy doesn't say which method applies to this bundle or what it costs in the US. Shipping is calculated at checkout, and the bundle page says it ships Nov 10.

WarrantyOne year on the tub and one year on the Chiller Pro…

One year on the tub and one year on the Chiller Pro, per Coldture's portable units warranty. Coverage starts at delivery for the original residential buyer. It covers the housing, pumps, chiller parts, heaters, sensors, controls, plumbing leaks and the filtration system against defects. Coldture pays standard ground shipping on approved replacement parts but not labor. The warranty is void if the unit isn't connected to the Coldture app or its firmware isn't kept current. It's also void if filters aren't Coldture's or aren't changed at least every 30 days. Water chemistry has to stay within Coldture's protocols. Leaving the chiller off below freezing, or pairing it with a tub Coldture didn't make without approval, also voids it. A chiller claim has to ship in the original box. Coldture's VIP page says 3 years on the tub, which conflicts with the 1 year on the bundle page. The Chiller Pro page says the warranty can be extended.

Returns30 days from delivery, with a 15% restocking fee…

30 days from delivery, with a 15% restocking fee, per Coldture's shipping and return policy. That's about $525 at the $3,499 sale price. The policy says Coldture covers return shipping when the product is unused, unopened and in original condition, and it may send a prepaid label. The refund policy page leaves that out and says administrative fees can also come off the refund. It doesn't state the fee amount. The chiller has to go back in its original box, and a replacement box costs extra. Refunds arrive within 30 business days after Coldture inspects the return. Cancellation is free until the earlier of 24 hours after you order or shipment. Damage must be reported within 24 hours with photos. A defect or wrong item must be reported within 15 days. The restocking fee doesn't apply to verified defects.

Replacement parts & cost assumptions

Recorded recurring parts and refills:

Premium 20-micron cold plunge filter, 12-pack: $160 every 12 months. Coldture's FAQ says to change the filter every 30 days with Coldture-authorized filters, or the warranty is void. That's about 12 a year, so one 12-pack at $160 lasts a year, or about $13.33 a filter. Singles are $22 and 3-packs are $55. The filter page says it's designed for the Classic with the Chiller Pro. The bundle includes a free 3-pack. On Oct 24, 2026 the filter page showed pre-order with 4 to 6 weeks delivery.
Premium cold plunge chemical starter pack: $100. The pack holds chlorine, an oxidizer, alkalinity plus and test strips. Coldture says water chemistry must be kept to its protocols, but the page doesn't say how long a pack lasts. On Oct 24, 2026 it showed pre-order with 4 to 6 weeks delivery. The bundle's free maintenance kit is valued at $100, but the page doesn't list what's in it.
ColdCare+ quarterly filter delivery: $150. Coldture describes ColdCare+ as a program that ships the right 20-micron filter for your model every quarter. The page lists $150 and doesn't say whether that's per shipment or per year, so it isn't annualized. A quarterly shipment is also less often than the 30-day change the warranty requires.

Purchase is the $3,499 sale price for the Classic + Chiller Pro bundle on Oct 24, 2026. The printed regular price is $3,999, and Coldture's banner says the sale ends Oct 30. The tub alone is $999, and the chiller alone is $3,499.
Installation is unknown. The chiller needs a standard outlet, and Coldture recommends a dedicated circuit but doesn't price adding one. US delivery cost is calculated at checkout and isn't included.
Annual consumables are $160, one 12-pack of 20-micron filters, based on Coldture's 30-day change interval. The free 3-pack in the bundle isn't deducted. Chemicals aren't annualized because Coldture states no use rate, and ColdCare+ isn't included.
Watts are Coldture's 850 W average power draw for the Chiller Pro. Coldture doesn't say how many hours a day the chiller runs, so energy use is unknown.
Other yearly costs are unknown. Coldture lists its app without stating a fee, so they aren't set to zero.

Evidence & sources.

Do cold plunges work? Our evidence review grades the research as Mixed. That grade is about the claim, not about this product.

Manufacturer claimThe price, bundle contents, sizes, capacity, chiller ratings, power draw, temperature range, filtration, warranty, return terms and delivery policy come from Coldture's US pages and policies, checked on Oct 24, 2026.^1–11 It's Coldture's own information, not independent testing of cooling speed, temperature holding, water quality or durability. The pages disagree in places: 13 A against 8 A, 104°F against 105°F, and 1 year against 3 years on the tub. The refund policy page and shipping policy page differ on return shipping.
Manufacturer claimColdture's pages list recovery, circulation and mental clarity benefits of cold exposure. They cite no studies, electrical safety listing or regulatory clearance for the Classic.^{1, 3} These are marketing claims about cold exposure in general, not evidence about the Classic. A listing missing from these pages doesn't prove none exists. Certifier databases and studies of cold-water immersion weren't reviewed here.
