Choose if	You want a portable chilled tub that runs from a standard outlet and you'll keep up the 30-day filter changes.	You have a small indoor or outdoor spot near a standard outlet, and you want cold plunges and warm soaks without an electrician.
Main 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.	The chiller is covered for only a year, and power costs are unknown because Nordic Wave publishes no power draw.
Key specifications	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.

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).

Exact variant	Classic tub with Chiller Pro bundle (400 liters)	Arctic White with the Gen 2 Pro chiller (0.8 HP, heater included)
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.	Outside, it measures 36 W × 30 D × 44 H in. Inside, the spec table gives 32 W × 26 D × 39 H in, but the product page FAQ says 37 in for the height. The floor is 24 × 19 in, and it holds about 95 gallons. The spec table gives 60 lb without water and about 904 lb with water. Nordic Wave says it fits users up to 6 ft 4 in.
Installation	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.	Nordic Wave says the chiller runs from a standard 120 V household outlet with no electrical upgrades, and it gives no amperage, wattage or GFCI requirement. The page calls setup plug-and-play with an auto-priming pump and puts it at 15 minutes. You drain the tub through a garden hose on the bottom valve. It's rated for indoor and outdoor use down to 14°F ambient, and at 14°F or below Nordic Wave says to drain it and store it somewhere temperature-controlled. Shipping to the continental US is free by FedEx Freight, and the product page says it ships in 5 to 7 days (Oct 20). White Glove delivery is an optional upgrade at checkout with no listed price.
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.	Nordic Wave doesn't name the shell material. The walls have 2 in of foam insulation, with an anti-sweat design meant to stop condensation. The floor slopes to a dedicated drain valve. It comes with all-weather steps, a Stay-Cold lid and a 2-month supply of filters. The chiller has a clear filter housing, so you can see the filter.
Warranty	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.	The tub is covered for 5 years from purchase and the chiller for 1 year from delivery, against defects in materials and workmanship, for the original home buyer only. The warranty page covers the Viking Cold Plunge System and doesn't name the Premier separately. You must buy filters from Nordic Wave, and it must be installed and running within 30 days of delivery. Skipped filter changes, freezing, voltage swings and misuse void it. A chiller repair or replacement costs you a flat $250 for shipping and packaging both ways, and a Nordic Wave approved technician must do the repair.
Returns	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.	You have 15 days from delivery to request a return, and only new units qualify. Every approved return is charged a flat 20% restocking fee on what you paid, even if the box was never opened. At the $5,990 sale price, that's $1,198. A defective or damaged unit carries no restocking fee if you report it within 48 hours of delivery.
Unresolved questions	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	Power draw, amperage, and whether a GFCI or dedicated circuit is recommended Cooling and heating rates What the optional guided-routine subscription costs after the 60-day membership Shell material The price of White Glove delivery Whether the $5,990 sale price applies at checkout, since Nordic Wave's online store still shows $6,990, and when the sale ends Whether the tub or chiller carries an ETL, UL or CSA safety listing Whether the interior height is 39 in or 37 in Whether the 60 lb empty weight includes the chiller Whether filters need changing once or twice a month, since the product and filter pages differ Whether ozone is part of the water care, since the product page lists UV and the store description lists ozone
