Choose if	You want an all-in-one chilled tub for home use, indoors or out, and you have a dedicated 120 V, 15 A circuit and a floor that can take 1,150 lb.	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	The price depends on a time-limited sale, the base warranty is one year, and running costs are unknown because the product page gives no power draw.	The chiller is covered for only a year, and power costs are unknown because Nordic Wave publishes no power draw.

Exact variant	Gen 2, Cold Only (no heater add-on)	Arctic White with the Gen 2 Pro chiller (0.8 HP, heater included)
Dimensions	Plunge lists the tub at 76.75 L × 31.5 W × 28.75 H in. It weighs 238 lb empty and 1,150 lb filled. Plunge asks for at least 16 in of clearance on the fan side for ventilation. It also wants 12 in at the front for drain access and ventilation, and 4 in on the left side as you face the LED display. Plunge doesn't state interior dimensions.	Outside, it measures 36 W × 30 D × 44 H in. Inside, the spec table lists 32 W × 26 D × 39 H in, but an FAQ on the same page gives 37 in for the height. The floor is 24 × 19 in, and it holds about 95 gallons. The spec table lists it at 60 lb without water and about 904 lb with water. Those figures don't add up, since 95 gallons of water weighs about 790 lb. That leaves about 110 lb of dry weight, not 60. Nordic Wave's online store gives 235 lb for the Pro version and 245 lb for the Elite, without saying what that weight covers. An FAQ on the page says the Classic Viking is 30 in wide and fits through most residential doors. That 30 in matches the tub's depth, not its 36 in width.
Installation	It needs a dedicated 120 V, 15 A circuit. A 7 ft power cord with a GFCI on the end is built in. There's no plumbing: Plunge says all you need to do is fill it with water and plug it in. Standard delivery is curbside, to the driveway or curb. Most customers qualify for free in-home delivery in Plunge's core "In Area" zones. It puts the tub on the first level, unpacks it and removes the packaging. Setup and connection to power aren't included. In-stock units ship within 8 business days in the lower 48 states. Hawaii, Alaska and US territories take an additional 2 to 3 weeks.	Nordic Wave says the chiller runs from a standard 120 V household wall outlet, with no specialized electrical upgrades. It doesn't give amperage, wattage or a GFCI requirement. The page calls setup plug-and-play, with an auto-priming pump, and puts it at 15 minutes. It doesn't say how to fill the tub. You drain it by connecting a garden hose to the bottom valve. It's rated for indoor and outdoor use down to 14°F ambient. At 14°F or below, the FAQ says to drain it and store it somewhere temperature-controlled. Shipping to the continental US is free by FedEx Freight. White Glove delivery is an optional upgrade at checkout, and the page doesn't give its price. It ships in 1 to 2 weeks.
Materials	Plunge says it's built for indoor and outdoor use, and an insulated cover is included. Plunge doesn't say what the tub or shell is made of.	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	The standard warranty is 1 year. During the Fall Plunge Sale, Plunge adds a complimentary 2-year extended warranty, which it values at $299. The product page doesn't give coverage details or exclusions.	The tub is covered for 5 years from purchase and the chiller for 1 year from delivery, against defects in materials and workmanship. The warranty page covers the Viking Cold Plunge System and doesn't name the Premier separately. Coverage is for home use by the original buyer and can't be transferred. You must buy filters from Nordic Wave to keep it. Exclusions include skipped filter changes, poor water care, freezing, voltage fluctuations and misuse. Improper installation or relocation is excluded too, and using a third-party freight forwarder voids it. It must be installed and running within 30 days of delivery, and mold or stagnant water from a delay isn't covered. A chiller repair or replacement costs you a flat $250 for shipping and packaging both ways. Repairs must be done by a Nordic Wave approved technician.
Returns	Plunge offers a 30-day guarantee. It says that if you're not 100% satisfied within the first 30 days, you get a hassle-free return policy, though "some conditions may apply". The product page doesn't state return fees or pickup costs.	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 actually paid, even if the box was never opened. The fee includes return freight. At the $5,990 sale price, that's $1,198. You can cancel within 48 hours of ordering for a full refund if the order hasn't entered fulfillment. After that, a 5% fee applies until it ships, and a shipped order can't be canceled. Refurbished, open-box, floor-model and clearance units are final sale. A defective or damaged unit carries no restocking fee if you report it within 48 hours of delivery. That's shorter than the 7 days the warranty page gives for shipping damage.
