Nordic Wave Viking Hybrid

Nordic Wave positions the Viking Hybrid as the contrast-therapy option in its Viking fleet: the same 0.8 HP Pro chiller (a 1.0 HP Elite is a $1,000 upgrade) that cools to 35 F also carries outdoor-rated heating to 104 F, so one unit covers cold plunges and warm soaks year-round. The tub holds up to 101 gallons (81 gallons recommended fill) in a 50 by 31 by 34-inch low-profile shell with 2-inch foam-insulated walls, rated for ambient temperatures down to 14 F. FlowSense shutoff protection, an auto-priming pump, and app-based temperature scheduling round out a spec sheet that is unusually complete for the category.

Water care runs through multi-stage filtration with a built-in ozone generator (the page also lists UV filtration among its features), with the brand recommending monthly water changes and monthly filter swaps. What the page does not state is a noise figure in decibels, an energy-consumption number, or the tub's shell material in plain terms, so quietness and running-cost claims rest on the brand's own wording. At the researched sale price of $5,240 (regular $5,990) for the Pro configuration, it undercuts most name-brand hot-and-cold plunges, though the chiller itself is only covered for one year.
