Don't Buy the Wrong Size Cold Plunge!

Why Bigger Isn't Automatically Better

The logic is straightforward once you see it laid out: a larger tub means a larger chiller working harder, and a larger chiller means somewhat more frequent filter attention and higher electricity draw. That's simply physics, not a knock against any specific model — it just means the biggest tub on the market isn't automatically the right one for every household.

None of that makes the larger tub a bad option. It makes it the right option for a specific buyer: someone who wants tandem plunging, has a larger frame, or is outfitting a shared space where multiple people plunge back to back. For most individual buyers and households, though, Maus found the Hybrid and Premier delivered the same core experience with meaningfully less upkeep.

How the Three Viking Tubs Compare

The Ice Barrel Problem: Why "Roomy" Isn't Always Roomy

Before getting into the Viking lineup itself, Maus spent real time on a direct competitor: the Ice Barrel 500, one of the most widely purchased cold plunge tubs on the market. On paper, it looks like it should offer plenty of room. In practice, he found the opposite.

The issue comes down to a single design choice: a built-in bench seat molded into the bottom of the barrel. That bench eats up a large percentage of the interior floor space — space that, in a true barrel-style tub, should be usable for standing or crouching submersion. For a user over six feet tall, Maus found he had to twist and angle his body just to get his shoulders under the waterline, rather than simply stepping in and crouching down naturally.

It's a subtle flaw that doesn't show up in spec sheets or marketing photos, but it's exactly the kind of thing that separates a tub that looks big from a tub that actually functions at that size. Maus was direct about it: the design hasn't changed in years, and he doesn't understand why. It's the kind of fix that would meaningfully improve the product without changing its footprint at all.

The Hybrid: Small Footprint, Full-Depth Plunge

The Viking Hybrid is the smallest of the three tubs by water volume, and Maus specifically called out that it's underrated — a model he thinks deserves more attention than it typically gets. It uses a fabric lid that folds away rather than a rigid cover, and the interior combines a vertical wall on one side with a gently slanted wall on the other, letting the user choose between a more upright crouch or a slightly reclined position.

Despite the compact basin, Maus confirmed there's no interior bench and no jets positioned to hit the body from either side — meaning a full submersion is still possible, just with a fraction of the water volume of the larger models. Less water means a smaller chiller, less frequent filter maintenance, and lower electricity draw, which he flagged as a real advantage for anyone tight on space or looking to minimize day-to-day upkeep. He noted that friends who tried it initially assumed it would feel cramped based on its smaller appearance, then were surprised at how much usable room it actually delivers.

The Premier: "Nothing Else Competes"

The Viking Premier is where Maus landed as his own top recommendation, and he was unambiguous about why. Compared side by side with the Ice Barrel 500, the Premier sits taller and has zero interior obstructions — no bench, no molded seating, nothing between the user and a full, comfortable submersion. He described stepping in, crouching down, and going fully underwater without any of the twisting or repositioning the Ice Barrel required.

It's also the tub he uses most often with his own family, noting that it comfortably fits him at 6'1" along with every friend and family member who's tried it, regardless of height. The chiller footprint is smaller than the XL's, which translates directly to less frequent filter changes and lower ongoing electricity cost — a meaningful factor for anyone running a tub daily rather than occasionally.

It's a notable claim coming from someone who has personally tested nearly every cold plunge tub currently sold — Ice Barrel, Polar Monkey, Edge Theory Labs, Plunge, and dozens of DIY builds among them. He made the comparison specifically against the Ice Barrel 500, the tub he'd just spent several minutes critiquing for its bench design — and in that head-to-head, the open-interior Viking Premier came out on top. When asked what he'd buy today if starting from scratch, his answer was immediate: the Premier, specifically because it's not overbuilt for what most single households actually need. (Note: in the video he refers to this model simply as "the Viking" or "the standard Viking" — Viking Premier is Nordic Wave's current name for that same tub.)

The XL: Built for Bigger Bodies and Tandem Plunging

The Viking XL is Nordic Wave's largest offering, and Maus was genuinely impressed by it — spacious enough for two adults to plunge at the same time, a feature few cold plunge tubs on the market offer at all. He described the water level reaching his chest at 6'1", which gives a sense of just how much room the tub has to work with, and described it as a genuine powerhouse: built for capacity and comfort at scale.

His main takeaway wasn't that the XL is difficult to own — it's that it's sized for a specific kind of buyer, and he simply isn't that buyer. At 6'1" and 205 lbs, he doesn't need the extra capacity the XL provides, and he was clear that the tub is genuinely the right call for larger individuals, taller households, or anyone planning to plunge with a partner regularly. The larger water volume calls for a larger chiller, a natural function of scale rather than a drawback — and for the buyer it's built for, that trade is an easy one: real room to move, and the option to plunge with someone else at the same time.

How to Actually Choose Your Size

Maus's framework is simple and worth repeating: don't ask "what fits my body," ask "what fits my life." Most adults up to roughly 250 lbs comfortably fit any of Nordic Wave's three tub sizes. The deciding factors are really about household size, available space, and how much ongoing maintenance — filter changes, water changes, electricity draw — you're realistically willing to manage week to week.

His own conclusion, after testing all three: if he were buying today, he'd choose the Viking Premier. Not because the XL isn't impressive — he was clearly a fan of its power and capacity — but because for a single household without tandem-plunging needs, the Premier hits the balance of full-body submersion, manageable upkeep, and lower running cost better than either alternative.
