Plunge vs Redwood Outdoors (2026): Turnkey Tub or Sauna Bundle?

If you are choosing only between these two for the cold side of your setup, pick Plunge if you want one decided, turnkey unit and the widest choice of sizes and budgets. Pick Redwood Outdoors if you are building the sauna side with Redwood too and want one brand, one delivery, and a bundle discount across both.

This is the cold-plunge half of the stack. A full contrast setup is usually sauna plus cold plus, for some people, red light. This guide only covers the cold side. If you are still figuring out how cold fits into heat, read the contrast therapy guide first, then come back here to pick the tub.

One important note up front. Plunge sells both cold plunges and outdoor saunas now. Redwood Outdoors is primarily a barrel and cabin sauna brand that also offers all-in-one cold plunge kits. This comparison is specifically about their cold plunge offerings, not their saunas.

Quick Comparison

The table compares both brands' published ranges from August 2026. We refreshed the original Plunge model's price and specifications on September 25, 2026. Confirm current pricing, shipping, and chiller specs directly before you buy.

Plunge

Plunge is the premium pick on the cold side. The original model pairs an acrylic and fiberglass laydown tub with a separate Pro Chiller Gen 2. Plunge lists 105 gallons of water capacity, cooling to 37°F, and app-controlled temperature. If you value not having to match a tub and chiller yourself, that is the practical benefit here. You still need to plan space, power, drainage and water care.

The tradeoff is price at the top of the range. The lineup is wider than it used to be: the entry Pop-Up and Air lines start around $2,990 and $3,990, the core Pod and original Plunge run roughly $5,500 to $9,000, and the flagship All-In lands at $9,990 plus (as of August 2026). Some of that is the matched equipment and design. Some of it is brand. If "I want it to just work and look good" is your brief, that premium can be worth it. If you are optimizing dollars per cold minute, the entry lines have made that argument easier than it was.

Plunge is the right fit if you want a matched setup and will pay for lower planning effort. It is the wrong fit if you would rather put the flagship-tier money into the sauna or red-light side of the stack. The original tub and chiller were $6,790 on September 25, 2026; check the live price and delivery zone before comparing it with Redwood.

Redwood Outdoors

Redwood Outdoors used to be the build-it-cheaper route, a tub paired with a separately selected chiller for a few thousand dollars combined. That route is effectively gone. The current offering is two all-in-one kits with the chiller included: the Alaskan All-In-One at $6,999 to $7,999 and the step-up Denali at $7,999 to $8,999 (as of August 2026). The standalone Alaskan tub, $2,999 without a chiller, is not currently available. That puts Redwood's cold plunge in the same price band as Plunge's core tubs, not below it.

Redwood is also primarily a sauna kit brand, so if you are building the full stack, there is a one-brand-for-both convenience angle on the heat side, and their sauna plus plunge packages run about $12,199 to $16,699 with a package discount over buying separately. Inspect chiller capacity and noise before you commit, because the chiller is the part that actually determines the experience.

Redwood is the right fit if you are pairing the cold plunge with a Redwood sauna and want one brand and one delivery. It is the harder sell as a standalone plunge purchase now that the price advantage is gone.

Our Take

If you want the cold side largely decided for you, and the budget is there, start with Plunge.

If you are buying a Redwood sauna anyway and want the cold side from the same brand in one order, Redwood Outdoors is the sensible bundle pick, but its all-in-one kits no longer undercut Plunge on price.

Neither is a mistake. But note the change: this used to be a money-versus-effort decision, and it is now a polish-versus-bundle decision at similar money. And remember this is only the cold half. Budget the sauna and any red-light separately so the cold plunge choice does not quietly eat the rest of your stack.

FAQ

Is Plunge worth the extra money over Redwood Outdoors?

The price gap has mostly closed. Plunge's core tubs run about $5,500 to $9,000 and its entry Pop-Up and Air lines start near $3,000, while Redwood's all-in-one kits run $6,999 to $8,999 (as of August 2026). Plunge now covers both the cheaper and the premium end of this matchup, so choose Redwood for the one-brand sauna bundle, not to save money on the plunge itself.

Do I need a chiller with either one?

For year-round or warm-climate use, yes. The original Plunge includes a separate Pro Chiller Gen 2, while Redwood's Alaskan and Denali kits include matched chillers. Both brands also list cheaper tub-only versions for ice-and-water use, so confirm exactly what is included before comparing sticker prices.

Is the cold plunge enough on its own, or do I need the sauna too?

A cold plunge works alone. But most people buying these are building a contrast setup, where heat and cold are paired. If that is you, decide the sauna and budget separately. See the contrast therapy guide for how the two work together, and the home sauna cost guide for the heat-side numbers.

What hidden costs should I check before buying either?

Shipping, the chiller if you buy a tub-only version, water treatment and filters, electrical for the chiller, and a stable, level base. The sticker price is rarely the full project price on the cold side either.

What should I read next?
