Costco Cold Plunge Guide 2026: What They Actually Sell + Better Alternatives
By IceColdTubs · Updated September 12, 2026
Quick answer: Costco sells real, entry-to-mid-tier cold plunge gear under two brands: LifeTrend (a Lifesmart Products house brand) makes the Classic Cold Plunge with Chiller System at $899.99 (a 1200W chiller, 105-gallon tub, 37-77°F, no ice needed) and the premium Solitude hot-and-cold combo at $2,999.99; Bestway’s SaluSpa Arctic Ice is a $199.99 ice-only inflatable with no chiller at all. Prices swing hard — the Classic has clearanced as low as $499.97, a 44% drop on the same item — and LifeTrend’s own published specs have a capacity discrepancy worth knowing about before you buy. This guide breaks down what’s actually in each box and when a name-brand tub is the better call.
“Cold plunge Costco” is a search people run expecting a simple answer, and the honest one has some nuance: yes, Costco sells cold plunge equipment, but it’s a warehouse-club house brand (LifeTrend) plus a repurposed inflatable-pool brand (Bestway’s SaluSpa), not the recovery-industry names — Plunge, Ice Barrel, The Cold Pod — covered elsewhere on this site. That’s not automatically a downside, but it changes what questions you should be asking before you buy.

Costco cold plunge, by the numbers
- $899.99: LifeTrend Classic Cold Plunge with Chiller System (item #2024351, model SCS-CLDPB3) list price on costco.com — a 1200W chiller, 105-gallon drop-stitch tub, 37-77°F range.
- $499.97: the same item’s tracked in-warehouse clearance low — a 44% drop off the $899.99 list price on the identical SKU.
- $2,999.99: LifeTrend Solitude integrated hot-and-cold tub (item #1899064, model SCS-SLTD01), down from a $3,999.99 list — cold side to 37°F, hot side to 104°F.
- $199.99: SaluSpa Arctic Ice Cold Plunge Bath list price — no chiller, ice-only, and has clearanced as low as $49.97 in past summer sales.
What’s actually in the box
LifeTrend Classic Cold Plunge with Chiller System ($899.99). This is the one worth taking seriously as a real chiller tub: a 105-gallon rigid drop-stitch tub, insulated cover, dual-stage filtration, and a 1200W chiller rated for a 37-77°F range, per LifeTrend’s own product listing — plug-and-play, no ice required. That puts it functionally alongside budget standalone chiller tubs rather than the DIY ice-and-cooler category. The warranty is where it’s worth reading the fine print: LifeTrend’s 1-year limited warranty on functional parts explicitly excludes outdoor use and commercial use, and warranty claims require the buyer to pay return freight both ways (lifesmartproducts.com/warranty-registration). If you’re planning to keep this outside year-round — the default setup for most home cold plunges — that outdoor-use exclusion is a real gap, not boilerplate.
LifeTrend Solitude ($2,999.99, down from $3,999.99). The step-up model: an integrated two-tub cabinet, one side chilling to 37°F and the other heating to 104°F, so contrast therapy doesn’t require separate equipment. At roughly 3.3x the Classic’s price, you’re paying for the hot side, a larger finished cabinet, and (per LifeTrend’s manual) a more built-out control system — not a fundamentally different chiller.
SaluSpa Arctic Ice Cold Plunge Bath ($199.99). This one is worth a direct correction to how it gets marketed: it’s not a chiller tub at all. Bestway — the same company behind SaluSpa inflatable hot tubs and a long line of pool floats — built this from Fortifiber drop-stitch walls with an insulated Tritech cover and “Polar-Shield” weather defense to stop the liner cracking in cold storage, but cooling is entirely on you: fill it and add ice, the same mechanism as a DIY stock-tank setup (see our DIY cold plunge guide). At its real going rate — often $49.97-149.97 on seasonal clearance, well under the $199.99 list — it’s a legitimate low-commitment entry point. Just don’t compare its price to a chiller tub’s price as if they solve the same problem.
Cold Plunge Tub with Chiller
Why we like it: if Costco's LifeTrend listing is out of stock, sold out at your local warehouse, or you'd rather buy from a brand with a longer track record and warranty, chiller-equipped tubs in this same price class are always in stock on Amazon.

A discrepancy worth knowing before you trust the spec sheet
Independent review site ColdPlungeDaddy ran the numbers on two similarly-sized LifeTrend models — the Alta (77” L x 31.5” W x 30” H, published at 61 gallons) and the Solitude’s cold side (77” L x 33” W x 30” H, published at 96 gallons) — and found the published capacities don’t reconcile with the dimensions: the Solitude’s outer box is only about 4.8% bigger than the Alta’s, but its published capacity is 57% bigger, a gap the extra 1.5 inches of width can’t account for. The review also notes LifeTrend doesn’t publish a cooling rate or chiller/heater wattage for its single-person models, which makes it hard to estimate real-world running costs before buying — the kind of spec gap we flag elsewhere on this site (see our cold plunge cost breakdown for how chiller wattage actually translates into a monthly bill). We’re citing this as one outside reviewer’s arithmetic check, not an independently reproduced lab test, but it’s a legitimate reason to treat LifeTrend’s own gallon and capacity figures with some skepticism rather than as verified engineering specs.
Price volatility: the real reason to shop carefully
| Item | List price | Tracked low | Swing |
|---|---|---|---|
| LifeTrend Classic (#2024351) | $899.99 | $499.97 | 44% |
| LifeTrend Solitude (#1899064) | $3,999.99 | $2,999.99 | 25% |
| SaluSpa Arctic Ice | $199.99 | $49.97 | 75% |
This is a bigger deal than it looks. Unlike Almost Heaven’s saunas at Costco — which hold fairly steady list pricing with occasional 10%-ish promos (see our Costco sauna guide) — Costco’s cold plunge listings have been tracked swinging by 25-75% between online list price and in-warehouse or seasonal clearance on the exact same item number. Practically: if you’re buying online at the listed price, it’s worth a quick search for the item number plus “price” before you check out, since the same SKU has genuinely sold for less than half its list price at different points this year.
When to buy elsewhere
- You want a longer warranty. LifeTrend’s 1-year, outdoor-use-excluded terms are thin next to purpose-built cold plunge brands — the Ice Barrel review covers a rotomolded shell built and warrantied for permanent outdoor installation.
- You want an established chiller track record. Plunge and Renu Therapy have years of recovery-market use behind their chiller performance claims; LifeTrend is a general housewares brand (it also makes WalkingPad treadmills) that added cold plunge to its lineup more recently. Our best cold plunge tubs roundup compares the established names directly.
- You want a specific size or a genuinely tested capacity. With the Alta/Solitude capacity discrepancy above unresolved, if precise water volume matters for your space, our cold plunge dimensions guide covers manufacturer-verified figures for the major brands.
- You want ice-only on the cheapest possible budget. If SaluSpa’s Arctic Ice price ever creeps back toward its $199.99 list without a sale, a comparable inflatable is usually in stock on Amazon at a similar or better price — see our best inflatable cold plunge guide.
The bottom line
- Best reason to buy cold plunge gear at Costco: the LifeTrend Classic is a legitimate 1200W chiller tub at $899.99 (often less on clearance) with Costco’s no-time-limit return policy as a safety net if it doesn’t work out.
- Skip it if: you want outdoor-rated durability, a multi-year warranty, or a brand with an established recovery-market track record — LifeTrend’s 1-year warranty explicitly excludes outdoor use, which is how most people actually run a home cold plunge.
- Don’t confuse: the SaluSpa Arctic Ice ($199.99) with a chiller tub — it’s an ice-only inflatable with no active cooling.
- Always check the price before ordering online — the Classic alone has been tracked at both $899.99 and $499.97 on the identical item number.
If you’re weighing Costco’s LifeTrend against a purpose-built brand, our best cold plunge tubs guide puts the full field side by side, and our cold plunge cost guide breaks down what a chiller actually adds to your electric bill so you can compare total cost of ownership, not just the sticker price. Curious how another warehouse-adjacent retailer stacks up? Our cold plunge at Walmart guide covers the identical Bestway SaluSpa Arctic Ice sold there too, plus a genuinely shorter return window worth knowing about first. And if you’re wondering whether the LifeTrend name shows up anywhere else, our cold plunge at Sam’s Club guide covers a different LifeTrend combo unit — one that’s also sold at Home Depot and Wayfair under two more model names.
