ONLYCARE XXL 135 Gallon Ice Bath Tub: Quick Answer

The ONLYCARE Upgrade XXL is a 135-gallon (511 L) foldable ice bath tub at $49.99 — the cheapest entry point in our tracked roster that includes a cover, a carry bag, and 8 support posts rated to 680 lb. It sets up in a claimed 2 minutes, folds flat for storage, and fits two adults per the manufacturer. The trade-off is that no chiller ports are published, and the cover's "98% cold retention for 5 hours" is a manufacturer claim with no independent verification.

What Do You Get With the ONLYCARE XXL?

A 135-gallon (511 L) tub measuring 35.5 x 29.5 inches, supported by 8 posts rated to a total load of 680 lb, with multi-layer waterproof tear-resistant fabric walls. Per the Amazon listing retrieved August 23, 2026, the tub ships with a temperature-retaining cover, a carry bag, and an easy-flow drainage system. The manufacturer states it sets up in 2 minutes and fits two adults.

The 8-post / 680 lb load rating is worth pausing on. At $49.99, this is a fabric-sided pod — not a rigid barrel — and the support post count and weight rating tell you how the manufacturer solved the structural question. Eight posts distribute the water load across the frame rather than relying on air pressure alone (as a pure inflatable would). The 680 lb figure covers the water weight plus two users comfortably: 135 gallons of water weighs roughly 1,125 lb at 8.34 lb per gallon, so the 680 lb rating applies to the user-plus-post load, not the total filled weight.

The temperature-retaining cover is the only cold-management feature the listing publishes. There are no chiller ports, no insulated walls, and no thermal lid construction details beyond "temperature-retaining." The claimed "98% cold retention for 5 hours" is a manufacturer figure that we treat as unverified — useful as a directional signal, not as a tested spec.

What Makes This the Cheapest Entry Point?

Three things combine to hit the $49.99 price: fabric walls instead of rigid material, no chiller ports, and a claimed 2-minute setup that uses fold-out posts rather than inflation. The ONLYCARE does not need a pump — you unfold it, lock the posts, add water, and drop the cover on.

The trade-off is insulation depth. Fabric walls with multi-layer construction trap some thermal resistance, but they are not in the same class as polyurethane foam-insulated rigid barrels (Ice Barrel 300/500) or double-layer insulated inflatables (Ice Pod Pro). For buyers who plan to fill with ice, that is acceptable — the ice does the cooling work. For buyers who want the tub to hold cold longer between ice top-ups, the insulation story is weaker.

The foldable design with a carry bag is the portability advantage. At $49.99 with a carry bag, this is the tub you take to a cabin, a campsite, or a friend's backyard, fill, use, drain, fold, and leave — not the tub you set up as a permanent backyard fixture.

Does the 135-Gallon Capacity Fit Two Adults?

The manufacturer claims it fits two adults, but the 35.5 x 29.5-inch dimensions are a single-person plunge footprint. Two adults at 35.5 inches wide would be shoulder-to-shoulder at best, and the 29.5-inch depth limits immersion depth. Realistically, this is a one-person tub with enough width to turn and adjust position.

For a genuine two-person cold plunge experience, you need either a larger oval tub (AudaciaGo 216 gal at 59 x 31.5 inches) or a rigid tub with a wider opening (Ice Barrel 500 at 30.7 x 42.1 x 57.6 inches). The ONLYCARE's "fits two adults" claim is technically possible in a shared soak but not comfortable by standard furniture dimensions.

How Does the ONLYCARE Compare With Other Budget Tubs?

| Product | Capacity | Walls | Chiller | Price (research time) | |---|---|---|---|---| | ONLYCARE XXL 135 Gal | 135 gal (511 L) | Multi-layer fabric, 8 posts | None | $49.99 | | Jecoo Ice Bath Tub | not published | Polyester + PVC + pearl cotton | None | $49.99 | | Keystone Peak Portable | not published | 3-layer insulation | None | $44.97 | | The Pod Company Standard 84 Gal | 84 gal (318 L) | not detailed | None | $53.99 |

The ONLYCARE wins the budget tier on published capacity and support specs: 135 gallons and 680 lb load rating with 8 posts, versus competitors that publish less or no capacity/structural data. At the same $49.99 price point, the Jecoo publishes 32 x 32 x 30-inch dimensions and pearl cotton insulation but no capacity figure. The Keystone Peak is cheaper at $44.97 but publishes only 3-layer insulation and a 5-year assurance — no capacity, no load rating, no size data.

The Pod Company Standard is $4 more but holds only 84 gallons and fits users to 6'2" (vs. the ONLYCARE's no-height-limit claim). If you want maximum capacity at minimum spend, the ONLYCARE is the clear pick.

Rating Breakdown (Spec-Based Evaluation)

| Dimension | Score | Justification | |---|---|---| | Cooling performance | 3/5 | The temperature-retaining cover claims "98% cold for 5 hours" (manufacturer figure, no independent test); no chiller ports, no insulated wall construction details beyond multi-layer fabric. | | Build quality | 4/5 | Multi-layer waterproof tear-resistant fabric with 8 support posts rated 680 lb is solid for the price, though fabric-sided pods are less rigid than PVC or LLDPE barrels. | | Value | 5/5 | $49.99 for 135 gal with cover, carry bag, drain, and 8 posts is the cheapest entry point with real capacity in our roster. | | Ease of setup | 5/5 | Claimed 2-minute setup with foldable posts, no pump required; folds flat into an included carry bag for storage or transport. |

Pros and Cons

Pros

• 135-gallon (511 L) capacity at $49.99 — the cheapest entry point with a published volume in our roster.
• 8 support posts rated to 680 lb provide structural stability for a fabric-sided pod.
• Temperature-retaining cover and carry bag included at the base price.
• Claimed 2-minute setup with foldable posts — no pump or tools needed.
• Folds flat for storage and comes with a carry bag for transport.

Cons

• Cover's "98% cold retention for 5 hours" is a manufacturer claim with no independent verification.
• No chiller ports — ice-only cooling; no path to temperature-controlled use.
• Multi-layer fabric walls provide less insulation than foam-insulated rigid tubs.
• "Fits two adults" claim is possible but cramped at 35.5 x 29.5 inches.

Verdict

The ONLYCARE XXL 135 Gal is the best cheap entry into cold plunging for buyers who want real capacity, a cover, and portability without spending more than $50. It is not an insulated premium tub — the fabric walls and unverified retention claims mean you will need ice or a cold water source — but it delivers 135 gallons, 680 lb support, a carry bag, and a claimed 2-minute setup for less than the price of a pair of running shoes. If you want chiller compatibility or long cold retention, step up to the Pod Company Ice Pod Pro ($79). If you want to try cold plunging for the first time at minimum risk, this is the correct starting point.

How We Evaluate

This review is a specification-based evaluation, not a hands-on test. We did not purchase, handle, or measure this product. Every rating, comparison, and claim above is grounded in the Amazon listing data retrieved August 23, 2026 — capacity (135 gal / 511 L), dimensions (35.5 x 29.5 in), support posts (8, rated 680 lb), cover retention claim (98% for 5 hours), setup claim (2 minutes), and price ($49.99). Where the listing does not publish a figure (quantified wall insulation R-value, maximum temperature rating, or independent cold-retention test), we say so explicitly rather than inventing one. Ratings reflect how well the published specifications serve the product's intended use, not measured performance.
