ONLYCARE Ice Bath Tub 135 Gal Cold Plunge XXL — Inflatable Two-Person Portable Tub with Insulated Cover and Reinforced Shell

The ONLYCARE Upgrade XXL 135 Gal Ice Bath Tub is a portable, heavy-duty cold plunge that fits two adults for at-home or on-the-go recovery sessions.

This inflatable ice bath blends a reinforced multi-layer shell, a thermal-retaining cover, and a simple setup so athletes, trainers, and active people can use cryotherapy-style cold immersion without complex installation. Built to be durable, leak-resistant, and easy to move, the tub is sized for roomy full-body soaks and can also serve as a hot bath. Below are the practical details most buyers ask about before choosing an ice bath tub.

How durable and stable is this cold plunge for regular use?

The ONLYCARE tub is constructed from multiple waterproof, tear-resistant layers and supported by eight reinforced posts to prevent tipping. Its leak-proof assembly and robust materials are made to withstand repeated fills, movement, and outdoor conditions when used as directed.

• Multi-layer waterproof shell for puncture and abrasion resistance
• Eight support posts to hold up to 680 pounds safely
• Leak-proof seams and a dedicated drain for fast emptying
• Durable cover that preserves temperature and protects water

How big is the tub and can two people use it comfortably?

With interior dimensions of approximately 35.5" x 29.5", the Upgrade XXL 135 Gal model offers generous room for two adults or a single user to fully submerge and stretch. Its larger footprint reduces cramped positioning and makes shared sessions or extended recovery soaks more practical.

• 135-gallon capacity for full-body immersion
• Spacious interior suitable for two adults or one user with stretch room
• Also usable for warm baths when preferred
• Compact when deflated for storage and travel

What makes setup, maintenance, and transport easy?

Setup takes minutes: insert support legs, inflate the top ring, fill with ice and water, then cover. Routine maintenance is straightforward thanks to the quick-drain system and wipe-clean materials, while the included carry bag and foldable design simplify transport to events or between storage and use.

• Fast assembly—no tools required
• Easy-flow drainage valve for quick emptying
• Lightweight, foldable design with carry bag for portability
• Low-maintenance surface that rinses and dries quickly

How long does the tub retain cold temperatures and what helps preserve ice?

The insulated cover significantly slows heat transfer, so a properly filled tub can maintain chilled water for hours during use. While exact time varies with ambient temperature and ice amount, the design helps keep water colder longer than an uncovered inflatable tub.

• Thermal-retaining cover reduces warm-air exposure
• Thicker multi-layer walls limit heat exchange
• Best results when pre-chilling water and adding adequate ice
• Monitor water temperature for consistent sessions

Who is this for? The ONLYCARE Upgrade XXL 135 Gal Ice Bath Tub suits serious exercisers, coaches, and anyone who wants a portable, durable cold plunge solution without installing permanent hardware. It’s useful for backyard recovery, gym setups, or travel to events when you need a roomy, reliable tub that packs away easily. If you want a larger, heavy-duty inflatable tub with straightforward setup, thermal protection, and proven stability, this model delivers a practical, transportable option for regular cold-immersion sessions.
