The MiHigh Cold Plunge Tub brings cold immersion therapy home in a well-built package with a clean design. The Spruce's testing ranks it among the best inflatable options available: a 27.5" tall x 31.5" inner diameter tub holding 92 gallons. Durability and easy setup draw praise, though reviewers note the electric chiller is not included in the base price of $799. Buyers who want an affordable yet effective cold plunge are the fit; anyone on a tighter budget, or without access to electricity for the chiller, is not.

Full review
92 gallons that packs down to 16 pounds
The MiHigh is an insulated inflatable tub: 27.5 inches tall with a 31.5-inch inner diameter, holding 92 gallons, and packing down to 16 pounds alongside a carry bag, hand pump and repair kit. The shell is fiberglass-reinforced PVC with a double wall and an insulated lid, which is what separates it from a single-layer tub, since chilled water holds its temperature longer between sessions. The Spruce ranks it among the better inflatable options on build quality and ease of setup.
The chiller is a separate $1,199 purchase
The $799 price covers the tub alone. The 1/3-horsepower electric chiller, which is what takes the water down to 41 degrees and holds it there without ice, is sold separately at $1,199, bringing a full setup to $1,998. That is the single most important thing to understand before buying: ice-only use works, but it is the mode that scores worst, and the automated cooling is the reason to choose this over a stock tank and a trip to the shop for bags of ice.
The initial chill can take half an hour
Cooling is not instant. Bringing the tub down from ambient takes up to 30 minutes on the first run, so plunges have to be planned rather than improvised, and the chiller is audible while it works. The warranty covers materials and workmanship for six months, which is short for this price bracket and the clearest signal that the chiller, rather than the tub, is the part to worry about over time.
Cheaper than a plumbed plunge, dearer than a tub of ice
Against a rigid plumbed plunge the MiHigh is far cheaper and stores flat; against a stock tank or a basic inflatable pod it costs many times more, and it justifies that only if the chiller is part of the plan. Glamour and The Spruce both place it in the middle tier rather than at the top, and the packed footprint of roughly 31 by 15 by 11 inches still needs a cupboard. Regular users get the money back in convenience; occasional plungers do not.

How it compares
The MiHigh Cold Plunge Tub provides a spacious, insulated experience similar to the Cold Pod Elite Lite but at a lower entry price, though it requires a separate chiller like the Plunge Evolve. Its double-walled construction offers better temperature retention than the single-layer Hydragun Supertub, making it a solid mid-range choice for home setups.
