The Plunge All-In Gen 2 bills itself as the world's smartest cold plunge, with a plug-and-plunge setup that needs no plumbing. Experts noted it cools 31% faster using 50% less energy, and it includes ozone sanitation with double filtration. The app sets temperature and tracks sessions. It is designated for residential use only and carries a premium price of $7,990. Home users who want a high-end, smart cold plunge are the fit; commercial or budget-conscious buyers are not.

Chilling and heating from one cabinet
The All-In's distinguishing feature is that it does both ends of the temperature range. Garage Gym Reviews treats the dual climate control as the real selling point, because a tub that will heat as well as chill supports contrast therapy from a single installation rather than requiring a sauna alongside it.
According to Garage Gym Reviews, cooling reaches 37°F without added ice and, with the heater option, the water goes up to 104°F. Plunge's own figures put the second-generation chiller at 31% faster using 50% less energy than its predecessor, which is a manufacturer claim rather than an independent measurement, but the direction of travel is consistent with what owners describe.
Plug it in and fill it
There is no plumbing. The chiller, filtration and ozone sanitation are integrated into the tub, so installation is a matter of positioning it, filling it and connecting power, and the app handles temperature setting and session tracking from there.
Two practical caveats attach to that simplicity. The unit weighs 270 lbs empty, so moving it needs two people and a dolly rather than optimism, and it wants a dedicated electrical circuit, which for some owners meant hiring an electrician before the tub could be used at all.
Cracked plastic and slow warranty claims
The reliability reports are the reason to hesitate. Owners describe cracks appearing in plastic components around the filtration system inside six months of regular use, and others report waiting over a month for a replacement chiller after a fault. The warranty runs a single year, which is short cover for a product in this price bracket with that failure pattern.
Support responsiveness draws mixed accounts, generally positive on ordinary questions and slower on warranty claims specifically. Garage Gym Reviews rates the construction highly, so these reports sit against a professional assessment that found the build sound; the honest read is that the long-term picture is unsettled.
$7,990 against alternatives at a third of it
This is a residential-only product at $7,990, and there are cold plunge kits with comparable core function at roughly a third of that. What the extra money buys is the integrated chiller and heater, the ozone and double filtration, the app control and the absence of any plumbing work.
That is a coherent package for someone who wants contrast therapy at home and treats the equipment as an appliance rather than a project. It is very hard to justify for anyone who only wants cold water, is willing to run a separate chiller, or needs the tub for commercial use, which this model is not rated for.
Strengths
- +Ozone sanitation with double the filtration system
- +Plug-and-plunge setup with no plumbing required, per BarBend
- +App-controlled temperature setting and session tracking
Watch-outs
- −High price point at $7,990 USD
How it compares
The Plunge All In adds app-controlled temperature setting and session tracking, which the Plunge Original's chiller lacks, and the two share an acrylic and fiberglass shell. It cools to 37°F and at 270 lbs without water it is lighter than the 345 lb Sun Home Cold Plunge Pro. It costs far less than the Pro and is for residential use only.
