The Plunge
by Plunge
Score
Plunge's original tub — sold for a while as the Evolve XL, now simply The Plunge. Ships with the Pro Chiller Gen 2, a 20-micron filter plus ozone, a 39°F floor and about 105 gallons. Plug-and-play means no chlorine, no ice hauling, just a cold tub waiting.

Buy it if cold exposure is a permanent daily habit and you want near-zero startup friction. Skip it if you plunge under 3x/week or your only space is a freezing garage.
Naming note: Plunge retired the Evolve and Evolve XL names; the Evolve XL product page now redirects to this tub (verified 2026-08-21). The step-up All-In Gen 2 builds a 1 HP chiller into the tub and reaches 37°F.
Roberts et al. (2015, J Physiol) showed regular post-resistance-training cold immersion blunts hypertrophy — separate cold exposure from lifting by 4+ hours; Higgins et al. (2017, BJSM) found it reduces muscle soreness.

Other cold plunges we rate
Ranked alternatives from the same category, with our score and the current price.
The ice-and-go alternative. No chiller, so you buy or make ice. Good insulation keeps a 3-bag ice dump at 45°F for 24 hours.
The gateway plunge. Inflatable, under $100, no chiller. Treat it as a ritual-starter, not a forever tool. Needs ozone and ice management.
The coldest setpoint in the category: a 28°F floor, 150-gallon tub, ozone plus UV sanitation, on a standard 12-amp GFCI plug. The current-generation Pro costs nearly twice what Plunge asks, so it is the pick only if that floor or the Sun Home sauna ecosystem matters to you.
The upgrade pick, now in its third generation. 37°F floor and heats to 104°F for contrast work, 0.5 HP chiller, dual-stage filtration plus ozone, app control, 5-year limited warranty. For buyers who want the most complete spec sheet in the category.
