Primal Plunges vs Plunge — common questions
Is Primal Plunges a good alternative to the Plunge?
Yes. Primal Plunges reaches a colder 34°F, includes heat and a 21″ PrimalOS touchscreen, uses 316 stainless valves, and publishes an actual thermal cooling capacity. Matched like-for-like, a Plunge Original tub with the Pro Chiller and heat runs about $7,290, with an LED display and a .75 HP rating. Plunge's edge is that they've been around longer and have an on-site technician network across the 48 states.
Does the Plunge come with heat?
No — on the Plunge Original tub, heat is a +$500 upgrade ($5,590 → $6,090). On Primal Plunges, heat is included and reaches 104°F. (plunge.com, captured 2026-07-24.)
Does the Plunge have a touchscreen?
No — Plunge ships an LED display and a phone holder for your own device. Its app scheduling is marked “sauna only,” so the cold plunge can't be scheduled in-app. Primal Plunges builds in a 21″ PrimalOS touchscreen.
Which cold plunge gets colder?
Primal Plunges reaches 34°F; Plunge lists a 37°F minimum with its Pro Chiller (the lower-priced Standard chiller makes no cold-in-heat claim). Both cool at a similar rate (Primal Plunges up to 11°F/hr; Plunge 10–12°F/hr).
How do the warranties compare?
Both offer a 1-year standard warranty with no charge for parts and labor (Primal Plunges in the continental U.S.; Plunge in the 48 states). Plunge also runs an on-site technician network — the tradeoff is a warranty that voids if the chiller isn't kept app-connected and updated, the filter isn't changed every 30 days, or ice is added while it runs.
