Plunge All-In Gen 2
Plunge's flagship all-in-one: an integrated chiller cools the tub to 37F with no ice runs, plus ozone sanitation, filtration, and app-controlled temperature and timers. Plug-and-plunge setup for indoor or outdoor use.
Plunge Chill 1HP Plus (chiller + tub bundle)
Plunge's value line: a 1HP chiller paired with a 120-gallon insulated inflatable tub, pump, filter, and lockable lid. Cools to 36F - the lowest-cost way to get set-and-forget chilled water from the Plunge brand.
Morozko Forge (Filtered Forge)
The original ice-making ice bath: the Filtered Forge makes its own ice and holds near-freezing temperatures with built-in microfiltration and ozone. Handmade in the USA with a cedar frame - the premium, no-compromise option.
Sun Home Cold Plunge (Horizontal)
A portable inflatable plunge with an integrated 1HP smart chiller that reaches 32F and heats to about 104F for hot/cold contrast in one tub. App control, ozone sanitation, runs on a standard outlet.
Polar Dive Pod + Pro Chiller bundle
A budget-friendly inflatable tub bundled with a 350W chiller that holds 39F, backed by a 1-year warranty and 30-day returns. Ships from Florida and is also stocked at Target and Sam's Club - the easiest sub-$600 chiller setup.
DIY stock-tank setup (Rubbermaid 100-gal)
The classic DIY route: a 100-gallon Rubbermaid stock tank plus bagged ice. No chiller and no filtration, so drain and refill regularly - but it's the cheapest way to start plunging at home.
