Plunge
Cold plunges that behave like appliances, not projects.
What they're known for
Plug-and-plunge cold immersion down to 37°F — no plumbing, no chest-freezer jank, nothing to rig.
Plunge took the thing people used to rig out of chest freezers and turned it into an appliance. The All-In is the current statement: chiller and heat exchanger fully integrated into the tub, no plumbing, cooling to 37°F about a third faster than the first generation. Fill it with a hose, plug it into a wall, get in. That's the entire setup story.
The Compound read: cold water attracts cult behavior, and the equipment shouldn't add to it. What actually decides whether you're still plunging in February is friction — sanitation, temperature drift, maintenance — and Plunge's whole engineering budget goes at exactly that. The $7,990 question was never whether cold water works. It's whether you'll keep getting in.
