Ibex Basin builds temperature-precise plunge studios where every session is dialed to 38°F, tracked to the second, and choreographed into a recovery ritual you'll never skip.
Our chillers stabilize each basin within 0.3°F so the shock is deliberate, never chaotic. No warm pockets, no guesswork — just the exact cold your protocol calls for.
A guided breath-and-immersion arc projected on the basin wall, escalating from 60 seconds to 4 minutes over your first six weeks. Progress is earned, not improvised.
HRV, skin temp, and recovery score sync to your Ibex profile the moment you rise. See the adaptation curve most plungers never get to measure.
Studios run on eight-minute slots from 5am. Reserve, arrive, plunge, and be at your desk by 6 — no lobbies, no towels-at-the-door chaos.
Every basin pairs with an infrared alcove and cedar bench so the reheat is as ritualized as the cold. Warm earth, cold water, one continuous rite.
From high desert to coastal fog, each location tunes water chemistry to local conditions. Your membership plunges the same everywhere you travel.
“I used to wrestle a wheelie-bin of ice in my garage at 5am. Ibex Basin turned my most dreaded ritual into the calmest eight minutes of my day. The HRV data alone rebuilt my sleep.”
“Our whole product team plunges before standup now. The Ascent protocol gave people who'd never touch cold water a way in — and the recovery scores are genuinely absurd.”
“As a physiotherapist I'm ruthless about protocols. Ibex holds temperature better than the clinical tanks I trained on, and the session logs let me prescribe cold like I prescribe reps.”
Start free-ish. Upgrade when it hurts.
Four guided plunges a month to build the habit without the shock to your calendar.
Unlimited cold for the daily practitioner who treats recovery as training.
