How it works

Why alternating beats either one alone

Heat opens your blood vessels; cold closes them. Alternating does that repeatedly in a short window, moving far more blood through the tissue than either temperature alone — and the heat is what makes two minutes at 42°F achievable.

Why people use it

What it actually does

Soreness after hard training

The repeated flush of blood through muscle is the mechanism most people are here for. Book the day after a heavy session.

Cold, made possible

Few people can sit in 42°F water from cold. From a sauna, two minutes is achievable on a first visit.

Alertness that lasts

Cold raises norepinephrine sharply, and the effect outlasts the session by hours. It is why mornings book out first.

Voluntary discomfort

Voluntarily getting into cold water is a small, repeatable act of discomfort tolerance. Members talk about this one more than any physical benefit.

Your first visit

What happens, start to finish

  1. 01 · ON ARRIVALYour suite is readySauna pre-heated, plunge at temperature. We show you the controls and leave you to it.
  2. 02 · ROUND ONEHeat first — 10–15 minLong enough to sweat properly. You want to be genuinely hot before the cold.
  3. 03 · THENPlunge — 1–3 minStraight in and breathe steady. Two minutes is a full effort on a first visit.
  4. 04 · REPEATTwo or three roundsShorter heats after the first. Finish on cold for alertness, on heat if you are heading to bed.
There is no timer and no instructor. Shower in the suite when you are done.

Questions

Before you book

Anything not covered here, call us — +1 213 686 5600.

First time — 30 or 60 minutes?
Thirty gets you two solid rounds and a shower. Sixty if you want three or four without watching the clock, or you are bringing a guest.
How cold is the plunge?
We have two suites — one plunge runs about 48°F, the other about 42°F. Booking puts you in whichever is open; if this is new and you would rather have the warmer one, tell us at check-in and we will move you if it is free. Confirm room policy
Can I bring someone?
Yes, a guest is included at no extra cost. The suite fits two comfortably.
What do I wear?
Swimwear or shorts. Towels and water are provided and the suite has its own shower.
Before or after training?
After, or on a rest day. If you are training for size specifically, leave a few hours between lifting and cold water.
Who should skip it?
If you are pregnant, on blood-pressure medication, or managing a heart condition, ask your doctor first and tell us at check-in.
