What Is a Cold Plunge?
A cold plunge is a few minutes of sitting in cold water with your head above the surface, in a tub built and chilled to hold a steady temperature. At sēk the water is held at 42 degrees, the room is yours alone, and nothing about it is a test you have to pass.
What the Cold Feels Like
The first 30 seconds
Your breath catches and speeds up. That is the cold doing what cold does, not a sign that something is wrong. Breathe out slowly, longer than you breathe in, and it passes.
The settle
Somewhere in the first minute or two the water stops feeling like an emergency. Your breathing evens out, your shoulders come down, and the cold turns into something you are simply sitting in.
The clear stretch
From here most clients stay 2 to 6 minutes. Still, alert, unusually present. When you have had enough, you get out. That is the whole rule.
The first time, a specialist walks you through all three.

Your Session
Before
Come in a swimsuit if you would like a specialist to coach you through it, and skip lotions, oils and cosmetics beforehand. The first time, a sēk specialist walks you into your private room, shows you the tub, the timer and the call button, explains the pace, and steps out. The room is yours from there.
During
Get in at your own speed and breathe out slowly. First-timers often get in and out in 30 to 60 second stretches until the water stops feeling like a shock. The room is yours for 15 minutes and most clients plunge for 2 to 6 of them. There is no target to hit and the call button is within reach the whole time.
After
A warmed towel is waiting for you. Dress warm and let your body come back up to temperature on its own. A Vitamin C shower is available to every client if you want one, though we suggest holding off right after a session so the cold keeps working.
The Water
Clean water is not an afterthought here.
Our cold plunge is a Plunge All-In, built for daily studio use. Its onboard system circulates, filters and ozone-sanitizes the entire volume of water every 15 minutes. The chiller holds 42 degrees without drifting. And because every session is private, it is one guest at a time, in a room with the door closed.

What sēkers Say
“The cold plunge elevates my mood and I feel rejuvenated after every dip into the icy water.”

Cold Plunge FAQs
Before You Book
Talk with a healthcare professional first if you are pregnant or have a heart condition, high blood pressure, Raynaud's syndrome or a pacemaker. Do not plunge after drinking alcohol or when you are unwell.
You are never on a timer you did not set. Every room has a call button, the door is yours, and if you want out of the water, get out of the water.
