TWO ICE BATHS IN BERLIN: 0–2 °C AND 6–8 °C

0–2 °C and 6–8 °C: our tubs, measured before every slot

We keep our ice baths at 0–2 °C and 6–8 °C all year and measure the temperature before every slot — you can read it on the display at the tub. For comparison: cold plunges are often run at around 8–12 °C. The colder the water, the shorter the stimulus: 1 to 3 minutes are enough at 0–2 °C, while you can stay longer in the 6–8 °C tub.

For you that means reliably the same cold on a Tuesday morning as on a Sunday evening — not depending on the weather, the crowd or the time of day.

The water is filtered continuously (pre-filter, 30-micron filter, UV-C) and checked regularly. Showering before the ice bath is mandatory.

Benefits of ice bathing

• Sharper head: the cold forces slow, deliberate breathing, and most people leave calmer and more focused than they arrived.
• Recovery after training: a short plunge is a popular way to take the edge off heavy legs and post-workout soreness.
• Stress practice: staying with a strong but safe stimulus for two minutes is trainable — and it transfers to everyday pressure.
• Sleep and mood: many guests report deeper sleep on ice bath days, especially combined with the sauna and rest phase.
• Contrast effect: hot to cold and back again feels far better than either on its own, which is why the Free Flow pairs them.

Safety first

The cold is powerful, so we keep it boring: you are never alone in the Fire & Ice zone, the temperature is displayed, and a staff member is within earshot the whole time.

• Never hold your breath and never put your head under water.
• No hyperventilation drills before entering, no alcohol, no plunging on an empty or very full stomach.
• Get out if you feel dizzy, numb in a painful way, or if shivering turns into shaking — the session is not a contest.
• Rewarm passively: dry off, move gently, sauna or red light. No hot shower straight after.
• Talk to us first if you are pregnant or have cardiovascular conditions, high blood pressure, epilepsy, Raynaud's or recent injuries; when in doubt, ask your doctor.

Ice bath in Friedrichshain

Boxhagener Straße 96, 10245 Berlin. We sit inside a listed 1893 horse stable between Boxhagener Platz and Ostkreuz — a five-minute walk from the RAW site and the Warschauer Straße bars, which makes an early morning plunge or a post-work round easy to fit in.

A few minutes' walk from Ostkreuz, Boxhagener Platz and Warschauer Straße — easy by S-Bahn, U-Bahn, tram or bike. Bring a towel and, if you like warm feet, a pair of sliders — swimwear is optional.
