Ice bath & cold plunge in Saigon

Quick answer: at Ōmni Space in Thao Dien you can take a private ice bath in water kept at 11–15°C. A 30-minute session costs 450,000 VND, +200,000 VND with any float, or 900,000 VND together with the infrared sauna for hot–cold contrast. The room is private for you and up to 3 friends. Open daily 9:00–21:00; walk-ins welcome until 18:00.

What to expect

You change in a private room with its own shower, then step into a cold plunge tub kept at 11–15°C. That is cold enough to feel the rush, but gentler than the near-freezing tubs some gyms use, so it suits first-timers as well as regulars. You decide how long you stay: most people do a few short rounds within the 30-minute session. The room fits up to 4 people, so you can come with a partner or friends.

How long should you stay in an ice bath?

• First time: 1–2 minutes per round, 2–3 rounds.
• Regulars: build up slowly to 3–5 minutes per round.
• Over a week: more is not always better. For reference, the winter swimmers in a 2021 study averaged about 11 minutes of cold water and 57 minutes of sauna per week (Søberg et al., Cell Reports Medicine, 2021).
• Always get out straight away if you feel numb, dizzy or unwell.

Why people take an ice bath

• A sharp, clear-headed reset. In one well-known study, immersion in 14°C water raised noradrenaline by about 530% and dopamine by about 250% (Šrámek et al., European Journal of Applied Physiology, 2000). Our 11–15°C water sits in that same range.
• Recovery after training. Reviews of sports research have found that cold water immersion after exercise can reduce muscle soreness.
• Building calm under stress. Slow breathing in cold water is a simple way to practise staying relaxed when the body is uncomfortable.

Contrast therapy: sauna + ice bath

Alternating heat and cold is one of the most popular recovery rituals in the world, from Finnish saunas to modern recovery studios. At Ōmni Space the infrared sauna and the cold plunge are side by side, so a contrast session is easy:

Step	Time	Tip
Infrared sauna (45–55°C)	10–15 min	Warm up until you sweat lightly
Cold plunge (11–15°C)	1–3 min	Breathe out long and slow
Rest	2–5 min	Sit down and drink water
Repeat	2–3 rounds	Finish cold to feel alert, or warm to relax

Sauna and cold plunge together cost 900,000 VND.

The full reset: sauna, ice bath, then float

For the deepest reset in Saigon, finish with a float. Warm up in the sauna, wake up in the ice bath, then let 500 kg of Epsom salt carry you in silence for 90 minutes. A 90-minute float with both the sauna and the cold plunge costs 2,400,000 VND. New to floating? Read what float therapy is.

Why Ōmni Space for an ice bath

• Private, not a crowded gym: the room is yours, alone or with up to 3 friends.
• Beginner-friendly cold: 11–15°C instead of near-freezing water.
• Infrared sauna next door for proper hot–cold contrast.
• Add a float: Ōmni Space is Saigon’s float therapy centre, from the team behind Vietnam’s first float centre (Hanoi, 2017).
• Easy to reach in Thao Dien: 16C Quốc Hương, open every day 9:00–21:00.

How to plunge safely

• Get out straight away if you feel numb, dizzy or unwell.
• Warm up gradually afterwards with a warm shower or the sauna.
• Do not cold plunge if you have a heart condition, high blood pressure, Raynaud’s or cold urticaria, or if you are pregnant, unless your doctor agrees.
