Hot Plunge Pool
Ubud, Bali
The largest hot plunge pool in Ubud. Heated to therapeutic warmth, surrounded by tropical greenery — the place where every session at Hesa begins.
Warm water. Real results.
Our hot plunge pool is maintained at 39–41°C — warm enough to genuinely relax muscle tissue and open blood vessels, but not so hot that it becomes difficult to stay in. It's the temperature used in traditional Japanese onsens and Korean jimjilbangs for exactly this reason.
Large enough for multiple guests, filled with clean, multi-filtered water, and set within a lush tropical garden. It's beautiful to sit in — and the results are real.
Heat is the first step.
Muscle relaxation. Heat penetrates muscle tissue, reducing tension and stiffness — especially effective after long walks, exercise, or time spent sitting.
Improved circulation. Warm water causes blood vessels to dilate, increasing blood flow throughout the body and accelerating recovery.
Detoxification. Sweating in warm water helps flush metabolic waste from tissues — a form of passive detox that requires no effort beyond being still.
Mental calm. The combination of warmth, buoyancy, and tropical surroundings produces a measurable reduction in cortisol levels. Most guests feel noticeably quieter after 10 minutes.
Treatment preparation. Heat prepares the body to receive massage and bodywork more deeply — which is why every Hesa treatment begins with pool and steam access.
The recommended sequence
The hot plunge works best as part of a contrast cycle — not as a standalone soak. The sequence most guests settle into:
Start in the steam room (10–15 min) to open pores and warm deeply.
Move to the hot pool (5–10 min) to sustain and deepen the warmth.
Cold plunge (30–90 sec) to shock the system and lock in the benefits.
Return to hot pool. Repeat 2–3 rounds. The contrast is where the real benefit accumulates.
No treatment booked? Standalone facilities access is available for IDR 300,000 +10% VAT for 2 hours.
About the hot plunge
How hot is the water exactly?
We maintain the hot plunge pool at 39–41°C. This is the therapeutic sweet spot — warm enough to relax muscle tissue and dilate blood vessels, but not uncomfortably hot. It's close to the temperature of a traditional Japanese onsen.
How long should I stay in the hot pool?
Most guests stay 5–15 minutes per round. There's no strict rule, but we recommend 5–10 minutes before a cold plunge, and longer relaxation soaks between treatment steps. Listen to your body — if you feel lightheaded, step out and cool down gradually.
Is the water clean? How often is it changed?
All water at Hesa is multi-filtered to the highest standards. The filtration system runs continuously. We take hygiene seriously — it's one of the most common things guests mention in reviews.
Can I use the hot pool without booking a treatment?
Yes. Standalone facilities access (hot pool, cold pool, steam room) is available for IDR 300,000 +10% VAT for 2 full hours — plenty of time for multiple rounds of contrast therapy (hot plunge → cold plunge → steam → repeat). Last booking is 6:30 PM. Book here →
Is the hot pool included in treatments?
Yes — 30 minutes of facilities access (hot pool, cold pool, and steam room) is included with every treatment booking, for light preparation or a short post-treatment session. For the full contrast therapy experience with multiple rounds (hot plunge → cold plunge → steam → repeat), book standalone facilities access (2 hours).
Are the pools suitable for people with health conditions?
Hot water therapy is generally safe for healthy adults. If you have cardiovascular conditions, high blood pressure, are pregnant, or have any medical concerns, please consult your doctor before using hot plunge or contrast therapy. Our team is happy to answer specific questions — contact us via WhatsApp before booking.
