Once Upon A Thai Wellness & Spa
Timeless relaxation in the heart of Bangkok
Bangkok can be loud, fast and overwhelming — which makes quiet sanctuaries like Once Upon A Thai Wellness & Spa all the more valuable.
Tucked away in the Ratchadamri area, just a short stroll from Lumpini Park, this boutique spa blends traditional Thai wellness with a refined, contemporary touch.
From the moment you step inside, your heartbeat slows. The scent of wood and herbs lingers in the air, lights are dim, and soft music fills the space — more luxury resort than city spa. You’re greeted with a herbal tea before being led to one of the private treatment suites, each featuring its own onsen bath, aroma therapy room, or herbal sauna.
The signature experience — a Therapeutic Aroma Massage & Onsen Soak — combines traditional Thai pressure techniques with modern relaxation rituals. Therapists are highly skilled, adjusting intensity and rhythm intuitively. It’s not a one-size-fits-all treatment; it’s tailored to how your body feels that day.
Those looking for the full experience should try a longer treatment combo with exfoliation, oil massage and onsen. You’ll leave with softer skin, looser shoulders and a clear mind. Small details — like a warm herbal compress or a scoop of coconut ice cream after the session — make it feel even more special.
