KLAI Thai Spa
101, 103-105 Thanon Phat Sai, Khwaeng Samphanthawong, Khet Samphanthawong, Bangkok 10100
The herbal inhaler workshop is the reason to come. You blend your own dry herb formula, and the finished inhaler goes home with you. The massage menu delivers proper Thai technique rooted in Rishi Dat Ton stretching, sen line work, and foot-stepping adapted from Chela Sak. Book the 90-minute Yeud Klai for deep stretches without oil.
You step off Thanon Phat Sai into a renovated Sampanthawong shophouse where the air carries a custom herbal scent (indigo and Thai herb notes, blended by Thom-Sirinart Lertthap specifically for this space). Ambient sounds loop in the background. Bird songs, waterfalls.
The massage menu is built on three techniques rooted in traditional Thai bodywork: Yeud Klai (stretch massage incorporating Rishi Dat Ton principles), Nuad Klai (pressure-point work following the ten primary energy lines), and Yiab Klai (foot massage adapted from Chela Sak stepping techniques).
Beyond the treatment rooms, the workshop zone lets you blend a personalized herbal inhaler from Thai herb ingredients. You pick the formula, the staff guide the assembly, and the finished inhaler leaves with you. KLAI Café sits adjacent, pouring non-alcoholic drinks designed around natural elements by an award-winning Thai bartender.
Sessions start at 600 baht for 60 minutes and run up to 2,550 baht for 120-minute treatments that layer in herbal compress or hot oil work with custom balm formulas. Book ahead by phone or LINE; walk-ins depend on therapist availability, especially on weekends and evenings when the treatment rooms fill. Hours run 11AM to 9PM daily, closing earlier than the 11PM windows you find at many larger Bangkok spas, so plan your post-dinner timing accordingly. The space is part of the Onsen Retreat and Spa Group portfolio, designed by 67 Studio to reinterpret traditional Thai spa heritage through contemporary architecture and deliberate sensory layering (custom scent, natural sound recordings of bird songs and flowing water). Expect proper technique grounded in Rishi Dat Ton and sen line work, with an atmosphere calibrated for calm and intentionality.
The space welcomes kids (verified child-friendly), accepts all payment methods including cards and NFC, and the herbal inhaler workshop makes an especially good pairing with a massage session. You leave with more than just relaxed shoulders.
