Which luxury spas in Bangkok are worth booking?
7. Away Spa at W Bangkok
Away Spa starts with a detox drink and a conversation about your preferences, then offers face and body massage plus a sauna, steam room and jacuzzi. Prices are on request.
Ranked by tier because rates are not published.
6. Spa InterContinental

Placed by hotel standing; ask the spa for a quote.
5. The Okura Prestige Spa
The Okura offers Japanese-inspired rituals, including a Sakura blossom oil massage and body scrub and a green tea scrub. Rates come on request.
We placed it by hotel category since prices are not public.
4. Chi, The Spa at Shangri-La
Chi draws on Himalayan-inspired themes and mixes Thai and Asian techniques such as pressure points, clay, oils and herbs. Ask the spa for rates.
Rank based on hotel tier, as no price list was available.
3. The Spa at The Peninsula
The Peninsula’s spa blends Thai, European and Ayurvedic ideas, with a large menu of face, body and men’s treatments and bespoke programmes. We found no published prices.
No prices are published, so this position is our judgement.
2. Banyan Tree Spa
The Banyan Tree Spa uses therapists trained at the company’s own academy and an Asian-themed set of treatment suites. Booking sites list a 60-minute treatment from THB 4,200, and one guide reports a 120-minute Rainforest Experience programme near THB 9,000.
Third-party listing prices set this position, and they are approximate.
1. The Oriental Spa, Mandarin Oriental
The Oriental Spa has separate rooms for each treatment type, hydrotherapy options and yoga and meditation spaces. An older official brochure listed Oriental Harmony, a two-hour four-hand treatment, at THB 15,400, with Oriental Bamboo at THB 9,000 and the Lanna Ceremony at THB 8,250. The brochure is no longer online, and 2026 guides quote lower and conflicting figures, so confirm before booking.
Its place rests on the highest official price we found, which is an older one.
