What Is Oasis Spa Thonglor Like?
Oasis Spa is a Thai-owned chain that has collected international spa awards for years, and the Thonglor branch (Soi Thonglor 20) is its flagship Bangkok location. Unlike a hotel spa squeezed into a tower, this is a standalone garden compound — you step off the busy soi into lily ponds, Lanna-style pavilions, and birdsong. The 14 treatment rooms are private, air-conditioned, and come with their own showers. Therapists are formally trained, and the signature oils and herbal compresses are made in-house.
Which Treatment Should You Pick?
First-timers can’t go wrong with the 2-hour Thai Body Massage (฿1,750) — the classic stretch-and-pressure style done properly, in a private room rather than a mat-lined hall. If you want something more indulgent, the Ayurvedic Body Massage (฿2,250) uses warm herbal oils in long, flowing strokes — deeply relaxing after a long-haul flight. Short on time or budget? The Thai Herbal Steam (฿700) is a great 30-minute add-on or standalone reset, and the Royal Thai Facial (฿1,450) is popular after sunny days exploring temples.
Getting There
Oasis Spa is on Soi Thonglor 20, off Sukhumvit Soi 55. Take the BTS to Thong Lo station, then a 5-minute taxi or motorbike ride up the soi (around ฿40–60). From central Sukhumvit hotels, a Grab takes 10–20 minutes depending on traffic. Thonglor itself is full of cafes and restaurants, so plan a meal around your appointment.
Tips for Your Visit
- Book 1–2 days ahead for evening slots — the 18:00–20:00 window is the busiest.
- Arrive 15 minutes early to enjoy the welcome tea and garden before your treatment.
- Combine the herbal steam with any massage — steaming first loosens muscles so the massage works deeper.
- Heading south after Bangkok? Read our Let’s Relax Spa Patong review for a Phuket option.

Is It Worth It?
Yes — if you want a genuinely relaxing spa experience rather than a cheap street massage. Prices are roughly double what you’d pay at a no-frills massage shop, but the private rooms, garden setting, trained therapists, and in-house products put it in a different league, while still costing a fraction of Bangkok hotel spas (where similar treatments run ฿3,500+). Booking online brings most treatments 10–17% below walk-in rates.

FAQ
Do I need to book Oasis Spa Thonglor in advance?
Walk-ins are accepted when rooms are free, but evening and weekend slots often sell out. Booking online 1–2 days ahead guarantees your time and gets the discounted rate.
What should I wear or bring?
Nothing special — the spa provides robes, disposable underwear, towels, and showers. Arrive in comfortable clothes and leave valuables at your hotel.
Is Oasis Spa suitable for couples?
Yes — couples can book side-by-side treatments in the same time slot. Mention it when booking so the spa assigns a double room where available.
Thai massage or oil massage — which is better for first-timers?
Traditional Thai massage uses stretching and firm pressure with no oil — invigorating but intense. If you prefer gentle and relaxing, choose the Ayurvedic oil massage instead.
