Oasis Spa (Bangkok, Sukhumvit 31)
64 Sukhumvit 31 Yaek 4, Khlong Tan Nuea, Watthana, Bangkok 10110
Oasis Spa Sukhumvit 31 is built for guests who want a full resort spa feel inside central Bangkok. The lush garden compound creates genuine separation from the city, the treatment room count is generous for a day spa, and the reservation line runs daily from 08:30 to 21:30. The free BTS transfer removes the last logistical friction for visitors staying along the Sukhumvit corridor.
You walk through a garden pathway bordered by tropical planting and arrive at a compound that reads nothing like the Sukhumvit streetscape you just left. Oasis Spa at Sukhumvit 31 Yaek 4 is the flagship Bangkok branch of the Oasis Spa network, and the property earns its 'secret garden' description in physical terms: twelve treatment rooms are distributed across the grounds, each equipped with outdoor showers, soaking baths, or massage beds designed for two guests.
Relaxation platforms overlooking lotus ponds and a waterfall feature give the property a resort character rare for a day spa operating at this address. The branch sits within walking distance of BTS Phrom Phong, Terminal 21, and The EmQuartier, but the venue provides complimentary transfers from Phrom Phong station to smooth the arrival for guests unfamiliar with the soi layout.
Oasis Spa as a brand positions itself around what it calls a fusion of Lanna heritage techniques and contemporary wellness methods, drawing on northern Thai herbal and bodywork traditions. The Bangkok network includes three separate city properties: this Sukhumvit 31 address, GAAYA by Oasis Spa on Sukhumvit 39, and Urban Oasis Spa in Ekkamai, each carrying the same reservation line (+66 2 262 2122) and the same daily operating window of 10:00 to midnight.
For the Sukhumvit 31 branch specifically, the design emphasis falls on the outdoor and garden-integrated elements rather than a traditional Thai shophouse setting. The treatment room pairing options, the two-person massage beds, and the soaking bath configuration make it a clear choice for couples or guests looking to extend a single visit into an extended stay rather than a single-treatment drop-in. Reservations are recommended, with the booking line open daily from 08:30 to 21:30.
