SO/ SPA at SO/ Bangkok

SO/ SPA sits inside the SO/ Bangkok hotel on S Sathon Road in Bang Rak, pairing Thai-influenced massage and bodywork with a modern cosmetology approach to facials and beauty treatments. It's a hotel spa through and through, built for guests staying on-site rather than walk-in day-trippers.

The treatment menu runs across massage, facial and body work, with the spa open daily from 10:00 to 22:00. Beyond the treatment rooms, the wellness offering extends to a rooftop infinity pool with city skyline views, a relaxation lounge, a thermal pool and a fitness center branded SO/ FIT, which includes personalised workout programmes and activities like kickboxing-style training.

Access is restricted to hotel guests, so this isn't a spot to book as a standalone day pass if you're not staying at the hotel. For guests, though, it functions as a full wellness stop covering a massage, a dip in the infinity pool, and a workout in the same visit — useful if you're in Bangkok on business and tight on time, or just want everything under one roof during a holiday stay.

The spa is part of a broader SO/ Bangkok wellness setup that separates pool hours (06:00–22:00) and fitness hours (06:00–22:00, with 24/7 access for in-house guests) from the spa's own 10:00–22:00 window, so plan treatment bookings around that narrower slot. Contact details and reservations go through the hotel's main line or email, as is typical for hotel-based spas rather than independent day-spa operators.
