About
Let's Relax Onsen and Spa Thonglor fills the fifth floor of the Grande Centre Point hotel on Sukhumvit 55. Separate men's and women's onsen zones hold mineral baths, a sauna and a steam room, and bathing is nude. Outside the zones sit a cool-down room, a relaxation room and hot stone rooms, all included in the onsen ticket.
Good to know
- Hot tub on site: adds a warm-water option between the sauna and the cold plunge for a longer cycle.
- Nude sauna: some or all sessions are taken without swimwear.
- Women-only sauna: the venue has a women's side or room, or runs set women-only sessions.
- Pairs the sauna with spa services like massage or a scrub, so a session can sit inside a wider visit.
- Urban venue: it sits inside the city rather than at a coast or lake. A session fits into a day in town.
