The 12th Floor of Grand Fortune Hotel Bangkok is home to an Onsen spa which is available for use to all guests including those with a Wellness Membership. 

Bathing in an Onsen is an important tradition for the Japanese and has been since so ancient times. The original Onsens were heated by pressurized volcanic activity below the earth’s surface which caused minerals to seep into the water, providing health benefits for the bathers.

Open daily 6.00 – 20.00 hrs.
