Reported closed (November 2012).  Trio Club X features include an infrared sauna and herbal steam room that can refresh and detox your skin better than regular dry sauna and steam room.  The sauna also has a bar and nightclub zone that is open until 4am on Friday and Saturday nights.  Massage services available.  Discounts for early birds (before 6pm) and students (under 22).  There is parking, otherwise pickup service is available upon request if you commute by bus to Ramkamhaeng.  Due to its location, Trio tends to attract a more local crowd.
