I get my bikram hot yoga done at Raffles City Shopping Centre #02-14.
Its called "Bikram Yoga City Hall". Apparently the 1st authroised Bikram studio to open in Singapore since 2006.
The heat is great and constant, absolutely fanstic high quality service and the location is really good (just above city hall mrt).
The best part is that the mats are provided so you dont have to bring yours, and the mats are literally sent to laundry after each person has used it.
so go try it.
