Search first , then ask !
There were several reports and posts on all those saunas in CFS .
But
HERCULES ( This is the correct spelling ) posts , maybe didn't give you an idea how to get there , so check this out .
HERCULES
K Place is not farang / Non-Thai friendly , so forget it !
G.G sauna is too short ( the name ) to search .
It's close to
Samsen Train station , but I guess you can get there by frequent 14 green mini bus from Victory Monument or CWP .
