To give you more of an idea of what the saunas in Korea are like if you've never been, you can check out these videos.
First is a news report from Al-Arabiya TV showing one that has just opened in Virginia! The only difference I noticed were the tables outside the cafe - western style with chairs, as opposed to floor cushions and foot-high tables.
This one is a Korean commercial for a jjimjilbang. Might want to turn the volume down. (This is a typical Korean commercial, by the way!)
