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!)
This is another promo for a jjimjilbang in the U.S., but I'm not sure where. This one looks great, but the difference this time is the handrails to get into the tubs. Here, if you slip, it's your own fault!
Yeah, I kept looking, but most other videos are crap. There you go.
