Some of the nicer bathhouses even have out door hot-tubs. One of my favorite Korean memories is of sitting with Michael Palmer in the outdoor hot-tub at Paradise Spa with thick snow flakes falling on our heads and feet.
For the small price of about four dollars, you can pamper yourself and ease your tensions for a few hours. We all love it, but John David's favorite part is always the movable shower head without any limitations about getting water all over the place.
Oh, and by the way, everyone's naked - men and women in totally separate rooms.
