What a Korean spa is

A Korean spa (jjimjilbang) is a large bathhouse with gender-separated wet areas (hot and cold pools, showers, steam and dry saunas) and a shared, clothed area of heated rooms lined with clay, salt, jade or charcoal. Entry is usually a day pass, and many have a restaurant, sleeping areas and body scrubs.
