This 24-hour multilevel spa takes the Korean spa tradition to extravagant heights. Separate men's and women's floors (patrons bathe in the buff) feature hot and cold tubs plus dry and steam saunas, while everyone gathers in the communal "Jimjilbang" space for specialty mineral saunas. You'll shed layers with the traditional Korean body buff.
