Open from 9 a.m. until 2 a.m. seven days a week, the Korean spa's massive 40,000-square-foot facility houses multiple floors, which each feature saunas aimed at providing visitors with relaxation and health benefits. Heated to a pore-opening 200 degrees Celsius from burning oak-tree wood, the dome-shaped hot-steam room—bulhanjeungmok in Korean—features floors made of yellow soil and salt that replicate a 500-year-old therapy designed to treat illness and pain. On the complete opposite side of the temperature spectrum, the ice sauna uses freezer-like frosted walls to cool the air around patrons sitting on log stools or standing on their hands. In between hopping from sauna to sauna, visitors may hang out in one of the lounges, get a haircut, or even grab a warm Korean meal or refreshing dessert.
