A jjimjilbang (Korean pronunciation: [t͈ɕimdʑilbaŋ]; Hangul: 찜질방; Hanja: 찜질房; MR: tchimjilbang) is a large, gender-segregated public bathhouse in Korea, furnished with hot tubs, showers, Korean traditional kiln saunas and massage tables. Jjimjil is derived from the words meaning heating. In other areas of the building or on other floors there are unisex areas, usually with a snack bar, ondol-heated floor for lounging and sleeping, wide-screen TVs, exercise rooms, ice rooms, heated salt rooms, PC bang, noraebang, and sleeping quarters with bunk beds or sleeping mats. Many of the sleeping rooms have themes or elements to them. Usually jjimjilbangs will have various rooms with temperatures to suit guests' preferred relaxing temperatures. The walls are decorated with woods, minerals, crystals, stones, and metals to make the ambient mood and smell more natural. The elements used have traditional Korean medicinal purposes in the rooms.
Most jjimjilbangs are open 24 hours and are a popular weekend getaway for Korean families. During the week, many hardworking Korean men, whose families live out of the city for cost savings, stay in jjimjilbangs overnight after working or drinking with co-workers late into the night. The cost is around 8,000-12,000 won to enter, and one can sleep overnight and enjoy the bathhouse and sauna.
Jjimjilbangs usually operate 24 hours a day. In the entrance, there are the doors labelled “men” or “women” and shoes are to be stored using a given key. Once inside, the shoe locker key is exchanged with another locker key to store clothes and belongings. Afterwards bathers walk into the gender-segregated bathhouse area (children of both genders below seven years of age are free to intermingle) and take a shower. Then, one should wear the jjimjilbang clothes (usually a T-shirt and shorts, color-coordinated according to gender), which are received with the locker key.
