Inside the Korean Jjimjilbang: A Bathhouse Tradition

The jjimjilbang (찜질방) is a Korean public sauna-and-lounge complex where people of all ages relax, socialize, and unwind in shared spaces. The word literally means "heated room" — from jjimjil (a heat or warming application) and bang (room) — and the modern multi-room version gained popularity in South Korea in the 1990s. This is a cultural guide to what a jjimjilbang is, where the tradition comes from, and the small customs that make it distinctly Korean.

A communal "living room"

Jjimjilbang are often described as communal living rooms. Rather than a single sauna, they are sprawling complexes of rooms kept at different temperatures, with floors warmed by the traditional Korean ondol heating system for lounging. Common amenities include kiln and heat rooms, ice rooms, and open areas where visitors nap, read, or chat.

The bathing areas are conventionally separated by gender, a customary practice in Korean bathhouses; young children may intermingle there. Beyond the baths, the shared lounges are mixed-gender spaces where families and friends gather, which is part of why the jjimjilbang functions as a social hub as much as a place to bathe.

A heritage rooted in centuries

Korea's bathing and sauna culture reaches back centuries. The traditional Korean kiln sauna, the hanjeungmak — first called hanjeungso (한증소) — is recorded in the Annals of Sejong (Sejong Sillok), part of the Annals of the Joseon Dynasty, in the 15th century. From 1429, these kiln saunas were recorded as being built with separate facilities for men and women; in the early Joseon period they were state-supported and maintained by Buddhist monks.

Personal cleanliness has long been noted as a Korean custom. During the Goryeo period, a 12th-century Chinese envoy's account recorded Korean habits of frequent bathing and cleanliness. Yet communal full-body bathing as we know it today is a relatively modern development. During the Joseon Dynasty, Confucian norms made bathing a more private practice and public nudity was discouraged, so communal bathing was not customary.

The shift came late. The first Korean public bathhouses appeared in the late 19th century, associated with the opening of treaty ports and the arrival of Japanese residents, and public bathhouse culture became mainstream in Korea in the 1960s. The neighborhood public bathhouse is known as the mogyoktang (목욕탕) — a Sino-Korean term combining mogyok (沐浴, to bathe or ritually wash) and tang (湯, hot water).

The rituals and small icons

A few customs give the Korean bathhouse its character. The communal body scrub is called seshin (세신) or ttaemiri (때밀이) — the latter word also refers to the scrub attendant. It is a long-standing feature of the Korean bathhouse experience and a ritual many visitors associate with the culture.

Closely tied to it is the Italy towel, the coarse exfoliating mitt found across Korean bathhouses. As a piece of product history, it was invented in Busan by Kim Won-jo, CEO of Hanil Textile, in 1967, and earned its curious name because the viscose fabric originally used was imported from Italy.

Then there is the playful side. A common custom is folding the provided towel into the yangmeori (양머리), or "sheep-head," shape worn on the head — an informal cultural icon instantly recognizable to anyone who has spent an afternoon in a jjimjilbang.

What people eat

Food is part of the ritual. Common jjimjilbang fare includes sauna-roasted eggs (gujeun gyeran) and sikhye, a cold, sweet, fermented-rice drink. These are enjoyed as a cultural and culinary custom — a snack to share between sessions in the heat and ice rooms, often while lounging on the warm floors. The pairing of roasted eggs and a chilled cup of sikhye is, for many, the taste that defines a visit.
