Hongdae 24H Bulgama Sauna

Summarised from publicly available information — a 24-hour jjimjilbang on the second basement floor of the 3RU City building at the Donggyo-dong junction, 200 m from Exit 4 of Hongik Univ. Station. Because the station is on the airport railroad, reviews mention people coming in to sleep a few hours before an early flight. Prices from 1 July 2026 are 12,000 won by day and 15,000 won at night on weekdays for adults, 13,000 won by day and 16,000 won at night on Fridays, weekends and holidays, and 10,000 to 11,000 won for children. Beyond the standard twelve hours it is 1,500 won an hour, and the jjimjilbang outfit is 2,000 won extra. Private rooms can be rented: the large Sun and Moon rooms at 40,000 won for four hours, the smaller Spring, Summer, Autumn and Winter rooms at 20,000 won for four hours. Reviews often praise the friendly staff, the roomy lounge and sleeping area and the fair price, but also note that the baths are small and only two in number, and that sleeping is hard when the sleeping room fills up. Enter through the corridor beside the ground-floor supermarket and take the lift to B2. Wi-fi and parking are available and groups are accepted.
