Ongi Taejeon

A detached private sauna that opened in June 2026. It runs without staff: at your booked time your name appears on a tablet by the door and the lock opens. Inside a single room sit a warm bath and a cold bath side by side. Few private saunas in Korea include a cold bath, and having both in the same space keeps the cycle between heat and cold unbroken. The sauna is Finnish style, so you pour water over heated stones. The shower and washing areas are separated. Sessions run two hours in two formats. The family room admits mixed-gender groups of up to four for 79,000 KRW; the solo room takes up to two people of the same gender for 45,000 KRW. Each room has a hair dryer, with banana milk and water provided free. It is open daily from 09:00 until 01:00 the next morning, so a late visit works. Booking is through Naver. Enter through the back gate of the apartment complex and mention your visit for free parking. There is no subway station; the nearest bus stop is a minute away on foot.
