A Korean bath is built around one fact: the wet area is divided by sex, and everyone in it is naked. Most questions, from "can my son come in with me" to "where do I go if I am trans", follow from that. Where a facility has a clothed jjimjilbang (찜질방) hall, that is where a split group meets again.
We give the law where there is law and the facility rule where one is in writing, and we say plainly where we found nothing.
Children: the age rule and what facilities add
The rule is in the enforcement rules of the 공중위생관리법 (Public Health Control Act). A bathhouse may not let a child aged 4 (48 months, 만 4세) or older into the bathing or changing rooms of the opposite sex. A four-year-old boy cannot enter the women's bath with his mother, and a four-year-old girl cannot enter the men's bath with her father. The limit was lowered from age 5 (만 5세) and has applied since 22 June 2022. The rule binds the operator: penalties run from a warning to a suspension and, after a fourth violation, closure.
Facilities may add their own rules. Sparex in Seoul bars boys taller than 105 cm from the women's bath. Spa Land in Busan does not admit children under 7, and children aged 7–13 must come with an adult of the same sex.
| Facility | Child rules and prices | Seen |
|---|---|---|
| Sparex Dongdaemun | Under 24 months free; 24 months to 7 years ₩7,000 day, ₩8,000 night; age 8 and over pays the adult rate | 2026 |
| Hurshimchung (허심청), Busan | Preschool ₩7,000; elementary school ₩11,000 weekday, ₩12,000 weekend | 2026 |
| Spa Land Centum City, Busan | Under 7 not admitted; ages 7–13 with a same-sex adult; elementary school ₩20,000 | 2026 |
| Aquafield Hanam | Under 36 months free; child (to the end of elementary school) ₩21,000; adult from middle school | 2026 |
| Paradise City Cimer, Incheon | Under 7 not admitted; child ₩30,000 jjimjil spa, ₩50,000–60,000 aqua spa | 2026 |
Heat is the other limit. The notice the law requires at every sweat room lists children under 5 among those who should take care. Keep hot-room time short and skip the kilns; see the health guide.
Minors also have a night rule. At 24-hour facilities, anyone under 19 may not stay between 22:00 and 05:00 unless they are with a parent or guardian, carry the guardian's written consent, or are with a supervising adult or teacher.
Splitting up and meeting again
A mixed group separates at the doors marked 남 (men) and 여 (women). Each person gets a wristband that is both locker key and tab; see the first-visit guide. You meet again in the clothed hall, where everyone wears the issued jjimjilbok (찜질복); the law requires it in mixed-sex sweat rooms. Phones are allowed in the lounge but not in the locker and bath areas, so agree on a time and a meeting point before you split. A plain mogyoktang (목욕탕) usually has no shared hall; meet outside.
If one parent is alone with an opposite-sex child over the age limit, two kinds of place can help.
- Private family baths (가족탕, gajoktang) are found in hot-spring towns. Halmae-tang (할매탕) in Haeundae has one on its second floor, by reservation (₩80,000, October 2023). Cheoksan Oncheon Resort (척산온천휴양촌) in Sokcho rents family hot-spring rooms for three hours, at ₩50,000 for two people or ₩70,000 for four (April 2025). Bugok (부곡) in Gyeongnam counted 1,355 family-bath rooms in February 2025; see the regions guide.
- Swimwear spas are mixed, clothed and more expensive. Club D Oasis in Busan has an outdoor seawater hot spring used in swimwear (adult ₩30,000, child ₩24,000, 2026). Termeden in Icheon requires a swimsuit and swim cap throughout (adult ₩54,000, child ₩44,000, 2026 peak season).
It's my first time here.
Women: women-only venues, sleep rooms and safety
Seoul has several women-only facilities. Golden Sauna Myeongdong (황금사우나 명동) is a 24-hour kiln sauna with two sleep rooms (₩20,000, February 2026). Hana Mud Hanjeungmak (하나머드 한증막) in Euljiro sells scrub courses, from ₩72,000 online (October 2026). Spa Lei (스파레이) in Sinsa has seawater and open-air baths; a 2026 guide could not confirm its hours. A 2026 travel blog reports women-only sleeping rooms (여성전용수면실) at most major bathhouses; Hongdae 24-hour Bulgama Sauna has one.
The law helps. Staff in the bathing, changing and sweat rooms must be the same sex as the guests there, and no opposite-sex scrub attendant may work in them. CCTV is allowed only outside those rooms. Filming in a changing room is a sex crime. In 2023, a man who filmed in a women's changing room at a Daejeon bathhouse was arrested on the spot.
The weak point is the shared sleeping hall at night. Two incidents have been reported: a 2025 legal case of a drunk man touching a sleeping woman, and a 2022 traveler account of unwanted sexual behavior in a hotel sauna's sleeping area. Two reports are not a pattern. Still, sleep in a women-only room or venue, lock valuables away, and tell staff about anyone drunk; the law bars people too drunk to use the facility. The overnight guide has more.
Accessibility: what we know
Not much. A 2026 guide says accessibility details are largely undocumented and must be checked with each venue; we found nothing better. Many of the Seoul places we list are underground or on upper floors. Sparex Dongdaemun is on basement level 3, reached by elevator, and Sparex Dongmyo is on the 12th and 13th floors. Falls are the main injury: of 1,790 bathhouse injuries reported from 2021 to June 2025, 89.3% were slips and falls. In a survey of 16 Seoul bathhouses, none had anti-slip mats around the scales, sinks and water dispensers. Aquafield gives a 20% discount to registered disabled visitors and one companion; we found no other concession. We will add access notes to the directory as we measure them.
Modesty, religion and privacy
We found no Korean guidance for Muslim or other religious visitors, and no facility that advertises a prayer space. The bath hall is nude, and swimwear is not worn in the pools unless the facility says so. You may hold a small towel in front of you while walking, but it stays out of the water.
If nudity is not acceptable to you, the options are a private family bath in a hot-spring town, a swimwear spa, or a hotel room with its own bath. A women-only venue removes men, not nudity. Hotel saunas are not always open to visitors: Lotte Hotel Seoul and Lotte Hotel Busan admit only guests and members. Private Finnish-style saunas are a new option. 솔로사우나 레포 (Solo Sauna Repo) has women-only, men-only and family rooms, and a private sauna in Sinsa-dong (시수하우스) sells 90-minute solo sessions; neither published prices in the articles we found.
LGBTQ+ and non-binary visitors
The law requires changing and bathing rooms to be run separately for men and women, and buildings have separate men's and women's sections. Nothing in the rules we retrieved addresses the gender identity of adults, and we found no published national or industry policy. The only 2025–2026 coverage we found concerns Korean-style spas in the United States, and it does not discuss Korea. Some facilities ask for a passport or ID, and one guide says entry can be refused without it, even for adults. We found no source on whether staff check sex against the ID.
In practice, the decision rests with the staff at the counter. The alternatives are those in the previous section: a private family bath, a swimwear spa, a family room at a private sauna, or a hotel bath. We found no rule that affects same-sex couples; the baths are single-sex by design, and the hall is a public lounge.
Periods, scars, devices and older travelers
Menstruation. We found no published rule and no Korean source on custom, so we state none. Recirculated bath water must pass a chlorine, ozone or UV sterilizer. The sauna rooms and the clothed hall do not require entering the pools.
Scars and medical devices. The law requires a bathhouse to refuse people with an infectious disease and people too drunk to use it; scars are not on that list. Written cover-up rules exist for tattoos, for example a 15 cm limit at some hotel pools and saunas (see the tattoos guide); we found none for scars. With a heart condition or device, the heat is the issue. The required notice warns people with severe heart disease, and specialists quoted in 2026 warn that rapid hot-to-cold changes can cause arrhythmia in heart patients. Ask your doctor, and skip the cold pool.
Older travelers. One Busan bath owner's routine is 5–15 minutes in the sauna, one minute in the cold tub and about ten minutes of rest, three times. People aged 60 and over accounted for 62.9% of reported bathhouse injuries, mostly slips and falls, so dry off before you walk and bring your own slippers. After two men in their 60s and 70s died in separate bathhouses in May 2026, the fire authorities advised warming up gradually, soaking no more than 10–15 minutes and resting afterward. Clinicians add: older people should use lukewarm water, and people with high blood pressure or angina should skip hot–cold alternation. We found no published senior discounts.
