A jimjilbang is a large Korean bathhouse with hot pools, saunas, and heated resting rooms. Expect to get fully naked in the gender-separated bathing areas (this is normal and everyone ignores each other). After scrubbing and soaking, you wear the provided shorts and t-shirt in the mixed-gender common areas where people nap, watch TV, eat, or sweat in various themed dry saunas. It’s a genuinely local experience—families, couples, and tired office workers all go. The whole place usually stays open 24 hours.
Best time is autumn or winter; the contrast of cold outside air and hot baths feels perfect. Summer works too but the heat can get overwhelming. Expect to pay around $15–30 for basic entry and access to everything for several hours; food, massages, or overnight sleeping bumps it up a bit. Go in the evening and stay through the night if you want the full cultural hit.
Pick the plain hot pools and the hottest traditional saunas; skip the gimmicky ice rooms or overpriced “premium” add-ons. Bring a change of underwear, your own toiletries if you’re picky, and don’t overthink the nudity—everyone’s just there to relax. It’s cheap, interesting, and one of the few places where you see everyday Seoul life without the tourist filter.
