Imagine standing in a locker room at a korean sauna(Jjimjilbang) in Seoul. Around you, locals are chatting comfortably, completely naked. In your hand, you hold a strange orange uniform. You have a split-second decision to make: Do I put this on now? Or do I walk through that door naked?
If you make the wrong choice, and you might face the most embarrassing moment of your trip.
Welcome to the Korean sauna and spa, “Jjimjilbang (찜질방)”, Korea’s unique 24-hour spa culture. It is a place of relaxation, cheap accommodation, and intense cultural shock. For many foreign travelers, the Jjimjilbang is a bucket-list item, but it comes with a massive hurdle: The Fear of Nudity.
“Do I really have to be naked?” “What do I wear under the uniform?” “How do I not look like a stupid tourist?”
Don’t worry. I have been there, and I am here to guide you. As your local expert from Tripplankorea, I will walk you through every single step—from the shoe locker to the sleeping mat—so you can strut into the sauna like a local.
What Exactly is a korean sauna(Jjimjilbang)?
Before we undress (figuratively), let’s clear up the biggest confusion. A korean sauna(Jjimjilbang) is not just one room. It is a massive complex divided into two distinct worlds with opposite rules:
- The Mokyeoktang (Bathhouse / Sauna):
- Rule: 100% Naked.
- Who: Gender Segregated (Men only / Women only).
- Activity: Washing, soaking in hot tubs, scrubbing.
- The Jjimjilbang (Common Area):
- Rule: 100% Clothed (You must wear the provided uniform).
- Who: Mixed Gender (Everyone together).
- Activity: Eating, sweating in dry kilns, watching TV, sleeping.
Understanding this separation is the key to your survival. Now, let’s start the simulation.
Phase 1: Arrival and The “Magic Key” System
When you enter a korean sauna(Jjimjilbang), you aren’t just paying for entry; you are entering a cashless society.
1. The Entrance Fee
At the front desk, you will pay the entrance fee. Prices usually range from 10,000 KRW to 15,000 KRW ($7~$12 USD).
- Daytime (jo-gan): Cheaper (usually before 8 PM).
- Nighttime (ya-gan): Slightly more expensive if you plan to stay overnight.
2. The Key and The Uniform
Once you pay, the staff will give you two items:
- A Key (Bracelet): This is your identity. It usually opens both your shoe locker and your clothes locker. Crucially, in some korean saunas, it acts as your credit card. Inside, if you want to buy eggs or a massage, you tap this key. You settle the final bill at the counter when you leave. Do not lose this key. But there are still some korean saunas that you have to bring your card so we recommend to bring one.
- The Uniform (Jjimjil-bok): A cotton T-shirt and shorts. Do not put these on yet! hold them.
3. The Shoe Exchange
This is the first test. You must take off your shoes at the entrance and put them in a small shoe locker designated by the number on your key (or you get the key from the shoe locker). You are now officially inside the barefoot zone.
Phase 2: The Locker Room (The Point of No Return)
You will now separate from your friends of the opposite gender. Men go to the “Nam-tang” (Blue sign), women go to the “Yeo-tang” (Red sign).
Find the locker that matches your key number. This is your base camp. Open it, and take a deep breath.
The Strip Down
This is the part everyone dreads. You must take off everything.
- No swimsuits.
- No underwear.
- No towels wrapped around your waist (while walking is okay, but not in the water).
💡 Pro Tip: If you are shy, you can use a small “modesty towel” to cover your front while walking from your locker to the bath area. However, once you enter the water, the towel must stay out of the tub (put it on your head or the side).
What to bring into the bath:
- Your locker key (wear it on your wrist or ankle).
- Toiletries (shampoo, soap).
- A small towel / exfoliating towel.
What to leave in the locker:
- Your phone (Cameras are strictly illegal in the locker/bath area).
- The uniform (Leave it here for Phase 4).
Phase 3: The Sauna / Mokyeoktang (The Naked Zone)
You push open the glass doors and enter the humid, misty bathhouse. It smells of soap and herbal water. Do not just jump into the nearest hot tub. There is a strict protocol.
Rule #1: The Pre-Wash Ritual
In Korea, the bath water is shared by everyone. Therefore, you must be “squeaky clean” before you enter.
- Find an empty shower station (usually a handheld showerhead with a plastic stool).
- Sit down. (Standing showers exist, but sitting is the traditional way to avoid splashing your neighbor).
- Wash your body and hair thoroughly with soap.
- Rinse well.
If you skip this step, you will receive dirty looks or even a scolding from the “Bathhouse Ajumma/Ajeossi” (the guardians of the sauna).
Rule #2: Enjoying the Tubs
Now that you are clean, try the tubs. They range in temperature:
- On-tang (Warm Bath): 38°C – 40°C. Good for starting.
- Yeol-tang (Hot Bath): 42°C – 45°C. Very hot. Enter slowly.
- Naeng-tang (Cold Bath): 18°C – 20°C. Shockingly cold, but amazing for circulation after a hot soak.
Rule #3: The “Seshin” (Korean Scrub) Experience
In a corner, you will see people lying on plastic tables being scrubbed vigorously by a staff member wearing underwear. This is Seshin.
- What is it? A professional exfoliation that removes layers of dead skin you didn’t know you had.
- Cost: Usually 20,000 ~ 30,000 KRW (Cash implies, or key tap).
- Verdict: It hurts a little, but your skin will feel as soft as a newborn baby’s afterward. Highly recommended!
Phase 4: The Transition (The “Underwear” Dilemma)
You have soaked, you have scrubbed, and you are feeling relaxed. Now it’s time to meet your friends in the common area.
- Go back to the locker room.
- Dry yourself completely with a towel. Do not drip water on the floor.
- Put on the Uniform (T-shirt and Shorts).
Here comes the most frequently asked question that no guidebook answers clearly:
👙 The Big Question: “Do I wear underwear under the uniform?”
You are standing there, holding the loose cotton shorts. You wonder, Is everyone else going commando?
The Short Answer: It is up to you, but most Koreans do NOT wear underwear.
The Explanation:
- Sweat Factor: The main purpose of the common area is to enter high-temperature kilns (50°C ~ 90°C). You will sweat profusely. If you wear cotton underwear and a bra, they will get soaked, sticky, and uncomfortable.
- Comfort Factor: The korean sauna(Jjimjilbang) is about ultimate relaxation. Being constricted by a tight bra or elastic bands ruins the vibe.
- Visibility: The uniforms are made of thick, heavy cotton (usually orange, brown, or dark blue). They are designed not to be see-through, even when wet with sweat.
However, for Foreigners: If going “free” makes you too anxious to relax, it is perfectly okay to wear underwear.
- For Women: Many female travelers feel uncomfortable going braless. In this case, wear a sports bra or comfortable underwear. Just bring a spare set of dry underwear for when you leave, because the ones you wear inside will get wet.
- For Men: Boxers or briefs are fine if you are worried about the loose shorts.
Conclusion: Prioritize your comfort. If “no underwear” stresses you out, wear them. Nobody checks, and nobody cares!
Phase 5: The korean sauna(Jjimjilbang) Common Area (The Fun Zone)
Once you are dressed (with or without underwear), follow the signs to the “Jjimjilbang” or “Common Area.” You will emerge into a huge open space filled with families, couples, and friends lying on mats.
This is the social heart of the experience.
1. The Yang-Meori (Sheep Head) Towel
You will see people with towels on their heads looking like Princess Leia or a sheep. This is called Yang-meori.
- Why? It keeps your hair out of your face and absorbs sweat in the hot rooms.
- How? It’s a simple origami trick with your small towel. Ask a local or staff, “Yang-meori, please?” and they will happily show you. It’s a great icebreaker! We brought a Youtube link for you. Watch Here.
2. The Snack Ritual
You cannot visit a korean sauna(Jjimjilbang) without eating the “Holy Trinity” of sauna snacks:
- Sikhye (식혜): A traditional sweet rice beverage served ice-cold. It is the perfect hydration after a hot sweat.
- Maekbanseok Eggs (Baked Eggs): These brown eggs are slow-cooked in the sauna. They have a chewy texture and a nutty flavor. Dip them in salt!
- Bingsu (Shaved Ice): Popular in summer.
3. The Kilns (Hanjeungmak)
Around the common area, you will see door after door resembling igloos or ovens. These are the dry saunas.
- The Ice Room: A freezer-like room to cool down.
- The Salt Room / Charcoal Room: Warm rooms (40-50°C) with healing properties. Good for napping.
- The Bulgama (Fire Kiln): Extreme heat (80°C+). Do not bring your phone here; it might overheat and shut down! Enter for 5-10 minutes to sweat out all your toxins.
Phase 6: Sleeping Overnight (The Budget Hack)
Did you know many travelers use korean sauna(Jjimjilbang) as a cheap hotel? For just $12, you get a bath and a place to sleep.(But It might be hard to keep your luggage in a korean sauna.)
When night falls, people pull out thin plastic leather mats and hard rectangular pillows (which look like bricks).
- The Sleeping Caves: Some places have “cave” like tunnels for one person. Grab these early; they are prime real estate!
- The Floor: Most people just sleep on the open floor.
- Snoring: Be warned. It will be loud. There is always a symphony of snoring. Bring earplugs if you are a light sleeper.
⚠️ Safety Reality Check: Watch Your Phone!
You might have heard that Korea is incredibly safe. It is true—you can usually leave your laptop on a café table and nobody will touch it.
However, Jjimjilbangs are the ONE exception.
Because it is dark, crowded, and people are deep asleep, petty theft does happen. The #1 target is smartphones.
Here is how to keep your belongings safe:
- The “Charging” Trap: Never leave your phone plugged into a public wall outlet while you sleep. If you leave it charging unattended, it might be gone when you wake up. Bring a portable power bank and charge your phone inside your pocket or bag.
- The Sleeping Hug: If you sleep with your phone, keep it under your pillow or inside your pocket. Some locals even tie their locker key and phone together. Do not just leave it next to your head on the floor.
- Use the Locker: The safest place for your wallet, passport, and expensive electronics is always your assigned locker. Only bring what you immediately need into the common area.
💡 The Golden Rule: If you can’t touch it, lock it up. Don’t let a lost phone ruin your Korea trip!
Conclusion: Clean Body, Clear Mind
Leaving the korean sauna(Jjimjilbang) feels like being reborn. You return your uniform to the bin, change back into your street clothes, and pay your bill at the counter.
Walking out into the cool Seoul air, your skin will feel impossibly smooth, your muscles loose, and your mind clear. The initial fear of being naked seems silly now. You have conquered the Korean bathhouse.

❓ FAQ: Quick Answers for Nervous Travelers
Q: Can I go to the korean sauna(Jjimjilbang) if I have a tattoo? A: Yes. Unlike Japan, where tattoos are often banned in onsens, Korea is much more lenient.

Q: Can I wear my glasses in the sauna? A: In the Common Area, yes. In the Hot Tubs, it’s not recommended because the steam will fog them up instantly, and the heat can damage the lens coating.
Q: Is it mixed gender? A: The Baths (Naked area) are strictly separated. The Common Area (Clothed area) is mixed. You can meet your boyfriend/girlfriend or family there after washing.
