A Korean jjimjilbang is more than just a sauna. It’s a place where people relax in heated rooms, enjoy hot baths, eat snacks, and spend time with friends or family.

But if it’s your first visit, the experience can be a little confusing.

Do you wear clothes in the bath? What is the locker key for? And how do you pay for food?

Here are five simple Korean jjimjilbang rules to know before you go.

Rule 1 — Keep Your Locker Key

After paying the entrance fee, you’ll usually receive a numbered locker key or wristband.

Some jjimjilbangs have separate lockers for shoes and personal belongings.

Your key may also work as a payment method for snacks, drinks, massage chairs, or other services inside the facility.

The rule: Keep your locker key or wristband with you throughout your visit.

Rule 2 — Know What to Wear

This is probably the biggest surprise for first-time visitors.

Traditional jjimjilbangs usually have two different areas.

Gender-separated bathing areas

These are the changing rooms, showers, and public baths. Visitors normally bathe without clothes or swimsuits.

Always shower thoroughly before entering a shared bath.

Shared jjimjilbang areas

These are the communal relaxation spaces and heated rooms where friends, couples, and families can spend time together.

Wear the special shirt and shorts provided by the facility.

The rule: No clothes in the traditional bathing area. Wear your spa clothes in the shared relaxation area.

Follow the facility’s signs and instructions, as some modern spas have different arrangements.

Rule 3 — Start with a Cooler Room

Korean jjimjilbangs often have several heated rooms with different temperatures.

Some are comfortably warm, while others can be extremely hot. You might even find an ice room.

You don’t need to try the hottest room first.

Start with a milder room and gradually explore other temperatures if you feel comfortable.

Take regular breaks, drink water, and leave immediately if you feel dizzy or unwell.

The rule: Start cooler. Take breaks. Stay hydrated.

A jjimjilbang is for relaxation, not a competition to see how much heat you can tolerate.

Rule 4 — Check Extra Charges

One of the fun parts of a Korean jjimjilbang is enjoying snacks after spending time in the heated rooms.

Two popular choices are:

• Sikhye: A sweet Korean rice drink, usually served cold.
• Roasted eggs: A classic Korean sauna snack.

However, food, drinks, massages, body scrubs, and some additional facilities may not be included in the entrance fee.

Some jjimjilbangs charge purchases to your locker key or wristband, allowing you to pay everything together before leaving.

Others require immediate payment.

The rule: Check which services cost extra and how to pay for them.

Rule 5 — Check Out Properly

Before leaving, return to the changing room and collect all your belongings.

Check your locker carefully, especially for small items such as your phone, wallet, or jewelry.

Return any rented clothes and towels according to the facility’s instructions.

Then return your locker key or wristband and pay any outstanding charges.

One more thing: not every jjimjilbang is open 24 hours or allows overnight stays. Check its current operating hours and admission conditions before visiting.

The rule: Collect your belongings, return your key, and settle your bill before leaving.

One More Thing: Respect Other Guests’ Privacy

Never take photographs in changing rooms or bathing areas.

Keep your phone stored away in these spaces and respect other visitors’ privacy.

In shared relaxation areas, follow the facility’s photography rules and avoid photographing other guests without permission.
