Korea Coin Laundromat How to Use — Wash and Dry Large Items, Price and Time Guide
📅 Updated: April 2026 | 🧺 Based on direct experience using 코인세탁소 across Korea
A coin laundromat (코인세탁소, pronounced "ko-in se-tak-so") is a self-service laundry facility commonly found throughout South Korea — in residential neighborhoods, near universities, and close to guesthouses. Most operate 24 hours a day, 7 days a week, with no staff on site. They are especially useful for washing bulky items like comforters (이불), blankets, sleeping bags, and winter coats that cannot fit in a regular home washing machine.

① How Korean Coin Laundromats Work
Walking into a 코인세탁소 for the first time can feel a bit confusing if you don't read Korean, but the process is actually very straightforward once you know the steps. I used one every week for six months while living in a studio apartment in Seoul, and it quickly became part of my routine.
Step 1 — Choose a machine: Select a washing machine based on load size. Small machines (7–10 kg capacity) handle everyday clothes, while large machines (12–20 kg) are designed for comforters, duvets, and blankets. The drum size is usually labeled on the machine door or above it.
Step 2 — Add detergent (if not provided): Many modern 코인세탁소 machines automatically dispense liquid detergent included in the wash fee. If the machine does not include detergent, there is usually a vending machine selling individual-use packets for 500–1,000 KRW. Bring your own laundry pods for the most economical option.
Step 3 — Pay and start: Insert your items, close the door, select the wash cycle (usually just one standard cycle is available), then pay using coins, card, or app. The machine will lock and start automatically.
Step 4 — Dry: Move your laundry to a dryer (건조기) after the wash cycle ends. Insert coins or pay per unit of time — typically 500 KRW per 10 minutes or 1,000 KRW per 20 minutes depending on the facility. For a comforter, budget at least 3,000–5,000 KRW for a full dry.
② Machine Sizes and What to Use Them For
Choosing the right machine size matters — an underfilled large machine wastes money, and overstuffing a small machine leads to poor cleaning results.
- Small (7–10 kg): T-shirts, jeans, underwear, towels — everyday laundry for 1–2 people
- Medium (12–15 kg): Bed sheets, light blankets, multiple loads of mixed clothing
- Large (18–22 kg): Winter comforters (이불), thick duvets, sleeping bags, heavy coats, curtains
For a standard single-person comforter (싱글 이불), a 12–15 kg machine is usually sufficient. A king-size duvet typically requires an 18 kg or larger machine. Attempting to cram a thick comforter into a 7 kg machine risks damaging both the machine and the fabric.
③ Price and Time Guide — Comparison Table
| Item / Size | Machine Size | Wash Price | Wash Time | Dry Price | Dry Time |
|---|---|---|---|---|---|
| Everyday clothes | 7–10 kg (small) | 3,000–4,000 KRW | 30–35 min | 2,000–3,000 KRW | 30–40 min |
| Bed sheets / blanket | 12–15 kg (medium) | 4,000–6,000 KRW | 35–40 min | 3,000–4,000 KRW | 40–50 min |
| Comforter / duvet | 18–22 kg (large) | 6,000–8,000 KRW | 40–45 min | 4,000–6,000 KRW | 50–70 min |
| Sleeping bag / coat | 15–18 kg (large) | 5,000–7,000 KRW | 35–40 min | 3,000–5,000 KRW | 40–60 min |
* Prices vary by location and facility. Prices in major cities like Seoul and Busan tend to be slightly higher than rural areas.
④ Payment Methods and Practical Tips
Payment Options:
- Cash coins (동전): Traditional method — bring 500 KRW and 1,000 KRW coins. Some older machines still require coins only.
- Card terminal (카드 단말기): Most new machines accept credit and debit cards (Visa, Mastercard, domestic cards). Look for a card reader on the payment panel.
- App payment: Popular apps like 런드리고 or facility-specific QR codes allow contactless mobile payment. Increasingly common in newer facilities.
Top Tips for Large Items (Comforters & Duvets):
- Roll the comforter loosely and stuff it evenly around the drum — do not compact it into a ball, as the center won't get clean
- Always check the care label: down-filled duvets usually need a gentle/delicate cycle
- Add 2–3 dryer balls (if available) or tennis balls inside the dryer to prevent clumping
- Run an extra 10-minute dry cycle to ensure the interior is fully dry — damp comforters develop mold quickly
- Go on weekday mornings (before 10 AM) to avoid waiting for a large machine
Finding a Coin Laundromat Near You:
Open Naver Maps (네이버 지도) or Kakao Maps on your phone, type "코인세탁소" in the search bar, and you'll see all nearby locations with ratings, photos, and user reviews. Most listings show whether the facility has large machines. Google Maps also works with "coin laundry" or "코인세탁소" in Korean.
❓ FAQ — 7 Common Questions
Q1. Are Korean coin laundromats open 24 hours?
The vast majority operate 24/7 with no staff on site. A few smaller facilities may have limited hours (7 AM–midnight). Check the posted hours on the door or look up the listing on Naver Maps before going late at night.
Q2. Do I need to bring my own detergent?
Not always. Many modern facilities include liquid detergent automatically dispensed at the start of the cycle — the price is built into the machine fee. Check the machine for an "액체 세제 자동 투입" (automatic liquid detergent) label. Bring detergent pods as backup just in case.
Q3. Can I wash and dry a king-size comforter here?
Yes, that is exactly what the large machines (18–22 kg) are designed for. A king-size comforter fits comfortably, and the industrial dryers get it completely dry within 60–70 minutes. This is one of the most popular uses of Korean coin laundromats.
Q4. What if I don't speak Korean — can I still use the machines?
Most modern machines have simple icon-based interfaces with numbered steps. Some facilities also have basic English instructions posted. In general: load items → pay → press start. If stuck, the machine display usually shows a phone number for the owner, who can assist remotely.
Q5. How much change do I need to bring?
If the facility only accepts coins, bring at least 10,000–15,000 KRW in coins for a full wash-and-dry cycle with a large item. Most convenience stores (편의점) nearby can break larger bills into coins for you. Better yet, choose a facility that accepts card payment to avoid the hassle.
Q6. Is it safe to leave my laundry unattended?
Generally yes — 코인세탁소 facilities in Korea have a low theft rate and many have CCTV. That said, it is courteous (and practical) to return promptly when your cycle ends. If you leave laundry sitting in the machine for a long time, others may move it to make space.
Q7. How do I know when my cycle is finished?
The machine display counts down the remaining time. Most machines also emit a beeping sound when done. Set a timer on your phone based on the displayed cycle length so you don't forget to come back.
📝 Full Summary
Korean coin laundromats (코인세탁소) are clean, affordable, and widely available self-service facilities — a lifesaver for anyone without a home washing machine or who needs to wash bulky items. Washing costs range from 3,000 to 8,000 KRW depending on machine size, and drying adds another 3,000–6,000 KRW. Most facilities now accept card and app payment in addition to coins, and they operate around the clock. For travelers or new residents, searching "코인세탁소" on Naver Maps is the easiest way to find the nearest one. Bring a laundry bag, time your visit for off-peak hours, and give thick comforters an extra drying cycle to ensure they're fully dry before taking them home.
