Bottom line: for Seongsu luggage storage, use the T-Lockers at Seongsu Station on Line 2 (45 lockers: near Exits 1 and 4 and near Exit 3 among the shops, from ₩2,200 per 4 hours on a weekday); there is no staffed T-Luggage counter in Seongsu, so the next best options are the lockers one stop away at Ttukseom and Konkuk Univ. or a shop that takes bags on an app.

Seongsu luggage storage is a day-trip need: Seongsu is a neighbourhood people walk for hours: converted factories, pop-up stores and cafes across a wide area. That makes Seongsu luggage storage a day-trip problem more than a hotel one. Seongsu has less storage than Myeongdong or Hongdae, and that is the honest summary: one locker station, two close neighbours and a few shops. Figures come from Seoul Metro’s locker dataset, Seoul city, the T-Locker operator and Korail’s public data, dated October 2026.
Quick answer
- Lockers: 45 T-Lockers at Seongsu Station (Line 2): lockers 1 to 28 near Exits 1 and 4, lockers 29 to 45 near Exit 3 among the shops.
- Price: ₩2,200, ₩3,300 or ₩4,400 per 4 hours (S/M/L, weekday); weekends are higher.
- Neighbours: Ttukseom has 39 lockers and Konkuk Univ. has lockers on Lines 2 and 7, each one stop away.
- No staffed counter: T-Luggage is not in Seongsu; the nearest are Hongik University, Jamsil and Seoul Station.
- Late option: a Seongsu Subway Station shop (10:00 to 20:00) or a 24-hour hotel listing, about ₩5,100 per bag per day.
- Airport: no airport bus stops in Seongsu; the usual route is Line 2 and AREX.

1. T-Lockers at Seongsu Station Exits 1, 3 and 4
Seoul Metro’s public locker dataset (30 June 2026) lists two banks for Seongsu luggage storage at Seongsu Station on Line 2. Lockers 1 to 28 are near Exits 1 and 4. Lockers 29 to 45 are near Exit 3, between the shops. That is 45 lockers in total, so the bank is small for a station this busy at weekends; check the T-Locker screen or reserve in the app (up to 2 hours ahead) before you walk over.
Seongsu luggage storage in lockers costs, per 4 hours on a weekday, ₩2,200 small, ₩3,300 medium, ₩4,400 large; Seoul city lists ₩3,100, ₩4,600 and ₩6,100 on weekends and an extra ₩500, ₩800 or ₩1,000 per hour after four. The large locker is 90 cm high and stands an upright 24-inch suitcase.
Scan the QR code at the locker (no app needed), pay by card, bank transfer or overseas payment (WeChat, Alipay and cards, per the FAQ) and enter the six-digit PIN within about 4 minutes. It is single use, works only while the subway runs and keeps bags up to 5 days. T-Locker announced a fee survey on 14 October 2026, so check the screen. The full how-to is in the Seoul luggage storage guide.
2. One Stop Either Way: Ttukseom, Konkuk Univ. and Seoul Forest
If the Seongsu luggage storage bank is full, the same dataset lists T-Lockers on both sides. Ttukseom (Line 2, the stop before Seongsu toward Wangsimni): lockers 1 to 39 near Exits 1, 2, 7 and 8. Konkuk Univ. (the stop after Seongsu): on Line 2, lockers 1 to 22 near Exit 6, 23 to 44 near Exit 2 and 45 to 66 near Exit 5; on Line 7, lockers 67 to 79 near Exit 3 and 80 to 105 in the 2-to-7 transfer passage, inside the fare gates. Wangsimni and Hanyang Univ. also have banks. All use the same prices.
For the Seoul Forest side, Korail’s metropolitan locker dataset (30 June 2025) lists Seoul Forest Station on the Suin-Bundang Line near Exits 2 and 3: 10 large lockers at ₩2,000 and 6 small at ₩1,000. Korail’s public pricing is for the first 2 hours, but check the machine, and note the dataset is annual, so availability may differ.

3. Shop and Hotel Storage
Radical Storage had a Seongsu-dong page on 15 October 2026 with a shop at Seongsu Subway Station (10:00 AM to 8:00 PM, 4.9 from 17 reviews) and a Gunja-dong hotel (24 hours, 5 from 2 reviews), each ₩5,100 per bag per day. The Gunja-dong hotel (24 hours) is the late option here. Bags sit behind a counter, so keep valuables on you, and check the shop’s closing time against your last pop-up visit.
4. Why There Is No T-Luggage Counter Here
For staffed Seongsu luggage storage you have to travel: the T-Luggage counters are at Seoul Station, Hongik University, Myeongdong, Jamsil, Gimpo Airport and Jongno 3-ga, per Seoul city. None is in Seongsu. If you want a counter or airport delivery, take Line 2 to Jamsil, five stops east, or to Hongik University, and use the counter there: Hongdae luggage storage and the luggage storage Seoul hub have the details. Delivery from those counters to Incheon Terminal 2 starts at ₩20,000 per bag.
From Seongsu to the Airport With Your Bags
After Seongsu luggage storage, there are no airport bus stops in Seongsu; see Incheon Airport to Seongsu. The usual route is Line 2 to Hongik University and then AREX all-stop (₩4,650 to T1). With a bag, allow time for the Line 2 stairs. Read Incheon Airport luggage storage for what to do at the airport end.

Mistakes to Avoid
- Expecting a counter for Seongsu luggage storage. There is none; lockers and shops only.
- Assuming 45 lockers is plenty. Check availability, and have Ttukseom or Konkuk Univ. as a backup.
- Using a small locker for a suitcase. Only the large locker stands a 24-inch case.
- Missing the shop’s closing time. The Seongsu Subway Station shop closes at 20:00.
- Locking your phone inside. The PIN is on your phone screen.
- Leaving after the subway closes. T-Lockers work only while the subway runs.
