Hello,

I will be landing at ICN at 430am in the morning and my boyfriend won't pick me up until 6am due to bus travel time.
I would like to take a shower at the general public shower and I was wondering about the operating time.
On some website, I saw that there was a set time and on some it was 24h. Is it 24h and if not, what can I use to shower at that time?

Thank you for your help.

All of the public shower facilities in T1 and T2 are 24-hour.
You have 30 mins free.
If you look at the Incheon website you find all the location information.

If you have landed at Incheon, your choices for a shower are limited. Spa on Air is one choice located on B1 of the arrival hall. It is open 24 hours and there is a small fee to use it. You might also consider using the Capsule hotel located near the airport train area. This also has a fee. These two facilities are located outside of baggage claim.

If you are leaving Incheon airport (flying to another destination) and have gone through security, then there are shower facilities inside, although they may charge a small fee for the towel. There are also lounges that may have showers. These facilities are not available for arriving passengers. If you are transiting, then you can access it. But if you have flown into Incheon airport and are not transferring, there will be no way for you to get to these showers.

Can't even count on a shower at the Asiana business lounges. Attendant told me she didn't even know how long the wait would be.

Just want to add that Spa on Air had a really long line 4-5am caused by people staying overnight for the early flights.
There is limited public transportation for really early flights, so people choose to take the last bus to the airport at night and sleep in lounges.
