I stayed overnight both on the air side and in the public area at ICN before, and it was quite safe.
There is no free shower unless you can use a business class lounge (flying in business class, or having a gold status on an FFP). There is a spa on the basement of the terminal, though you need to clear immigration.

Thank you very much!

I checked on that website
but I still dont know how much it costs for shower

Sorry, the last reply of mine wasn't accurate. It seems there are free shower facilities at ICN.

They are open from 7:00 to 21:00.

thank you so much!!! XD

There is also a jjimjilbang (sauna) in the airport with sleeping areas, it costs 20,000KRW.

Hello,

If you are not able to leave security there is a sleep lounge in the transit hall. I have slept there myself and it is free. Good lie flat leather "chairs" free for all to use.

As for a shower (and food and drink) I would recommend the "Hub Lounge":

If you are flying Asiana or Korean Air it is $21 (USD) for entrance. Otherwise $35 (USD). It includes shower, internet, all you can eat buffet, open bar (as much as you want to drink), comfy chairs, TV, etc. A great deal for a long layover.
