"Korean bathroom floors are always wet. There's a drainage hole in centre of the floor, where water drains down to the sewage.The advantage is you never have to clean the bathroom. You just take the shower hose, and spray everything down. One minute later, voila, shiny and clean." - (thank you Anonymous) / F.Y.I: I discuss this in my post Arrived in Korea Last Night.
Why does anyone NOT have heated floors?
