Unconscious Bathing is when a character is in some sort of bathing scenario but they are not awake or conscious. This can happen when fallen asleep, drugged, knocked out, or other ways.
Sometimes characters fall asleep and are then put into a bath by others (Forced Bathing). Other times they may fall asleep and fall into a bath (Accidental Bathing). Other times they enter a bath awake and fall asleep while in the bath.
Sometimes characters wake up while in the bath, and other times they remain unconscious until removed from the bath by other means.
