less than 10 minutes and i don't miss anything. 15 if i wash my hair. i don't like to waste too much water. and i say 15 minutes but only because my mom and sister both take 30+. my sister is terrible and takes an hour to an hour and a half and its frustrating when i have to get ready to go to work. i think its ridiculous to spend an hour in the bathroom if you live with other people.
