a lot depends on wether it's a blank canvas or not. It's not only the prep that eats into your time but also other considerations like, "is this the customers only working bathroom, if so, potware out at start of day and back in at end of day", all these things take time, and sometimes you have to chuck in this half an hour a day gratis, as the next guy that quotes won't have thought of it and gives a stupid low price.
