If you were fortunate enough to move into your home with the doors, cabinets, window sills, mouldings and shelves already white and you like it that way: THANK YOUR LUCKY STARS!
This is what my entire home looked like when I moved in. Oak. Everywhere. Oak.
I know some people would be perfectly happy to have it. Here's one of my many, many doors to be painted. I've already painted over the brass handles.
