You should have at least one ceiling light in the bathroom. (possibly two especially if you read in there) In the closet I'd recommend one 3 bulb fixture in the center. For the bedroom a ceiling fans in the center. Here's a few ideas.

My husband is chomping at the bit to paint it white. I know that my daugher will most likely have the door open all/most of the time. My gut tells me since it's a very large closet (almost another bedroom in itself) and has lots of light, that I should go with a color (maybe the same color as the adjacent bathroom which is Turquoise Mist (Porter).

First, measure your clothes to determine how much short. medium and long hanging space you need. Rather than one set of drawers under the hanging rods, have a stack of drawers. Instead of bifold doors, have double doors. You can mirror the inside and use both doors to get a good look at your front and back. Here's an example of a closet with double doors. These doors are very wide. I have 18" wide doors, for a 36" wide opening, which is plenty. Inexpensive door mirrors are around 14-16" wide and 60" long, so they can fit easily on the inside of the closet door.

I am so super bummed I found this article! I wish we would have made our one-sided walk-in closet narrower as we ended up with a very small bedroom! We settled on 40" deep after reading this article the closet took valuable space away from the bedroom which is 10' x 11'. I would have done ANYTHING for an extra 5-6" which would have made the room 5' x 11.5" and the closet 36" deep which is plenty for a side-entry walk-in closet. We wanted to do walk in instead of reach in because of the flexibility of the bed configuration and gaining more wall space in the room. But we ended up with a small bedroom and a large closet. Don't make the same mistake we did!
