Thanks for the responses. My daughter has a full sized bed, a nightstand, a longer dresser (under 5 feet) and a tall dresser (2 1/2 ft wide). I will post a pic of the layout later when I get back from finishing my Christmas shopping. Oaktown, in your 5ft wide bath, does the tub sit on the exterior wall, so the window is in the tub area? That is one of the options if I go with the 5ft wide and keep the extra foot of space in her bedroom. I don't love the idea of a window in the bath- and with the shower curtain drawn (they like shower curtains vs. glass) It probably won't be effective. If I go with the 6ft width, then the bath will be on the long wall, and the window will not be in the tub area, it alongside the tub.

She should have focused task lighting at the desk anyway, no matter what you decide for overall room lighting. That way she can have localized bright light for reading and writing while not having the entire room lit up like an operating room (which wastes electricity as well as just being aesthetically unpleasant). If she uses a computer at this desk, glare on the screen from overhead lighting can cause painful eye strain and headaches. Attractive adjustable desk lamps can be very inexpensive or cost a mint depending on what you get and where - if the desk is small and you don't want to waste space on a lamp, a swing-arm lamp mounted on the wall is an excellent solution. Many of that style are corded so you don't have to worry about fishing wires around in the walls. Lamps that take a three-way bulb are particularly good for task lighting.

We've always had 8' ceilings in our kids rooms, but in our new build we are doing 9'. Mainly because large bunk beds are difficult to fit in small rooms with 8' ceilings. If you aren't doing bunk beds (or the larger lofty type of bunk beds) - you likely won't need the extra ceiling height. I am looking forward to it though and it allows for the window header to be slightly higher which lets more light in the rooms and I like hanging light fixtures that don't bump peoples heads. :) Just some ideas. Your rooms sizes are large enough it will feel great either way.

You can always have something made based on your specifications, if interested I design and build light fixtures in almost any possible configuration. Feel free to browse My Storefront, all my lighting can be custom made to meet your needs.
