I would be hesitant to give up room in my bath area. If you shrink it to 7 x 5 you'll be limited in the size tub/shower you can use and I'd think you'd want the largest you could put in there since this is the MBR. As the other poster mentioned, moving all the plumbing will quickly add up, and moving a toilet is usually the last thing you want to do. Whether you have a slab or crawlspace under your home will be the determining factor. I've included a drawing of how I'd probably do the area. Our last home was similar to yours and limited in closet area, so DH used the spare bedroom and hall bath as his dressing area. I would take the small closet space in your BR and add it to the hall bath closet.......then one of you can use it as your personal closet. If you don't need a double sink, the other option would be to reverse the closet/sink layout I've drawn That would then give you more closet space in the BR but you'd have only one sink. The double sink wall shouldn't need to be there for privacy.......isn't there a door at the entrance to your BR? If you really wanted to get carried away with a remodel........and the hall bath isn't needed by others........you could absorb that bathroom into your plans and make a large bedroom/bath suite! :)

Instead of the bypass doors, use bi-folds. We had the exact same thing in our old house, the bi-fold doors were great. As for the ends, we just had less-used hanging things. In one closet, we had upper/lower rods on one side. In the other room, I had craft storage in half the closet with shelving. Lovely closets, enjoy them.

As I am thinking I should be grateful that she doesn't necessarily have an excess of clothes, but she does have a lot of miscellaneous clothing items that don't fit well in her dresser or hang well. I could probably make space elsewear in her room but I like having everything in the closet because I find both of us are more likely to put clothes away if it's a matter of taking a basket of clean clothes into her room and sorting it directly into drawers. Otherwise I tend to live out of laundry baskets of clean clothes in the laundry room. It would be nice for her to have separate bins or drawers for leotards, swim, gloves/hats, etc. Our new house is better, don't get me wrong, but I did love having her dresser in her closet at our old house! Her dresser is low and wide so there was plenty of room for both hanging and shelves above. The only items we hang are dresses and a few "nicer" outfits that wrinkle more easily, but she does have dance costumes that need to hang and they are bulky. Maybe i could do shelves on the left, drawers in the middle, and rod on the right? Or double rod? It would probably be pretty short, what's the minimum amount of rod that isn't ridiculous? i was originally planning on using the door as hanging space for scarves, belts, jewelry (she has a lot for a 10 year old because she has awesome young aunts who give her hand me downs, and it's still a mix of "real" and dress up jewelry, but it's not unreasonable) but I have found that in doing that in my hall closet in the past I didn't love it because stuff was always falling off or swinging when the door opens and closes. Has anyone found good door/hanging organizers they like? Maybe mounting bins or baskets? i was also thinking there might be a way to use the dead space in one of the closet corners for a laundry basket, but would it be too hard to get in and out? Hmorton, were your shelves L shaped? That's something I've been considering. I also like the floor clear, unless it is something easy to vacuum around. It's also possible I'm going about the room backwards. Talkey_sue, I've been working on putting together ideas for a built-in because her dream bedroom is a daybed surrounded by bookshelves under the window. I was planning to incorporate drawers under the bed, but I was thinking they'd be more for blankets, pj's, and stuffed animals. She also has a million "collections," and I thought rather than fight her on them i would try and incorporate closed storage somewhere for her to keep some of her clutter. Maybe I should think about ways of including clothing storage as part of that. When I get home I'll take a picture and measure it. I can feel the brain block finally starting to unblock, so I appreciate the suggestions!

Consider using LED Tape lighting around all sides of the inner door trim to project light into all shelves. Attached an example image. American Lighting Trulux is one example of good quality LED Tape.
