What would you use for closets if you enlarged the bathroom? It would help if you could post a floorplan of the now & future. It's hard for me to follow the description above and make a picture in my head.

"Will you need a fan and or light in the enclosed area?" We actually have one unit in the ceiling above the toilet that has a fan and light built in...we might get a new nicer-looking unit to replace the old one but that should be an easy upgrade. "I like that last setup you showed." Me too, but I'm still not sure whether to go with a barn door or pocket door. I think barn door has the advantage of an easier installation, but a pocket door probably could be installed leaving more room in the toilet closet. A barn door would probably look cleaner from outside the toilet closet, since you wouldn't see the hardware or the door when opened. "It would be nice to have the toilet centered in that space, but if you can keep the center of the toilet 18 inches from the sliding glass door on the wall, you should be fine." That's my worry...the toilet is currently offset slightly closer to the closet...it is about 19" from the center of the toilet to that wall, and 22" to the other wall. With a barn door installed there I imagine we wouldn't keep 18" unless we shift over the toilet. I don't know yet how expensive that would be. A smoked glass insert across from the toilet as in that pic might be the way to go. Then I still have the question of whether that wall should be flush with the window recess or set in a little. I'm thinking maybe flush with the window would be best to leave as much depth as possible for the toilet closet, and fewer edges/angles on the other side of the wall outside of the toilet closet.

Interesting perspective! Didn't think about that. My closet door is usually open. One thing that makes me hesitant about B, is additional construction (tearing a wall down, and adding 2 walls VS just adding one wall). Any other reasons B is better, helping convince myself it's worth the costs.

Have you considered having an entry to the closet from the bathroom? I’ve owned 12 homes (all primary residences as I’ve been relocated a lot for work in the past) and 4 of them had that layout and personally I would never consider going back to the layout where one would need to leave the bathroom and go back into the bedroom to enter the closet to get dressed after showering. It sounds like a small thing, but it makes a big difference, especially if one spouse is sleeping while the other one is getting ready in the morning.
