I just bumped this thread..it is full of really helpful info. there is another one called something like "the best decision I made" that you might want to read, too. Here is a link that might be useful: FAQ/Answers Bathroom Plumbing for Dummies

This is all based on you being able to move walls. The bath is cramped - nice big shower though. Narrow passageway between toilet and sink. The entrance to the room is too long and narrow. The makeup vanity is bigger than it needs to be. There's a pinch point between bed and corner of bath. Reduce 80" wall to 72", maybe down to 60" but no smaller. Put sink, toilet, shower on same wall (upper in picture) Increase that wall length from 84" to say 96"-108". The makeup vanity reduces from 90" to 78"-66". Plumbing costs will be less as there is only one plumbed wall. The bathroom and room will be more accessible if anyone ever needs to use walker/wheelchair. The wider passages will feel more gracious.

It sounds to me like you're looking for the same thing as a conventional tub/shower setup, only without the shower attached. I don't know about other brands, but Delta seems to sell "tub only" sets. We also have a 66" vanity. Sort of. GC told us when the wall was moved we'd have "about" 69" of space, so we should order 66" vanity with some filler strips. Only, in the end, we had 72" of space....oh what I could have done with that extra 6"!!! Lol, every inch counts! But I must say, I love it...we did two 21" sink cabinets with a 24" 4-drawer unit in the middle...so happy with the storage. Good luck with your remodel!

I’d do top mount solar shades. You can choose the opacity and color. We don’t have a nana wall, but we do have about 16 feet of floor to ceiling fixed windows and a sliding door on one side. We broke it up into 3 panels: two of even length and one shorter panel over the slider opening so we could have all down but still exit to the yard. They added trim to the top to conceal the mounting bracket. Multiple panels also solved our problem of possible sagging from one or two long runs of shades.
