You are going to want more than 32" for the toilet. 36" is standard (and perhaps even code in some areas???? Not here in Maine but I heard people saying that on other forums...) We have 34" and it feels fine but I dont think I'd want to go much tighter. You could solve that simply by flipping the closet and shower. So, have your shower -rotated 90 degrees and witha glass end wall- at the end of the tub (which is a nice setup you can see in many bathrooms, the tub deck can actually protrude under the shower glass wall and be a ledge or seat in the shower). Then the passageway moves to the left, and you can steal a bit of space from the other closet for the toilet. Either that of have a shorter vanity. 48" isn't a size I'd fight for. It's too short for a double vanity, really (unless you're using one of the new two-faucet 'trough" styles) so why not go down to 42" and have a better toilet area? For resale, though, you should consider a double vanity. Some people I guess expert truly huge ones, like at least 5+' long. But you CAN get smaller ones, Ikea has some great ones for tight spaces. But if you're not selling anytime soon, do what YOU like!! (But I still think you'll want more toilet space...)

Hopefully whoever is drawing your plans can help with the code stuff. There are some here that are good with that stuff. I'm not one of them, but I have picked up some stuff reading here. I think if you prefer the style where the closet is accessed through the bath, then I would definitely try for a door to the toilet. I would keep it in the footprint of the old hallway as you drew, but nudge the bottom wall down even with the bedroom wall to get 60 inches. Leave the shower as is. Consider having the door open into the bedroom so it doesn't interfere with the WC door, or consider a pocket door. You could also use lateral hinges, and that opens the option of designing the door to blend with the wall for a hidden room look. I think you should reconfigure the closet a bit too. Only 12 inches between hanging rows will almost certainly not be enough to allow access to the back half of the rows. I'd guess you might get away with it for shallow rows, but I think 48 inch rows will need more space. Since narrow doorways are 24 inches, I'd guess that would be a decent minimum, but 30-36 would probably be more comfortable. I really haven't read much about closets though. Hopefully someone with some insight will be able to comment. Those windows make things interesting! I sense you are having the same issues I did trying to design around them, though I think it can be done.

assuming (until I see the original floor plan) that the bathroom set up / location is pretty much set -- move door to bath down to bottom of image, make vanity a one-vanity / two sink option to the top of the doorway, move window over the 12 inches you say you can move it, put tub down by exterior, shower next, and toilet to the top. Use frosted glass on the window, and set it higher, and maybe narrower, for privacy. Depending how you work on the exterior view of the house, it does not have to match the other windows. It's not like your house is symmetrical to begin with. (As a possibility, you could make the window on the right side of the door match - without frosting - what you need to do with the Master Bath one?)

1.Have the bathroom entrance from closet? or keep them separate? Separate entrances are generally better, but the entrances right next to each other as indicated is the second best option. Saves walking through the wet bathroom unnecessarily, and waiting or disturbing the person using the bathroom to get to the closet. 2.General Bathroom layout - any better layouts? with current layout our vanity can't be more than 4ft, will it be small for this bathroom? If you're still planning, dimensions aren't fixed as with some renos. You can often shuffle things around if you need. The bathroom is decently sized, but not massive. Don't cram a 7ft shower into it, and waste valuable space. The layout below shows a 3'3"x4'7" shower, and leaves space for a 6' vanity Do let us know how this fits into the entire plan.
