I can't read the dimensions on this, so you'd have to sketch it out to see how the inches end up being allocated. I'd plan on bathroom fights. The kids are pretty close in age. I'd try moving things around a bit and see how it works out. Take the closet in the middle bedroom off that wall (we'll deal with it later). Put the toilet across from the tub with a small linen closet, maybe some hampers. Consider a sliding door (maybe frosted glass for light) between the sink are and tub area, which allows for two people to use it at once. Add a second sink area where the toilet was. Then take out the master toilet. Slide the closet over. Put the middle bedroom closet to the right of the new master closet location. Put the shower along the outer wall with the toilet next to it. Put a larger double vanity on the back of the closet wall. The vanity depicted looks a bit small for two people/sinks, but I can't read the size so hard to tell. Might have to make the closet a few inches shallower, hard to tell. If it were my home, the kids bath access issue and larger master vanity would be my "wants". Worth playing around on paper a bit, even if it just convinces you it isn't the right choice.

Sure, this is actually the upstairs of the house that we are looking at. Yes, it would be a disaster to have that layout downstairs! Downstairs we have a small half bath. The other obvious location for a bath would be the library, but we only use that bedroom in the summer as it's ridicuously cold and there is no obvious way to run plumbing up there. Part of the reason for the existing plan is to get rid of the plumbing in the exterior wall that freezes fairly regularly. We had a pipe burst years ago before I learned to leave taps running and that was a mess! Planning to move the plumbing so that it comes up through the linen closet and the pantry below it. This will at least help with the problem. The basement under the main section of the house is concrete floor and functional, but under the smaller 1790s section where the linen closet is is crawl space. I just ordered a thermometer to put under there to track for the next couple months and figure out if I need heat tape.

If your grid is accurate and you are 1 sq = 1 ft, then you don't have enough room between the newly expanded shower and the wall for the enclosed w/c. Your diagram shows 1 ft. Also the pocket door won't fit as shown. Consider a wall between the toilet and the vanity without the rest of the enclosure if you are seeking privacy there. See how this wall between the vanity and the toilet serves to hide the toilet a little bit on these two pics below? This is a different layout, but similar concept for the dividing wall. In your space consider only having the wall right next to the vanity and not going over to the other side of the room. A wall to the ceiling would conceal the toilet area and not close in the room IMO.

I like the idea of separating the vanities. Even if space weren't an issue, I'd prefer one long vanity. I think one looks neater, less cluttered. Of course, that's pure opinion -- no logic behind it. Toilet. I'll keep playing to try to get 42" width for the water closet. And yes. He is showing INSIDE measurements. I'm 100% sure of the right answer here: Verify, verify, verify. How many times have we read threads on this site saying, "But I was so sure ____, and now _____!" Privacy on the toilet is something I highly desire for a variety of reasons. I wouldn't want a bunch of snickering kids waiting outside the door to the shared toilet while I, the MOM, was using it. I also don't want nosey kids trying to take a peek inside my bathroom and heaven forbid, what if you forgot to lock one of the doors....lol!! I consider my bedroom and bathroom my sanctuary/safe haven and I don't want intruders. There's room for both toilets in the OP's plan and with a new build, a separate toilet for the master bathroom is not something she should sacrifice on. You and I think completely differently. I'd label you the Idealist and me the Practical One. My thoughts on the above: - At a certain season of your life, those snickering kids are going to be waiting outside the bathroom door. Period. Whether you have a second toilet-closet door or not, they're strongly motivated to be near you (and is that bad?). Even if you don't actively hear them, your mind is always thinking, "Where are they? What are they doing?" A door may place the kids in a different spot, but the bottom line won't change. - I can see a lovely bathtub as a sanctuary: your own private spot, space for candles, music, your bath products, a place for you to relax after the kids are tucked away in bed. But a toilet? Especially a toilet in a dark closet? I see nothing but function. No safe haven, no tranquility, no restful moment away from the day -- just a 2-minute necessary function. - The real barrier to a bathroom should be politeness, not an actual lock. I mean, whether the door's locked or not, kids should be taught to knock and wait before entering. Consider, too, the "cost" of this toilet-closet sanctuary: More to build, more each week to clean, more bathrooms to which you must shuffle toilet paper and other goods. The more you build, the more you have to deal with on a daily basis; to a point, more is worthwhile, but where does more become tedious instead of helpful? All of the walls and doors and toilets take up too much space!! Agree. And those walls /doors /toilets create more-more-more to clean each week. Definitely go to a showroom and sit in a tub that is 72 and a tub 66 inches. That extra 6 inches is too much for me. I like to read and soak, so if you are just totally laying down, 72 inches would work. Yes, try out tub sizes for yourself. I'm very short, and I also like to read in the tub. I remember one tub (in a vacation condo) that was oversized, and it felt uncomfortable ... I couldn't relax, or I'd "slip down". Since I occasionally fall asleep in the tub, this wouldn't be a very good thing. You will feel tighter in an enclosed space that is 30" wide, than you currently feel with just the knee wall. You can easily accommodate a wider space, even 42" if you move the linen storage elsewhere, and if the wall jog behind the door is eliminated. Common sense!
