If I were you'd I'd pose this question to Bevangel--often found in the building forum (you can locate a post by her, click her name, then email her through GW to ask her to post on this). She is very knowledgable about accessible homes/baths, etc. From another post she commented on: "Any room or closet that you want to make wheelchair accessible needs to have a wide enough door (32" minimum) for a wheelchair to get thru. Accessible bathrooms need to have a 5' diameter circle of clear floor space so that a wheel-chair can get turned around in them." So, I worry, right off the bat, that your bathroom isn't wide enough. Plus, having a glass shower front means you won't be able to put in a grab bar on that wall for use for a weaker person to get on/off the toilet.... I think that wall needs to be solid, at least from the half-way point down. If you cannot, under any circumstances move the shower's location, then I would make the closet narrower--at 4' wide only, and give the rest to the bathroom. If you can afford to cut the slab for a shower drain only (this won't be that expensive, in the grand scheme of things...), I'd try moving the shower to across from the sink/toilet and all the way "down" to the wall. Then, have your closet run across the right wall. If you draw that out, you might find you can get a wider area in the center of the bathroom for accessibility. Or, since it is a fairly square space (10x11) you might find that extra expense isn't worth it. Finally, I'd consider making the whole 10x11 space bathroom/linen closet, and building a closet on the door side of the bedroom (just a reach in). Bathroom space would look like a long bath, with lots of space in the "front"/bottom of it. And, along the bottom wall could be a reach in closet or cabinetry set up. This would give you the turning radius needed as well.

Closets and shower are reasonably sized. One caution on the pocket doors. Check with your builder to make sure that you will have clearance within the walls for the doors. We are using a lot of pockets in our new build. The builder caught some clearance conflicts that has required some changes. I think it was because of the placement of some of our truss support beams. The only other thing I see is a little problem that I am also experiencing with my master bath - place to hang wet towels! Re you going with hooks or a bar on the wall between the tub and the closet?

My first collection of comments are related to your revised drawing/plan: As I look at your revised drawing it doesn't look square. You state that the room is 6x6. But even so I think you will only get about 19-20" between vanity and toilet. Unless you got an 18" vanity, which is what I did in my East Bathroom that is 6.5' wide. If you remove the chimney you could put a window there. I've placed a small window in my West Bathroom, that previously was lacking one, and I love it. In my West Bathroom (I show in the last set of pics) I have a cast iron Kohler shower pan that is 36x60", with glass doors (French). I could see you doing something like that in your room. The curb is about 2" finished floor. Easy to get in and out of. The cast iron is a dream to maintain. Even better might be using a 36x48" pan then have 18" to one side for storage, as you can see in East Bathroom pictures, to the left of the tub. The storage could be in the form of pullouts like a pantry, or cabinets with pullouts like mine. They would be deep, so the pullouts would be very helpful for access. If you did cabinets, the lower drawers wouldn't be as deep, to allow for the toilet. The upper ones could be deeper. The plumbing could be housed in that pocket too. I like the idea of moving that closet wall to give you the width you need for the toilet and vanity. My East Bathroom; to demonstrate 6.5' wide room with 27" toilet round bowl, with 18" vanity. The floor tiles are 6x12 to help with floor scale. The pull outs at the tub are not as deep as the 30" tub, due to the toilet in the way, but are great for storage. roughing in: the pullouts, the plumbing is in there too and you can just sort of see the wall mounted tub fixtures. the pullouts come out as far as that door, just to the toilet tank: This toilet is the Toto Promenade in the round bowl. I love this toilet and would recommend it. But I love Nancy's idea of the wall mounted toilet with the tank in the wall. I have a Bidet on it now as you can just slightly see by the toilet lid in the pic above): These second comments relate to the plan where the chimney stays in place: I like the idea of expanding the shower. Here, a Kohler pan 36x48" could work well. One thing I did in my West Bathroom was a long wall niche that allows for a bit more elbow room. Its the only thing I like about having a niche, because they can get bogged down with products and trap water on the shelf, causing mold. I wipe down my shower daily following the showers. Last one to shower gets the honors. Its a quick wipe down of all walls and glass. Floor gets a clean every couple months, if that, depending on the shower load. I haven't had to "clean" my shower in 4 years, because of my daily habit (that I never had before). So glad I adopted this habit, I did not want the ugly mess that my old acrylic shower/tub combo had become. Since your wall is not an out side wall you could put a niche there. I only place 2 bottles of product on that shelf, lol. Any extra go in a basket that sits on the shower floor at the far end. I have a nice clinical shower stool in there too, with a gray seat that matches the floor. Nice to sit once in a while to let the rain shower head run on me. Having your toilet move down into the new expansion would be great. If you could move the wall 18" you could have that left wall become a wall with shallow built in 15" cabinets. Maybe a even a pass through into the closet for some things. It could even have a counter and uppers sort of like a kitchen. My West Bathroom; 5' shower space, with grab bar, niche, Hansgrohe rain shower head and hand held, and Fantech brand exhaust fan with light on the ceiling. The motor is in the attic and split into two locations in the bathroom, on at the shower and the other at the toilet: French doors, allow me to open the whole thing if needed, but I just use one normally: Kohler shower pan, in remodel process. This one has a center drain: Don't forget the exhaust fan, and a gap under your door to allow for make-up air to enter the room so the fan can work at evaluating the moist shower air.

I agree but I never want to walk through the bathroom to get to the closet, closet design is all about what you have to store in the closet . I have 100+ pairs of shoes so need a spot for them. I love my window in my walk in closet the natural light is great for putting outfits together and I also have LED lighting in daylight bulbs for the same reason. You can easily have a moveable island in the center but first change the way to enter the closet.That freestanding tub seems very close to the wall you need at least 12” there to be able to clean behind the tub.
