The closet doesn't need to be more than 2 feet deep. Any deeper and things just get lost in the back. You need to make a drawing that's to scale and shows dimensions of all walls. Is there no window in the room? Does the door really recess into the room like you've shown? Don't forget that walls have thickness, too, including walls at both ends of the tub. I don't understand why you have a small 48" vanity on a bare 12 foot wall.

Where is the hall closet door and which way does it open? What do you keep in the hall closet? The toilet seems cramped in that corner.
A full-access ADA bathroom with a roll-in shower is a good idea, and there must be diagrams for ADA bathrooms online. You seem to have plenty of space, and the closet can be reduced if needed.

I would suggest rotating the toilet 90 degrees and placing it on the same wall as the shower. Make sure you have 48" between the tub/shower and the vanity. Can the closet be accessed from the other side of the wall?

For a guest bathroom, there’d be no need for a double vanity. I’m sure you have plenty of other uses for the space. Keep the toilet as accessible as possible IMO.

Catbuilder, no window. I don't need a large vanity because it is used like a powder room. Guests only, but I want the shower since the small bedroom is next door. No the door doesn't recess. Yes, I put the 6" in for the wall, but the dimensions would change if I needed a second wall if I put a tub.

Tangerinedoor, I am thinking about a roll-in shower, You are right in that it is an great idea. The toilet has to stay where it is.

Felizlady, the door opens into the hall. The closet used to be where the old furnace was. We moved it into the attic so we could have a coat closet and deep upper shelves to keep luggage there. We can make it less deep if we had to.

Norwood, I would love to turn the toilet, but my GC told me it would be pretty expensive. There are 18" on the left side of toilet to the wall, so if we tried to use the same hole in the concrete, the toilet tank would stick out by 6" or more. The closet door has to stay in the hall.

The 12 ft long room has a lot of wasted space on that one wall, I know.

I will draw it out with dimensions and post the diagram.

We will be moving in a year, so we want to spend as little as possible.

Each square = 4".

If the sink cabinet is on the long 12 ft wall, there are only 31" between countertop and the shower and 8 ft of that wall will be unused. Not enough room for ADA.

If the sink cabinet is on the shorter 7.5 ft (90") wall, by the toilet, there are 54" between wall and shower, but only 29" from corner of shower to corner of the countertop. Not enough room for ADA.

So ADA is out, unfortunately.

Code states that 24" is minimum requirement in front of toilet.

I know there is a lot of wasted space, but this entire house is that way. Master bedroom has wall to wall and floor to ceiling windows on one entire wall (28 ft). Can't put anything but a treadmill there. It is also 28 ft x 27 ft, plus 3 walk in closets, plus 1 1/2 baths. I had never heard of having two bathrooms in the master bath.

Thanks.

I can see that one dimension of the bathroom is 12', but what about the other dimension? I don't see it anywhere.

It's hard for me to be helpful here because the diagrams are so hard to make out.

It looks like it might not be obvious to posters that when you have a curbless shower, the shower floor is contiguous with the bathroom floor, so you can use the space of the shower to move around the bathroom easily if you're disabled. It's not like a tub or a regular shower: if you plan right, you can take advantage of the space that the shower occupies.

Swap the spots for the shower and the sink on your diagram. You need more space for getting to the toilet.

You're planning to sell soon? Right now, you're sacrificing a well-laid out, valuable, bathroom for a deep closet that will be impossible to get things in and out of. If you were a person in the market to buy a house, which would you rather?

Yes, turning the toilet direction would entail redoing the significant plumbing in that area at significant cost. For a powder room and an occasional guest bath, I would just want what exists to be clean, usable and comfortable. Once the function is right, then you can add wallpaper, new paint, art and accessories. Add a mirror that looks like a window, or a wall-hung window with a photo or picture attached the back showing a landscape, a city scene, or, for a laugh....a photo/picture of three people as if they are looking into the bathroom through the window.

If you are moving within the year, do not bother with this. You will not get your money back, and you won't even get to enjoy the fruits of your reno.

Tangerinedoor, did you click on the picture so that it opened up? They are large on my laptop, but maybe you are using a phone. 144" one side and opposite side 144" - 45" closet and wall = 99" for shower and toilet. 48" + 24" + 27" = 99". The short wall shows 90". The room is 12 ft x 7.5 ft at its largest. I am not sacrificing anything. The current shower is acrylic and 33" x 33". The shower needs a floor drain so I can't be swapped for the sink cabinet. The toilet can't be turned. It is what it is. GC has already looked at the toilet. Huge cost to dig out concrete and replumb.

And...I always go for storage space in a home. And...I had no intention of making it ADA. That was something you mentioned.

Felizlady, I like the idea of a picture that looks like a window!

RTHawk, I know, but it is really ugly. Toilet 30+ years old, Enormous L shaped, black cultured marble counter with scalloped sink, yellowed, beige acrylic shower, horrible triangle medicine cabinets, bad mirrors, particle board cabinets what are too bad to be refinished. 75-85K kitchen with crappy bathrooms will not sell here. Plus we are lakefront. We bought it thinking we would stay here, but now we want to be near grandkids now that we have them. Master bathroom is pink, beige, and black!

The bathroom was built in 1966, but I guess the previous owners remodeled in the 70s. I think it was originally a 850 s.f. cabin.

You can see the drywall that had brown paneling from the 60s. Then, they covered it with more drywall that looked like wallpaper. Then, they added the oak headboard. All of that is being removed because painting it did not work.

So the bathroom needs remodeled.

Crown molding in a bathroom. I don't think I have ever seen that before.

They spent thousands of dollars on oak. The living room is 35 ft x 28 ft and it was covered in the oak beadboard paneling. They had a suspended ceiling and the grids were made of 1" x 4" oak boards. Expensive. We used them to cover two ugly ceiling beams, and we still have oak boards left.

I guess I don't understand the OP's request for help with a floor plan when the current floor plan is not negotiable.

Why would I bother to spend my time with suggestions?

No more. Bye.

Wow. I was specific about what I needed help with which was choosing either a tub or shower and which wall to place sink cabinet on (next to toilet or across from shower/tub).

I am sorry you feel you wasted your time.
