Sure you could do this, the margin of3/4 inch means that you will always be close to a partially open or closed door, it would be better if the doors were wider. Go to the local home improvement place and look for the hardware, its there you just have not looked for it yet, the other thing is if the doors are hollowcore you may have alter them to find solid wood to attach the hardware to

Huh Having said all that I agree with Sophie, you can still do it though.

I should mention that within the bathroom there is a separate toilet room closed off with a regular swinging door.

I’m a little confused on the space you’d be saving based on the picture. Any layout pics? I don’t think it’s a great idea as I see it now

Sure, here's the floor plan. Rooms aren't labelled but you can see the toilet (room), so just to the left of that is the entrance to the bathroom and just to the left again the entrance to the small-walk-in closet. If the bathroom door were swinging and left open, it would cover the opening for the toilet room by a couple of inches. We can't swing the bathroom door the other way because it would cover the light switch to the bathroom. The toilet room door is only 28" so any further obstruction to that opening becomes rather insufferable. Additionally, in the walk-in closet, which is also pretty small, if the door swung in, it would reduce the length of the clothing rod and shelving along that diagonal wall.

No one likes an answer to their question that isn't anything that they asked.....

You have a lot in a little space. Why not do a pocket to the toilet room? Closing the door is going to be a gymnastics event only for small people. Impossible for bigger folks. At least that is how it looks. I personally would have sacrificed the separate tub/shower. Rentals get you to compromise - we have a shower only and we are fine with that. We do still have a separate toilet area.

My wife went to a movie with friends last night. I was asleep when she got home and stayed asleep even though she cleaned up in the bathroom. I (again personally) would never have anything other that a single swinging door between bedroom and bathroom. I would have a pocket to a toilet room though.

I am sure you could do barn doors. It wouldn't be my choice for sound and light.

It makes sense for the closet, but not for the bathroom. I don't see any space saving there as it opens against a wall. I agree with jln333 that the door to the toilet room is going to be an issue. I would either put a pocket door there (no room for a barn door) or change the swing on the door so it swings outward. You have to climb behind the toilet to be able to close it as it currently is.

Remodel it before you move in. Get rid of the toilet closet and tub. There is a much better layout. Or until you can afford that, take the useless door off of the toilet closet and put a real door on the actual bathroom.

Barn doors aren't great for bathrooms, even with a separate toilet room. They don't do a good job blocking light, noise, moisture, or smells. So if your significant other wakes up before you, chances are you'll hear everything they're doing in there to get ready.

Pocket doors seem like your best bet in this situation.

I love those doors! I'd hang them to swing.

Swing them out into the bedroom. No in-swinging door to the toilet. Either no door there, or a pocket door.

Yes, of course you can do what you describe. But why? And do you fully understand that these doors, designed to fit INSIDE to door frame opening will never, ever completely cover the door opening, even if you always, always take the time to carefully center the door within the frame opening...which you never, ever will? Time for a Plan B...

Get rid of the barn doors, they do not make sense in this layout. Barn doors take up twice the wall space of a swinging door. The layout in the bathroom is very tight and not conducive to more than one person's use at a time. Be sure to buy a toilet smaller than what is drawn.

I'm confused. Are the bath fixtures already in place?

If not I would strongly suggest rethinking that very poorly laid out bathroom

Aside from the fact that your rough opening may be manipulated to accommodate a barn door, does the overall style of your home support this door style? Since the show Fixer Upper, I feel like there is a barn door epidemic that really does not relate well to most homes and looks strange and out of place. Aside from the function question, I think the style question also needs to be raised for your space in order to ensure your home remains cohesive as well as functional.

Leave the bathroom door and have the closet door swing out. You're going to end up with no wall space to put a dresser or anything else.

Don't agree what your doing but Google Johnston Hardware lots of options and even one to do what you asking.
