What's opposite the door in the bedroom?

How would changing the door affect furniture arrangement?

I think it will be fine. It's more important to make sure of the functionality of the placement with the two rooms.

opposite the door will probably be our bed. I don't think moving the door will affect the furniture arrangement. Here is the floor plan...

Is there going to be a TV?

I would put it where there is the least possibility of seeing the toilet /toilet compartment from the bed.

Is the bed going to be centered under that window?

I have to agree with Sophie. I have a pocket door in one bathroom. In fact, I have 2 pocket doors in this house, and some day, maybe next winter, I would like to change them both out. Mine is on a public bath, not a master bathroom, so that may make a difference. When I have guests, they always go to that bathroom, for showers because, it has a large walk in shower, but, rarely, go there when they use the toilet facilities. No one likes the pocket door. Since mine are original to the house, the rollers or track are now getting a bit worn, and occasionally, it has come off its track. I have to end up spending a few minutes, getting it back up on the track on occasion. That can be repaired, of course, but, since I have room for a swinging door, I am just going to remove the pocket door altogether eventually.

I also hate my pocket door, fwiw, although the hardware is very good.

I know you didn't ask about the pocket door, but I also agree with the posters above that you may not be happy with it. I like pocket doors, but I think they work better on doors that are only occasionally closed. What about a door that swings out toward the window? As for the door placement, I like it where it is because it isn't an odd or random placement, and it leaves space for a TV on the wall (even though the TV wouldn't be centered with respect to the bed).

Pocket doors are great. The new tracks that have 4 nylon wheels can be opened with your little finger:

The door is where it is so there’s room for towel bars and so that someone stepping out of the shower has a little privacy.

Yes, pocket doors for a bathroom is not a good idea. Pocket doors are notorious for problems with functionality. They often fall off their tracks, move with difficulty, are problematic to lock, and screech when rolled. Sliding pocket doors are hard to manage for anyone with limited use of their hands, such as arthritis sufferers. More dexterity is needed to slide a pocket door open and shut, using a flush or recessed pull, than to grasp well-designed, user-friendly typical door hardware.

It is better to use simple panel interior doors. Panel doors are the most commonly used interior doors for a bathroom. They have square or rectangular patterns that can range from a single large panel to eight or more small panels. The patterns can also include rounded tops and decorative finishes, as well as glass inserts to add extra glamour.

Don't listen to those, who say pocket doors are bad and they fall down. They probably didn't install any pocket in their life. We agree with the comment above with the track picture regarding the tracks. We always use those for pocket doors, you can choose the one for you - heavy duty, regular, soft closing etc., so they definitely won't be "difficult to move". The guys are doing sliding tracks since 1958 in the US.

Another questions is the slab itself and the hardware. Again there's NO problem with the locks for those doors. Not sure if American companies make the locks and pulls for the pocket doors, but European ones definitely have different styles, and of course with privacy function. And some pulls look just awesome.

So it all depends on the track, door slab and the hardware. Our advice - listen to your builder. Most of the time they know what they are talking about. Just in case -feel free to message with questions, we're happy to help with free advices.

Hope the renovation goes well for you!
