I like the idea of a second bathroom up the stairs, in case you have a lot of guests and need two.

Was going to say the same thing ... would you host large gatherings and need another easily reached bathroom for guests? How many guest bathrooms are on the main floor? My current house has two powder rooms, so no need to send any guests to a full bathroom.

Do you have a TV/play room upstairs that would have kids/guests that would need to use a hall bathroom upstairs?

@Sigrid @chispa Ground floor has a powder room + a bathroom (smaller than the one in question) connected to a study vs bedroom. Designed to work as backup bathroom for guests. There is also a basement powder room where the main TV/play area would be. I figure that's enough to mitigate having a hallways bathroom upstairs?

@WestCoast Hopeful Given this is our main guest bathroom, I feel like making it primarily a hallway bathroom would be a bit weird too. ie guests would have to walk into hallway to take a shower. Still appreciate the point of view.

In that case i would make it just an ensuite. Honestly two door bathrooms are not remotely comfortable.

Your third and best option is to leave it as the way it is currently constructed based upon the information provided.

I do not think you need a hall bath so just close up the wall that they framed in for the door not really sure what the problem is .There is no reason to have this available for guests since there are no extra bedrooms for use of that bathroom , FYI the closets you show are really not walkins .

Along Patricia's comment regarding closets, a six foot wide closet that provides an at best two foot wide isle is substandard and poor design.

As someone who used to be a nanny and a house manager, there were many times I needed to use a bathroom upstairs and greatly appreciated having one to step into from the hallway, even if it was also attached to a bedroom.

I would leave the second door where it is. Whomever uses that bedroom can choose to keep the hallway door always closed, locked, or not.

Just reassuring you that walk in closets can function just fine on the smaller side. Ours is 5 feet wide. Shockingly we do just fine

Why does that bathroom need two sinks? Close off the door, and the toilet closet. From the window wall, single-sin—vanit—-toile—-tub, with tub running 90° to what it is now. There will be leftover space now beyond the tub. Turn that into the hall linen closet, and make the bedroom closet wider, taking over the current linen closet.

It looks like the plumbing is already in. Rearrange walls if necessary ( add to closet?) but leave fixtures as is. If you moved the vanity ACROSS that wall where the hall door was originally you could move it forward into the bathroom and make it a single vanity. Use the space behind for additional closet space?

Hhhmm looking at the floor plan with the tub there in the original plan, that wouldn't work. It would have been good to have the tub across the now back wall where the door was supposed to be -but maybe not feasible because of plumbing.
