My parents house is like that, but there’s a wall with a wide doorway into the area with the vanity, so it’s open but also easy to close off by just putting a curtain rail up. It’s also oriented to the room such that if you only use enough light at the vanity to wash your hands for a midnight potty run, it really isn’t enough to bother someone in the bed if you place the bed sensibly. Getting ready in the morning would be trickier if you needed to do makeup and so on so needed proper lighting, so that’s where a screen or a curtain would come in.

What? You need to post a picture or a link to show us what you are referring to.

I'll be a contrarian. I would never knowingly rent a room with a shared bathroom in the hall. That would be a complete pass - I don't even like having to use a hallway bathroom in a sleeping situation in which I would share with friends and family because if I need to use it in the night I would have to wake up more/get more decently dressed and I hate having to shlep stuff to take a shower or perform normal grooming stuff in a bathroom. I don't have the horror of viewing a toilet from a bedroom that some houzzers seem to have. It certainly wouldn't bother me on a temporary basis. I have a master bath in my home and I can't remember the last time I actually shut the door. I don't have issues with smells or humidity but perhaps that is because my Toto washlet has a built in deodorizer AND I have an excellent Panasonic fan which runs based on ambient humidity levels. I don't generally even have condensation on shower doors or mirrors after exiting let along huge amounts of humidity wafting through my bedroom. The question really is one of economics. There is a cost to installing the bathroom and OP would need to decide whether they would make up the expense by having increased rent and/or renting it out more frequently. Certainly any prospective renter would see a picture and determine whether they wanted the ensuite with a curtain in the room or use of a bathroom in the hall. Also resale value is a red herring. At such point that OP wanted to sell it would be relatively inexpensive to convert the bathroom into a closet if having the ensuite in that room was a negative.

Thanks! I'm in the Chicago area - I do have someone who has done other work for me and would do this (again pending material and his time availability)! He indicated that tile would be no problem, but the vanity would be a potential issue. Thinking I could go with something like the above 66" vanity and build out the right wall section and possibly put some decorative/recessed shelving there. Thoughts??? Unfortunately I suffer from analysis/paralysis and it takes something like this to force me into action. After 2+ years planning my kitchen, it was the breakdown of several appliances that forced me 9+ years ago to redo my kitchen. For my basement, it was my teenage daughter and husband complaining that we only had the kids here for a couple years and had to do it (and that was really short-fused to force me). Timing was perfect given the pandemic the following year. So - this may be just the right trigger to get me moving. My master bathroom and deck would be next :).
