I live in Cleveland Ohio and am looking to remodel and update my 35 year old bathroom and bedroom. Looking for designer who won’t break the bank. Thank you.

The best way to approach this is to first have an accurate diagram of your entire floorplan with dimensions of everything. The last thing you want to do is to spend a great deal of $$$ adding onto your home with a dysfunctional layout that will reduce the value of your property. I've seen additions that turn a functional floorplan into something that is not at all functional and you don't want to go there. None of us can give you any advice with the information provided other than seek out an architect. You could get better advice with the floorplan and its dimensions including doorways and windows and closet areas.

The bed is a platform...you may want to rethink using a duvet because tucking the coverlet under the mattress shows the bed to full advantage.

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.
