GC doesn't want to add a bathroom inside existing floor plan

Original Floor Plan

My vision

If I moved the wall for the closet out a little I can add a 5x7 bathroom to to the house. But I spoke to 2 GCs and they both want to build addition in the back. Should I get other GC opinion or get architects opinion?

This is a rental so I'm only looking to add a bathroom if the cost is below 10k. Otherwise I'm just going to keep the floor plan as is and rent it out. One GC said the cost to add a bathroom in the back is 20-25k. The other GC want to build a master bed and bath in the back, or a master bed w/bath and a bedroom in the back, and remove the room next to the kitchen

Have you considered just going for a 1/2 bath? The problem with trying to cram a full bath in there is that adding a bathroom to the room would be an attempt to make it a master bedroom but a master bedroom that is only 8.5'~ wide is really substandard.

Half bath will at least give you some value over nothing at all. Try a pocket door into the bedroom if you want to make even better use of the space.
