I currently have white doors, casings and baseboards in my whole house. I would like to replace the door from the hallway into the master bedroom but wondered if I would have to replace the casing and the baseboards throughout the hall and bedroom for continuity or if I could leave the white baseboards if not the casing. The bedroom has 3 interior doors as well to two closets and a bathroom. Do I need to replace them with the same kind of hardwood door - again for continuity or can I just put in one main door to the bedroom in wood and leave the others white with white casings and baseboards.
