Cost converting spare bedroom into a bathroom

start from at least $20,000 just for fixtures and finishes and then add on for moving plumbing and extra for a concrete floored house...the last new bathroom we installed in a non bath room cost about $40,000 but, as you said, it depends.... can you share a floorplan of existing house with dimensions ...not just the bedroom you want to sacrifice and what are the floors, walls, windows and roof structure built out of?
