It's sort of a 'design around this' challenge, but the kitchen and red room are the only areas I would start completely over with.
The green areas aren't as difficult to deal with... it would be easy enough to turn a useless sitting area back into a bedroom and to put some much-needed doors between the bedroom and bathroom. Why people sometimes keep this space open is beyond me. Paint the bedroom to return to sanity, along with what looks like a very nice set of cabinets in the bathroom white. Lose the side mirrors and mirrored walls in the bathroom because there are other things to do than clean them every day.
The hardware in the green bathroom is most likely something inexpensive and Chinese. Probably Fuzhidao or similar,
they're all over ebay.
The 2nd bath needs to be redone completely but it's not a large area. Take out the red in the utility room and redo the half bath near the breakfast area because why the hell does a half bath need windows with shutters into the breakfast area? Do NOT use this bathroom if someone is eating nearby and you had Taco Bell or ribs the night before because there isn't a fan loud enough to cover up that chemical warfare.
A couple of the one story houses behind this one are much more my style.
