Painting over cabinet doors can be tricky, depending on what material you're painting over. An easier alternative is just to replace the doors and drawers, and you can do this very cost-effectively by going for a plain melamine colour like this: If you have open cabinets instead of open shelves, it helps to keep the dust off but they still look great. Or you could go for wall cabinets either side like this:

Hi everyone, thanks for your amazing feedback so far! I had a builder come look at my cupboards last night, and he advised that they're actually chipboard with laminate front, although when he first looked at them and felt them he said they are wood but that's what he found upon further inspection. The cupboards are in excellent condition still - there is no peeling on the edges or and chips or anything like that. They must be a high quality material when originally installed. The kitchen is a stand-alone room. There is a door that goes outside to the backyard, and another sliding door that opens to the dining/living room. The kitchen window frame matches the rest of the window, door frames and architraves in the house (the top picture has the door frame visible). If I was to paint the window frame, I would imagine the door frames in the kitchen would be painted to match, correct? I prefer to keep the bench top as it is about 5 years old and in prefect nic. Perhaps I might go down the path to replace the cupboard doors as personally, I'm not a fan of the routing.

Heavy items down below, stuff you hardly ever use at the top, and get one of those little single-step step stools for anything in between. I have one ( Rubbermaid, had it for about 20 years) , it's very stable, and it gives me about another shelf level up from what I could reach in bare feet.

Hi again. Finally took the plunge and had the kitchen resprayed. So much lighter and a great job by the professionals. Hard to remember the mustard kitchen now, except the photos remind me.
