Thanks for the TopKnob # and the mention of the offset drain. Will keep that in mind for my own since I would prefer to have a small trash container under my sink if possible. I have to tell you it's really inspiring to see small kitchens done so well. Function plus style. I have a small kitchen compared to most I see on GW. Restricted by one wall taken up by a nook and windows and limited options for where the appliances can go. I contemplate swapping my kitchen with our typically unused dining room. It would make one big space, but so far no design is a home run. I keep coming back to how efficient it is to work in my step saving kitchen. Sure a swap would make it a showstopper and it would be functional, but not more functional and is it worth jackhammering my foundation and who knows what else to reroute everything? Is it worth the time, hassle and $? Would that $ be better spent updating my patio and backyard landscaping since here in S CA we entertain more outside? I struggle with the choice. I know that sounds so dramatic, me and my first world "problems". Ridiculous. Too many choices. I just want a little style to go with my function and it's kitchens like yours that remind me style can come in small packages!

I would definitely do white cabinets to break up the gray. Your current cultured marble is warm and your new bathroom elements are cool, so it already clashes. If you are going to update your vanity, you need to update your counter too, even if that means waiting and saving up money. It looks like the mirror and lights could stay regardless (or at least be a later project).

You can take your vanity door to paint store and have it color matched, then paint any cabinet or shelf. If you are okay with open storage brass shelves would look nice too.

I would not leave the cabinet just hanging out In its wall hole that way. Get some molding to cover the space between the cabinet and the sides of the hole. You will need to scribe the molding to the places where the cabinet trim sticks out more. Or, since you are painting the cabinet to match the wall, simply have the protruding trim sawed off flat. It looks like a cabinet stuck into a hole unless you add trim for the built-in look.
