I don't think that "quartzite that looks like marble" goes in that kitchen. Have you priced quartzite? It's extremely expensive. Or did you mean to say Quartz (a manmade material)?

Painting or staining isn't going to change the cabinet fronts or the design of them to be up to date. The marble look will be mismatched.

I would spend some money on lighting and backsplash. The floor looks fine - what stain are you going to do on the floor? Not a darker one - nothing is harder to keep looking clean than a dark floor.

I have to agree with artistsharonva. There is so much more that this kitchen can be. Are you happy with the layout? You don't find the angled cabinetry creates a bottle neck when going to your great room? I find angles limit space and create awkward traffic patterns. Looks like there is so much space just beyond that which could add to a better layout. If you moved that angled section to possibly wrap around the wall, you could do a bigger or longer island. Hard to tell without seeing a floor plan. You can still reuse the cabinetry if the budget doesn't allow.

In addition, the column/ drywall next to the ovens dominates the space.

The many different countertop heights creates visual confusion. I would also try take the abinetry up to the ceiling.

If it was me I would do a gut job and try to find inexpensive cabinetry or reuse the lowers and paint them if they are decent cabinets and get taller uppers.

I wouldn't waste any money on this kitchen if a comprehensive plan isn't in place. Maybe get an inexpensive stainless frig off Craigslist if I see one. You need a plan that gets to a worthwhile goal. Then do each step in a way you can afford as you move to that goal.

Lack of drawers would steer me towards changing out the cabinets. I would wait and save till I could include that in the project.

I would also want to remove those light boxes and add much more recessed lighting.

i've been thinking about your kitchen all morning. (makes a change from thinking about mine.) Before you just do a cosmetic make over, make sure that the kitchen FUNCTIONS well for you and your family and that the space is well utilized.
