Nice flooring. I would ask about epoxy grout for a kitchen. Could you include a pic closeup of your door drawer combo. Are they solid wood?

Those cabinet doors are right on trend. In fact, there isn’t one thing that needs changing other than the lighting. You need a better lighting design. And new floors. No tile unless you want to trap your DW and not be able to replace it. LVT.

No, it is not possible to change a beveled edge to a flat profile. You can’t add wood back that has been removed.

LVT. Much thinner than tile. Easy to DIY if you have a mind to doing so.

Adding drawer pulls would be a nice update.

You would have to completely refinish all of the cabinets 100%. Which is way more labor than painting even. An average professional paint job for a kitchen is 7-9K. I would expect the labor to remove a factory tough clear coat, modify the doors, restrain the doirs, and give them the equivalent factory tough finish, would be almost double that of painting them. Because it’s almost double the labor.

Love ‘em, or gut the kitchen and start over with new cabinets.

I agree with getting your quartz counters now and waiting on a banquette.

Not sure what your style is but new flooring and quartz countertops with some hardware added to the cabinets could make this kitchen very sleek looking. i would also paint the adjoining room with a wall color other than white to give it some depth and feeling. Do you want to stick with dark green as your accent color? Do you want a country look or more urban? What is your desired look?

I remembered a thread where the poster wanted to install rounded edge slab cabinets. She got a number of responses and photos of beautiful cabinets in that style. I couldn't really see your cabinets, but Here is the link to that thread

I hope it is relevant to, and makes you feel better about, your rounded edge cabinets.

Just for fun, I just did a Houzz search for slate floor, maple cabinets and chose midcentury for the style, to get less rustic results. I smiled when I saw the very first photo with its dark green island and had to share.

Here's a medium gray counter (on left) which seems pretty classic. I think you could go darker but you will have to see what you think in your light.

Adding pulls to the cabinets would make it feel much more modern immediately, IMHO, and would be far far simpler than trying to change the cabinet profiles.

O, you have so many choices for your colors, depending on what's going on with the rest of your house. What about coppers, blues? The green in the first photo doesn't read rustic because of the other modern elements, and those elements will be important to highlight your neat cabinets no matter the accent color you choose.

I looked at the Wilsonart and without seeing it in person, it looks like it would be pretty with the floor and cabinets. I think a counter whose tones match the cabinets will also be pretty with those floors.

I'm wondering if you've considered a wood look tile that's just a bit darker than your cabinets. That to me opens up some possibilities for your counters and again, to me, seems to fit a midcentury look well.

Have you looked at Houzz photos of midcentury style kitchens?

Right before I signed off, I was looking at this photo with green tile and medium toned slab cabinets and thinking it was a great look. So, yes, a more olive green or sage would be great.

I agree your chairs also will look great. I'm not crazy about the table base with them. I think it's might look way too leggy, like a pipe explosion, with those chairs. Would you consider a parsons style table? There's lots of reasonably priced ones out there and their simple lines show off that style of chairs.

Don't worry about the fabric for the banquette just yet. You can pull in the copper (and green) in your fabric, in light fixtures, and certainly accessories.
