It's very pretty with the blue. I can see your darker wood floor to judge that situation...

Are you flipping the house?

What does your realtor say about peel and stick in the kitchen?

While it looks nice in the sample picture, when I see a marble floor....I think bathroom not kitchen. The floor does go with the cab color.

I think if you are selling and not living there go for it at that price point there is no expectation of high end finishes. The most important is to make sure the sub floor will accept peel and stick sometimes there are problems IMO you should have gone with sheet vinyl but you already have the floor.

I disagree that it wont wear well. I do have it in a laundry and a bath. Mine is Carrera marble look and tiles are square, and they are the type you use grout with. They have been on the floor for several years now, and the laundry room gets a ton of use, outside door comes into there, so it is also a mud room. They still look in perfect condition.

Imo, marble counters AND floors is just too much marble. Too much pattern.

I would prefer sheet vinyl over peel and stick tiles because sheet vinyl is a seamless install (usually). P&S are a fast & easy DIY install, though.

I have installed and lived with existing peel and stick tile floors. Never had a problem with it lifting or chipping. You have a new and correct substrate to attach them to. Upside is easy DIY replacement so long as you have a box or two of extras.

BTW, so far, so good. The room is looking great!

As far as peel & stick tiles failing on a terrace? LOL. Wrong material/ wrong place.

I think peel and stick is okay for this price point. I've used it in the pas with success in a furnace closet, but I had trouble with it over a basement concrete floor.

I'm thinking something darker--like the darkness of the hardwood floor--would be better. In theory it would flow between the other room and the dark base cabinets. Options are limited, but something as dark as this maybe.

Go with the floor tile you have. If the counters haven't been ordered or installed, you can choose another pattern Formica. Or, if you can find a ready made section of the marble Formica, bring it home and see if it works with the floor. It might end up looking just fine or only need a kitchen runner on the floor to pull it together. I was just musing out loud and should have said that 'I'm worried that it could be too much marble."

I'm NOT worried that marble looks too bathroom-y for a kitchen. There are loads of kitchens with marble counters and loads of kitchens with marble floors (just not both, generally.). Lots of marble foyers, too, so it works anywhere.
