I could live with plywood counters for a few months if necessary while waiting for my dream tops to come in.

Where will that exposed half inch end up? Can you "trim" the extra half inch with a wood board placed vertically against a wall -- perhaps to support a spice shelf/cabinet on the wall?

Agree with suezbell. It should be easy to move the slab out by 1/2" and do a little creative trim at the wall. I would much rather do that than try to find something else either as a substitute or an attempted match. Unless I am misunderstanding the issue, you are making a big problem out of a rather small one.

I'd beef up the wall on that 46 inches. Sounds like a non issue , issue to me : )

Yes, to what Jan said.^^

I think I would need to see the problem but the idea of beefing up the wall makes sense right now

#2. You’ll get the job done and have the countertop you wanted.

Kudos to your granite fabricator for covering the expense associated with their error. We don't often hear stories like yours reported on houzz. I doubt the situation would be the same had you employed any of the "big box" store suppliers or the low-bid granite fabricator.

Really like PP's idea of having a carpenter make a slim shelf against the wall on one end of the miscut granite. Maybe out of a nice wood that complements your dining table (if seen from kitchen), or stone - whatever. I'd find a little shelf really nice for spices, or plugging in phones, etc (depending on where in the kitchen it is).

I don't think suggestions should be made without seeing a photo of the actual problem and the space surrounding it ...

1/2” can be worked around. But it needs your KD on site, with the big picture of how all the materials and design comes together. .

Bring the wall to the top and move on please.

It's 1/2 inch..............and am assuming no mater a left , right, or back wall and no moisture? Fur/ and drywall and done. I'm normally fairly neurotic, but not here.

Building out the wall another 1/2" sounds like a great compromise and the fastest solution to get back in your home quickly with a fully functioning kitchen. But to answer your question, yes, you can live with plywood counters for quite a while... I've done it, hated it, but I've done and my family survived.

We did plywood counters with contact paper while they fabricated our counters. I could have easily lived with those counters for many months. The limiting factor would have been when the contact paper got ratty.

Home Depot sells sheets of LAMINATE in black , 4 x 8, for 45 bucks . A perfect counter for months if you want to wait for 100% perfection. and a hell of a lot better than contact paper!. Add an inexpensive drop in sink, and you are back in "business" via your contractor , in a single day.

But..................as I said " pick a neurosis" : ) Depends your waiting/patience factor.
