" The island is offlevel quite a bit (Cabinet was not level, but no shims at all to make it right?) "

They install to the cabinets, the cabinets should have been level prior to the fabricators installing the tops, they could have refused to install the tops and probably should have until the cabinets were level. The rest, the pictures do not really show much to be an issue to my eye. Except possibly the scratch, if that is what it is.

“The island is offlevel quite a bit (Cabinet was not level, but no shims at all to make it right?)”

I agree with @millworkman that this is the true problem. And the sink, which would not be able to be installed correctly with out-of-level cabinets. The fault lies with both your cabinet installer and your counter installer. Installing level cabinets is Cabinets 101 that the apprentices learn the first month. And the counter installers should have refused to proceed with their installation until the cabinets were level.

I am a fabricator. you have legitimate complaints about the install. the smeared silicone is a characteristic of sloppy installation. Done properly with taping prior to caulking there is NO residual silicone on the cabinets or countertop underside. Unfortunately the taping adds time to the install so many shops just squirt and smear. The off level issue is a problem but not necessarily all the countertop installer fault. if a cabinet is very much off level an installer can either shim it way up (sometimes 1/2 inch or more) which is a conspicious defect or 'split the difference" to minimize the slope. Better is when the field measurer checks the cabinets are level and notifies the homeowner if the cabinets are so bad they need to be reset. The "cloudy areas" are likely just the expected appearance of your selected material. The white lines are scratches. The adhesive at the inside corner of the seam is unacceptable. Overall you got a lot to complain about but the job is so poor I suspect you got the quality your supplier considers normal.

@M Miller The sink is not angled correctly from front to back, it has nothing with the cabinet, which is actually level in that area. Only the island is off.

@Granite City Services

Yeah ... seeing the mess they made with the epoxy on the ground and the silicone was a red flag to me, adding this to the island not being level, the sink not having silicone on the inside perimeter and being angled wrong ...

As for the finish of the slab .... i mean it's hard to see on the pictures for sure but i feel like it goes from being glossy to dull in random areas .... looking like a mirror or glass table that had swirl marks from a rag, looking like it was not cleaned correctly.

When you say the sink "is angled wrong", do you mean the reveals (the amount the stone overhangs the sink) are off? Please be more specific.

There should be little exposed silicone at an undermount sink even on those with negative (the top overhangs the sink) reveals. The silicone that does the waterproofing is about an inch wide and is squished between the sink flange and the bottom of the stone. A topical bead is nearly useless.

If there is no silicone to function as a gasket, you'll have a leaking sink with a permanent black/brown mildew/crud line that can't be cleaned. Can you slip a steak knife between the stone bottom and the sink flange? Try in a few places please. If so, the sink must be dropped, the flange and stone bottom cleaned, silicone applied, and the sink strapped, not clipped or blocked, back in place.

What is going on with your backsplash please? Why does the gap between the deck and splash vary so much in your 3rd picture please?

Yes sorry, english is a struggle sometimes. Yes the reveals of the sink are off due to the sink being ''twisted''

A steak knife does fit in some areas between the stone and flange ,,,,

I also just got home and look at the job again overall to realise that the cutout line isnt straight either .....

Is this normal for cutout lines ???

As for the backsplash .... i realised the counter isnt perfectly level in the corner leading to a bigger gap on that end...

Thanks for the responds btw, helps more than you might think ...

It is not normal for cutout lines. You've got some real hackery going on here.

I know this is an old post but wondering shich MIS countertop is this. We have miraggio and we had swirl and different sheen marks

This is the Calacatta Botanica
