Is the countertop 2 cm or 3 cm. IME, 3 cm stone (of whatever kind) sits rights on the top of the cabinets with no gap. 2 cm stone requires a plywood base, and therefore, there is usually a strip of stone laminated to the front edge to cover the plywood. What exactly is he planning to use under there?

That's very scary! Unsupported underneath so that any pressure on the top could cause the whole slab to crack. I hope the rest of the build doesn't contain more shoddy work like that. It looks like the one cabinet is not level with the ones surrounding it. Putting trim on the top to simply hide the gap is not the right fix.

We had granite installed through Home Depot. When they came out to measure with their laser device, we were told that they would not install if the cabinets varied by more than 3/16 in. We actually had to get the cabinet installers back to re-level.

It is 3/4 inch / 2cm. I dont know what they were planning to put there, he called it a scribe. I assume some trim to cover that up. That picture is only at the sink, here is the rest of it around the kitchen.

When I get home I'll post pictures of both 3cm CS counters (kitchen) and 2cm (bathroom).

Thanks sjhockeyfan325 I have never seen this like this before, so I was suspicious.

For 2 cm, it's typical to have the plywood sub-top. Often the plywood edge is hidden by a built up or mitered edge, but can also be covered with a wood trim piece when the 2 cm edge showing is preferred.

The installation looks normal except at the sink. It looks as if they did not continue the sub-top along the front edge of the sink, and relied on mastic and shims.

Here are the pictures. The first one is a 2 cm slab with a facing edge that is miter-cut. The second one is the same top taken from underneath. The third picture is a 3 cm slab in the kitchen, no plywood base.

See, now that was what I was expecting it to look like. Everything at their design studio looked like this, even the mock kitchen with my exact countertop (same edge and thickness) and cabinets.

sjhokeyfan shows good examples... here's a similar example in our second bath with 2 cm mitered edge...

Yes, I am aware of there being no build up edge (went for the 3/4" flat eased edge, that was their description of it, regretting that decision possibly now). I am trying to work with the construction superintendent to resolve the missing trim and issues with not just this but a laundry list of other items.

We have a 2 cm edge but the plywood subtops are set into the cabinets so it is a flush surface with the top of the cabinet frames, not placed on top of the cabinets as yours appears to be. I guess a trim would fix it?
