I have modular home with perimeter counters installed at the factory. We did the island ourselves (with local shop fabricating the 42" x 9.5ft U shaped counter). I've already posted about gaps b/t counter and wall, I was going to put tile up to hide gap. But I think we're just going to replace the counters eventually - not soon since DH will kill me after paying $1500 for island counter. But I noticed that on the short side of the L, I have over an inch (about 1.125") overhang, closer to 1.25" overhang on small (27") counter to right of range, but the overhang across the pot drawers/sink/DW run (7ft) varies from 1.125" to 3/4" with most of it being 7/8". The gap varies too, but is generally 1/4". The cabinet faces are flush, the countertop is 25" deep. So I'd say my wall has a big dip in the middle, may even have studs of varying projections, and they only had 25" laminate so didn't scribe the top to the wall. I haven't noticed a problem with the wall cabinets on that wall.

Just wondering if 25" was standard depth for prefab sections - I thought modular factory did all their own work (and that's why I had to go flat edge, they wouldn't radius any corners in bath or on island so we clipped bath and did island ourselves). I know you can buy sheets of laminate wider than 25". Any thoughts on how they messed this one up?

When we get around to remodeling our not-quite 2-yo kitchen, we'll probably go quartz so we don't have this issue, may or may not replace the cabinets (we'll see how they hold up). Or does quartz come in 25" depth unless it's special order?
