Is the sink installed already?

Sink is not installed yet. We are at the planning stage.

If the cabinets and sink are level and flat I don't know how it would increase the chance of cracking after it is installed. It may be more difficult to install, three person install instead of two. Normally installation is to set the edge of the countertop on the front edge of the cabinet, and slide it in place. With this installation you would want set the back first so you don't slide it over the sink which will already be in place, and that would take more manpower.

I agree with Twisted..as usual!

Norm, you are correct in that this type of application would require more $$. I've done an undermount farmhouse sink in a seamless application on a couple occasions. The section of countertop has to be brought in with a piece of bracing clamped across the opening to prevent the skinny bit from snapping like a quartzite twig. Also, because there's no seam, you'll be paying for the bit that's been cut out as well. Make sure they make it into a nice cheese board for you

Obviously there would be one seam, it's 14' long. I don't see the need for two.

Sorry, I thought we were discussing the need for seams behind the sink. Depending on the material you're going to have a seam for longer lengths. But if this were a 108" run in Caesarstone you could get away without any seams.

I would like to be a fly on the wall for that install.

Can't get you on the wall, but I can show you a picture of a Vetrazzo installation in an office I designed. 8' island top with a cutout for a lowered desk area. 1 piece.

I love Vetrazzo, well when someone is else paying for it. That was an easier install, no wall to contend with or sink to destroy, and it wasn't over 9' long.

Ahh Norm..so practical. i agree that on a 14' run 1 center seam is possible...just expensive and well....centered. I like the seams to the sides of the sink...dunno why, just makes me feel all comfy and cozy inside....safe like.

Where would the best place for the seam on a quartz top with a drop in farmhouse sink be?

You don't want a drop in anything.

What? I don't want an undermount. I want a drop in.

Yesica:

The only drop-in apron sink I'm aware of is the Kohler 3942. It's a nice enough sink, but I can't imagine why anyone who had a choice wouldn't get the K-3943.

I'll look at those specific ones. I have been looking at images online and the ones I like are all over mount apron sinks. Might not be common but that is what I like personally.

This is the type of look I like

Yesica:

Kohler makes a cardboard template that sits on your countertop and tells you whether or not the sink will work with your cabinets. Maybe they'll send one if you ask.
