Home Depot sells two types of sink clips which can be used on channel type mounting. I don't know if they would work for your install, but you could take a look at them, return if they don't work. They are usually on a "Chip Clip" in the sink asile. Hope that helps, Dan Martyn

I have a stainless drop in. I don't understand all the talk of crud catching in the lip, I don't find that to be the case. Regular cleaning around the sink area every day makes that a non issue for me.Having never had an undermount sink I can't say, but it would seem to me that more crud would catch in that area than in a top mount. I've never dented a stainless sink, I would guess you'd have to drop something pretty heavy in it to dent it. I guess it depends on how thick your steel is? But I do hate the water spotting on the stainless. Everything has its trade offs I guess. For the most part I find the drop in stainless pretty tough and easy to care for.

Is there a cabinet below the countertop or is it open? If so, look into chromed pipes and plumbing fixtures, they can be very attractive if plumbed neatly. If there is a cabinet with PVC plumbing, perhaps you can paint the interior of the cabinet and the plumbing black. I suppose you could also mount a shelf within the cabinet at the height of the bottom of the sink- so that you could only see the top of the shelf surface through the sink.

Put on the brakes with this fabricator and please find another one. The sink being undermount or top-mount has nothing to do with where the seam is placed. The only reason to opt for a top-mount sink is if your counter material is laminate, which typically requires a top-mount sink. If you are getting granite counters, you should be able to have an undermount sink, and the seam placement should not be a factor for whether the sink is undermounted or not. As mentioned above, the picture you show is a flush-mount sink. A top-mount sink will not be "what the edge of the sink looks like" in your OP photo. I hope you will be present at the template layout of your granite slab at the fabricator. You must insist on this.
