Undermount sink

[crokett]

I have a stainless sink that AFIK was designed to be a drop in. With the correct clips can I install it as an undermount when I pour that section of the new counter?

[frumper64]

I think so

I can't imagine why that wouldn't work if you can find the right clips to hold it in place. The self-rimming part ought to provide a nice reasonably flat surface to run a bead of caulk to prevent any leakage where it meets the bottom of the counter.

Thx. I had to open my big mouth when LOML saw a pic and asked if I could do the undermount. I can but it will be a lot harder.

Drop in sinks either self rim, which means the underside of the edge of the sink just gets caulk or plumbers putty, or the kind that has a hooked strip under the edge that a clip attaches to and a leg on the clip pushes up to the underside of the countertop when turned in. I doubt there is a way or a clip available to utilize that method.

There may be hardware to do that, but drop in sinks aren't designed to have absolutely flat top surfaces. But most have enough flat surface to use epoxy as a glue. Using the top flat surface as a glue surface will put the holes fairly close to the counter top cutout edge. Check your faucet for its layout on the sink before going too far.

Cabinetman,

I plan to do a mockup this weekend of the whole thing. I just wanted to know if it was even possible. I am not doing the pour until next weekend. I will not depend on glue to hold the sink up. I would do mechanical fastners and a sealant. The bolts for the fasteners will be installed as part of the pour.

I say be adventurous- do your own concrete undermount sink. I'm playing around with doing that myself. I actually am thinking of doing a farmhouse style sink. You can cast seperate panels and epoxy them together, or do it as a single cast.

Otherwise, just ditch your current sink and get one specifically designed for an undermount application.

You could stick the sink in place, undermount, with silicone caulk and then also screw a wooden brace on at least two sides to the sub-countertop plywood (or whatever is under the concrete). If there is nothing under the concrete, you could put concrete screws into it but near an edge that is kind of dicey. You could also embed a wooden piece into the concrete (make it tapered so it won't come out) and then screw the sink to that.

ditto

you can actually get the molds from cheng's website. I think i'm going to do this for my bathroom....in fact, i'm definitely going to try it.
