The reveal should be up to you. Your choice, not theirs. I prefer a 1/2" reveal, but many folks prefer a flush or negative reveal. I don't like the idea of a " mystery area" that I cannot see if it's clean so that is the basis for my own preference. It really should be your choice.

Thanks chess I'm not big on the negative reveal for things to bump the stone. Hoping the 1/4" is fine.

What are your thoughts on the sink bowl diameter and how that will look when the stone is cut?

I think the sink looks great, but then again I spent $$$ more to get a sink that wasn't zero radius (my sink is soapstone). You said they are leaving a 1/4" reveal, but you don't say whether the reveal is positive or negative.

I'd want to know what the gauge is. 20 is unacceptable IMO. 18 slightly better. There are lots of 16 gauge (which is thicker) reasonably-priced sinks on the market. Look at Kraus sinks on Overstock and some other websites.

Your photo is upside-down. Your drain looks slightly offset - meaning not dead center - which is a good thing. The offset is toward the rear of the sink.

Thanks Sherri it will be 1/4 positive reveal. Can please share pic of your sink and counter how it looks cut? Why did you want no zero radius on sink?

M miller I don't know about the gauge...I'll ask hope not too late :/

omg I didn't notice the sink drain off center or pic upside down. guess that's fine. So the drain hole is set to the back? Hmm realizing I have no clue about sinks.

I didn't want zero radius because I didn't want to have to deal with the cleaning. I know a lot of folk think it's easy to clean, but having a slight radius is easier, and I am all about easy when it comes to cleaning. My last sink had a positive reveal, but this time I went with a flush install.

Drain at the back, and 18 gauge is good, imo. :)

Yes, the drain is offset to the back. That provides more of an expanse of sink floor to set down pans and roasters without covering the drain. There are sinks that have drains offset to the corner allowing even more uninterrupted sink floor. Sinks with offset corner drains are usually expensive and harder to find. Elkay makes one, and Blanco makes one in their Silgranit material. The drain offset to the rear like what you show is good too.

Sherri1058 - I agree many find 18 gauge to be good and are happy with it. I just like 16 better :)

The pictured sink has much too small a flange for a 1/4" positive reveal. That would only leave about 1/4" for silicone which is cutting it a bit too close for me. I recommend an 1/8" positive reveal, especially if you use that sink.

Most people like the reveal to match the radii on the sink. In this case that would mean no square corners.

Joseph Corlett, LLC I think that pic is a photoshopped one, if you look at the edges they are not even all around. Hopefully there is more to that sink than meets the eye. :-)

I don't like zero-radius sinks due to the cleaning issue. They are a PITA to keep clean.

I am a fabricator.

" it is better to have some bit of radius rather than zero radius sink corner" - This is correct. 90 degree inside corners create "stress risers" which are locations where cracks are likely to originate. For this reason even the various quartz manufacturers do not allow 90 degree inside corners. Our normal minimum is a 5/8" radius which also happens to be the minimum radius for CNC tooling designed to polish small inside corners.

For reveals our standard is 1/16" overhang or "negative reveal" on stainless steel sinks. This insures the the caulk joint between the stone and sink is never visible. Theoretically the flat sink flange should mate up tight to the underside of the countertop material but the back side of the countertop often is not perfectly flat and some sinks are also not perfectly flat across the flange (even though they should be.)

"For reveals our standard is 1/16" overhang or "negative reveal" on stainless steel sinks. This insures the the caulk joint between the stone and sink is never visible."

And you can never see the crud you should be cleaning. A small positive reveal allows you to see how clean your sink is.

Joe I was thinking that sink lip looked narrow too! I was thinking how the heck is that attached? I sent a text to my GC with that pic and he confirmed that's the sink they will be using and a popular choice. After looking at the pics I agree that would look weird for the counter to be cut square and the sink corners round. In these pics I think it still looks squarish ? I realize these have zero reveal but is this basically what I should expect? Joe your the sink/counter guy here ...thoughts on using that sink I pictured above?

Chess I don't think it's photoshopped but if you zoom in it looks like there is some light blue plastic wrap around edges ... oh maybe cuz sharp? Check out upper right corner it's wrinkled like plastic wrap.

oldryder thanks for chiming I was not aware of that about the stress risers. Don't want that! Also what you say about the flange mating up makes sense and the more surface area to adhere the better but the negative reveal makes the counter top/stone more susceptible to damage no? I've never had a negative reveal.

Thanks oldryder I will ask again about the reveal tomorrow.

oldryder, that is exactly the opposite from what my fabricator stated. This is the reveal that his shop does, as a standard. It is what most of his customers prefer, after seeing the flush and negative. It is very smooth, and very clean. As far as the edges of the sink being beaten up, that is nonsense. If that were the case, my drop-in sink I have now would have edges all dented to hell. And there's not a single ding or dent after 10 years.

That looks really nice chess. Oh geez I'm confused as which way to go. I guess I'll ask them what they typically do and why? They do a ton of this kind of work they should be able to tell me. I hope it's not too late.

Chess I just realized you posted aalmost exact thing yesterday about fabricator sink ... going to read thru the responses and look for more threads like it. Could be helpful!

oldryder is correct about engineered stone manufacturers specifying radius corners in cutouts. It's not a bad idea.

The pictured sink appears to have too small a flange to even be an undermount sink. It's probably a drop-in.

Sinks should be undermounted with straps. Either a Hercules Universal Sink Harness (Braxton Bragg) or a Sink Strap or two from Regent Stone Products. No other method turns a sink into a truss and allows a sink to be changed with one or two easily reached nuts instead of 8 inaccessible ones.

I've been strapping sinks with a positive reveal for many years and have yet to get a callback for any reason. No fallen sinks, no failed caulk, no dents, nothing. Not even a regret.

Please check to see where the sink is manufactured. "Free" sinks with granite work are usually $50 sinks imported from China and they can RUST!

I've seen a pallet full of imported sinks at a fabrication shop. They aren't comparable to a brand name sink.

Yeah I've decided to upgrade, just not sure what to yet.

I learned today that the one they were going to use for my install was an 18 gauge. I didn't recognize the name but they did say a fair amount of people bring in their own sinks as well .... customer preference. I decided to just go on my own and ordered a Kraus 16 gauge. Hope it's really nice quality. I had to basically ship it overnight cuz the guys need it. Any last minute opinions on a Kraus? Chess what are you looking at?

oh and I still don't have any more information on the reveal so I'm hoping to find that out when I drop off the sink.

Kraus has a lot of happy customers on this forum. It's a nice sink, you will see, and it comes with sink grid included; most companies charge extra for a sink grid.

Did you get the right size for your cabinet base? I'm assuming you were given direction on size (width).

You should clean your sink with Barkeepers Friend (in case you didn't already know this). Avoid harsh abrasive cleansers like Comet. Never use steel wool on your stainless steel sink.

How about saying this. I'm dropping this Knaus sink with such radius corners. I'd like it undermounted with straps. Either a Hercules Universal Sink Harness (Braxton Bragg) or a Sink Strap or two from Regent Stone Products. I want zero reveal flush mount.

As a fabricator I'm sure he can successfully do sink installs a number of ways Including the way you want it.

MaWizz, since I am really set on a 55/45 sink, it limits my options. I don't want anything smaller than I have now, and the Koehler that I love would require modifications to my cabinet to fit, so that's out. I will probably end up with this one, just wish I could actually see the darn thing somewhere. https://www.faucetdirect.com/elkay-eguh312010l-gourmet-elumina-stainless-steel-31-1-4-x-20-1-2-double-basin-kitchen-sink-with-left-primary/p688669?uid=688669

Or this one...actually I think this one I could do, it's only a fraction of an inch smaller than the one I have now.

https://www.lowes.com/pd/KOHLER-Undertone-20-12-in-x-31-in-Double-Basin-Stainless-Steel-Undermount-Residential-Kitchen-Sink/999935086

"...and the Koehler that I love would require modifications to my cabinet to fit, so that's out."

Which Kohler and how large is your cabinet, please?

The Koehler is in the link above. Model is K-3356-NA. My sink cabinet is a standard 36".

This is another sink that I like, and the price is great, but again, it appears to be too large for my cabinet. Joseph Corlett, LLC, have you made modifications to fit these larger sinks into standard (36") cabinets?

https://www.supply.com/responsive/pages/elkay-gourmet-undermount-steel-45-000-26-438-kitchen-sink-eluh3520r-lustertone/p22134

Either of those sinks will fit into a 36" sink base with little or no cabinet alterations. Your countertop fabricator will probably have to strap the sinks, not use insert style clips or other mechanical fastening methods, but that's not a big deal. Hercules Universal Sink Harness (Braxton Bragg) or Sink Strap (Regent Stone Products).

Joseph Corlett, LLC, really? Dang. Is using straps a good safe method? Not meaning to offend, just never heard of that before (but obviously I don't install sinks so what do I know? ). Maybe I will email my fabricator and see if that is something he is agreeable to.

"Dang. Is using straps a good safe method?"

It's the best method. It turns your sink into a truss, making the weakest area into the strongest. It is not disapproved by any top manufacturer, unlike insert style fasteners. If your sink ever has to be changed it's one or two easily accessed reusable bolts instead of 8 inaccessible unusable ones. Shall I go on?

M Miller yes I am downsizing from roughly a 40/41" sink base to a 33". The larger was quite a waste of space I didn't use for much. This way I'm gaining a drawer bank to have a better finished end next to dishwasher, more useable drawers and better balance With cabinetry. Anyway I ordered a Kraus 30" for a 33" cabinet show below

Joseph Corlett, LLC, ha! No sir, no need to go on. Thank you for the information! :-)

MaWizz, that is a nice sink. I just can't get comfortable with the one bowl, otherwise that would certainly work for me.

Update: Sink was delivered and it's beautiful! Very heavy duty! So much different looking and feeling than the fabricator sink! I didn't even lift it out of the box just checked for damage. Came nicely packaged with all the accessories pictured above.

I dropped the sink off to the fabricators and got better clarification on the reveal. The owner who was there before had told me 1/4" positive reveal. My GC said when you bring your sink in talk to the guys who will actually be doing the cutting not the owner. So the guys bring the sink in for me and place on a shelf with a dozen other Kraus sinks on deck! Good to know! Anyway I ask about how the reveal would be done and told them I saw it came with a template. They said yes the Kraus template is for flush but we prefer 1/16" negative reveal even better. Said flush -1/16" little overhang is best. Basically for every reason oldryder said! They said that is their standard. No water on lip, no visible caulk, no yucky mold to see or yellowed cracked caulk/glue, better adhesive for full surface of flange etc. sounds good to me! I had basically flush on sink in my last house and it was fine but I often paper towel dried the edges after using it because I was warned of mold. Joe some of those sinks you show with the mold are disgusting! Pigs! Your repairs are incredible by the way. Last couple you posted look amazing and even the watermelon left on counter repair!

Thanks for everyone's input on sink quality and install recommendations!! I feel like I was able to make a much more informed decision and really happy I did not just go with the fabricator/free sink!

Btw my kids think it's too big and overkill! Haha Never! :D But the one that was just torn out looks like this. I forgot they were too young to remember our last deep one.

Joseph Corlett, LLC, just heard back from my fabricator, and he said my selected sink (the Kohler I mentioned above) would not fit. They use clips, and he said there was not enough room to mount the sink. Very disappointed. :-(

The sink will fit just fine. Make him strap it, please. Offer him an extra hundred bucks.

It's not an option. I have to go with what he says unfortunately. He said the clips they use are the only method they have used that have never failed, so not much I can do about that. I will just have to find a smaller sink.

And be disappointed every time you see your sink? Unthinkable.

I'm not changing fabricators over a sink. :-) I will find something else.
