I picked the Shaw but I think the Franke looks just as nice. Our marble installer cracked the sink during the install. This whole sad saga is described in other threads. But the point here is that Rohl replaced it, even though I told them exactly what happened. They still called it a "thermal crack" and replaced it. I was totally surprised at this decision on Rohl's part. Another little factotum about the Shaw's sink (the 30 --this might not apply to you if you get the 36) -- the sink's drain has a left hand offset. At least most of them do. About one or two in ten have a right hand offset and these are sent out "randomly." Don't ask me how I know. The sink now installed in our kitchen is not the second, but the third sink that has been sent to us. Now, the downside is that the Shaw sinks do vary a bit and so the new sink did not exactly match the first sink, the one upon which the marble was templated. I'm thrilled that we -- I should say DH, who has pulled many a miracle in this kitchen -- was able to get the old one out and the new one in without perturbing cabinets or marble that were now firmly in place. The margins around the sink are not exactly even. I've decided it will just be a reminder about the hubris of desiring perfection and have moved on. Just a couple of things to know about Rohl and Shaw's sinks, the good and the, well, idiosyncratic.

i have the rohl 30" and love it. the drain is off to the right on ours. hth

@Ev Mann is the fire brick essentially like pumice? I have used pumice for cleaning hard water mineral deposits from a porcelain toilet. I also have a fireclay sink (Shaw's)- installed ~6 months ago. I repeatedly told the plumber about the need not to overtighten. I was on a work call while he installed the disposal so not sure how that went. Even if I were to have watched him, I'm not sure what I would be able to tell re: tightening but he did say he didn't after the fact. Regardless, I thought everything would be ok because we are 6 months in. But, alas, I noticed our first relatively long (e.g., 1 1/2") fine line crack coming from the drain. I'm interested in trying the firebrick but is it essentially just buffing it down to below the scratch? I just felt the scratch. I can feel it slightly under my fingernail. (quick edit, just found this article... https://homesteady.com/12265081/how-to-fix-scratches-in-a-rohl-fireclay-sink. Looks like pumice could serve the same purpose as the firebrick and be a bit easier to purchase/use?). I'll try it later and let you all know. New edit: Spoke with Rohl - they are saying 100% that this is due to over tightening and that the crack will get worse.... Uugh.

The 12727 has deck holes that are a 4" apart which means only a very small faucet mounting possibility. The 12700 has an 8" spread (more normal). The 12700 has a 3-5/8" drain; the 12787 has a 2-1/4" drain. The 12787 is designed to be installed on brackets and only comes in white. Installed they will not look exactly the same due to the faucet restrictions and mounting styles. If you plan to mount the utility sink on a cabinet vs brackets I would call Kohler and ask if that's possible. The notes specify installation instructions.
