Right now the prep sink cabinet is 28", and going to 33" would be really tight.

Thanks, live wire, for the reassurance. This is all new to me, and I'm nervous about being misinformed. I don't think my fabricator is using a CNC, apparently he prefers to trace? My interior designer(who recommended him) really likes him, uses him all the time and has been happy with his work. Is it a mistake not going with someone who uses a CNC?

If the fabricator has the sink in his possession before beginning fabrication, there is no excuse for not having a perfect reveal, positive or negative, and a guaranteed sink installation. A good fabricator does not need a CNC machine for a great job, it just takes him longer.

Thanks Joseph, I think he is worried about lining up the top mount faucet hole with the faucet hole on the counter in order to make it undermount. Unfortunately blanco recommends using the undermount DFX file to install this sink as undermount, which won't have the faucet hole... I'm really not sure what to do.

The fabricator saw the specs and now wants to add a $500 surcharge. I am confused because blanco and my plumber say it's common to undermount this sink?

I'd want to be really, really sure a 22 inch pan will fit into a 22 inch sink.

That is a good point!! The pans are actually 21 3/4.

I've just found that blanco USA (I'm in canada) has the diamond u 1 in metallic gray.. I'm sure shipping would be cheaper that $500 ;)

For my second reno I had to buy the sink in advance and have it sent to the fabricator. It was a Julien and, for some reason, it was off square. The fabricator rejected it and the sink had to be replaced. As a result, they gave me a slight negative reveal on the sink without asking and I wasn't thrilled with that.

So I'd just be sure, especially with a surcharge (which I'd try to negotiate) that the way the undermount will be done is discussed. If you don't understand what I'm talking about it can be easily explained.

But you want them to have the sink ahead.

I agree, rococogirl, if I'm paying that much for a sink, I definitely want to be happy with the reveal. I'm hoping the diamond from the US will work out though!

I am very skeptical that a sink was out of square. This sounds like some fabricator B.S.

I gave my sink to my fabricator (it was a Blanco) and they didn't even use it. Cut the hole based on a different Blanco sink size.

@jcollins -- Well said. As it happened, I wasn't able to use accessories for the sink due to the reveal since that made the cut out was a bit too small for. I did a work around.

But if I'm paying an upcharge, I'd be sure they were shown exactly what I want -- I like an actual meeting for that with the KD. I had that when my counter tops went in in our house. That involved stainless counters being scribed around an upmounted Rohl farm sink in a pulled out cabinet. It was complicated and I was able to show the fabricator exactly what I wanted. He was genius, which helped a lot.

@Joseph Corlett -- I'm an interior designer. This was my second kitchen and I had drawn the plans myself. I didn't believe it either at first, and I didn't like the stone & tile sub at all. But the fabricator provided a photo and it was absolutely true. It actually delayed the job for several weeks. Julien was very good about it and very helpful in facilitating the exchange.

In retrospect, I should have gone up to the fabricators after the new sink arrived to discuss it. But my husband was ill and I was going to hospitals. Fabricators want to do things their way. I get that and get why. I just didn't care for the negative reveal and it ruined the flexibility of the sink. If I'd had a better sub it might not have happened. But he didn't buy the sink so it was the old FU.

I like to have a negative reveal , so it hides the silicone line . Here is a Blanco Diamond U

To address your worry of the precis corners...we have a large precis in anthracite and the corners are still rounded enough that it's easy to clean. It matches very well w/ the super single we have. I am curious, if washing your 22" pans is so important, why wouldn't you consider a larger single bowl sink instead of the 1 3/4 (that one has a lower divide right- so you could also wash the larger pans in there....).

For me, negative reveal looks very good. And is fine for any sink without working parts. But with a cutting board or colander or anything that needs to slide across it isn't the right reveal. But very nice with sink shown in eurocerobs post.

peppermintleaf - thank you, that is good to know about the précis! Hubby and I have been back and forth about the large single bowl vs the 1 3/4. Because of a complicated layout, we have designed our kitchen with two ranges in two different work stations(we can't put them side by side without losing prep space or the prep sink). One is geared more for baking, and one is geared more for cooking. Hubby and I are often working in the kitchen at the same time, and I often am baking. The larger sink is near the cooking station, and beside the dishwasher. We realized that it is quite common for one of us to be doing the dishes while the other needs to drain boiling water or wash their hands while cooking, so we wanted the option of having an extra bowl for that purpose. The prep sink is far enough away that it would be a hassle to walk across the kitchen with a pot of boiling water. However, I usually hand wash most of my baking bowls and pans, so a large-ish single in the baking station would be very useful! So long story short, we have spent a long time considering it, but don't think a super single would be the right choice for the way we use the kitchen. Thanks for suggesting it though! Had I not been reading this forum, I don't think I would have even considered a single bowl!

If the prep sink is "all the way across" from where you need to drain pasta, then it's located incorrectly! I suggest you post a layout so that the function can be improved before you set awkward work patterns into stone.

The large sink has prep space beside it for cooking, as well as space on the other side for clean up. I may have incorrectly termed my second sink as a "prep" but it is in the baking section, where I would never drain pasta.

I understand what you are saying, but wanted to ask if you actually find yourself soaking your sheet pans much? I ask because after I started using baking parchment and Silpats, I end up just sort of rinsing them. But maybe you use yours differently. I just like to go back and question my assumptions when I find myself in this situation!

That is a smart thing to do, Lori! I do use parchment paper, so I don't usually have to soak them.. Right now I'm using a double sink with 14.5" bowls, and when I wash them In a hurry(my usual!), it's easy to get water everywhere. But I'm sure that even the 19 3/4 précis would be a huge improvement. I just get frustrated that the précis is actually more money than the bigger sink I want!

I have the Vision undermount sink as my main sink. The bottom measures about 19 1/2 x 13".

Wow, I had no idea! Thanks so much for letting me know! I wonder what the précis u 1 measures?

Now that I know that the 22" won't fit my pans at the bottom, I'm just going to get the précis. Thanks so much for all your help!!!

I think you should thank the fabricator . By asking you to give him the sink , you definitely had to take a decision . Sometimes it is all about that .
