Is that interior or overall width?

If overall, then it should. When I was sink shopping, my KD told me any sink w/an overall width of at least 1/2" less than the width of the cabinet would work. So, if the 32" is the overall width, then you should be fine. Our sink is 35-1/8" overall width and it fit in a 36" sink cabinet with no problems. I have 1/2" cabinet walls.

If interior, then you might have to scribe the sink cabinet... Some here have done that, so if needed, post a question about it.

Anyone else?
thanks

That is what I am doing and I think it will be fine.

Which silgranite sink are you looking at? I am probably going with the cascade super single which is 32 in. in a 33 in. base. According to the spec sheet it should be fine.

I fell in love with buehl's sink on previous posts but I don't have the space for it.

Here is a link that might be useful: silgranite cascade super single

any pictures of how this looks when it is done? I am looking at an Elkay 30-1/2 in undermount stainless steel, single basin sink for a 33" cabinet base. Manufacturer says you need a 36" cabinet.

@kcholmen -- Do you mean the under side? If so, do these help?

Edited to add:

This is an old picture. It has since been "strapped" like Joseph mentioned below. It "fell" due to poor installation,. After reading Joseph's many posts about strapping, I had it strapped when we fixed it.

(The sink width was fine, no issues with that, it was the actual installation that was poorly done.)

"Manufacturer says you need a 36" cabinet."

Manufacturer is wrong. A 33" sink undermounts into a 33" cabinet, a 36" sink into a 36" cabinet, etc. when the sink is strapped, not clipped with the leaky clips provided by the manufacturer. I've done this thousands of times.

Do you mean to set sink on top of cabinet frame and granite on top that? or to notch out a little bit? my 23” sink wont fit in my kraftmaid 24” base because it is 22.5” , left to right, interior installer wants to notch it out some

Relieve the cabinet sides an inch or so. Install a sink strap system, set the sink in place, install the top, then silicone and install the sink.

@Joseph Corlett, LLC I have a 33" cabinet. I found a 32" Blanco Silgranit sink (Diamond) I like and the Blanco spec sheets seen on Home Depot site say need 36" cab. On Blanco's website sink chooser when you click what size cabinet you have I select 33" and I get no available double bowl options from Blanco so seems like the theory of a 33" sink will fit a 33" cab might not always be true w some manufacturers? The cut out specs say 29.86 wide - That sure SEEMS like it would fit unless this brand requires much more width space for installation. I get Depot's site might not always have accurate info but even Blanco said they had nothing for my 33" cabs. ANyinsight w this brand? Thanks!

Blanco is wrong. The sink undermounts in a 33" cabinet. Done it hundreds of times.

@Joseph Corlett, LLC Joe, I managed to convince our contractor to strap the sink into our new cabinet, although he thinks he can still convince me to attach the sink to the plywood. It is a Blanco Precis undermount 32" single bowl sink. I ordered two Sinkit Sink Strap kits already. Today during installation of the cabinets, the installers realized that we would have to go with a 33" cabinet rather than a 36" because of centering the sink under a window. Now the contractor is insisting he will have to attach to the plywood. Last year in this discussion about a similar situation to mine, you posted to " Relieve the cabinet sides an inch or so. Install a sink strap system, set the sink in place, install the top, then silicone and install the sink." What does "relieving the sides" mean, and how would the Sinkit clips attach to the side of the cabinet? Also, because of the center drain and garbage disposal, would it be better to use two straps front to back around the drain? It's so hard working with an installer who has not even heard of strapping. We had an undermount sink that was permanently attached before and I never want to have that again.

This picture answers your questions. The sink flange sits over the top of the cabinet side; the cabinet front will be reinstalled when the apron front sink is in place.

Plywood cannot push sinks up as straps can. Don't allow it please.

Thanks so much @Joseph Corlett, LLC, and for replying so quickly too. The Blanco sink we wanted was a regular one bowl sink, not an apron front. Not sure if this would change anything. The picture you posted was great. So when installing a new sink, we would remove the front of the cabinet and the sink would slide out, correct? I found out about sink straps from your posts here after we started the remodel. If I had known before, I would have picked a contractor willing to install with straps. We are a big family and a large sink is important to us. He cannot understand how straps attached to the cabinet are strong enough to hold up the sink. He is not willing to cut into the new cabinet as he says it would weaken the cabinet (see triangular pieces in corners that would have to be removed in picture below). It would also void the warranty, and he has supplied the pre-fab cabinets, so either I find someone else who is willing to, or I get a drop in sink to avoid attaching to the plywood, which is the way I'm leaning now. Do you know of anyone with your expertise with strap installation in Los Angeles? I hope there's a way to install the top mount sink into the quartz where we can do an undermount with straps in the future.

Also a side question. We had mold damage which started the kitchen demo. Mold was around the dishwasher cabinetry (dishwasher leak), and also on the plywood subdeck around the sink (we think from weak caulking and holes in grout between granite tiles on countertop). Is there anything that can be done to protect the cabinets from dishwasher leaks? By the time you realize the dishwasher is leaking, the damage is already done. Thank you so much.

This the sink we had planned to install:

Blanco Precis - Undermount

The top mount we will probably install:

Diamond Blanco Sink - Top Mount

" So when installing a new sink, we would remove the front of the cabinet and the sink would slide out, correct? "

Yes.

"He is not willing to cut into the new cabinet as he says it would weaken the cabinet (see triangular pieces in corners that would have to be removed in picture below)."

The cabinet isn't weakened. The corner blocks can be removed; they're mostly for shipping.

Don't get a top mount sink please. And get the Elkay instead of the Blanco; it's a much finer composite.

"Is there anything that can be done to protect the cabinets from dishwasher leaks?"

A proper sink and appliance installation is all that's necessary.

@Joseph Corlett, LLC Joe, it turns out we can get a 30" wide Blanco sink for the 33" cabinet we ended up having to keep. The contractor won't have to cut the cabinet for the original 32" sink we had, so I think I can convince him to strap the sink with the Sinkit Kits I bought. It will have a garbage disposal attached to it. Should the straps be installed from side to side, or front to back of the cabinet?

Thank you so much for your help. I called around to so many places to find someone to strap the sink if the contractor refuses and no one had even heard of it!

Here's a link to the sink:

Precis 30" Blanco Sink

You're contractor never had to cut the 33" cabinet to install the 32" sink. I will guarantee this; I've done it hundreds of times. Keep the 32" please.

Install the straps side to side, but either way will work. You want the rear strap far forward enough that it doesn't slip off the rear of the sink. Make it bend around the disposal flange if necessary please.
