30” sink in a 21” cabinet?

5 years ago

I want to put an approximate 30” sink in a 21” cabinet. I know I know. This sounds silly but there is 25” of dead space next to the sink cabinet (dead space is because there is a corner there-cabinets form an L). Can the dead space cabinet be cut into to accommodate a larger sink? What are my options?? Just wondering if this is even possible before asking for bids.

More info: These are new cabinets.. just delivered, not yet installed. We are building our own home with a General Contractor (not a real “builder”) We are doing much of the work ourselves.. so I’ve been having to learn as I go. Unfortunately I didn’t catch this on the plans. (So focused on kitchen and bathroom cabinets I didn’t inspect the laundry room cabinet plans very well.) A large sink is absolutely needed because I plan to bathe my dogs in this sink. Attaching the dimension diagram.

So it is really a 28 inch cabinet? With 3 inches of filler on the right side.

21 (and 7/8) is the depth.

What is the front of the dead space?

If you are doing a lot yourself, are you installing the cabs yourself? Just trying to understand what the quote is for....

You can usually do a 30 inch sink in a 28 cab. My other question would be what is the depth of this sink. Presumably a kitchen sink so expecting a 24 inch deep cab?

You need exact inner and outer dimensions of the sink and pics of cab construction with measurements to really tell.

33" sink in a 27" cabinet. Not a problem.

Joseph Corlett - Just curious, what were the door, decorative panel, and filler panel attached to with all that material cut away?

Megz, I believe David is correct. According to your layout drawing, your cabinet is actually a 28" cabinet. I would double check with whomever drew up your plan. You may be worrying over nothing since a 30" sink can definitely fit in a 28" cabinet without a problem. We did this ourselves, it just took a little modification on the sides of the cabinet box.

Oh, and definitely be sure to find the correct depth of sink (front to back depth). The 21" cabinet depth can't really be fudged to accommodate a too large sink!

Thanks everyone! Looks like the cabinet depth is 24”. The sink I’m considering is 9” deep. Next to the dead space is a pullout trash can (and then the washer/dryer counter.) Here is another view of our plans.. we are not hanging ourselves.. our finish carpenter will be doing that.

While I was researching our kitchen sink and cabinets I’d read that the sink should be a few inches smaller than the cabinet in order to have something to under-mount to. Looks like there are workarounds! Thank you all again :) This has been very helpful!

Typically the faucet and center of the sink is centered on the window.

Megz, I see from your arial view drawing that it does appear that your cabinets are 24" deep. In that case, I'm confused by your first layout drawing. According to the measurement that I've highlighted under the cabinet layout, your sink is 28". I'm not sure what is supposed to be 21 7/8" indicated on the front of the cabinet?

Instead of cabinet #2 having drawers, you can put a rev-a-shelf in there to have full access to that blind corner. I have used these and they're excellent. https://rev-a-shelf.com/catalogsearch/result/?cat=41&q=Optimizer

@partim thanks for the suggestion but cabinets are already built. I’ll have some access to that blind corner because the trash cans (actually a trash small trash plus a large dog food bin) are both removable. I’m mainly using the pullout to store my dog food and have considered using that blind corner for storing seasonal bins or something.. just not sure how easily accessible it will be

There is still 2/3 of the original center cabinet left; that's plenty. Don't forget, once the sink is properly reaffixed, it supports the top.

Sink manufacturers want to provide access to their junk and leaking clips for fat plumber hands, hence their space requirements. When sinks are strapped, no access is required or necessary because the sink is secured by an easily accessed bottom turnbuckle.
