Can you install a 30.5" (28" inside) sink in a 30" IKEA cabinet?

I want to install a 30.5 under-mount sink in a 30" IKEA sink base. The measurements of the sink without the flange is 28". The cabinet sides measure 3/4". I know you need to use mounting clips and the installation pictures make it look like you need several inches on either side, but I was wondering if there was another way.

Commenting on my own question....I did read another post after the fact where it was stated that this is not a good idea. The sink I've chosen is a qualtiy sink and 7.5" deep. I need it to be shallow. My only other option is the Kohler Bakersfield which is a drop in sink. That's problematic as well because they say that it will fit a 30" cabinet but the cutout is 29.5 inches and Kholer won't answer my questions about whether or not it will fit in a cabinet with 3/4" walls. I don't want to go with a smaller sink but I may have to. Not happy : (.

Use a HUSH or other sink strap of some sort instead of clips and you'll be fine and have a stronger install, too.

Steve, I'm in the UK so am unfamiliar with Home Depot items. However, sinks in that price range over here I'd imagine would be similar, same gauge of s/steel etc and friends who have them hate stainless. Our sink in our old kitchen when we bought this house was a DIY store special I think ( everything the owners did was cheap and to enable a sale). It was the bane of my life. Hated it with a passion and vowed never to have stainless. Well, then I found this forum! I now have a kohler stages 45 sink and its 16g and obviously was £££ but I love it. Cleans up a dream and is very quiet too. It is a massive part of our kitchen functionality. So that was the only reason I said to get the best sink you can afford nothing specific about that sink ( though H.D do it in 16g and it is over $300 the one you linked is 18g which is still good but not the top) you are right that it is possible to remove a sink that is under-mounted and replace it especially if it has been installed with a cradle system like HUSH, undo the cradle, loosen the silicon round the sink and it will come free. however, if the sink is as big as the cabinet or almost and the cabinets have been messed with to enable it to fit it will not be possible to get that sink out of there without breaking into that cabinet that's really why I said originally, try and go for the best sink now rather than come unstuck.

I too want to give a shout out to Kimmy for her detailed instructions. I just installed a whitehaven following them. I will add this the curve for the cutout is 4" so a 4" hole saw on your drill will give you the perfect cut then you can use your circular saw up to the holes on the sides and bottom. I don't own a jig saw so I used the same hole saw that I got to cut my butcher block with a reveal (also 4" obviously). In addition to Kimmy I want to thank Joseph for recommending Pete's sink mount. I realize most on this thread have already installed using Kohler's instructions but Pete's sink mount makes getting everything in and level super easy and you can adjust up or down with the sink in place unlike Kohler's 2x4 method. This is an FYI for anybody that comes upon this thread later. Steve - Ikea sells a kit to attach a door to a drawer that has a template to drill the holes. I realize you don't need the hardware but it might be worth it for the template. https://www.ikea.com/us/en/catalog/products/00280755/

Installing Undermount Sink -- 30" ok for 30" Cabinet?
Q
Comments (1)
"Is it possible to install a 30" stainless steel double bowl undermount sink within my cabinet?" Yes, however, I'd suggest a low divide sink. I'm constantly replacing perfectly fine double bowl sinks. Nobody wants them anymore. You may have to recess the top of the cabinet sides to accommodate the sink flange thickness. The sink flange and cabinet tops must be flush. "For the record i'd still be using undermount clips/clamps along the front and backside of the sink to secure it to the bottom of the quartz countertop, just not along the left and right side which are sandwiched between the cabinet ledge and the underside of the countertop." Abandon this idea, please. Install a Hercules Universal Sink Harness (Braxton Bragg) or Sink Strap or two (Regent Stone Products) to the cabinet sides, then place your sink. Run a bead of silicone around the flange, set the stone, place a bar clamp through a 2x4 spanning the cut-out and drain hole, tighten the clamp and adjust the sink. When the reveals are perfect and you've got lots of nice silicone squeeze-out, tighten the harness/strap(s) and pull the clamp.

I wonder how you can get a plumber to use a HUSH if he's not familiar with it? Put in writing the specifications of the work required during the bid process and have a contract. You are the consumer and are paying for the service you want done, not what the contractor feels like doing. To make yourself more comfortable, print off documentation/specs and have an itemized listing of the required work that you hand to the contractor that you are asking for estimates. If they refuse to perform the work you require, or aren't willing to research a valid process, practice, or product, you don't want to hire them. I've worked with contractors my entire life and they have a difficult time arguing with knowledge and facts.

Writersblock, thanks for your response. Would your solution limit my ability to replace the sink at a later date if I needed to?

No, quite the reverse. If you have a sink replaced, it's almost always done with a harness. Joe should be around soon to explain, or you can search for posts by Joe Corlett to see examples.

That sink will fit easily if you use the Hercules Universal Sink Harness (Braxton Bragg). Disregard the manufacturer supplied clips, please.

@writersblock (9b/10a) How do you account for the extra 0.5 inch of the flange for the install with the strap, and still be able to remove it later? Do they just cut the plywood back 1/2" on each side of the cabinet (leaving only 1/4" sitting on the cabinet wall) to allow for the flange to slide into place and be removed at a later date?

You unzip the top of the cabinet sides. Not a big deal.

When strapped in place, the sink does the structural work the top of the cabinet sides did.
