I’m not sure I’ve ever looked at the back of my sink cabinet. Put your stuff in the cabinet and forget it.

Mine look just like that. Never thought anything about it. I built a shelf to put on that side in front of everything, so I could put more bottles of stuff in there. I also put vinyl tile on the bottom shelf, to keep things looking a bit nicer and easier to clean.

There is always a better way of doing it if you take your time and put your mind to it. They cut the back just to get it in... They could at least make a nice straight square cut so it would look a little better... instead they went all over the place.

The cabinet should be pre-drilled for each shut-off valve and a drain pipe, and there're chrome trim pieces that go around the valve's pipe and drain pipe against the cabinet to make a nice clean finish. If drain pipe comes into the cabinet on the angle like in your case it should be done like this to give you an idea, this is how I do it.

You could get a piece of paneling or laminate to cover the crude job they did. I'd remove the disposal and valve handles for access and make a cardboard template as a cutting guide.

Yeh, it looks crappy & the installer could have done a much, much neater job of it.

And, you could do as HU....1711 suggests. Cut a piece of panel oversized and make neat holes for the water connection and a neat squared cut just big enough for the drain. Use some construction adhesive to glue the new panel over the existing along with some pin nails to hold it in place while the adhesive cures.

But the reality is that you'll never see it. Even with it empty, you basically have to stand on your head to see it. And that's before it gets loaded down with stuff. The only time that I see the back of my equally, crappily cut out sink cabinet is when I clean under there and try to organize too much stuff. Dreadful job that happens once every 3 or 4 years, at most. :-)

As others have said, this is something that you will cease seeing as soon as you have moved back into the kitchen although obviously it shows work done by people who have little professional pride.

I just finished a gut remodel and obviously there were some issues but I made deliberate choices in terms of what I redo-s or fixes I would ask for. My standard was if it impacted functionality in any way or if it was something that I would actually see. Otherwise I would let it go - my GC was extremely accommodating and did stuff for me that was helpful in many ways (like helping move furniture or helping me with handyman type of stuff that wasn't contractually required) as were the tradespeople he hired and I think my attitude had a lot to do with it. Once he even mentioned that he didn't want me to think that I was being taken advantage of because I was a "nice person" :-).

It's probably too late at this point but for other people who happen upon this thread, I had my sink cabinet clad in formica to help with keeping it clean and also installed a roll out so that items stored under the sink didn't fall into the Black Hole of Calcutta. :-).

True nobody will see it and most likely nobody will ever look under it when it's filled with items... But I can see it while doing the install and people will see it when I deliver my work... Not to mention I can probably measure and transfer the measurements onto the cabinet faster than do that cut, you can tell they been going back and forth cutting more and more to make it fit :-).

Well, you might not be able to see it with the doors closed, but that sloppy work is like the entrance to the Holland tunnel to any insect or mouse. All those openings should be sealed up especially the area behind the cabinet (huge holes in drywall). It’s not just about aesthetics.

If pests are behind the cabinets, you have more issues about them getting inside the house than you do anything else. They will still get inside the cabinets. They don’t need bit 1/8” inch. Specious argument.

Except for the pests to get into the cabinet means that they are already in the house.

Not unusual

@Drsaj Soon Houzz will add a new category "Hacked Up Jobs" or better yet "How Not To Do Things" so save your picture, you can posted there. :-)

Lucky you. Mine doesn't have a back.

LOL GN. I'm not going waste my time worrying about a small cut-out under my sink.

:-) Who said anything about someone should be worried about this...It's not about a hole under the sink, its all about taking pride in your work, your quality workmanship someone hired you to do and most importantly respecting homeowners property for which they paid their hard earned money.

Watch and Learn How it's done... If you see it done any other way, it's cutting corners or installer simply don't know or don't care.

If I didn’t have horrible leaking incidents under sink in my previous place, I’d probably have an easier time accepting this. Thanks everyone!

I had plumber do the same under brand new bathroom vanity. Ended up it wasn't necessary which made me even more mad. I have looked and looked for a way to repair it.

Kathy, do you have a picture? If yes, please upload it will be easier to suggest a fix.

Plumbers did a number on my cabinet under the kitchen sink. Any suggestions on how to patch this up? Before they started, there was no hole and it was clean and white.

Cut to size the entire lower piece or install in 2 pieces and do the same thing for the back. You can use laminated material or use plywood smooth on one side and paint it.

It looks like the back and side wall is sheetrock if it is, use drywall and glue it over it.

Thank you!
