SWMBO, isn't happy with the typical double basin kitchen sink and wants to replace it with one large sink. (It's a resale, and the house came this way)...

I found a sink that should fit (30").

I climbed under the sink to see how it was attached and noticed the the lip of the sink (in the front) was resting on the cabinets to either side of the sink. The cabinets are slightly angled backwards...

It doesn't look like it will easily drop down.

We have granite countertops and backsplash, so simply lifting up the counter could be a major undertaking.

Anyone dealt with this in the past, or had someone do it for them without wrecking the current granite?

Thanks in advance!

With granite or quartz sinks are glued on. You may need a pro to do this one. I have seen them installed, never removed.

I've installed sinks before, including the sink in our NJ house(see pic below). In fact, I installed all of the cabinets, plumbing, backsplash, trim and electrical.

The counter tops however were cut and installed by a pro. While I would be comfortable simply replacing the current sink with a similar one, you are looking at a lot of trouble if it's not an exact fit. It's also a lot of work to cut and remove all the glue and sealer.

The sink does sit on the cabinet below. It should not slope backward, if it does, you'll need to shim it.

If your counter is split at the faucet, it's much easier to remove but a little harder to seal when re-installing. A single piece would be super easy to break. Your mileage may vary.

There is no real rocket science to it other than having the right sealer, in the right amount, applied in the right way. If it requires a recut of the counter, it'd be better just to have someone do the whole thing.

If your sink sits on the counter, then pry it up and put another one on there .

Anyone have any suggestions on who would do this type of job?

Counter guy? Plumber?

IMO if it’s not broke why replace it? Not only with basin fit problems you have plumbing problems going from 2 holes to one. But, I understand “ I want”. Problem?

You’ll be lucky to find plumber to deal with granite installed over the sink? You’re probably going to need both?

Not sure what you have but it does appear that you might need an undermount sink.

As an aside we have a farmer style sink(one big tub) and it drains poorly. This appears to be caused by fact that the sink is square(no rounded corners). We have to push the water down to the drain.

It sounds like the existing sink is an undermount sink and it is probably attached to the underside of the granite with wingnuts. You should be able to remove it, even if you need to cut away some of the cabinet wood to get it out. You can then install a new undermount sink. But, whatever you do, I would not try to lift up the granite countertop to remove the sink. Too much risk of it cracking. Good luck.

Yes, it's an undermount sink.

I figured I'd need to remove some of the cabinet)which would be hidden from view), but I'm nit sure I'd be able to mount the new sink.

I guess I'll call some counter people and see what they think...

If you can get the old sink out, you may want to use a new drop-in type sink (instead of an undermount), maybe a porcelain or cast iron type. It may be easier to install.

Mike Scott Plumbing handled ours, and they coordinated the trimming of the hole with the sink installation (two different individuals). We purchased the new sink from them - so I cannot speak to them installing a different sink. Done efficiently - we were very happy with the results!

I'm also looking to replace my sink. This is helpful info. Thanks

A few years ago, I worked with Stone Central in Wildwood for the replacement of my new sink. Did a great job with granite (had to cut slightly larger opening) and sink installation. I hired a separate plumber to undo/re-do plumbing under sink.

I have yet to figure out the fascination with the farm style sinks. If you do any hand washing of dishes, you really don't have any place to let them drain like you do with a double sink. You do have to chase around pieces of food to get them to down into the disposal. I personally think it is a fad that will eventually fade out. Just as colors of countertops, appliances and wood or painted finishes on cabinets come and go, I think the be tub sink will too.

Drop in is easiest route but seems your space is small under the counter top. https://www.havensmetal(dot)com/ (located in Orlando) can help you with your sink questions and/or can build you an awesome sink that can slide in between the counter top and cabinets. You can also have the sink designed to be exact size of the cabinet opening so if you have a 36" cabinet your sink can be designed to be the same. The sink can slide in if you went with an apron front sink.

Being a retired plumber, I would hire someone.
