Replace bathroom sink on granite countertop

Kris
by Kris
I am buying a new home. The guest bathroom has new granite countertops but I don't care for the self-rimming sink or faucet. I want to replace. If I take the sink out, however, I will have a large cutout in the granite. Can I put a larger above counter sink on granite that covers cutout? Will that work with drain?

    As long as sink fits opening and drain lines up it should work I would think.. Just be sure and measure opening carefully and then measure new sinks insert area if any or that it has enough solid countertop to sit on and covers hole completely-- then measure where drain is in opening on your sink cut out (from wall--then measure where drain on new sink sits,) make sure will work before buying. Note here Hubby says you can get couplings cheaply and easily to move drain if needed to work w/ new sink if doesn't line up perfectly as it is now.. He said as long as a top mount sink like picture will cover hole in granite and have plenty to sit on go for it. Good luck and Post pics when done :)

      @Cynthia E And don't forget to seal it tightly for no leaks. You should be good to go.

    Great answer from @Cynthia E ... plumbing likely wouldn't be in issue, longer supply lines if needed for the faucet, maybe a bend and an tailpiece extension for the drain. As Cynthia said do your research up front ... you can find accurate installation specifications for almost any sink online. Obviously the new sink would need to slip into the hole and overlap the cutout - if you find a sink that is bigger than your cutout someone experienced with cutting granite should be able to expand the opening. Good luck @Kris

    I did that, and I just watched the drain holes, and my husband put in new lines. You will need to find a granite fabricator if the sink is too large. Cutting granite properly takes certain saws.

    I was planning on the new sink being an "above the counter" type so there would be no need to cut granite to drop in a sink. Thanks all!

      @Designing Home INc. The first picture is the one I want to replace. It is indeed on a granite countertop. The second picture is the sink I am considering to purchase to replace the self rimming one in the granite.

    Hi Kris. as I see the picture counter top is not granite and it's laminate top but still you can do what you planing even easier

      @Designing Home INc. Go back and reread what she wrote. The house she moved into is the one she wants to replace the sink ON THE GRANITE COUNTER TOP. The second picture BELOW the one she now has is the type of SINK she wishes to USE on TOP of the granite counter top. That is her dilemma.

    Depending on the size and shape of your new sink, you may have to have the granite cut. Contact a reputable granite installer to do this as it requires special tools and skills. I love the square "trough" sink you've chosen. It will look great in your bathroom.

    I don't see any reason you couldn't use the sink you have picked out, as long as the sink is large and can "sit" on the granite. You might have to use an extension on the water lines or purchase longer ones, but they sell flexible water lines. We had to use them when we put in vessel sinks on our bathrooms. Love your sink choice.
