Cutting Butcher Block for an Undermount Sink

Cutting Butcher Block for an Undermount Sink

One of my goals for 2015 is to finish sharing our kitchen that we re-did in 2013! It’s been over a year and a half since we revamped our kitchen. As most of you know, our kitchen wasn’t in bad shape, it just wasn’t what we liked. We kept the guts of the kitchen; the cabinets and appliances and removed the formica countertops, installed a new deep sink and amazing Moen MotionSence faucet, and tiled the back splash. We also added some extra cabinet space.

Today, we are sharing a few of the tips and tricks we found useful when we installed our butcher block countertops. We also created a quick video to show the process of cutting out the hole for the sink. Talk about pressure! One mess up and it could have been very costly!

Jon laid out the countertops and then used the sink template that came with our Moen sink and traced the template exactly where we wanted our sink cut.  Make sure you account for your front edge and enough space to mount the faucet. The template will not show you this. You’ll also want to make sure you sink is centered with the cabinet under neath so it won’t interfere with the cabinet.

Our friend, John, came over to help during the process. Since at the time I was 12-ish weeks pregnant and was too sick to move (and I wasn’t aloud to pick up anything heavy)!

Then once they had the countertop in the garage it was time to get to cutting. Jon used a T-square to ensure that he kept a straight line. He also clamped the T-square to the butcher block so that it wouldn’t move. Jon used a Porter Cable Router with a half-inch straight-cut bit. He went around the template 1/4-inch to 3/8-inch deep each pass. It took about 4-5 passes until he was completely through the butcher block. Cutting Butcher Block for an Undermount Sink

After over an hour and a half of cutting they were done. It’s definitely helpful to have an extra set of hands. Once the sink was cut out, they moved the butcher block back into the kitchen and  Jon started to sand the inside of the sink to smooth out the edges. Cutting Butcher Block for an Undermount Sink

And then he began sanding the rest of the countertops. And that my friends is what our kitchen looked like for a while! Our takeaways on cutting butcher block for an undermount sink:

  • Trace the sink template in the exact spot you want it cut out in. Make sure you account for your front edge and enough space to mount the faucet. The template will not show you this.
  • Use safety equipment when cutting.
  • Try to take a practice run on a remnant piece of the countertop before you take the plunge cutting your actual countertop.
  • Use a high-power Router with a half-inch straight-cut bit.
  • It will take you a few passes (4-5)just to cut through the butcher block. Take your time.
  • Use a T-square to ensure you are cutting a straight line.
  • Use clamps to secure the T-square.
  • Once the sink is cut out sand the inside and edges to ensure a smooth finish.

  1. Hello fellow DIYers.

    I’m about to tackle and under mount sink installation myself and found your post really helpful, although I’d love some more info on how you managed the curved corners of the cut, did you have a template or was it a free hand situation?

    Kind regards,


    • Hi Holly, Yes we had a template. Our sink came with a template that we drew on the butcher block with a pencil. I think all sinks should come with that but maybe not?!?! Good luck! You can do it! Slow and steady wins the race. I think it took us around 2-3 hours to cut the undercount sink hole in the butcher block.

  2. Loved your tutorial and I have a couple of questions! Where are your butcherblock counters from and what did you stain and finish with, if you did, thanks!

    • Hi Carolyn, we bought ours from Ikea. They’ve since changed the formula and they are no longer solid–now hollow; however, you can’t tell once they are on the counters. We did not use stain on our counters we used a food safe butcher block oil to seal the wood. Hope that answers your questions!
