How to Install Your New Farmhouse Sink in Existing Granite Countertop

Tools and Materials You’ll Require:

  • A new farmhouse sink
  • A pair of protective goggles
  • Measuring tools
  • Tile saw
  • Reciprocating saw, or hand saw
  • Painters tape
  • Pencil or marker
  • Piece of cardboard
  • Wooden blocks
  • Screws
  • Power drill

The Installation Process

  • Step 1: Remove the old sink

To make room for the new farmhouse sink, you have to remove the old one. Do this by carefully cutting through the silicone around the edge of the sink and disconnecting the plumbing pipes.

If you can get a pair of helping hands, the better. The process will be easier for you with someone to hand you the tools.

  • Step 2: Cut the granite

The process of cutting the granite is a messy one. At this point, you need to wear your protective goggles and dust masks.

Measure the new sink and trace an outline on a piece of cardboard to ensure the right fit. Using painter’s tape, mark the areas for the cutout.

With your tile saw, cut the granite along a straight line. This should be easy since a tile saw comes with a guide that helps you learn how to keep your cuts straight.

The painter’s tape also helps you move the saw in a straight line.

  • Step 3: Remove the cabinet front

To install the sink, you must also adjust the front of the cabinet. Follow the template that comes with the sink for the best results.

Trace out the template and use a jigsaw to cut the outline. If you fear that you might err on your cutting, saw inside the lines and sand the excess.

  • Step 4: Cut the supporting frames

If your cabinet doesn’t have enough support to hold the new farmhouse sink, get some support frames ready for that.

Cut the wooden bars according to your measured sizes. Mark the bottom with a pencil and place the bars in their right positions.

Once you are sure that everything fits, use the construction adhesive to glue the vertical and horizontal supports. For a tight fit, secure them with screws.

  • Step 5: Install the sink

And now, it’s time to check whether the new sink fits or not. Let someone assist you in lifting the sink and carefully place it in the cutout space.

Double-check to ensure that everything is straight and level since you don’t want to encounter problems when using the sink later.

Apply caulking and let it sink before you reinstall the plumbing.

  • Step 6: Connect the plumbing

After fitting the sink, it’s time to connect the plumbing lines. This should take just a few minutes since you only need to connect the pipes and the faucet.
