You may be intimidated at the thought of installing one of these sinks, but let us reassure you its a very simple process. Simply follow the steps below and you will be one step closer to your dream kitchen.

Preparation: If you are starting from scratch, you will need to install the faucets, and make sure the pipes line up with where your new sink will be placed. Cut the hole in your countertop to match the size of sink you are installing.

Tools: What you need to complete the project

  • measuring tape
  • scissors
  • power drill
  • bits
  • plastic putty knife
  • screwdriver
  • utility knife
  • caulk gun
  • jig saw
  • drop in sink
  • masking tape
  • carpenters pencil
  • silicone caulk
  • rag

Step 1:

  • Draw a template for the sink by setting it upside down on a piece of cardboard and drawing a line around it.
  • Draw a second line around 3/4” inside the first line
  • Cut the inside line with scissors

Step 2:

  • Find and mark the center of the counter top, do this by measuring the length and width from under the sink
  • Drill a hole large enough for a nail in the exact center

Step 3:

  • Find and mark the center of your cardboard template
  • Put a nail through the center of the template
  • Align the center of the template with the center of the counter top and use the nail to secure that the two pieces are exact

Step 4:

  • Make sure the template is perfectly square and trace it onto the counter top
  • Remove the template and use masking tape to mark the lines you drew
  • Replace the template and trace the outside of the cardboard onto the tape

Step 5:

  • Use a drill and a 3/4” spade bit to start a hole for the saw. Start on the corner of the line you drew on the tape

Step 6:

  • Support the underside of the counter top with a brace of some kind, ie: a 2x4

Step 7:

  • Cut along your line using a down-cutting 5/16” wide laminate or similar saber saw blade. Make sure the blade is designed to cut counter tops without chipping.
  • Remove cut portion from counter top.

Step 8:

  • Test the sink in the opening
  • If the sink fits, draw a light line along the counter top around the sink
  • Remove the sink and apply a continuous bead of caulk between the line you drew and the opening

Step 9:

  • Carefully place the sink in the opening
  • Press the sink firmly into the caulking
  • Check to ensure the sink is level

Step 10:

  • Connect the faucets and check for leaks
  • Clean up any excess caulking from around the sink with a putty knife and a rag.
