Those up to the challenge will need the following tools:

  1. Grease pencil
  2. Ruler
  3. Hammer
  4. Hand file
  5. Drill with 4-millimetre flat bit
  6. Jigsaw

Cutting the Counter

With the correct tools in hand, you’re ready to get started installing your dream granite drop-in sink. It’s wise to be extra precise during this stage, as your marks and cutting will ultimately determine the success of the entire project. As with anything that requires the use of an automated blade, safety goggles and caution are highly recommended.

Step 1

Find the paper template enclosed with the sink and place it on top of the counter in your desired location. Fit the paper into the centre of the sink base cabinet so that it has at least 3 inches of space in front and in back of the sink. Once this is done, trace the outline of the template onto the counter using the grease pencil.

Step 2

Determine the overlap distance by consulting that manufacturer’s manual located on the sinks template. This will tell you how much of the counter must lie beneath the rim of the sink.

Measure the overlap distance and then use the grease pencil to draw a line inwards from the original outline. Redraw a second line with the overlap distance in consideration inside the first, this will be the line which you cut.

Step 3

Now it’s time to use your drill with a 4-millimetre flat bit. Locate the four corners of your interior line markings. Remember, precision is crucial.

Step 4

For this step, it’s helpful to enlist the assistance of another person. Insert the blade of your jigsaw into one of the holes you’ve drilled into the corners.

Cut out the counter along the interior lines drawn. Use a helper to hold the counter from the bottom when you’re cutting as it ensures that it won’t pull away or splinter during the process.

7 Steps to Install the Granite Sink

Now that you have your accurately sized hole, it’s time to install the sink. This process proves easier than the cutting but requires just as much care and accuracy.

Following instructions closely here makes the difference between a perfect finished product or needing to start all over again.

Step 1

Hold the sink vertically, with the top facing away from you so that you can see where the faucet holes are located. Typically, you will find several holes with colored tape around them.

Consult the manufacturer’s manual for assistance in determining which are the correct holes. Once identified, place a center punch on the colored tape of the holes.

Hit the punch with the hammer until the hole pops out. Clean the edges using a hand file to ensure they are completely smooth.

Step 2

Before going any further, it’s time to double check that everything has been measured and cut correctly. Lower the sink into the counter hole. If it fits well, you’ve done a great job so far.

Step 3

Lay the sink on a flat surface with easy access to the newly formed holes. Install the faucet by inserting the stems into the holes and use a wrench to tighten the bolts.

Step 4

Next, roll a piece of plumber’s putty until it’s approximately ¼ of an inch in thickness. Once this is done, press it around the sink drain and make sure it’s evenly smooth in distribution.

Press the gasket and washer onto the backside of the strainer and turn tightly until they are locked securely in place. Inspect the work by turning the sink over. Any excess putty visible should be wiped away with a clean cloth.

Step 5

Turn the sink upside down and pour the silicone caulk around the entire perimeter of the sink’s rim. Be generous in this process as the caulk will be responsible for holding the sink in place while withstanding the general wear and tear associated with activity in the kitchen.

Step 6

Carefully lower the sink into the counter. Before doing so, make sure you’ve located the sink clips on the underside of the sink.

Rotate them so they contact the underside of the counter and tighten them using a wrench, assisting in the security and durability of the sink.

Step 7

Admire your handiwork and wipe away the excess caulk that may have seeped outside the perimeter of the sink. Attach the water supply lines to the faucet and the drainpipe to the sink.

Turn on the water and make sure everything is operating properly.
