Install an Undermount Sink in a Laminate Countertop

What You'll Need
3/8" drill bit
Tape mesaure
Denatured alcohol
Saber saw or keyhole saw and handsaw
Latex caulk and gun
Plumbers putty

We are going to show you how to install your new undermount sink in a few moderately easy steps. First we are going to give you a list fo what you will need to get the job done. If your countertop is precut for the sink, you will not need to do most of these steps.

Step 1 - Cutting the Opening (if your sink is pre cut skip to step 3 )

Lay the counter top upside down on your work area. New sinks will come with a template for you to use to cut your opening. Or you can use the sink itself to make the opening you want. Using your measuring tape, measure off where you want the sink and mark it. Then using either the template or the sink itself (lay it upside down) Draw around the template or the sink with your pencil. Double check to make sure that the area you have marked is where you want the sink to be.

Step 2 - Cutting the Hole

Now we are going to cut the hole. Using your drill with the 3/8" bit, drill a hole in the corner to start and then using your saber saw, cut around the opening as closely as you can. If you don't have a saber saw use a hand saw for the straight lines and a keyhole saw for the corners. Now mark and drill the holes for the mounting screws.

Step 3 -  Mounting the Sink

Now using the denatured alcohol and the cloth, clean all around the opening where the sink will be sitting. On the cut,in the bottom, and on the top of the sink itself. Now run a bead of the caulking around the the hole on the outside,making sure you cover it well. Now place the sink upside down on the caulking. If there is ooze from the caulking, wipe it off with the cloth. Tighten the mounting screws. 

Step 4 - Putting the Sink Together

Go ahead and drill the holes for the faucet and mount them on the sink before you install it. Now turn the counter top over and attach according to the manufacturers instructions. Once you have the sink in place, apply the plumbers putt around the drain opening and push the drain down into the hoe snugly. You must allow the putty to sit up overnight. Apply all your water supply lines to the sink and to the connections. Put your drain trap together and attach it along with the drain pipe to the drain. 

Step 5 - Testing

Now is the big time. Turn on the water and check for any leakage that may happen. If there are leaks, re tighten all the fittings. Now enjoy your new sink that you installed.
