Sink Installation: What’s Involved


If you are considering installing a kitchen sink, take heart. Your apprehension isn’t without cause, but you should also remember that you are not attempting to build a Space Shuttle. Installing a kitchen sink can be tricky, but it’s been done by many people, and probably by people with less ability and know-how than you. With the instructions below you will have a kitchen sink that has been well installed before you know it.

1. Cut the New Sink Opening

Turn your new sink upside down on the counter-top where you want it. Make sure that it is at least 1 1/2 inches from the front edge of the counter-top. You need to make sure that there is enough room from the front of the counter that it retains its strength. Three or four inches from the front edge would be too far. Measure each end of the new sink to make sure that they are the same distance from the edge. You need to make sure that your sink is centered. Next, trace a line around the edge of your new sink. Now, move your sink away to reveal your tracing. Next, with a straight edge, measure a line inside of your trace line from 3/8 to 1/2 inch. This will be the actual cut line where your sink will sit.

Using a drill with a 7/8″ bit, drill a pilot hole in each of the four corners of your cut line. These holes are where you will insert the blade of your saw, so you need to make sure that they are big enough to allow your keyhole or jig saw to go through. Now cut along your cut line. You should try to make these cuts as straight as possible, but it’s also important to remember that your sink will go into this area with the lip covering it, so any imperfections of your cut won’t be seen.

2. Prep Your Sink

Turn your sink upright, then put plumber’s putty along the edge of the drain hole to insert your strainer. Now turn your sink upside down to tighten the screws underneath to hold the strainer in place. You might need to use pliers to hold the strainer still while you do this. Now you need to attach the drainpipe to the gasket, including plumbers putty for a good seal. If you are going to include a garbage disposer, you need to use a similar technique to attach it to the other side.

3. Install Your Sink

Apply a “rope” of plumber’s putty around the edge of the underside of your sink. Next, flip your sink over and carefully lower it into the hole in your counter. Press the sink down to make sure it is evenly applied to the counter. Now, underneath the sink, you need to attach and tighten the mounting clips, which will secure the sink to the counter. Next tighten the mounting clips to secure the sink. Connect your drainpipe as well as the faucet fixture and whatever other fixtures you want to include, and you’re ready to enjoy your new sink.
