Ever found yourself staring at one of your counter tops and just wishing you had an extra sink there? If so, you're not alone. Many people dream of installing a new sink—only to be hampered by what they consider an impossible undertaking. But you don't have to be a professional plumber to put in a new sink yourself. This article will provide two essential tips for installing a new sink in an old counter top.

Tip #1: Turn the sink upside down to measure the hole.

Any sink installation has to begin with cutting a new hole in your counter. And while this task seems simple enough on paper, it can be hard to nail in the moment. A little too small and the sink won't fit—a little too large and it falls right through. While the first case can be adjusted by widening the hole, the latter usually means replacing the whole counter top.

The first step is always to decide roughly where you want the new sink to go. Then, to ensure that you cut a properly sized hole, all you have to is turn the sink upside down. Trace all the way around the edge of the lip using a pencil—but don't start cutting yet!

Think about it. If you start cutting along the line you've just drawn, your sink will slip right through the ensuing hole. You therefore need to allow for a slight overhang, on which the lip of the sink can sit. Use a ruler to measure a second line inside of the first. 3/8" is the most common offset distance for this second line, but check with your sink's installation instructions to make sure this is right size.

Tip #2: Install the faucet before you install the sink.

Even simple tasks can become arduous and frustrating when you have to perform them flat on your back. That's why, as almost any plumber will tell you, it's a good idea to do as much as you can before putting the sink in its hole. In this case, that means getting the faucet installed.

Installing a faucet is fairly simple, tool wise; you shouldn't need much more than a towel, a pair of pliers, and some plumber's putty. Fold the towel and place it on top of the counter, so as to protect it from scratches while you work. Then place a bit of putty around each faucet hole to help guarantee a tight seal.

Here you can insert the faucet. Double check that you've got the hot and cold water lines on the correct sides, and then screw the nuts on finger tight. Now check again—this time to make sure that your faucet is centered properly. If so, use your pliers to finish tightening it up. Voila, your faucet is now installed in the sink!
