How to Install a Kitchen Sink – The Perfect Way

Having a new, shiny kitchen sink and kitchen faucet can really upgrade the look of your kitchen. However, there is one thing to do before you start admiring your new kitchen sink – first, you need to install it.

Now, if you’ve never done that before, you might be terrified of all those parts and the kitchen sink size. But, don’t worry – installing a new sink is much simpler than you think.

And in this article, we’ll prove to you that. We bring you a detailed description of how to install a kitchen sink, so keep on reading.

Part 1: How to install a kitchen sink

In order to make installation as simple and fast as possible, you should prepare all the tools needed and read the instructions that you got with a kitchen sink. That way, you’ll know what to expect. And by having the tools ready, you won’t waste time on looking for them, once you start installing the sink.

Step 1: Determine Countertop Opening

A template should also be included alongside your new kitchen sink. This template shows how large the countertop opening should be to fit your new sink.

According to the template, mark the countertop in places that you need to cut. Then, place the sink on the counter, turning it upside down. Now, check whether the marks on the counter are in alignment with the sink’s marks. If not, adjust them.

Just make sure the sink is paralleled with the countertop’s edge. Lastly, mark the position of the sink and remove it.

Step 2: Make cut-out lines

Now, you need to make the cut-out lines on the counter. Use a straightedge to do that. After that, drill a hole in every corner of the cut lines.

Step 3: It’s time for action!

Now that everything is ready for your next move, it’s time to use a jigsaw to cut the lines. The holes you previously made will serve for lowering a jigsaw blade and sawing along the cut line.  Repeat this process on the other side.

When done, remove the piece you just cut out.

Then, place the sink on the counter to see if they match perfectly. If not, mark the part you need to widen, and then use a jigsaw to do that.

Step 4: Install the strainer and garbage disposal

Just to note, you should set a tailpiece, pipes, washers, and other hardware before you install the sink. So, place the sink upside down on the counter and get to work.

Before installing drain pipes, first, install a basket strainer and garbage disposal.

Also, it’s better to install garbage disposal first because it takes much more space than a basket strainer. Choose the side of the sink where garbage disposal should be and install it.

Step 5: Install a kitchen faucet and sink drain

Install the kitchen faucet, supply tubes, and tailpiece. When installing supply tubes, they need to be long enough so as to reach the stop valves.

Then, screw the washers and the mounting nuts.

If you want to install a water filter, an icemaker supply, or a dishwasher supply, now it’s time for that. Doing so will make installing the sink a whole lot easier since most of the work will already be done.

Step 6: Set a kitchen sink

When everything is in place, you can install a sink.

But before doing that, put a drop of silicone caulk in the region underneath the sink’s lip. After that, turn the sink straight and place it in the countertop hole.

The sink should be parallel to the front edge of the countertop. If not, adjust it.

Step 7: Connect the kitchen faucet

Since you successfully installed the kitchen sink, you just need to connect the kitchen faucet to shut-off valves.

Part 2: How to install a kitchen sink drain

When installing a kitchen sink and faucet, you also need to learn how to install kitchen sink plumbing. The largest part of the job is done, but you still have to do this part to make your sink functional. So, here’s how to install a drain.

  • As you probably already know, the drain trap has a U-shape part and a J-shaped arm. The first part fits onto the base of the tailpiece and the arm goes into the sanitary tee fitting in the wall.
  • Bring together the trap and arm loosely using slip nuts.
  • Connect the trap to the tee fitting on the sink drain. At the same time, you need to attach the arm to the sanitary fitting in the wall.

You want to create a straight path from the sink to the wall tee in order for the water to pass freely through pipes. Also, the trap arm should have a slightly descending angle pointed to the wall tee. Otherwise, there will be standing water.

  • Now that everything is connected, make sure to tighten the slip nuts. However, don’t overdo it.
  • The last step is to check whether you installed a sink drain properly. To check that, run the faucet and search for leaks. If there are some leaks, just tighten the slip nuts a bit more.
  • Well, congratulations – you made it! Now, you can enjoy using your new kitchen sink!

The Final Word

And there you have it – steps for fast and easy installation of your kitchen sink and a sink drain. Who would think that this job isn’t so complicated, huh? Before you start, make sure to prepare all the tools and instructions, so that you can focus on the task at hand. Also, be patient, and don’t try to rush things. Good luck!
