First Things First
While this isn’t a how-to choose your new sink post, there are a few preliminary steps to take before you begin your sink installation. First, make sure you’re comfortable with the process and tools needed to install the sink you select.
The most common sink styles installed in kitchens and baths are:
If you’re looking for the most simple sink to install as a DIY project, go with a top-mount sink.
Three types of sinks popular for bathrooms are pedestal, console, wall-mount, and vessel. In the bathroom, consider using a vessel-style fixture like these concrete sinks. You’ll create a unique and modern vibe without stressing out over a challenging sink installation.
Before you start the installation, measure the existing sink. Taking measurements ensures you know your drains’ position and whether your new sink will fit the space.
It’s possible the new sink won’t have the same dimensions as the old one. In that case, you’ll likely need to alter the countertop. If you’re not comfortable hacking into countertop material, especially if it’s stainless steel or stone, you can always hire a professional to make the necessary alterations.
Tools of the Trade
To help sink installation goes as smoothly as possible, you’ll want to gather your tools before starting the project. Make a list of things you don’t have before you shop for the sink so that you save yourself an extra trip to the hardware store.
Your tool belt should include:
- Adjustable Wrench
- Channel-Lock Pliers
- Putty Knife
- Plumber’s Putty
- Caulk Gun
- Silicone Caulk
You’ll also need a bucket to collect any water that drips out when you disconnect and remove the old sink. A razor blade will help you remove the existing sink. Buy a replacement sink strainer in case the new sink doesn’t come with one.
Say Goodbye to the Old Sink
As excited as you are to get the new fixtures installed, it’s not as simple as out with the old and in with the new sink. Removing the current sink requires several steps. Before doing anything else, turn off the water.
You’ll find the water supply lines under the sink, which is also where you shut the water to the sink off at the valves. Sometimes valves aren’t easy to locate. If you have trouble tracing the valves, you can turn the water off at the house’s main water supply.
Tip: Before disconnecting the water, take a picture of your pipe and valve configuration. You may need it when you reconnect the water supply lines.
Next, turn on the faucet, which relieves the water pressure and drains the water lines. After draining the water supply lines, you’ll use the wrench to disconnect the supply lines. It’s an excellent time to have your bucket near-by.
Are you installing a kitchen sink with a garbage disposal? If so, disconnect the disposal lines. After you’ve collected any drips, turn off the circuit for the disposal and unplug the unit.
If you’ve ever wondered about P-traps, now is your chance! The next step in the sink installation is to detach the P-trap and let it drain into your bucket. Now, remove the motor for the disposal.
All the Little Details
Once you have the supply lines and disposal motor removed, you’re ready to remove the old sink. It would help if you had the screwdriver handy for this step as you’ll be using it to move the clips holding the sink in place. You’ll find the clips below the sink.
Notice the caulking around the sink. Use a razor to break the seal on the old caulk, and use the putty knife to cut the caulk away from the sink.
Now, you can push the old sink from the bottom and remove it. You may need several pushes to separate the sink from the countertop. Scrape away any grimy buildup left on the countertop.
How to Install a New Sink Step-By-Step
Remember earlier when we mentioned the easiest sinks to install? If you chose one of those, the rest of the installation project should come together without a hitch.
You checked the fit previously. Now place the new sink into the hole in the countertop and do a double-check. If it’s still a good fit, attach the clips, and ensure they all face the sink bowl.
Here’s your chance to show off your skills with plumber’s putty. Roll a small amount of putty into a thin strip.
Did you remember the sink strainer? Apply the putty strip to the stainer by rolling it around the strainer’s edge and the drain. Place the strainer in the drain and press firmly.
There’s one more step before you can complete your sink installation. The sink comes with rubber gaskets, which go on the drain. Stand the sink sideways, place the rubber gaskets, and thread the flange.
Don’t let excess putty stay in the drain or the bowl of the new sink!
Almost Time to Debut the New Sink
Your final installation includes screwing the mounting bracket to the sink. Next comes applying the silicone caulk under the sink. Now you’re ready to lower the sink into the hole in the countertop and align it correctly.
You’ll need to rotate the clips so that they face towards the sink bowl. Take the silicone caulk and caulking gun, seal around the sink’s rim, and wipe off the excess caulk.
You saved the water supply lines, disposal lines, and P-trap. Now you can reattach them and then attach the sink fixtures. Voila – time to turn the water on!
