2. Remove the old vanity

The next step is to remove the old vanity cabinet. You will do this by disconnecting the bathroom sink and removing the vanity cabinet. Be sure to remove all of the screws and hardware from the old vanity before discarding it.

Tip: If you are replacing an old vanity with a new one, take measurements of the old vanity so you can purchase a new one that is the same size.

3. Secure the cabinet to the wall

If you are installing a new vanity, securing the cabinet to the wall is vital. You can do it by drilling holes in the back of the cabinet and screwing it into place. If you are replacing an old vanity, the chances are that it was not secured to the wall and will need to be now.

4. Installation of a single-piece new bathroom vanity

If you are installing a single-piece vanity, the next step is to measure and cut the hole for the sink. Be sure to use a level when cutting the hole to ensure that it is straight. 

Once the hole has been cut, you can begin installing the vanity. The first step is to apply plumbers putty around the edge of the sink. Then, insert the sink into the hole and press it down. Use a wrench to tighten the bolts that hold the sink in place.

5. Installation of drop-in sinks

If you are installing a drop-in sink, the next step is to measure and cut the hole for the sink.

Be sure to use a level when cutting the gap to ensure it is straight. If you are using a template, it is very important to make sure the hole is cut in the right spot. The sink will not fit correctly if it is not in the correct position.

Once the hole has been cut, you can install the sink. First, apply a layer of silicone sealant around the edge of the sink. Then, set the sink in the hole and press it down firmly. Use a level to make sure it is straight. Finally, tighten the screws that hold the sink in place.

6. Attach vanity top to cabinet

The next step is to attach the vanity top to the cabinet. You will do this by using screws or anchors. If you are using screws, be sure to drill pilot holes first.

Tip: If you are using anchors, it is crucial to ensure they are the correct size for the vanity top.

Once the vanity top is attached, you can install the faucet. Be sure to follow the instructions that come with the faucet.

7. Attach the faucet to the bathroom sink

The final step is to attach the faucet to the sink. It is the same process for regular sinks or pedestal sinks. This can be done by using a wrench to tighten the bolts that hold it in place. Be sure to follow the instructions that come with the new faucet.

8. Connect the supply tubes

After you attach the faucet to the sink, make sure to connect the water supply through the tubes. You can do this by using a compression fitting or soldering the pipes together

9. Connect the drain line

The final installation step is to connect the drain lines. This tube runs from your sink to the drain on the floor. There are a few different ways to do this, so consult your installation instructions.

To connect the drain line, fit one end of the tube into the hole at the bottom of your sink. If your sink doesn’t have a pre-drilled hole, use a jigsaw to cut one. Then, fit the other end of the tube into the drain on the floor. Make sure it’s tight and sealed well with plumbers’ putty. Finally, screw on the drain cover.

10. Test for leaks

One of the most important steps is to test for leaks. Once everything has been installed, turn on the water and check for any leaks. If there are leaks, be sure to fix them before using your new vanity.

Is the bathroom vanity installation a DIY project?

While it may be possible for some homeowners to install a new bathroom vanity on their own, it’s best to hire a contractor in most cases.

This is because several plumbing connections need to be made, and without the proper knowledge, it’s easy to make a mistake that could cause a leak.

Plus, if you’re not familiar with your plumbing layout, it’s easy to cut a water line or damage a pipe accidentally.
