 How To Install Bathroom Vanity Yourself: The Best Way

How To Install Bathroom Vanity Yourself: The Best Way

Just like kitchens, bathroom renovations offer some of the best bang-for-your-buck! Simple things like replacing a sink, basin or vanity unit will make a massive difference and are relatively easy to do yourself. When doing your own house and bathroom renovations, you need to measure twice and cut once. The same principle applies with your planning and how you do the renovation as well. You plan the installation steps twice, and you do them once. 

In this blog, we will walk you through the steps you need, as well as some insightful tips, on how to install your new bathroom vanity.

When Do You Need To Install Bathroom Vanity Yourself?

Here are some of the main situations you might find yourself in when you need to install a vanity unit yourself!: 

To Save Money

Installing the vanity unit yourself can save you a lot of money. Call out fees for plumbers for something that is minor and you can do yourself can be wasted money. However, you need to make sure you know what you’re doing because the mistake made could be even more expensive to fix.

To Save Time 

Sometimes, plumbers can be fully booked. The renovations you are undergoing may have a close project management time frame. The solution? Have a go yourself! Again, you will want to make sure to do it properly the first time otherwise it could take longer than the wait for a plumber. 

Because You Want To!

Doing your own renovation can be extremely rewarding and is increasingly popular, particularly with the bathroom. People often find an old cabinet or unit that they refurbish into a vanity unit and install. If this sounds like something you’re interested in, have a go!

Things You Need To Install Your Own Vanity


  • Stud finder.
  • Tape measure.
  • Hole saw.
  • Hammer.
  • Cordless drill.
  • Screwdriver set. 
  • Pencil.
  • Spirit level
  • Caulk/silicone gun.
  • Blade/cutting tool.
  • Scraper/spatula.
  • Soft clean cloth.
  • Jigsaw (situational). 


  • Vanity unit and new tapware.
  • Silicone/caulk 
  • Mineral turpentine/paint thinner or similar.
  • Screws.
  • Water supply tubes.
  • Filler strip (situational).
  • Wood finish materials (situational).
  • Paint (situational). 

The Steps to Install Your Vanity 

Step One

First thing you need to do is disconnect the plumbing in your bathroom.  The last thing you want to do is flood your house.

Step Two

Next you will want to remove the old vanity. Use your scraper and a hammer to dislodge anything you need. Then use turpentine to clean the area.

Step Three 

Locate the wall studs using the stud finder. This is easy to do and shouldn’t take long.

Step Four

Now, you will need to measure and mark out on the wall where the new vanity will go. Transfer the dimensions of the new vanity onto the wall. Do this twice to be double sure it is going in the right spot.

Step Five 

It is time to move the new vanity into position. Use a leveler to make sure the vanity is flush both side-to-side and back-to-front. If required, for things like floating vanity tops, you will also need to drill and fasten relevant parts.  Again, make sure you measure twice and cut/drill once.

Step Six

You will then need to install the vanity top, if it is not already done because the sink is seperate from the counter top.  Install the faucet and drain fittings, following manufacturer directions. Use bits of silicone to glue and seal parts of the counter top.

Step Seven

Then, you will need to connect the plumbing. Connect the water supply lines to the faucet, and connect the sink drain to the drain trap and branch drain.

Step Eight

Lastly, you need to caulk and silicone any of the joints and gaps you have missed. Take your time with this, this is the last step and will put some TLC into your vanity unit. 

Some Tips to Remember 

Make sure when installing a bathroom vanity yourself, you often clean and dry surfaces of oil, dirt and grease off surfaces. Make sure you allow time for any product to dry before applying silicone. When silicone is wet and you are using it to fix the vanity top to the unit, it has a level of wiggle room. Once it is dry it won’t move. When you’re using any product for the first time, test it on a piece of scrap to make sure it is what you need. Use a spatula/scraper dipped in detergent and water to tool off any sealant.
