Are you considering installing a granite countertop on a bathroom vanity but don’t know how to do it? You have come to the right place! You don’t always need professional services for this purpose. It is an easy process if you have the right knowledge. First of all, you need to ensure that the bathroom vanities on which you are considering installing the granite countertop is sturdy and level. Then, you can apply the construction adhesive you select (we suggest silicone caulk) to the top edges of the vanity.

After that, carefully and slowly place the granite slab on the adhesive. You must make sure it is properly aligned. Now secure the countertop with screws and brackets through the drilled holes in both the vanity and the countertop to ensure durability. And you’re done! If you are not confident enough to perform the process yourself, consider getting it done professionally from a reputed countertop company.

4 Steps on How To Install a Granite Countertop on a Bathroom Vanity

Here, we have listed each step in detail to help you with the installation process:

Step 1: Selecting the Granite Countertop

First of all, you need to select the granite countertop surface material you want to install on the bathroom vanity. Before jumping into your car and driving to the nearest home improvement store, consider getting a template of your existing bathroom countertop, showing the position of the faucets and the sinks. This helps ensure that the new countertop you will purchase is of the accurate size. However, if you work with a reputed countertop company, you will not have to worry about incorrect sizing. Our professionals will come to your place and measure the space to ensure the correct sizing.

Step 2: Removing the Old Countertop

Now that you have selected the new granite countertop you want to install on your bathroom vanity, let’s move on to step 2, which is to remove the old countertop. To do that:

Turn off the water for the bathroom sink using the valves under the sink.
Run the faucets until no more water comes out.
Use a wrench to loosen the connections for the hot and cold water pipes.
Then, loosen the sink drain.
Use a knife to remove the caulk where the sink meets the countertop.
Carefully lift out the old sink and set it aside.
Use a pry bar to remove the old backsplash.
Unscrew the old countertop from the cabinet to remove it.

Step 3: Installing the Granite Countertop

After removing the old countertop, your DIY countertop installation process begins! Are you excited yet? Here is how to do it:

Pull up the granite bathroom countertop gently to see if it fits right. If it’s long, you can ask a partner to help lift it safely.
Always remember to bend your knees while lifting.
Lift it again and put a thick line of sticky silicon under it where it will sit on the cabinet. Then, put the countertop back and let it dry for an hour.
Next, put the faucets on because they’ll be outside the sink.
Tighten them in place and connect them to the hot and cold water pipes with a special wrench.
Put the sink in its place to check if it fits well.
Once it fits nicely, take it out and put a line of clear sticky stuff around the lower rim where the sink meets the countertop.
Then, put the sink back and connect it to the drain.
Lastly, put a thin line of clear sticky stuff between the faucets and the granite countertop.

Step 4: Backsplash

Now it’s time for the backsplash.

Put the silicone caulk on the back of your backsplash.
Push it in next to the granite countertop.
Let it sit for an hour.
Then, add silicone caulk stuff between the backsplash and the countertop.
Check if the water works.
Clean the granite and sink with a wet cloth to remove dust.

And that’s it! You’re done!
