Most Australian homeowners would agree that the construction of a bathroom is incomplete without a good vanity in it.

Not only does it help upgrade your bathroom’s style, but it also offers counter space and storage. However, with time, the designs of bathroom vanities go out of fashion, and they need to be replaced with new ones.

How To Replace Bathroom Vanity

While replacing them may seem time-consuming and challenging, it doesn’t have to be. But having said that, we understand that if it’s your first time replacing a bathroom vanity, you might be a little sceptical about the entire process.

That’s why we have written this guide to teach you how to replace your bathroom vanity in a few easy steps. You need to have some experience for this, so keep the required tools handy, and be ready to shell out some dough.

Top 3 Reasons To Replace An Old Vanity

Before we jump into the process of replacing your bathroom vanity, let us take a look at why you should replace it in the first place.

1. Mouldy Bathroom Cabinets

Let’s face it, one of the most common problems with bathroom vanities is the growth of mould and mildew. Since they are always in contact with water, it leads to moisture buildup.

This causes the formation of rust and mildew in the bathroom cabinet, thereby weakening the structure. So, if that’s the case with your bathroom vanity, you need to replace it.

2. Extra Storage Space

If you have a pedestal sink, you might want to install a bathroom vanity for extra storage space. While these types of sinks are easy to install in the bathroom, they don’t offer much storage. In addition, with a bathroom vanity, you can easily hide all the toiletries inside its cabinets so that your bathroom looks organised.

3. Damaged Or Broken Countertop

If you have owned a bathroom vanity for a long time, it’s only natural to become damaged due to wear and tear. Hence, you will need to replace it with a new one.

Materials And Tools Required For Replacing A Bathroom Vanity

Here is a list of the materials and tools you would need to replace your bathroom vanity.


  • Putty
  • Tape
  • Caulk
  • Sink faucet
  • New bathroom vanity


  • Goggles
  • Gloves
  • Cleaning cloths
  • Bucket
  • Caulk gun
  • Power drill and bits
  • Adjustable wrench
  • Utility knife
  • Hole saw kit
  • Stud finder

How To Replace Your Bathroom Vanity

These are the steps that you must follow to replace your bathroom vanity:

1. Choose Your New Bathroom Vanity

First things first, you have to choose your new bathroom vanity. With the availability of many designs on the market, it’s essential to decide whether you want a bathroom vanity with or without an attached top.

From granite to marble, you will come across many options but go with one that best suits your lifestyle.

2. Disengage The Sink

Now that you have chosen your bathroom vanity, it’s time to remove the old one. First, you will have to disconnect the sink by turning off the water valves to the existing sink. Also, we would suggest you open the faucet to get rid of any remaining pressure.

Below the sink, you will find the P-trap drain pipe. Place a bucket or a towel under it to collect any water from the trap. Proceed to unfasten the nut at the top of your P-trap, detach the trap from the sink drainpipe, and ensure that you obliterate the trap.

3. Disengage The Water Lines

Next, you have to disengage the water lines from the valves. You can use a utility knife to cut the sealant or the caulk that joins the sink’s backsplash to the wall.

4. Detach the Old Vanity And Mend The Wall

Unfasten the screws that hold your bathroom vanity and pull it out. If the wall area seems damaged, make sure you repair it before installing a new bathroom vanity.

You can use a paintbrush or a putty knife to restore the wall.

5. Measure And Mark The Area For Your Bathroom Vanity

Mark out the new spot according to the dimensions of your new bathroom vanity. A stud finder can make it easier to locate and mark the studs within the outline. This is one of the most important steps, so it’s essential to be careful. 

6. Install Your New Bathroom Vanity

Ensure that your vanity cabinet is aligned with the marks you have made on the wall. If needed, you can remove the doors to make assembly easier. What’s more, you can use shims to adjust the height if required.

Once you have evenly placed your bathroom vanity, use a drill driver to drill pilot holes into the nearest studs and tighten the screws. However, if there are no studs to drill the screws into, you will have to use wall anchors; make sure you buy the correct ones.

7. Assemble The Bathroom Vanity Top

If it doesn’t feature an attached top, you will have to dry-fit the vanity top. First, ensure no gap between the vanity and the wall before applying caulk to the cabinet’s top. Hold the vanity top into position and press down with all your strength.

Check that the vanity top is flush and level with the wall. If your bathroom vanity doesn’t have adjustable legs, you can consider using shims under the base till it is even on each side.

8. Attach The Faucet And Reconnect The Supply

Follow the manufacturer’s instructions to attach the faucet. After connecting the faucet, fit the P-trap to the new sink line, and check all the connections to ensure no leak and everything is working fine.

How To Maintain Your Bathroom Vanity

You must know how to maintain the components of a bathroom vanity so that you don’t have to worry about a replacement for a long time.

1. Maintenance Of The Countertops

You must prevent water from damaging your countertops and the surrounding walls. Inspect the caulk every year to ensure that water cannot seep in and cause damage.

If you find that the sealant is weakening, get rid of the existing bead and apply a new one. Sealants and caulks can last up to 20 years when taken care of with ingenuity.

2. Maintenance Of The Faucets

Besides regular cleaning, one of the most important steps in maintaining your bathroom vanity is taking care of the faucet. Faucets start leaking and dripping under the countertop or around the base with time. When it happens, you must replace the parts immediately.

Please don’t wait for it to get too bad as it will cause water damage to the surrounding floors and the cabinet.
