Here comes a more important question: How to install a bathroom vanity? Follow these step by step guides to find out.
1. Preparation: Removing the Old Vanity
First things first: Before you start removing your old vanity, make sure to turn off the water supply—otherwise, you risk turning your bathroom into a mini lake! Once the water is off, place a small bucket under the P-trap to catch any leftover water. Then, carefully disconnect the water supply lines and waste pipes using an adjustable wrench.
With the plumbing disconnected, you’re ready to remove the vanity. Use a utility knife to cut through the caulk, unscrew the vanity from the wall, and gently take it out. If you’re doing this on your own, try to remove the vanity in one piece.There’s no need to smash it apart—you can sell it to earn some extra money.
Finally, before moving forward, inspect the area for any signs of water damage or mold and make any necessary repairs.
2. Marking and Positioning the New Vanity
Once the old vanity is removed, it’s time to mark and position the new one. Start by deciding where the vanity will go—whether it’s floor-standing or wall-mounted. If it’s freestanding, simply place it in the desired spot. For wall-hung vanities, use a stud finder to locate and mark the wall studs for secure mounting, and ensure the unit is level before moving forward.
Next, mark the exact position of the vanity and measure and mark where the plumbing will connect on the back or base of the vanity to ensure everything lines up properly.
If needed, drill holes in the vanity’s back panel or base to allow access for plumbing connections.
3. Assembling the Vanity
Next, move one step closer by assembling the vanity according to the manufacturer’s instructions. Take your time to ensure everything fits properly and is securely in place.
If you’re mounting the vanity on the wall, take your time and be cautious—rushing can lead to accidents or poor installation. Wall-hung vanities must be securely anchored to prevent them from falling or shifting, which can be dangerous.
Before installing the basin, it’s a good idea to pre-fit the tapware and waste fittings. Doing this now will make the job much easier and help you avoid working in tight or awkward spaces once the vanity is mounted.
4. Positioning and Securing the Vanity
After you’ve assembled and marked it, it’s time to finally secure the vanity in place. To do that, you’ll need a spirit level to ensure the vanity is perfectly leveled and plumbed. As we mentioned earlier, for floor-standing vanities, mark anchor points on the floor and wall, drill pilot holes, and insert appropriate wall plugs or anchors.
For wall-hung vanities, install a mounting bracket securely fixed into studs or masonry, then hang the vanity and check that it is level.
5. Installing the Bathroom Vanity Top
To finally install it, fit the vanity top yourself or with help to confirm proper alignment. Then, apply a bead of silicone caulk around the top edge of the cabinet. Be careful when placing the vanity top—press it firmly to create a watertight seal. Seal the edges where the vanity top meets the wall with silicone to prevent water ingress.
6. Reconnecting Plumbing
Now it’s time to connect the tapware to the water supply lines. We recommend using plumber’s putty or thread seal tape to ensure a tight seal. Next, attach the P-trap to the basin waste and connect it to the existing drain. Finally, turn the water supply back on and check all connections carefully for any leaks. If you find any leaks, it’s best to contact a professional plumber to fix the issue properly.
7. Final Touches
For the final touches of , you can now install the vanity doors and drawers. Add extra silicone sealant where needed to prevent future leaks, especially around small gaps on the countertop. Finally, clean and decorate your bathroom vanity, and you’re good to go!

FAQs
1. What If My Bathroom Walls or Floors Aren’t Level During Vanity Installation?

2. Can I Reuse My Old Countertop and Sink with a New Vanity?
Yes, you can reuse them if they’re still in good shape and match the size of your new vanity. Be careful when removing them, and double-check that the mounting holes line up. If they don’t, you may need to adjust or buy a new countertop for a better fit.
3. What Materials Are Best for Bathroom Vanities in Melbourne’s Climate?
Go for moisture-resistant materials like PVC, marine-grade plywood, or waterproof-laminated MDF. These hold up well in Melbourne’s changing weather and help prevent swelling, warping, or mold in humid bathroom spaces.
