Otherwise, move on to the next step.

Step 4: Assemble Your Kitchen Cabinets

Follow the manufacturer’s instructions to assemble your kitchen cabinets according to the dimensions you have chosen for your vanity. It’s important to ensure that all pieces are level and secure before moving on. It’s also a good idea to add additional support for the countertop by placing screws in strategic areas, especially if you plan on using heavy materials. You can also paint or stain the cabinets at this stage if desired.

Step 5: Cut the Plywood or MDF board for the Countertop

Using a table saw, cut the plywood or MDF board to fit on top of your assembled kitchen cabinets. Make sure the edges are smooth and even. You may also want to add pre-drilled holes for your sink and faucet, as well as any other accessories you plan on including in your vanity. It’s recommended to use a waterproof material for the countertop to prevent damage from water and moisture.

Step 6: Attach the Countertop to the Cabinets

Carefully place the countertop piece on top of your assembled cabinets and secure it using screws from underneath. It’s important to make sure everything is level before attaching it permanently.

Use Shims if Needed to Adjust the Height of the Countertop

Use shims if needed to adjust the height of the countertop. But make sure not to over-tighten the screws as it can cause damage to the countertop or cabinets. It’s also recommended to add caulking around the edges of the countertop for a clean, finished look.

Step 7: Install the Sink and Faucet

Follow the manufacturer’s instructions to install the sink and faucet onto the pre-drilled holes in the countertop. Make sure everything is properly tightened and connected. You can also use a plumber’s putty or silicone caulk around the edges of the sink for a watertight seal.

It’s also a good idea to install any additional accessories, such as a backsplash or side splashes, at this stage. But if you plan on tiling the backsplash, it’s recommended to do it after installing the vanity.

Step 8: Add Cabinet Hardware

To complete the look and functionality of your vanity, add cabinet hardware such as knobs or pulls. Measure and mark the desired placement before drilling holes for the hardware. Make sure everything is level and centered for a professional finish. But if you want a more modern look, you can also opt for touch-activated or push-to-open hardware instead. It all depends on your personal preference.

Step 9: Install the Vanity to the Wall

If your vanity is not freestanding, it’s important to secure it to the wall to prevent tipping over. Use screws and anchors appropriate for your wall type and make sure everything is level before attaching it permanently. It’s also a good idea to add additional support underneath the cabinets in case of heavy items being stored inside. This will also prevent sagging or warping of the cabinets over time.

Use Screws and Anchors Appropriate for Your Wall Type

Step 10: Connect Plumbing

Reconnect any plumbing that was disconnected earlier. If necessary, consult a professional plumber to ensure everything is properly connected and there are no leaks. Turn on the water supply and check for any issues before proceeding with the finishing touches.

It’s also a good idea to add silicone caulk around the edges of any plumbing connections for added protection. It’s important to let the caulk dry completely before using the vanity.

Step 11: Finishing Touches

Once everything is secured and connected, it’s time for the finishing touches. You can add a backsplash or side splash if desired, as well as sealing all edges with waterproof caulking. Finally, clean up any debris and make sure everything is in working order before using your newly made bathroom vanity from kitchen cabinets!
