Removing the Old Vanity

To make way for your new bathroom vanity, you’ll first need to remove the existing one. Here’s how:

  1. Turn off the water supply: Locate the shut-off valves under the sink and turn them clockwise to shut off the water supply. Turn on the faucet to release any remaining water in the pipes.

  2. Disconnect the plumbing: Use an adjustable wrench to loosen and disconnect the water supply lines from the faucet. Place a bucket or towel underneath to catch any water that may drip.

  3. Remove the sink: If your vanity has a separate sink, detach it from the countertop by loosening the mounting clips or brackets underneath. Carefully lift the sink and set it aside.

  4. Disconnect the drain pipe: Loosen the slip nut connecting the drain pipe to the main drain line using a pipe wrench. Once loose, pull the pipe away and remove any leftover water.

  5. Remove the vanity: Start by removing any caulk or adhesive holding the vanity to the wall using a putty knife. Then, unscrew the vanity from the wall and carefully lift it away, taking care not to damage the surrounding surfaces.

With the old vanity out of the way, you’re ready to move on to the installation of your new bathroom vanity.

Installing the New Bathroom Vanity

Now comes the exciting part – installing your brand-new bathroom vanity! Follow these steps to ensure a smooth installation process:

  1. Measure and mark: Use a tape measure to determine the height, width, and depth of your new vanity. Transfer these measurements to the wall, making sure to account for any baseboards or existing plumbing.

  2. Locate studs: Use a stud finder to locate the wall studs behind the vanity area. Mark their positions with a pencil, as you’ll need to secure the vanity to these studs for stability.

  3. Make necessary adjustments: If your new vanity doesn’t align perfectly with the existing plumbing, you may need to make adjustments. Use a hole saw to create an opening in the back of the vanity to accommodate the pipes.

  4. Position the vanity: Carefully position the vanity against the wall, aligning it with the marks you made earlier. Use a level to ensure it’s perfectly straight, and adjust as needed using shims.

  5. Secure the vanity: Once the vanity is in place, use a drill to attach it to the wall studs. Pre-drill pilot holes to prevent splitting, then insert screws through the back of the vanity and into the studs.

  6. Connect the plumbing: Reconnect the water supply lines to the faucet, ensuring they are tightly secured with an adjustable wrench. Apply plumber’s putty to the sink drain opening and attach the drain pipe using slip nuts.

  7. Install the sink: If your new vanity has a separate sink, follow the manufacturer’s instructions to mount it securely to the countertop. Use silicone caulk to seal the edges of the sink, preventing any water leakage.

  8. Finishing touches: Once the plumbing is connected and the sink is in place, it’s time to add the final touches. Attach any included hardware, such as drawer pulls or knobs, and secure them with a screwdriver or drill. Use finishing nails to install any decorative trim or molding for a polished look.

Congratulations! You have successfully installed your new bathroom vanity. Take a step back and admire your handiwork. Your bathroom has undergone a stunning transformation, and you can now enjoy a functional and stylish space.
