  2. Screwdriver
  3. Adjustable wrench
  4. Measuring tape

  6. Pliers
  7. Silicone caulk
  8. Shims
  9. Drill
  10. Hole saw
  11. Safety glasses
  12. Paint and brushes (optional)

Removing the Old Vanity

The first step in installing a new bathroom vanity is to remove the old one. This may sound like a daunting task, but with the right approach, it can be relatively straightforward. Here’s what you need to do:

  1. Turn off the water supply: Locate the shut-off valves under the sink and turn them clockwise to shut off the water supply. Don’t forget to test the faucets to ensure the water is fully turned off.

  2. Disconnect the plumbing: Use an adjustable wrench to disconnect the water supply lines from the faucet. Place a bucket or towel underneath to catch any water that may spill. Next, remove the P-trap by unscrewing the slip nuts and disconnect any other plumbing connections.

  3. Remove the countertop: If your old vanity has a countertop, you’ll need to remove it first. Use a screwdriver to loosen any screws or brackets holding it in place. Once the countertop is free, carefully lift it off the vanity base.

  4. Unscrew the vanity from the wall: Locate the screws securing the vanity to the wall and remove them using a screwdriver. It’s important to have someone assist you in holding the vanity to prevent any accidents during this step.

  5. Take out the old vanity: Once all the screws are removed, gently pull the old vanity away from the wall. Be cautious of any remaining plumbing connections that may still be attached.

Preparing for the New Vanity

Now that the old vanity is out of the way, it’s time to prepare for the installation of the new one. This involves measuring, leveling, and making any necessary adjustments. Follow these steps:

  1. Measure the space: Use a measuring tape to determine the dimensions of the space where the new vanity will be installed. Be sure to measure the width, height, and depth accurately. This information will help you choose the right-sized vanity for your bathroom.

  2. Level the floor: If your bathroom floor is not level, you may need to use shims to ensure the new vanity sits evenly. Place the shims under the vanity base, adjusting them until the vanity is level in all directions.

  3. Locate the wall studs: Use a stud finder to locate the wall studs where the new vanity will be mounted. This will ensure that the vanity is securely attached to the wall.

  4. Make any necessary plumbing adjustments: If the plumbing connections in your bathroom do not align with the new vanity, you may need to make some adjustments. This could involve extending or shortening the water supply lines or repositioning the drain pipe.

Installing the New Vanity

With the preparation work complete, it’s time to install the new bathroom vanity. Follow these steps for a successful installation:

  1. Position the vanity: Carefully place the new vanity in its designated spot, ensuring that it is flush against the wall. Use a level to make sure it is straight and adjust the shims if necessary.

  2. Secure the vanity to the wall: Once the vanity is in position, use a drill to screw it into the wall studs. Be sure to use the appropriate screws for your wall type to ensure a secure attachment.

  3. Connect the plumbing: Reconnect the water supply lines to the faucet, making sure to tighten the connections with an adjustable wrench. Attach the P-trap and any other plumbing connections, ensuring they are snug but not overtightened.

  4. Install the countertop: If your new vanity includes a countertop, carefully place it on top of the vanity base. Use a level to ensure it is even and make any adjustments as needed. Secure the countertop to the vanity using screws or brackets, following the manufacturer’s instructions.

  5. Seal the edges: To prevent water damage, apply a bead of silicone caulk along the edges of the countertop where it meets the walls. Smooth the caulk with your finger or a caulk smoothing tool for a clean finish.

  6. Optional: Paint and touch-up: If desired, you can paint the walls surrounding the new vanity or touch up any existing paint to complete the fresh look. Use painter’s tape to protect the vanity and apply paint using a brush or roller. Allow the paint to dry before removing the tape.
