Step 1: Turn Off the Water Supply

Locate the shut-off valves for the hot and cold water supply lines beneath your existing vanity. Turn them clockwise until they stop completely, shutting off the water flow to the sink. Use a bucket to catch any residual water that drains from the pipes. 

Step 2: Disconnect the Plumbing Sink Drain 

Underneath the sink, loosen the nuts that secure the drainpipe to the P-trap (the U-shaped pipe). Once loose, detach the drainpipe and place it in the bucket to catch any remaining water. Water Supply Lines: Using an adjustable wrench, carefully disconnect the hot and cold water supply lines from the shut-off valves and the faucet. Be prepared for some water to drain – place the bucket underneath to collect it. 

Step 3: Dismantle Existing Vanity Mirror and Hardware

Begin by removing any fixtures attached to the vanity, such as the mirror, light fixtures, or towel racks. Carefully place them aside for potential reuse or proper disposal. 

Disconnect Cabinetry: Locate the screws or bolts securing the vanity to the wall. Unscrew or unbolt them carefully, ensuring someone supports the vanity to prevent it from falling forward. 

Plumbing Access: Depending on your vanity design, there might be a panel at the back for plumbing access. Remove this panel if present, providing easier access to the disconnected pipes. 

Step 4: Remove Old Vanity

Once all connections are severed and the vanity is disconnected from the wall, carefully pull it away from the wall studs. Have a helper assist you if the vanity is heavy. 

Step 5: Prep the Space

If you're not replacing the flooring or wall tiles, use painter's tape to protect them from potential scratches or debris during the installation process. 

Step 6: Install the New Vanity 

Position your new vanity: Carefully maneuver the new vanity into place, ensuring proper alignment with the wall and maintaining a level position. 

Secure the Vanity: Using screws or bolts appropriate for your wall studs, securely fasten the vanity to the wall at designated locations. Double-check for levelness throughout the installation process.

Step 7: Connect the Plumbing Faucet Installation

Install the new faucet onto the designated holes in the countertop, following the manufacturer's instructions. Ensure all connections are secure and watertight. Water Supply Lines: Using new shutoff valves and following local plumbing codes, connect the hot and cold water supply lines to the new faucet. Tighten the connections securely with an adjustable wrench. Drainpipe Reassembly: Reassemble the drainpipe using the new P-trap (if included with the vanity) and following the manufacturer's instructions. Ensure all connections are secure and leak-proof. 

Step 8: Test for Leaks 

Once all plumbing connections are complete, turn on the shut-off valves beneath the sink to allow water flow. Carefully inspect all connections for leaks. Tighten any loose connections or use plumber's putty (if applicable) to address minor leaks. 

Step 9: Install Vanity Top

If you're replacing the bathroom vanity countertop as well, carefully position it onto the new vanity, ensuring proper alignment with the backsplash and sink cutout. Follow the countertop manufacturer's recommendations for securing it to the vanity base. 

Step 10: Finishing Touches & Caulking

Apply a bead of silicone caulk around the perimeter of the countertop where it meets the wall. Smooth the caulk with a wet finger for a professional finish. Install Hardware: Reinstall the mirror, towel racks, or any other fixtures.
