Step 1: Make a Cutout in the Vanity

Position the vanity in the desired location to check for fit and placement.

Remove the doors and drawers from the vanity for easier installation.
Measure and mark the back of the vanity cabinet for the location of the sink drain. Cut a hole for the drain with a hole saw; Amy used a 3" hole saw to accommodate the 2-1/2" drain. Start the cutout from the back (outside) of the vanity, then finish the cut from the inside of the vanity. This will help avoid splintering the wood.

Position the vanity so the hole lines up with the sink drain.

Step 2: Center the Vanity

To center the vanity under the new bridge faucet, find and mark the center point between the hot and cold supply lines. Use a level to draw a plumb line down the wall from this mark.

Step 3: Position/Line Up the Cabinet

Measure and mark the center point on the cabinet. Position the cabinet against the wall, lining the center point of the cabinet up with the centerline on the wall. Make sure the drain hole still lines up with the sink drain.

Check the cabinet for level and plumb. Use shims as needed to level the cabinet.

Step 4: Drill the Pilot Holes

Drill small pilot holes through the back of the cabinet into the wall studs. Attach to the studs with screws.

Step 5: Dry-Fit the Cabinet

Dry-fit the countertop to the cabinet. To secure the countertop, raise the front edge and apply dime-sized dollops of silicone to the top of the cabinet. Lower the countertop into place and allow the silicone to cure.

Step 6: Remove the Cabinet Doors

Remove the doors from the additional storage cabinets. This will help protect them from damage and also will free up space for the work.

Step 7: Drill Holes to Fit the Electrical Box

One of the cabinets will sit in front of a hard-wired electrical box – handy for plugging in hair dryers and other small appliances. Measure the position of the electrical box on the wall, then transfer this measurement to the back of the correct cabinet. Drill a hole inside the marks large enough to fit the jigsaw blade (Image 1), then cut out the box shape with the jigsaw (Image 2).

Safety Alert: Always wear safety glasses and use caution when working with power tools such as a drill or jigsaw.

Step 8: Secure the Cabinet to the Wall Studs

Locate the studs that will sit behind the cabinet and transfer those measurements to the inside of the cabinet. Drill a pilot hole, then secure the cabinet to the wall studs with cabinet screws.

Use the same procedure to install the other cabinet.

Re-attach the doors and insert the drawers.
