Vanity with faucet

Insert the Faucet Into the Vanity Top

Start by attaching the mounting brackets to threaded rods on each side of the faucet. Fasten the retaining nuts, leaving a few threads exposed. Place the plastic gasket on top of the vanity top ​and over the sink holes, making sure to correctly orient the gasket.

Carefully insert the faucet body and threaded rods into the faucet holes by angling the mounting brackets so they can fit through the mounting holes. Ensure flush and proper alignment of the faucet onto the plastic gasket.

Fasten the Faucet to the Vanity Top

Secure the faucet to the vanity top by tightening the mounting brackets flush against the underside of the top, making sure the bracket spans the faucet hole completely. You can use an adjustable or closed-end wrench or a basin wrench if space is limited.

Attach Water Supply Lines

Once the faucet is attached to the top, attach the hot and cold water supply lines to the faucet. The supply lines will have a rubber washer on one end. That is the end that attaches to the faucet hot/cold water lines. Snug the connection but do not over-tighten.

If you are executing this project with the countertop off, be sure the water lines come up through the middle of the vanity cabinet.

Attach and Tighten Sink Drain Flange

Attach the sink drain flange to the vanity sink by sealing the underside of the drain flange with a waterproofing sealant. You can use plumber's putty. An alternative to plumber's putty is to use clear silicone caulk around the perimeter of the drain.

Fasten the drain flange to the sink by securely tightening the large retaining nut to the drain flange tailpiece on the underside of the counter.

Clean Up Residual Sealant

Flip the top over (if you're working with an unattached counter) and clean any putty or caulk residue which has oozed out from under the drain flange with rubbing alcohol.

Attach O-Ring and Pop-Up Drain Tailpiece

Place the rubber O-ring onto the drain flange tailpiece. It will seal the connection to the pop-up tailpiece.

Tighten the pop-up tailpiece with the pop-up opening facing the rear.

Insert Pop-Up Ball/Pivot Rod

Insert the pop-up ball and pivot rod into the pop-up tailpiece. Make sure the pivot rod is inserted into the little hole at the bottom of the pop-up drain piece. Replace the pivot rod retaining nut and finger tighten.

Install Drain Lift Rod

The pop-up drain is controlled by a lift rod. There is a lift rod bracket that attaches to the lift rod with what is called a clevis bolt.

Drop the lift rod through the rod hole on the top of the faucet. Insert it into the flat bracket and temporarily secure it with the clevis bolt. The final location of the clevis bolt attachment will be determined with the final adjustment of the pop-up drain.

Secure the lift rod to the pop-up drain pivot rod with the spring clamp. It gets installed first through the pivot rod, then through the lift rod, then again through the pivot rod.

Adjust Pop-Up to 1/2-Inch Action

Adjust the height of the pop-up drain so it is raised 1/2 inch when the lift rod is fully depressed and is sealed against the sink drain flange when the lift rod is raised. You may have to alter the location of the clevis bolt and/or the lift rod clip to get the proper action for the pop-up drain.

Install Assembled Sink/Faucet Into Vanity

With the faucet installed into the sink, install the vanity top onto the bathroom vanity.
