There’s no need to a call a plumber to change the lavatory faucets. Even a novice do-it-yourselfer should be able to get the job done in an hour or two. Limited access can make plumbing work difficult and uncomfortable, so open up the workspace around the vanity as much as possible to give you room to move around.Installing a new faucet does not require specialized tools. Before you begin, make sure the new faucet is compatible with your lavatory basin by verifying the number of mounting holes and the centre-to-centre distance.

Before Assembly

CHOOSE THE CORRECT FAUCET

Verify the number of holes on your lavatory basin or vanity before you choose a faucet. A standard lavatory basin will have between one and four holes. Faucets require one to three holes depending on the model. Even if it is possible to drill the lavatory basin in order to add new accessories, such as soap dispenser, it is preferable to replace the basin because of the difficulty in drilling certain materials.

Measure the center-to-center distance separating the two mounting holes at the back of the lavatory basin. The center-to-center distance must be the same for the new faucet. Since these are standard measurements, the distance should be either 4” or 8”.

INSTALLATION

Be sure to wear safety glasses when you’re working under the lavatory basin or vanity.

Turn off the water supply using the valves under the vanity. If you don’t have shutoff valves, shut off the water main, usually located in the basement. Drain the pipes and collect the water by opening the siphon under the sink.

If you are also replacing the lavatory basin, it is much simpler to install the faucet before you install the basin, then you’ll just have to make the connections.
