How To Change Out A Bathroom Sink

Whether you're updating the look of your bathroom or replacing a damaged sink, changing out a bathroom sink is a relatively simple plumbing project that can be completed in a few hours. Here's a step-by-step guide to help you through the process:

Gather Your Tools and Materials

Before you start, gather all the tools and materials you'll need:

New bathroom sink
Wrench
Pliers
Plumber's putty
Caulk gun
Caulk
Bucket or basin

Turn Off the Water Supply

The first step is to turn off the water supply to your bathroom sink. Locate the shut-off valves under the sink and turn them clockwise until the water is completely off. Once the water is off, open the faucet to release any remaining water in the lines.

Disconnect the Water Lines

Using a wrench, disconnect the water supply lines from the faucet. Be careful not to damage the lines or the faucet. If the lines are old or corroded, you may need to replace them.

Remove the Old Sink

Once the water lines are disconnected, you can remove the old sink. Carefully lift the sink up and off the countertop. If the sink is heavy, you may need to have someone help you. Once the sink is removed, clean the countertop and the area around the drain.

Apply Plumber's Putty

Before installing the new sink, apply a bead of plumber's putty around the drain hole on the underside of the sink. This will help to create a watertight seal.

Install the New Sink

Carefully place the new sink into the opening on the countertop. Make sure that the sink is level and that the drain hole is aligned with the drain in the countertop.

Tighten the Mounting Bolts

Once the sink is in place, tighten the mounting bolts that hold the sink to the countertop. Do not overtighten the bolts, as this could crack the sink.

Reconnect the Water Lines

Using a wrench, reconnect the water supply lines to the faucet. Make sure that the connections are tight, but do not overtighten them.

Turn on the Water Supply

Turn on the water supply valves under the sink. Check for leaks around the faucet and the drain. If you find any leaks, tighten the connections or replace the washers.

Caulk Around the Sink

Apply a bead of caulk around the edge of the sink where it meets the countertop. This will help to prevent water from seeping into the gap and damaging the countertop.
