How to Install a Countertop Bathroom Sink

Installing a countertop bathroom sink is a relatively easy project that can be completed in a few hours. With a little planning and preparation, you can save yourself the cost of hiring a plumber. Here are the steps on how to install a countertop bathroom sink:

Step 1: Gather Your Materials

Before you begin, you will need to gather the following materials:

Countertop bathroom sink
Faucet
Drain assembly
P-trap
Sink strainer
Faucet supply lines
Pipe wrench
Wrench
Screwdriver
Level
Measuring tape
Pencil
Caulk
Painter's tape

Step 2: Prepare the Countertop

Begin by measuring the countertop to determine the center point. Mark the center point with a pencil. Once you have the center point, position the sink over the hole and trace the outline of the sink. Use a utility knife to cut the hole in the countertop.

Step 3: Install the Drain Assembly

Place the drain assembly into the drain hole from the bottom of the sink. Hand-tighten the drain assembly until it is snug. Do not overtighten, or the drain assembly could break.

Step 4: Install the Faucet

Place the faucet in the hole in the sink and hand-tighten the nuts until they are snug. Do not overtighten, or you could damage the sink.

Step 5: Install the Faucet Supply Lines

Connect the faucet supply lines to the water supply valves under the sink. Use the pipe wrench to tighten the connections.

Step 6: Install the P-Trap

Connect the P-trap to the drain assembly and the sink drain. Use the pipe wrench to tighten the connections.

Step 7: Install the Sink Strainer

Place the sink strainer in the drain hole in the sink. Press down on the strainer until it is seated properly.

Step 8: Caulk the Sink

Apply a bead of caulk around the edge of the sink where it meets the countertop. Use the painter's tape to protect the countertop from the caulk. Allow the caulk to dry completely before using the sink.
