How to Hook Up Plumbing for a Bathroom Sink

Installing a bathroom sink is a common plumbing project that can be completed in a few hours with the right tools and materials. By following these steps, you can ensure that your new sink is properly connected to the water supply and drain.

Materials You'll Need

Before you begin, gather the following materials:

Bathroom sink
Faucet
Drain assembly
P-trap
Supply lines
Wrench
Pliers
Caulk
Tape measure
Level

Step 1: Turn Off the Water Supply

Before you start working on the plumbing, it is important to turn off the water supply to the bathroom. Locate the shut-off valves under the sink and turn them clockwise to close them.

Step 2: Install the Drain Assembly

Place the drain assembly in the drain hole in the sink. The assembly should fit snugly and should have a rubber gasket to create a watertight seal. Tighten the drain assembly by hand, then use pliers to fully tighten it.

Step 3: Install the P-Trap

Attach the P-trap to the drain assembly. The P-trap is a curved pipe that helps to prevent sewer gases from entering the bathroom. Tighten the nuts on the P-trap by hand, then use pliers to fully tighten them.

Step 4: Connect the Supply Lines

Connect the supply lines to the faucet. The supply lines are flexible hoses that bring hot and cold water to the faucet. Tighten the nuts on the supply lines by hand, then use a wrench to fully tighten them.

Step 5: Install the Faucet

Place the faucet in the hole in the sink. The faucet should fit snugly and should have a rubber gasket to create a watertight seal. Tighten the faucet by hand, then use a wrench to fully tighten it.

Step 6: Caulk the Sink

Apply a bead of caulk around the edge of the sink where it meets the countertop. The caulk will help to create a watertight seal and prevent leaks.

Step 7: Turn On the Water Supply

Once all of the connections are made, turn on the water supply to the bathroom. Check for any leaks at the joints. If you find any leaks, tighten the nuts or bolts until the leak stops.

Step 8: Level the Sink

Use a level to check if the sink is level. If it is not level, adjust the height of the legs on the bottom of the sink until it is level.

Congratulations!

You have now successfully installed your new bathroom sink. By following these steps, you can ensure that your sink is properly connected to the water supply and drain, and that it is free of leaks.
