How to Install a Bathroom Sink

Installing a bathroom sink is a relatively simple plumbing project that can be completed in a few hours. With a few basic tools and materials, you can save yourself the cost of hiring a plumber. Here are the steps on how to install a bathroom sink:

Step 1: Gather your tools and materials

Adjustable wrench
Basin wrench
Phillips head screwdriver
Flat head screwdriver
Plumber's putty
Teflon tape
New sink
New faucet
Pop-up drain assembly

Step 2: Turn off the water supply

Locate the water supply valves under the sink and turn them off. Open the faucet to release any remaining water in the lines.

Step 3: Remove the old sink

Use the adjustable wrench to loosen the nuts that hold the water supply lines to the faucet. Disconnect the water supply lines and the drain line from the sink. Carefully lift the sink out of place.

Step 4: Clean the countertop

Use a damp cloth to clean the countertop where the new sink will be installed. Remove any old caulk or debris.

Step 5: Apply plumber's putty

Roll out a rope of plumber's putty and apply it to the underside of the new sink. The putty will help to seal the sink to the countertop and prevent leaks.

Step 6: Set the new sink

Carefully set the new sink into place on the countertop. Align the sink with the drain hole and press down firmly to seat the putty.

Step 7: Connect the water supply lines

Wrap Teflon tape around the threads of the water supply lines. Connect the water supply lines to the faucet and tighten the nuts using the adjustable wrench.

Step 8: Connect the drain line

Apply plumber's putty to the threads of the pop-up drain assembly. Insert the drain assembly into the drain hole and tighten the nut.

Step 9: Install the faucet

Insert the faucet into the holes in the sink. From underneath the sink, attach the washers and nuts to the faucet and tighten them using the basin wrench.

Step 10: Turn on the water supply

Slowly turn on the water supply valves and check for leaks. If you find any leaks, tighten the nuts or adjust the putty.

Step 11: Caulk the sink

Apply a bead of caulk around the edge of the sink where it meets the countertop. Smooth out the caulk using your finger or a damp cloth.

Your new bathroom sink is now installed and ready to use. Congratulations!
