How To Install A Bathroom Sink

Installing a bathroom sink is a relatively simple project that can be completed in a few hours. By following these step-by-step instructions, you can save yourself the cost of hiring a plumber.

Tools and Materials You'll Need

Basin wrench
Plumber's putty
Teflon tape
Putty knife
Faucet wrench
Adjustable wrench
Caulk gun
Caulk
Level

Step 1: Remove the Old Sink

Turn off the water supply to the sink. Using a basin wrench, loosen the nuts that hold the faucet in place. Remove the faucet and set it aside. Next, use a putty knife to remove the old plumber's putty from around the sink. Finally, carefully lift the old sink out of the vanity.

Step 2: Prepare the New Sink

Apply a bead of plumber's putty to the underside of the new sink. The putty should be about 1/4 inch thick and should form a continuous seal around the edge of the sink. Next, wrap the threads of the faucet with Teflon tape. This will help to prevent leaks.

Step 3: Install the New Sink

Carefully lift the new sink into the vanity. Align the sink with the drain hole and gently press it into place. Tighten the nuts that hold the faucet in place. Use a level to make sure that the sink is level.

Step 4: Install the Drain

Apply a bead of plumber's putty to the underside of the drain flange. The putty should be about 1/4 inch thick and should form a continuous seal around the edge of the flange. Carefully insert the drain flange into the drain hole and tighten the nut. Use a level to make sure that the drain is level.

Step 5: Install the Faucet

Insert the faucet into the holes in the sink. Tighten the nuts that hold the faucet in place. Use a faucet wrench to tighten the nuts until they are snug.

Step 6: Apply Caulk

Apply a bead of caulk around the edge of the sink where it meets the vanity. The caulk should be about 1/4 inch thick and should form a continuous seal around the edge of the sink. Smooth the caulk with your finger or a caulk tool.

Step 7: Turn on the Water Supply

Turn on the water supply to the sink and check for leaks. If there are any leaks, tighten the nuts that hold the faucet and drain in place until the leaks stop.
