How to replace a bathroom sink

Bathroom Sink Replacement 101

After years of use bathroom sinks often become chipped, stained or scratched. You may want to install a new sink to enhance the look of your bathroom and create a clean, new look. Replacing a bathroom washbasin may take some time, but it is not difficult to accomplish, and could revitalize the entire bathroom.

Step 1:

Measure the dimensions of your old bathroom sink with a measuring tape. When installing a new sink, you need one that will fit in the old countertop. Be sure to take accurate measurements. Write down the length, depth and width of the sink. Also write down the length and width of the countertop.

Step 2:

Buy a new washbasin. When buying your new washbasin bring the measurements of the old sink and countertop with you to make sure you purchase the right size before putting in a bathroom sink

Step 3:

Turn off the water to the sink. The shut off handle is most often located under the sink. When replacing a bathroom washbasin, you want to test the faucets to make sure the water is completely off



Step 4:

Place a bucket underneath the P-trap  When installing a new sink, you will first have to remove the drainage pipe .

• Loosen the bolts that attach the P-trap to the bottom of the sink using channel lock pliers.
• Hang the P-trap over the bucket,  pulling it, carefully, from the sink.

        

Step 5:
Un-fasten the cold and hot water hoses from the faucet with a crescent wrench. You will have to get under the sink to remove the hardware.  It is not difficult but may take a few minutes.

Step 6:

With a screwdriver remove the clips underneath the sink that attach it to the countertop .

Step 7:

Using a utility knife, cut out any sealant or putty between the countertop and the sink



Step 8:

Lift out the old sink from the counter. You will need a smooth surface for your new sink, so clean the countertop off, removing any residual silicon.



Step 9:

If you plan to use the faucet and drain from the old sink remove it now.

Step 10:

Install the old drain and faucet on the new sink. To install a new sink, you need to seal the hardware. Make sure to apply a bead of silicone caulk to the faucet and drain base before putting them into your new sink. If you bought a new faucet instead of using the old one, follow the directions that came with the new one.

Step 11:

Apply silicone caulk to the underside of the washbasin's rim before putting in a bathroom sink. Carefully lower the sink into the hole in the countertop. Firmly push the washbasin into place and wipe off any excess silicone with a paper towel.

Step 12:

Attach the sink to the countertop with fastener clips from beneath the counter. You will need to make sure it is secure.





Step 13:

Using the crescent wrench reconnect the water lines. Then reconnect the P-trap underneath the sink with channel lock pliers.  Tighten the valves but make sure they are not too tight.

• Turn the water valves back on. Keep the bucket under the P-trap while you test the sink for any leaks. Sometimes, putting in a bathroom sink will creates water leakage.
• Twist on the hot water and then the cold water. If there is a leak, shut off the water and re-install the connections. Than wrap plumber's tape around the stem of the hose to stop the leaks.





Step 14:

Let the bathroom sink sit overnight.  That's it you're done!
