Step By Step Guide

You might be hesitant to change your faucet because you are worried that it might be a hassle. Well, surprisingly it is very easy to do.

Whether you want to give your bathroom a fresh makeover or you just simply want to put in a new fancy faucet because your old one got rusty, we got you covered. 

Tools to prepare

Tools to prepare :

  • Single handle faucet
  • Deck plate
  • Teflon tape
  • Wrench
  • Silicone sealant
  • A Bucket
  • A towel
  • Screwdriver
  • Flashlight

Step 1: Prepare your tools

Make sure that you have all the necessary tools before starting the work and check the type of your faucet since not all can be removed simply with a wrench.

You may use other tools like screwdrivers if your sink has bolts. Depending on the type of faucet you wish to install, the procedure for installing a new bathroom faucet handle can also differ. 

You can find your model's user manual online if your new faucet did not come with any.

Step 2: Turn off your water supply

Do not forget to turn off your water supply before unscrewing all those nuts and bolts. Make sure it is completely shut down. You can turn off your water supply by simply twisting clockwise or counterclockwise, depending on your shut-off valve.

Step 3: Unscrew waterlines

Now that your water supply is completely cut off, start unscrewing some nuts from below and above if there are any.

Using your wrench, make sure to only unscrew necessary parts, like the nuts connecting your water lines to your faucet and the nuts connecting your old faucet to your sink. You may need to exert more force and effort here. 

Unscrewing those nuts can be tough and tricky at the same time. Once you're done, carefully remove the old faucet. 

Step 4: Clean your area

We want to start with a clean canvas. Now that your old faucet that is filled with grime is removed, it is your chance to give your sink some cleaning.

Don't forget to wipe off the surface and the holes before placing your new faucet. We don't want your new faucet to look grimy.

Step 5: Cover extra holes

Once you are done cleaning, after removing your two-handle faucet, you will notice that there are extra holes. You may wonder how to hide them. Well, we can simply hide those with a deck plate. Make sure to get one just in case your store-bought faucet does not include one.

Install your deck plate, and ensure that the one you bought will be able to cover the holes that you need to hide. If you need to, you can use silicone sealant to keep your deck plate attached to the sink. 

Step 6: Place your new faucet

Place and install your new single-handle faucet. Make sure the water lines are connected to your faucet. Red denotes hot water, whereas blue denotes cold water, and that should help to put your deck plate is in place. 

Step 7: Align and assemble everything

After ensuring that your deck plate is centered and correctly aligned, place your new single-handle faucet into the hole. Ask for an extra helping hand if necessary to keep the faucet in place while securing the nuts from the bottom.

If you are having a hard time and can't see the valves below, you can use your flashlight. 

Step 8: Connect your water line 

Carefully connect the water lines from below after you are satisfied with the position of your new faucet. Check if the valves are all linked properly and secure the nuts back in their place. Make sure to screw it tight to avoid water leaking all over the place. 

You can use Teflon tape to prevent leaks just in case.

Step 9: Check your newly installed faucet

After all that hard work, now is the time to test your newly built faucet. Turn on your water supply. Check the water pressure. Check if the handle corresponds correctly with the hot and cold options.

Test your faucet handle if the amount of water coming out is just right. 

Check below if there are any leaks. Run your tap for a bit to rinse off excess dirt, this will help to clean your faucet as well. Do not forget to clean your area.
