Easy DIY: How to Change a Bathroom Faucet

Replacing a bathroom faucet tutorial

When we moved into our house, we started noticing the things that you never notice during the initial viewing and the walk-through–scuffed corners, builder-grade materials, and shower grossness that you don’t see until you are actually taking a shower.

Well, one area that was really bothering us (read: Sean) was the master bathroom sink area. The faucets were small, ugly chrome and had such short spouts that Sean couldn’t really fit his hands underneath to wash them. Ew. Boys need clean hands, y’all. So, we made a trip to Lowe’s to look at faucets that had long enough spouts that could fit man hands underneath.

How To Change A Bathroom Faucet

*NOTE* Read the directions on the faucet you purchase. For example, some of the resources we found suggest using plumber’s putty. However, the directions on the particular faucet we bought discourages that since the putty is oil-based and can ruin some of the plastic parts on that particular piece of hardware.

Tools You’ll Need (you can find this on the back of the new faucet’s box, too):

  • Large bowl to catch excess water
  • Towels
  • Adjustable basin wrench (we found one for $20 at Lowe’s)
  • Adjustable wrench
  • Other tools/sealants as recommended by the new faucet’s instructions


1. First, TURN OFF THE WATER! Then turn on the faucet you’re replacing to try to get and excess water out of the pipes.

2. Place your bowl under your bathroom cabinet, under the U-shaped tube that connects your bathroom sink to the drain in the wall. Unscrew the caps that connect this U-shaped tube to the sink & drain. Be careful! Water will spill out of this!

3. The next step is to remove the drain pop-up (the thing that opens and closes the drain). You may need a strong person or a wrench depending on how tight this is screwed in. There will be goop in there if it’s an older sink fixture. Prepare to gag.

4. Turn off the hot & cold tubes at the bottom where they connect to the lines. Turn all the way to the right (righty tighty, lefty loosey). Then disconnect them with an adjustable wrench.

5. Next, use your basin wrench to remove the water input tubes that connect to the old faucet (the one you’re replacing).

6. Once your mounting nuts (hee hee) are removed, you should be able to lift the old faucet off the sink. You’ll want to clean underneath it since there will be residue/junks under there. There also might be gunk in the drain area. I’d clean that up too. Gross.

7. Now we’re at the fun part! Putting the new faucet on! Hooray. Line it up evenly.

8. Under the sink, screw in your two mounting nuts to tighten the faucet onto the counter/sink. Make sure it’s still aligned! Then tighten it even more with your basin wrench.

9. Now you can reconnect the hot and cold water supplies. Hand tighten the tubes at first, then secure even more with a basin wrench (see? it’s a handy tool for this project!)

10. Now, reconnect the supply hoses at the base of the water supply. Use an adjustable wrench to tighten beyond hand-tightening.

11. Now you install the pop-up drain. Make sure to follow the directions for your faucet. Ours had specific directions for which way the drain should face and how to position it.

12. Then tighten the nut underneath the drain to secure it to the sink (use putty or sealant according to your new faucet’s directions).

13. Based on your faucet model, install the drain pop up in back of the drain pop-up tube. Ours was a screw-in model with a little pop-in drain plug in the back. It looks like this one from the video is just a screw-in model. Again, use your faucet’s installation instructions on this part to make sure it’s done correctly.

14. From there, reconnect the U-shaped tube that you removed from the beginning, and tighten securely with am adjustable wrench. Be careful not to tightening anything too much that it cracks!

15. Turn the water supply back on, and run the faucet to check for leaks! Have towels handy just in case. If there are leaks, locate where the dripping is coming from and go back to that step to tighten or realign the faucet.

Happy fauceting!
