If you know how to remove a bathroom faucet and drain, the procedure is insanely easy for you and vice versa. If you are new to this, reading this post will make the work easy for you too. Check out the tools that you need to get started!

  • Penetrating oil
  • Channel lock pliers
  • Putty Knife
  • Adjustable wrench
  • Damp cloth
  • A bucket
  • An old towel

If you have these requirements in place, we can get started down here! In this case, I will give you a separate procedure for a single handle faucet, a double handle faucet, and the drain.

Removing A Single Handle Bathroom Faucet

  • Under your sink, clear all the space to allow room for placing your empty bucket. The bucket will help to avoid water spillages on the bathroom floor. Any accidental spillages will be dried by use of the old towel.
  • In the next step, turn off the water supply lines from the main meter or valve.
  • After you realize that there is no spillage, start loosening the nut under your bathroom sink and slide the strap. From the back of the tailpiece, you can remove the horizontal rod after unscrewing from the pivot area.
  • Disconnect the water supply lines joining to the bathroom faucet using an adjustable wrench.
  • Use a wrench to unscrew a nut underneath the bathroom sink which grips the faucet in place. Sometimes, the bolt might not be able to budge, but you can apply penetrating oil and allow some hours before proceeding.
  • After you can remove the nut, you can easily remove the faucet. The faucet might be still held on the countertop, wall, or sink. If this is the case, break the seal by use of a putty knife; you can now remove the old faucet effortlessly. After that, use a damp cloth to wipe and clean the surface.

Removing A Double Handle Bathroom Faucet

  • Just as it was the case for a single handle bathroom faucet, start by clearing the underneath of your sink and placing an empty bucket to help collect any spills. You can remove any unexpected spills by use of the old towel.
  • Some faucets have separate handles for cold and hot water. If this is the case, you can disconnect the handles’ valves from the faucet spout by unscrewing the coupling nuts. After that, you can detach the two supply valves.
  • Underneath your sink, there are nuts which clutch the handles and spout in place; use a wrench to unscrew and remove them. Apply the penetrating oil if the bolts fail to dislodge and allow a few hours.
  • After removing the nuts, you can pull out the faucet. The faucet might still be firmly held due to the presence of putty. Use a putty knife in this case for breaking the seal; use the damp cloth to wipe and clean the surface. You can now remove the faucet.

Removing the Drain

  • Where the tailpiece enters the drain beneath the bathroom sink, use a pipe wrench to disconnect it.
  • At the bottom of the bathroom sink, there is a large; you need to use a channel lock pliers to unscrew it. Having done this, you can remove the gasket and the washer. Break the seal inside your bathroom sink by pushing up the tailpiece.
  • Finally, unscrew and remove the sections below and above the sink.
  • Having completed all this, you need to clean up the area before installing the new drain. Make sure that the area is clean before doing anything else.

Procedure # 2: How To Replace A Bathroom Faucet and Drain

In this final phase, these are the requirements for the procedure- plumbers tape, crescent wrench, and waterproof bathroom caulk.

  • Inspect that all the components of the new bathroom faucet and drain are available before starting the process.
  • Underneath your bathroom sink, connect water supply valve(s) with the hose(s). Remember, you are dealing with either a single handle or a double handle faucet in this case. Connecting the water supply valve and hose will require plumbers tape and crescent wrench. You need to wrap a layer of plumbers tape on the threads and secure the connection.
  • Next, attach the new bathroom faucet inserting it in its position. Use a crescent wrench to tighten the connection.
  • Installing the drain might seem complicated, but this is how it is quickly done. You will start by coating the base of the drain opening and setting it down into the underside hole of the bathroom sink using a waterproof caulk. Immediately after doing this, place a plastic washer, rubber washer, and plastic nut on the bottom of the newly set bathroom sink drain; secure the drain in place. Depending on the drain components that are available, you must have instructions alongside these components. These instructions have drawing and illustrations that can help you understand different parts and how they should be attached because there is no universal way to explain this. Look and follow the figures in the drawings and after that, secure all the parts correctly.
  • If there are no leaks detected after securing the connections, you’ve now successfully finished the process.
