How to replace a kitchen sink or bathroom lavatory faucet

The procedure to replace a kitchen sink faucet and a bathroom lavatory faucet is basically the same. Kitchen sink faucets are generally bigger in size and sometimes include a sprayer consisting of a push button handle or trigger and an aerator. The working area for replacement in a kitchen sink which is under the countertop cabinet is wider and thus a little bit easier to maneuver and work with the tools. Some bathroom lavatory faucet models have a pop-up drain assembly which is an additional component to install but is optional.

If you call a plumber to replace your leaking, broken, or defective kitchen sink faucet or bathroom lavatory faucet, you might be charged a considerable amount of money. When your plumber does the job on a Sunday or holiday, extra charges may apply and would add up to your expense and cost of labor. On the other hand, if you have a little experience with plumbing or mechanical repairs, don't worry, as long as you have the right tools, understand basic repairing safety, do some research and read instruction manuals, you can replace your kitchen or washroom faucet by yourself alone.

In the following steps below, I tried to use clear, simple, and easy to understand procedures/instructions for the benefit of do-it-yourself (DIY) and home improvement replacement and repair practitioners and readers. I also included pictures to help visualize, better understand and correctly follow the instructions.
