More than likely, there will come a time where you need to replace bathroom sink fixtures. Fortunately, this work is not complicated. With a little information on your side, removing an old faucet is something you can accomplish yourself.

Choosing a Faucet

If your task involves completely replacing a faucet, consider the make, model, and style of the faucet you’d like to install. The range of choices can be astounding. For instance, inexpensive models are comprised mainly of plastic, whereas those that include a lot of brass are on the pricey side. A smart purchase is a more expensive unit that includes high quality parts. These parts will be easier to replace in the future; the better brands also come with warranties. Inquire about warranties when purchasing a faucet.

Step 1 - Turn Water Off

Always stop the water flow before commencing. You can do so at the main water valve, or you can shut off the pair of valves directly beneath the faucet. After doing so, open the faucet and let it drain to relieve pressure.

Step 2 - Detach Water Supply Lines

Now it’s time to detach the water supply lines. If you don’t intend to replace these lines, detach them only from the faucet. If you plan to replace them, detach them only from the shutoff valve.

Step 3 - Detach Faucet From the Sink

You should be aware of the 2 ways faucets are mounted. If it’s a bottom mounted faucet, it is removed from above. The handles and escutcheons need to be detached from the nuts securing the faucet. Top mounted faucets are attached with nuts that can be located beneath the sink; therefore, they are removed from above. Use a set of water pump pliers to remove these nuts.


If the sink is old, the nuts might be corroded or rusted; therefore, consider applying penetrating oil before you detach the nuts. There may be some grime buildup visible on the sink after the faucet has been removed. If so, clean it and prepare it for the new faucet. Water and vinegar, in a 50-50 solution, usually removes the grime. You might also need to scrub using a scouring pad or razor blade.
