Can You Use Kitchen Faucet In Bathroom?

It’s possible to use a kitchen faucet in the bathroom. But keep in mind that kitchen and bathroom faucets often have different features and properties.

Understanding those dissimilarities will help you gain better knowledge on how to set up and use your preferred kitchen faucet in your bathroom. Some of these distinctions are:


Bathroom sinks are generally smaller than their kitchen counterparts. The typical bathroom sink size ranges from 16 to 24 inches. On the other hand, kitchen sinks often have sizes that go from 25 to 36 inches.

The dissimilarities in sizes between bathroom and kitchen sinks can make the faucet installation process involve more steps than usual. For instance, some kitchen faucet models have 17.3-inch heights that should have relatively no problem fitting into kitchen sinks.

However, fitting the same faucets in smaller bathroom sinks can cause some installation issues. It’s because of the incompatibility with the dimensions that these problems arise.

Installation Process

Installation procedures between kitchen and bathroom faucets are also quite different. Many kitchen faucet installations typically only require a few steps, which makes it fairly easy for DIY beginners. However, assembling a bathroom faucet may require sizing requirements, which might become complicated.

Here’s a quick view of the installation procedures for kitchen and bathroom faucets. The information detailed below will give you a general idea about the differences between these fixtures' setup processes.

Installing a Bathroom Faucet

Assuming that the plumbing line is already in place, the first step to installing the faucet is to turn off the water flow going to the bathroom. Make sure to turn off both hot and cold water lines before continuing this job. After ensuring that you stopped the water going to the bathroom, here are the rest of the steps:

What You’ll Need
  • Tupperware container
  • Basin wrench
  • Pliers
  • Bathroom faucet kit
  • Silicone or plumber’s putty
Step-by-Step Guide
  1. Place the Tupperware container underneath the P-trap. Then, remove the P-trap below the sink while ensuring to catch the excess water that comes out with the container.
  2. Slide the basin wrench up the supply line until you reach the nut that connects the line to the sink. Turn the nut clockwise with the wrench to remove the attachment.
  3. Use a pair of pliers to unscrew the drain from the bathroom sink.

Although both bathroom and kitchen faucets share the same purpose of providing water, these two plumbing fixtures often have distinguishing features that set them apart. For instance, kitchen faucets often fall under different types like:

  • Pull-outs: Generally has a detachable head to provide better reach.
  • Pull-downs: Offers enhanced flow or spray control to allow users to reach corners of the sink.
  • Pot fillers: Often installed at the backsplash to help fill pots and other containers with water.

On the other hand, the various types of bathroom faucets include the following:

  • Bridge: Typically has a "bridge" design that connects the levers and the faucet with one branch.
  • Center: Also called the center set, this type often has a handle mounted on the faucet.
  • Spread-fit: Commonly sits below a countertop or vanity sink deck.
