Can A Kitchen Faucet Be Used In The Bathroom?

Kitchen faucets seem like an easy substitute for bathroom faucets because they both serve the same purpose in providing water for cleaning. However, can kitchen faucets be used as a substitute for the bathroom?

Yes, a kitchen faucet can be used in the bathroom. Holes for the water hose must fit the proper width, and the sink bowl must handle the amount of water output for a kitchen faucet to be used effectively as a bathroom substitute.

Kitchen sinks and bathroom vanities, however, are designed completely differently from one another. This article will look at why you shouldn’t use a kitchen faucet on the bathroom vanity.

Can A Kitchen Faucet Be Used In The Bathroom?

The short answer is yes, but there are a few things that you should take precautions about before making a purchasing decision. The holes for the water hoses must be fit for the bathroom faucet. Most of the time, the plumbing is different from the kitchen than it is for the bathroom. We recommend consulting with a plumber before actually making the call to use a kitchen faucet.

The bowl must be able to handle the drainage from the water output of the kitchen faucet hose. Bathroom faucets are often smaller and have smaller bowls to drain. This must be taken into consideration to avoid future plumbing issues.

The holes for bathroom vanities or often prefabricated to allow a standard structure for plumbers. It’s typically a 4-inch hole that is pre-drilled for easy plug and plays setup.

However, with kitchen faucets, the sinkholes are often drilled in different ways to allow single hose nozzles or multiple handles. This is the biggest issue with using kitchen faucets in the bathroom.

Why You Shouldn’t Use A Kitchen Faucet In The Bathroom

We recommend you avoid using a kitchen faucet for the bathroom for a few reasons.

First, it will look completely out of place. Kitchen faucets are typically hose-type faucets that disconnect from the holster to reach hard-to-clean places. Bathroom vanities will look awkward and out of place with a large head that protrudes over the sink’s bowl.

On top of the nozzle/hose, the handles are often spaced wider for kitchen faucets. This could look awkward, clunky, and especially noticeable for guests who hobby interior decorating.

Our last reason is there isn’t a need to. There are so many beautiful options for both nozzle and handle faucets that it’s almost entirely unnecessary to use a kitchen faucet as a sink option.

If you’re stuck finding examples, here are two fantastic options for bathroom sinks that will hopefully change your mind.

Bathroom Sink 2 handles

Our first pick a the PARLOS swivel spout 2 handle faucet. It’s a brushed nickel design and great for homeowners looking for a 2 handle system to distribute water to dirty hands.

The clean model and design are a fit for almost any bathroom style. The 3-hole mount with a 4-inch center-set fits with any bathroom vanity for easy installation.

If you’re looking for more of a single faucet drain, our second pick is the Delta single-handle bathroom faucet.

Designed to fit 3 holes, 4-inch configurations, this bathroom faucet is another clean option for any vanity.

Delta WaterSense faucets use 20% less water than the industry standard sinks, which helps in the long run for water consumption.

Do All Faucets Fit All Sinks?

All faucets do not fit every type of sink. Each type of faucet and sink is built for water use and water absorption. We’re going to cover two sinks, which are all directly related to the water output.

Also, these types of sinks are custom to the environment they will be in. Bathroom basins are often found within a cutout in a bathroom vanity. Kitchen sinks typically have their own cut out which is custom to the style of the kitchen.

We will show you two types of sinks and tell you why all faucets may not be the best match for all sinks.

Bathroom Basin

Bathroom Basin

A basin is a small bowl that can hold a small amount of water. This type of bowl is typically used for washing hands or faces. It not only drains at a slower rate, it typically has less water pouring out of the spout to go along with the slow absorption.

Basin’s are often found in small household bathrooms and can handle simple tasks such as brushing teeth, washing face, or a quick rinse.

Kitchen Sinks

Kitchen sinks

Kitchen sinks typically have bigger bowls that can hold stacked dishes and dirty silverware. There’s a bigger surface for kitchen sinks because of the amount of water that is dispersed. When washing dishes, it’s common to have the sink running on maximum output.

The maximum output will flood a small bathroom basin, which is it may not make sense to have a large kitchen faucet in a bathroom sink.

If you’re going to use a kitchen sink for the bathroom, we recommend making sure the water output matches the bowl catching the water. Obviously, too small of a bowl could result in flooding and water damage as it leaks.

Having a kitchen sink fit to match the water output of a bathroom basin may be tough. We recommend checking with your plumber to see if the hoses can be hooked up from the proper outpour of water.

It’s always better to be safe than sorry in this situation dealing with water from a faucet.


Kitchen faucets can be used as a bathroom faucet, but only if they meet the 3 holes, 4-inch regulations. We highly recommend against using a kitchen faucet due to the overwhelming number of options available for bathroom sinks.

Shopping for bathroom faucets is a chore in itself. It’s much easier to purchase a bathroom sink and not have to worry about returning a kitchen faucet if it doesn’t meet requirements, is too big, or is too big for the drain.
