Does The Kitchen Sink Have To Be Under A Window?

Thinking about renovations is the easy part. Now, it's time to put your ideas into action. One area you'll need help with is the kitchen sink. Does it need to be under a window? If that's what you're wondering, you're in luck. We looked into this topic, and we have an answer.

There's no rule set in stone to install a kitchen sink under a window. It's all up to personal preference. However, some would argue it's more practical to do so. For example, placing a kitchen sink under a window will make plumbing installation and access easier. 

So, what exactly are you sacrificing if you want to place the kitchen sink somewhere else? Additionally, how much would it cost to move it? These are some of the questions we'll cover at length in this post. If you'd like to learn more, keep reading ahead.

Kitchen Sink Placement Considerations

Of course, before you start your project, it's a good idea to take a look at the considerations for each position. Let's begin by going over why it might be a good idea to place a kitchen sink under a window. 

Having The Kitchen Sink Under A Window

The first aspect you want to consider is space. Though, this will depend on how often you're washing a large number of dishes or if you're cleaning large items. 

If you place a sink away from a window, there are two possibilities for the wall it will be facing. In the first scenario, you might want to install overhead cabinets. Depending on how much space you have on the walls and how big the cabinets will be, it might interfere with the workflow.

For the second scenario, there won't be anything on the wall. If you have limited room, it will be a waste of wall space. Thus, it leaves you in a predicament if you value your space.

Since you'll most likely want a window installed somewhere in the kitchen—and you might not want to sacrifice wall space—a kitchen sink under a window makes sense. This situation opens up opportunities for things you can install on the wall the kitchen sink would've been facing.


Now, let's address plumbing. As plumbing professionals suggest, installing a kitchen sink under a window will make plumbing easier to install and access. But how exactly does it do that?

The waste plumbing usually runs through an external wall. Since the window is an outside wall, you'll be able to find drain pipes at the foot of that wall. You won't need to consider routing the waste out. 

If the kitchen sink is under a window, you'll have a shorter run of waste pipe. Thus, it enables a good flow of wastewater and easy access. 

So what exactly happens if you want to relocate the sink? The issue you or professionals will have to deal with is laying extra piping under the floor. Consequently, if there are any blockage problems or other issues, you will need to dig up the floors to access the plumbing. 

All in all, you'll have to pay more to fix these kinds of plumbing issues. 


Odor is an aspect that most won't consider. Though, it depends on how quick you are with the dishes. If you're finding yourself leaving tons of plates, containers, and cooking utensils in the sink, it can get stinky relatively quickly. 

If the sink isn't near the window, the odor will likely spread throughout the kitchen. Under a window, the foul smell will have a place to go.

Additionally, if you're washing dishes with hot water, some steam might build up in the process. Likewise, the steam will escape through the window. That leaves you with less moisture to deal with. 

Additional Considerations

The last two aspects to consider are subjective, meaning it's all up to your personal preference.

If you prefer to wash dishes by hand, you'll be spending a fair amount of time standing over the kitchen sink. Wouldn't it be nice to at least have a nice view to look at? A window above the kitchen sink can let you look out at your yard, garden, or neighborhood while you do the dishes.

Simply put, having a window above the kitchen sink makes a dull chore a lot less boring. In this sense, one of the reasons kitchen sinks tend to be under windows is through tradition

Another reason to place a kitchen sink under a window is aesthetics. If you're planning to make the sink a focal point of the kitchen, the window above the sink will only increase the visual appeal of the space. 

Having The Kitchen Sink In Other Areas

Now, let's go over some arguments against having a kitchen sink under a window. 

Plumbing and Appliances

The essential question to ask is: where are your plumbing and appliances? This situation applies to people with an already established kitchen. 

In some cases, appliances like the dishwasher will be across the room from the sink. It's preferable to have the dishwasher and the sink close to each other. Otherwise, you'll be carrying wet dishes that leave a trail across the floor. 

Plumbing will be less of a headache if you place appliances that need access to the plumbing lines together. 

Dishwashing Frequency

While a view of the outside is pleasant, you might not spend enough time enjoying it. Consequently, it begs the question: do you really need a window above the sink? Additionally, if you don't wash dishes by hand often, a nice view from the window might not be important to you.

Storage Space

Convenience is the last aspect to consider. While cabinets above the kitchen sink could interrupt workflow, it might be more convenient to store small pots and dishes above the sink. If you don't have much space, you can also hang kitchen utensils above.

Can a Kitchen Sink Be Moved?

Planning renovations in an established kitchen could present some problems. Is it possible to move a sink from its original spot? Plumbers suggest that it's possible.

However, the difficulty of the job will depend on the current layout of your kitchen, the plumbing, and your budget. The primary concern when relocating a kitchen sink is the drain venting. 

The kitchen sink will need to meet building codes. It becomes a substantial problem the farther away you relocate the kitchen sink.

What Size Window Should Be Over a Kitchen Sink?

There is no rule on how big a window should be over a kitchen sink. Your personal preference can play a role in this area. Some suggest getting counter-height windows. And, if you want more counter space, you can have it bumped out too! Though, they'd only recommend a bump of 10-12 inches. 

It also depends on the type of windows you want installed. There are casement, picture, double-hung, sliding, and pass-through windows. The options available will depend on the amount of space you have to work with. 

Casement windows will be a strong contender. They are usually 17-73 inches tall and 14-35.5 inches wide. 

The next option to consider is double-hung windows. They are 36-72 inches tall and 24-48 inches wide.

As you can see, there's a lot to consider. The size will depend on how you plan to lay out your kitchen. What look you're going for will also influence this decision. 

How Much Does It Cost To Relocate a Kitchen Sink?

Relocating a kitchen sink will involve messing with the plumbing and maybe even purchasing a new sink. As some suggest, remodeling the kitchen is the best time to relocate the sink. This way, you can accommodate the new drain line and the faucet lines. 

You can also rearrange the kitchen cabinets to fit the new sink. Doing all of this will cost you around $440-$2,600

What Do You Do With a Window Over a Kitchen Sink?

As mentioned, what you do with the window over the kitchen sink will depend on the look you're trying to achieve. However, sometimes we don't have a specific plan in mind. So, if you need decor ideas for a kitchen window, let's go over some!

If you want to add more visual appeal, you can install decorative lighting above the windows. Sconce lighting can provide plenty of lighting for your workspace. Additionally, it could also fit the overall decor of the kitchen.

Another option could be recessed lighting. It won't stick out above your kitchen window—so, you'll have an unobstructed view of the outside. As an added benefit, you get dedicated lighting for your workspace.

Some people are big on seasonal changes. One way you can include your kitchen window is by hanging seasonal wreaths. This option requires more involvement. So, if you love decorating but don't care if your view is obstructed, wreaths could be a delightful choice!
