Should Your Kitchen Sink Be Under A Window? – Expert Advice & Tips

I find it funny how often this question comes up with clients. Should your kitchen sink be under a window? However, when I stop and think about it, this seemingly simple query is, in fact, a complex consideration that intertwines aesthetics, functionality, and tradition.

In this post, I’ll answer if your kitchen sink should go under a window, look at why it’s historically been this way as well as answer some popular questions about the topic.

Let’s get into it!

Does Your Kitchen Sink Have to Go Under a Window?

The short answer is no, your kitchen sink does not have to be positioned under a window.

While this is a popular design choice, it’s by no means a hard and fast rule. The placement of your kitchen sink should be determined by a variety of factors, including the features of your room, the layout of your kitchen, and most importantly, what works best for you and your lifestyle.

The key is to consider how you use your kitchen. Do you need a view to enjoy while washing dishes, or face into the room and your guests and family, or would you prefer to have your sink out of the way and hidden?

Although placing your sink in front of a window can make a lot of sense, it’s not your only option. Your kitchen sink could be placed in an island, against a wall without a window, or even in a corner (although I don’t really recommend that), depending on your kitchen’s configuration and your personal preferences.

Remember, the ultimate goal is to create a kitchen that is functional, comfortable, and aesthetically pleasing to you.

So, while having a kitchen sink under a window can provide a pleasant view and an abundance of natural light, it’s not the only option. It definitely pays to explore various kitchen layouts, consider your needs, and make a choice that best suits you.

Why is the Kitchen Sink Normally Under a Window?

Historically, the kitchen sink was positioned under a window for a number of reasons.

One of the most practical was the ease of plumbing installation. The sink’s location on an outside wall meant that the plumbing and drain pipes had a short and straightforward route out to the drains. This not only simplified the installation process but also made any necessary plumbing repairs or maintenance more accessible. It’s also a hangover from when we didn’t have indoor plumbing. The kitchen window would have been used to bring in and dump out water.

Another reason was the benefit of natural light. Before the advent of bright, energy-efficient indoor lighting, the window provided essential illumination for washing dishes and preparing food. This natural light source made it easier to see and ensured a cleaner, more hygienic kitchen environment. Not to mention easy access to ventilation and fresh air.

Additionally, the window offered a view (some better than others). In the days before dishwashers, washing up was a more time-consuming task. Having a window to look out of provided a pleasant distraction and made the chore of washing dishes a bit more enjoyable. Even today, in homes without dishwashers, this aspect remains relevant.

And as well as the view, placing the kitchen sink under a window creates a sense of openness. With a window in place, there are no overhead wall cabinets to encroach on your space. This open layout can make your kitchen feel larger and more inviting, enhancing the user experience by reducing the feeling of being boxed in.

So, while the placement of your kitchen sink is flexible and should ultimately suit your personal needs and kitchen layout, the tradition of positioning it under a window has endured for these practical and aesthetic reasons.

Pros of Having a Kitchen Sink Under a Window

Choosing to place your kitchen sink under a window can significantly enhance your kitchen’s aesthetics and functionality. Here are some of the key advantages of this design choice:

Natural Light: The most immediate benefit of having a kitchen sink under a window is the abundance of natural light. This can make tasks like washing dishes and food preparation easier and more enjoyable. Natural light can also help save energy during the day by reducing the need for artificial lighting, making your kitchen more eco-friendly.

Pleasant View: A window above the sink can transform mundane tasks into moments of relaxation. Whether it’s a beautiful garden, a bustling street, or your children playing in the backyard, a window can provide a pleasant distraction from the task at hand. It can turn the time you spend at the sink into an opportunity to pause and appreciate your surroundings.

Easy Access for Plumbing: Having the kitchen sink on an exterior wall, as is often the case when it’s under a window, simplifies the plumbing installation. The proximity to an outside wall allows for a more direct route for plumbing, draining, and waste pipes, making the setup more efficient and potentially reducing the cost and complexity of installation or future maintenance.

Openness and Space: With a window above the sink, there are no overhead cabinets, creating a sense of openness. This open layout can make your kitchen feel larger and less confined, enhancing the overall user experience. It can also contribute to a more modern and airy aesthetic, particularly beneficial in smaller kitchens where space is at a premium.

Options for Placing a Kitchen Sink Without a Window

Designing a kitchen without a window doesn’t mean you’re limited in terms of layout and functionality. Here are two key options for placing a kitchen sink without a window, each with its own unique benefits:

Kitchen Island

Placing your sink in a kitchen island is a popular and, under the right circumstances, highly functional choice. This central location creates a hub for cooking and cleaning, making your kitchen more social and interactive. It allows you to face your family or guests while preparing meals or cleaning up, fostering a more engaging environment.

Moreover, a sink in an island can contribute to an efficient kitchen work triangle. The work triangle, a concept in kitchen design, refers to the optimal positioning of the sink, stove, and refrigerator for maximum efficiency. With the sink in the island, you can easily move between these three points, streamlining your cooking and cleaning processes.

Just be aware that having a sink in an island can cause what I like to call a ‘mess magnetic’ for dirty dishes and may spoil the look of that beautiful island focal point. More about that in the post below: ⬇️

Against a Wall

If a kitchen island isn’t feasible in your space, placing your sink against a wall can be your only alternative. But this is by no means a ‘bad’ thing!

This setup can allow you to keep your ‘wet’ appliances (like the sink, dishwasher and maybe washing machine) close together, simplifying plumbing and creating a focused area for cleaning tasks.

To enhance accessibility and avoid a closed-in feeling, you might choose to forgo upper wall cabinets in this section. Or, consider incorporating shallow open shelves. These can provide storage for dishes and glassware while keeping the space open and airy.

Without a window, lighting becomes even more critical. Wall-mounted lights or sconces can provide targeted illumination for your sink area, ensuring you have plenty of light for washing dishes and preparing food. These lighting fixtures can also serve as a design feature, adding character and style to your kitchen.

A kitchen sink without a window offers opportunities for creative and efficient design. Whether you opt for a sink in a kitchen island or against a wall, you can create a kitchen that’s functional, attractive, and tailored to your needs.

Should A Kitchen Sink Be Placed Next To The Dishwasher?

In my personal opinion, ideally, yes!

Keeping ‘wet’ appliances like the sink and dishwasher close to each other is a smart design choice for several reasons. Firstly, in terms of plumbing, it simplifies the process. Having both the waste pipe and feed plumbing in one area can make the installation easier and potentially reduce maintenance issues down the line.

Secondly, it enhances the efficiency of your kitchen tasks. If you’re someone who prefers to rinse dishes before placing them in the dishwasher, having these two appliances side by side means you won’t be dripping water on the floor or walking across the room between each task. This can make your kitchen routines smoother and less messy.

A particularly effective setup, and a personal favourite of mine, is having the sink flanked by the dishwasher on one side and an integrated bin on the other. This layout creates a highly efficient ‘clean-up’ zone. You can scrape leftovers into the bin, rinse the dishes at the sink, and then load them straight into the dishwasher. This keeps everything contained in one area, making your clean-up process quicker and more streamlined.

So, while the placement of your sink and dishwasher will depend on your kitchen’s specific layout and your personal preferences, keeping these appliances close together can enhance your kitchen’s functionality and efficiency.

Does a Kitchen Sink Need to be Centered in a Cabinet?

In my honest opinion, yes! (If you can) 😬

When it comes to kitchen design, I think symmetry and balance play a crucial role in creating an aesthetically pleasing space.

Centring the sink within the cabinet can contribute to this sense of balance and order in your kitchen. As it’s a break in the cabinets and countertop, this can be an area that draws the eye, and any imbalance, such as a sink that’s off-centre, can be noticeable and potentially disruptive to the overall design.

However, it’s important to remember that practicality should also guide your kitchen design decisions. There may be physical limitations or practical considerations that prevent you from centring the sink in the cabinet. For instance, plumbing configurations, the position of other appliances, or the layout of your kitchen might dictate where your sink can be placed.

In such cases, it’s essential to find a balance between aesthetics and functionality. While symmetry is desirable, it shouldn’t come at the expense of a kitchen that’s practical and comfortable to use. After all, your kitchen is a working space, and its design should support your cooking and cleaning routines effectively.

Final Thoughts…

There you have it! My take on the ‘Should your kitchen sink be under a window’ debate.

While there are very strong arguments for why putting your sink under a window in the kitchen is a good idea, it’s not the only option you have. It all comes down to your particular room features, kitchen layout and personal preferences.

Just make sure to optimise that sink area ‘wet zone’ as best you can and help create a functional, practical and flowing kitchen layout!
