Positioning your kitchen sink under a window is great for natural light, with cleaning and drying racks away from dining tables, and reduced plumbing costs. Installing a sink on a kitchen island is also possible, making it more sociable and an efficient part of a kitchen layout with a modern, open-plan feel.

There isn’t a single correct way to install a sink in your new kitchen, but you should consider how you use the space and whether your priorities are entertaining, aesthetics, or optimising the countertop capacity for cooking.

Sink placements are, in fact, one of the most important decisions when designing a new kitchen, because they influence how tidy the space appears, and we’ve put together some of the specific advantages and trade-offs you’ll need to consider.

Placing a Kitchen Sink on an Island vs Under a Window: Key Takeaways

  • Sinks installed under kitchen windows ensure that dirty dishes, soaking pans and drying racks aren’t a prominent feature, with plenty of natural light to make washing up quick and easy.
  • Placing a sink on an island in an open-plan kitchen ensures you’re never facing away from guests or family members, making it a more sociable way to incorporate practical sinks into your kitchen.
  • Both options can work well, and much will depend on the practicalities, your existing kitchen layout, and the sink placements you feel comfortable with.

What Is the Benefit of Fitting a Sink on My Kitchen Island?

If you’re designing or already have an open-plan kitchen with an island, installing the sink here centralises the washing areas, whether you’re fitting one main sink or a prep sink in the same space where you chop and prepare food.

Keen chefs often prefer island-based sinks because they can wash veggies, fill pots, or clean up without turning their backs on the room.

Some of the advantages include:

  • Creating a highly efficient kitchen work triangle, with equal distances between the oven, fridge and sink
  • Being able to chat and engage with other people while cooking and cleaning

However, a drawback is that installing a kitchen sink in the centre of the room often makes plumbing more expensive, and it’s hard to disguise clutter and dirty dishes, since they remain on full display.

Why Should I Install My Kitchen Sink Under the Window?

Having your sink under the window is a classic design choice, and the biggest advantage is the natural light, where you’re not facing a wall or having to turn on the lights during the day to check your dishes are properly cleaned.

You might wish to have the sink underneath the window if:

  • You already have the plumbing in this place and want a quick, budget-friendly kitchen upgrade
  • Your window overlooks the garden or another relaxing, scenic view you can enjoy while managing everyday kitchen chores
  • You’d prefer to keep the mess away from your island or kitchen table

The main downside is that you’ll need to turn away from any guests or family members while washing up, which can create a disconnect from the rest of the kitchen.

Quick Comparison: Kitchen Sinks on Islands vs Under Windows

 

Island Sinks Sinks Under Windows
Plumbing costs More costly, as most kitchens don’t have plumbing already fitted in the middle of the room Budget-conscious, with plumbing usually already available to fit a new kitchen sink
Natural light Limited – many homeowners fit spotlights or other lighting sources over kitchen islands Good, with plenty of ambient light to help make washing up easier
Design aesthetic Potential to look cluttered if dirty dishes and washing-up liquid are left on display Cleaner and less obvious appearance where dishes are away from seating areas
Sociability High – the person doing the dishes can still face family members and guests Low – washing up means the person faces away from the room
Efficiency Works very well in open plan kitchen layouts with reduced distance between the sink and fridge Depends on the layout of the kitchen, but very common in traditional kitchens
Entertaining space It can be tricky to have seating around an island with a sink due to splashes Keeps islands and dining tables clear of clutter

 

What Should I Consider When Deciding Where to Install a Kitchen Sink?

It’s worth thinking about the size of the kitchen, your budget, and whether you need to incorporate other appliances, especially a dishwasher, which might influence the relevance of some of the pros and cons we’ve explored.

In addition, our bespoke kitchen designers will ask you to discuss:

  • The space around your kitchen island and the size of the island itself, because installing a sink may reduce the usable workspace if the island isn’t large enough.
  • Dishwasher placements, as it’s common to fit the dishwasher next to a sink, but for an island sink, this can lead to water dripping as you load and unload the machine.

One of the Smile Kitchens consultants comments that, ‘Choosing the right sink, and installing it in the best location can have a surprisingly significant impact on how your kitchen functions. That’s why we suggest looking at whether you want a sociable layout with a central island sink, or a visually cleaner, lower maintenance space.’

Frequently Asked Questions

Which Is Better – an Island Sink or a Kitchen Sink Under the Window?

The best solutions will depend on your preferences, but if you love entertaining and have the capacity for a sink installed on a kitchen island, this could be a good call, with a modern layout where the kitchen space is interactive.

However, if you’re concerned about having clutter and mess in the centre of your kitchen, you may prefer a sink underneath the kitchen window, even if you have a kitchen island or plan to install one.

That means the island can remain a space for entertaining or hosting, without dishes or water splashes.

Can I Include Both an Island Sink and a Sink Beneath a Window in My Kitchen Design?

Of course! If you have a larger kitchen and want a conveniently placed prep sink on the island, with a larger sink underneath the window for washing up, this can be incorporated into your bespoke design.
