MASTER YOUR UNDER-SINK STORAGE

The cupboard under your kitchen or laundry sink can be one of the trickiest spaces in the home to organise.

Plumbing takes up valuable room, while pipes and awkward corners can make it difficult to see or reach what is stored at the back. For busy families, this can quickly turn into a cluttered cupboard filled with half-used cleaning products, spare cloths and items you forgot you had.

The good news? You don't need a complete cupboard makeover to create better under sink storage. With a simple declutter, a few practical storage solutions and a system that works for your household, you can turn this awkward space into an organised and easy-to-use zone.

Here’s how to get started.

1. Start by decluttering your under-sink space

Before adding any new storage, take everything out of the cupboard and sort it into a few simple groups:

  • Keep and use regularly

  • Keep but use occasionally

  • Empty or expired

  • No longer needed

Check the expiry dates on your cleaning products and dispose of anything that’s no longer suitable for use. You may also find several products that perform a similar job. Where it makes sense, choosing multi-purpose products can help reduce the number of bottles taking up valuable space.

2. Measure your under-sink cupboard

Once you've decluttered, measure the space you're working with.

Under-sink cupboards aren't always straightforward. Pipes, plumbing and cabinet doors can affect how much usable space you actually have, so measuring first will help you choose storage that fits.

Measure the:

  • Width of the cupboard

  • Depth of the available space

  • Height beneath and around the plumbing

3. Create categories that work for your family

The best under sink organisation system is one that everyone in the household can understand.

Instead of grouping products randomly, sort them according to how you use them. For example:

  • Dishwasher supplies

  • Cleaning sprays

  • Cloths and sponges

  • Laundry products

Once everything is categorised, think about what you reach for most often. Keep everyday essentials towards the front of the cupboard, while spare or less frequently used products can go towards the back.

This makes it easier to find what you need and, importantly, easier to put things away afterwards.

4. Use Modular Containers for everyday essentials

Inabox Modular Containers come in a range of sizes, including 5L, 8L, 19L and 28L, making it easy to create a combination that works for your cupboard. Use them to group everyday cleaning and household products together, rather than having individual bottles scattered across the cupboard.

For kitchen sink storage, a 5L Modular Container can be useful for grouping taller everyday items while keeping them together and easy to access. Modular Insert Trays can also be added to help organise smaller items within your containers. They're useful for keeping things such as dishwasher tablets, plugs and other small cleaning accessories contained and easy to find.

5. Make use of vertical space with Stackable Organisers

Don't let awkward plumbing stop you from making the most of your cupboard.

Stackable Organisers can help create a more flexible storage system by allowing you to build upwards where the cupboard layout allows. Inabox Stackable Organisers are available in multiple shapes and sizes, allowing you to mix and match them to suit your under sink storage needs.

They’re ideal for smaller essentials such as:

  • Sponges/Cloths

  • Scrubbing brushes

  • Cleaning accessories

  • Dishwasher supplies

Larger Stackable Organisers can also be used for bulkier items where there is enough space beneath or beside the plumbing.

The key is to work with your cupboard layout. Look at where the plumbing sits, identify the usable space and build your storage system around it.

6. Make your system easy to maintain

An organised cupboard doesn't need to stay perfect. It just needs a simple system that is easy to maintain. Once everything has a designated place, try to return products to their category after use. If one container is constantly overflowing or you find yourself moving things around to reach what you need, it's a sign that your system may need adjusting.

A quick reset every few months can also help. Check for empty or expired products, remove anything you no longer need and rearrange your storage as your family's needs change.

Turn your under-sink cupboard into a space that works

Just because your under-sink cupboard needs to work around plumbing, doesn't mean it has to be difficult to organise.

Start by decluttering, measure the space and group similar items together. Use a combination of storage containers, Modular Containers, Insert Trays and Stackable Organisers to create a system that suits your household.

The best under sink storage ideas are the ones that make everyday life easier. When cleaning supplies are easy to find and everything has a place, even a small cupboard can feel much more manageable.

And that's the real win: less rummaging, less clutter and a little more calm in your everyday routine.
