How to Organise Under the Kitchen Sink: A Step-by-Step Guide for Australian Homes

The fastest way to organise under your kitchen sink is to empty the whole cabinet, sort everything into categories (cleaning supplies, bags, spares, bin liners), then rebuild the space using a pull-out drawer organiser or stackable bins so every category has its own clearly labelled spot. Most Australian under-sink cabinets can go from chaos to a fully working system in under an hour, and the system holds up because each item has one home instead of a free-for-all.

Under the sink is one of the hardest spots in any home to keep tidy. It is deep, often dark, interrupted by pipes, and used for a strange mix of things: dish soap, spare sponges, bin liners, chemical sprays, and whatever doesn't have another home. Unlike a pantry shelf, you can't just see everything at a glance, so clutter builds up fast and stays hidden until the next big clean-out.

Why Under the Sink Becomes a Dumping Ground

Three things work against this space specifically. The plumbing breaks up the usable area into awkward left and right sections. The depth means anything placed at the back disappears from view (and from memory). And because it's low to the ground, it's the easiest cabinet in the kitchen to open and shove something into without thinking.

The fix isn't a single clever product. It's a repeatable system: sort once, assign a container to each category, and label it so the system survives daily use, not just the week after you clean it out.

Step 1: Empty and Sort Everything

Pull every item out onto the bench. Group things into rough categories as you go:

• Everyday cleaning (dish soap, sponges, cloths)
• Occasional cleaning (oven cleaner, specialty sprays)
• Bags and liners (bin bags, reusable bags)
• Spares and refills (dishwasher tablets, extra sponges)
• Anything that's expired, empty, or doesn't belong under the sink at all

Be honest about that last category. Under-sink cabinets are notorious for collecting things that have nothing to do with the kitchen.

Step 2: Measure Before You Buy Anything

Measure the width, depth, and height on both sides of the pipe before choosing containers. Under-sink cabinets vary a lot between Australian kitchen layouts, and a container that doesn't clear the plumbing will sit there unused instead of solving the problem. If you only measure one thing, measure the height from the cabinet floor to the underside of the sink basin, since that's usually the tightest constraint.

Step 3: Choose the Right Containers for Each Zone

Different categories need different containers. A one-size-fits-all approach is why most under-sink systems fail within a month.

A two-tier pull-out drawer organiser is one of the simplest ways to double your usable space without touching the plumbing, and it's a good starting point if you only want to fix one thing today. For a full rebuild in one go, a pre-assembled under sink storage starter pack covers most of the categories above in a single purchase, which is often more cost-effective than buying each container separately. Browse the full under sink storage collection to compare options against your own measurements.

Step 4: Label Every Container

This is the step most people skip, and it's the reason most under-sink systems collapse within a few weeks. A label means anyone in the house (not just the person who set the system up) puts things back in the right spot. Clear, durable custom home organisation labels on bins and baskets turn "somewhere under the sink" into a specific, visible instruction.

Step 5: Build in a Five-Minute Monthly Check

Set a recurring reminder, once a month, to do a five-minute check: wipe down any spills, toss anything expired, and confirm nothing has crept back into the "doesn't belong here" pile. This is the difference between a system that lasts and one that needs a full redo every six months.

Does This Work for the Bathroom Sink Too?

Yes. The same zone-and-label method applies under a bathroom vanity, just with different categories (toiletries, cleaning, spares, first aid basics). If your kitchen and bathroom use matching kitchen storage containers and the same labelling style throughout, the whole home starts to feel like one coordinated system rather than a room-by-room patchwork.

Frequently Asked Questions

What is the best way to organise under a kitchen sink?
Sort items into categories first, then assign each category its own container (a pull-out drawer organiser for awkward corners, stackable bins for bags and spares), and label every container clearly so the system stays organised after daily use, not just on clean-out day.

How do I stop bottles and sprays falling over under the sink?
Use a caddy or bin with a solid base and sides rather than storing bottles loose on the cabinet floor. Grouping bottles by height inside one container also stops tall items toppling onto smaller ones every time the door opens.

What is the best under sink organiser for a small Australian kitchen?
A slim two-tier drawer organiser is usually the best starting point for a small cabinet, since it adds a second level of storage without needing extra floor space either side of the plumbing.

How often should I clean out under the kitchen sink?
A full clean-out once or twice a year is enough if you build in a five-minute monthly check in between, since that catches spills and expired products before they turn into a bigger job.
