What size Kmart bins fit under a standard kitchen sink?

Most standard under-sink cabinets are about 60 cm wide and 60 cm deep, with a height of 40 cm. Kmart's medium rectangular baskets (around 30x20x15 cm) fit well. Measure your own cabinet, accounting for pipes, before buying.

How do I store cleaning supplies under the sink safely?

Keep heavy bottles in a sturdy plastic tub on the floor. Store smaller items like dishwasher tablets in lidded containers to keep them dry. Never store food or medicine under the sink due to moisture and chemical risks.

Can I use Kmart bins on the cabinet door?

Yes, Kmart sells over-door hooks and mesh pockets that attach to the inside of the door. Use them for lightweight items like spray bottles or brushes, but avoid overloading so the door closes properly.

How often should I reorganise the under-sink area?

Do a quick monthly check for leaks and spills. A full reorganise is only needed when you notice items not returning to their bins or when your storage needs change, such as switching cleaning products.

Kmart Under-Sink Storage: A Glossary of Decluttering Ideas

Why the Under-Sink Area Gets Messy

The under-sink cabinet is one of the most awkward spaces in a kitchen. Pipes, a garbage disposal, or a water filter take up the back, leaving oddly shaped gaps that standard storage boxes do not fit. Because the space is deep and dark, items get pushed to the back and forgotten, leading to clutter and duplicate purchases.

Kmart's range of bins and organisers is designed with these constraints in mind. Instead of buying one large container, the key is to use several smaller, stackable bins that can wrap around the plumbing. This glossary-style guide defines the core ideas you need to turn that dark corner into a functional storage zone.

Before you shop, measure the cabinet floor and the height from the floor to the sink base. This tells you which Kmart bins will fit and how many layers you can stack. Most under-sink cabinets are about 60 cm deep and 40 cm high, but always check your own dimensions.

Measure width, depth, and height of the cabinet interior.
Note the position of pipes and any fixed fixtures.
Decide what categories of items you need to store (cleaning supplies, sponges, bin liners).

Kmart Bin Types for Under-Sink Use

Kmart sells several bin styles that suit under-sink storage. The medium rectangular storage basket is a workhorse: it fits most standard cabinets, has open sides for visibility, and can be pulled out like a drawer. The small mesh bin is good for sponges and scrubbers, while the large plastic tub handles heavy bottles of cleaner.

Another useful option is the stackable storage container with a lid. These are ideal for keeping smaller items like dishwasher tablets or spare sponges dry and dust-free. For the area directly under the sink where pipes are, a shallow tray or caddy can sit on top of the plumbing without interfering.

When choosing, think about what you will store. Heavy liquids need sturdy plastic; lightweight items like bin liners can go in fabric bins. Kmart's range is affordable, so you can mix several types without overspending.

Bin Type	Best For	Kmart Example
Medium rectangular basket	Multi-purpose, easy pull-out	Storage Basket with Handles
Small mesh bin	Sponges, scrubbers, small tools	Mesh Storage Bin
Large plastic tub	Heavy cleaner bottles	Plastic Storage Tote
Stackable container with lid	Dishwasher tablets, small refills	Stackable Storage Container
Shallow tray or caddy	Under-pipe area, narrow gaps	Bathroom Caddy Tray

Sorting and Decluttering Before You Buy

The first step in any under-sink declutter is to empty everything out. Group items into categories: cleaning sprays, cloths and sponges, bin bags, and rarely used tools. Check expiry dates on cleaners and toss anything that is old or half-empty. This is also a good time to move any food storage items elsewhere, as the under-sink area can get warm and damp.

Once you have your piles, decide what truly needs to live under the sink. Everyday items like dish soap and sponges should be within easy reach, while occasional items like oven cleaner or spare brushes can go higher up or in a less accessible spot. Anything you use less than once a month probably belongs in a pantry or garage.

Kmart bins work best when each bin has a single purpose. Label them with a label maker or masking tape to keep the system honest. A simple rule: if a bin is overflowing, you either need a bigger bin or fewer items.

Empty the cabinet completely and wipe down the interior.
Sort items into keep, toss, and relocate piles.
Assign each keep-item category to a specific Kmart bin.
Label bins to maintain the system.

Layout Strategies Around Pipes

The pipes are the main obstacle. A common strategy is to place a shallow tray or caddy directly under the P-trap to catch drips and hold small items like pipe cleaners. On either side of the pipes, place medium baskets that slide out easily. This creates two usable zones instead of one unusable void.

For deep cabinets, consider using a pull-out shelf or a tiered riser. Kmart's stackable bins can be arranged in columns beside the pipes, leaving the front clear for the items you grab most. If you have a double sink, the plumbing often runs down the middle, so you can dedicate each side to a different category.

Another trick is to use the cabinet door for storage. Kmart sells over-door hooks and small mesh pockets that can hold spray bottles or brushes, freeing up floor space. Just make sure the door still closes fully and the weight is not too heavy.

Maintaining Your Under-Sink System

A decluttered under-sink area stays tidy only if the system is easy to maintain. Choose bins that you can pull out and wipe down quickly. Avoid overfilling; leave a little empty space in each bin so items can be replaced without jamming. Once a month, do a quick check for leaks or spills and clear out anything that has accumulated.

If you find the system drifting back to chaos, review your categories. Maybe you need a smaller bin for sponges or a larger one for cleaning sprays. Kmart's range is inexpensive, so adjusting is not a big investment. The goal is a space that works for your habits, not a perfect Pinterest photo.

Remember that under-sink cabinets can experience moisture from pipes. Place a waterproof liner or a shallow tray at the bottom to protect the cabinet floor. If you ever see mould or persistent dampness, address the leak first and consider moving moisture-sensitive items elsewhere.
