Under-Sink Storage Ideas for a Tidy Kitchen | Ease & Co

The cabinet beneath the kitchen sink is one of the easiest places for household clutter to collect. Pipes interrupt the space, bottles get pushed to the back, and small items disappear behind larger ones. The answer is not to fill every gap with containers. Organise around the plumbing, keep frequently used items within reach, and leave room to inspect the cabinet.

The simplest method: empty the cabinet, check for moisture, measure around pipes and shut-off valves, then create clear zones for sink supplies, spare items and bin liners. Choose an organiser only after checking its dimensions against the cabinet.

1. Start with a proper clear-out

Take everything out before buying or moving storage. An empty cabinet makes it easier to see how much usable space you have and to spot problems that clutter can hide.

• Group items by use: dishwashing products, cloths and brushes, bin liners, spare sponges and occasional-use supplies.
• Check bottles for leaks, damaged caps, residue or unclear labels. Follow the product label for safe use and disposal.
• Move items that belong elsewhere, such as medicines, food, pet food and unrelated tools.
• Wipe the cabinet with a surface-appropriate cleaner and let it dry fully before putting anything back.

While the cabinet is empty, look for damp patches, water marks, corrosion, swollen board, musty odours or active drips. Deal with leaks or damaged plumbing before installing storage. An organiser should never conceal a problem or make a valve difficult to reach.

2. Measure around the plumbing

Under-sink cabinets are rarely simple rectangles. The waste pipe, trap, water lines, shut-off valves and sometimes a disposal unit take up space. Measure the usable areas rather than relying only on the cabinet's outside width.

Record the internal width, depth and height. Then note where pipes enter, how far they project from the back wall, and the space needed to reach each shut-off valve. Measure the clear opening between the doors too: a rack may fit inside but still be awkward to slide through a narrow opening.

Make a quick sketch from above and from the front. Mark the pipework and divide the remaining space into usable sections. If a pipe sits in the middle, two narrower side zones may work better than one wide shelf. If it sits towards the back, a shallow organiser at the front may preserve access.

Check the door swing, hinges and any pull-out bin or drawer above the cabinet. Leave clearance for movement and maintenance instead of choosing the largest possible rack.

3. Give everyday items a clear home

A few practical zones are easier to maintain than a cabinet full of tiny boxes. Adapt these groups to what you actually use.

Daily sink supplies

Keep dishwashing liquid, a brush and the cloths you use most near the front or on the easiest-to-reach shelf. Let reusable tools dry in a suitable place between uses rather than closing wet sponges inside a container.

Refills and back-up items

Place unopened refills and spare cloths together in a separate basket or section. Keeping back-up stock away from daily-use items makes it easier to see what is running low.

Bin and recycling supplies

Store bin liners and spare recycling bags in a small open container. Keep them away from damp areas and avoid overfilling the space so bags do not snag on pipes or hinges.

Occasional-use items

Less-used items can go towards the back or on a higher shelf if they remain visible and reachable. Do not put heavy bottles where they can fall when you reach past them.

4. Choose an organiser that suits the cabinet

There is no single best under-sink rack for every kitchen. Choose one that fits the measured space, works around the pipework and lets you remove items without dismantling the whole cabinet.

If the cabinet has uneven clearance or you need flexibility, an adjustable multi-layer under-sink storage rack is designed with adjustable height and expandable width. Check its listed dimensions against your own measurements before ordering.

If reaching the back is the main frustration, consider a sliding under-sink drawer organiser. Its pull-out design can make stored items easier to reach, but confirm that it can move without hitting the trap, valves, cabinet frame or door hinges.

A simpler pull-out kitchen storage basket may suit a cabinet where one accessible basket is enough. Match the organiser to the shape of the space rather than buying several units because they look tidy in a product photo.

Before assembling a rack, read its instructions and check the dimensions. If the cabinet floor is uneven or the plumbing layout is unusual, a freestanding basket or removable bins may be more practical than a multi-level frame.

5. Use height without blocking access

Vertical storage can make a low cabinet more useful, but it should not crowd the plumbing. Place an organiser beside pipework only if it leaves connections and shut-off valves visible and reachable. Never force a shelf into position or rest a loaded rack against a pipe.

Use the lower level for stable items that are easy to lift out, and keep lighter cloths or spare bags on an upper tier. Test pull-out movement while the cabinet is empty, then add items gradually. Door-mounted holders can work only if they clear stored items, hinges and the full door swing; avoid permanent fixings unless they are suitable for your home.

6. Store cleaning products safely

Under-sink cabinets are low and often easy for children to open. Safety matters more than a perfectly styled arrangement. Household cleaners, detergents and other chemical products should remain in their original, clearly labelled containers, with caps closed and stored securely according to their instructions.

The Australian Competition and Consumer Commission advises keeping potentially harmful household products securely away from children and following product safety information. HealthyWA also recommends keeping chemicals in their original containers and in a secure place. Follow the guidance for your location and the specific product label, as storage requirements can vary.

If young children or pets can access the cabinet, do not rely on a basket or organiser to keep them safe. Use an appropriate child-resistant lock or move hazardous products to a high, locked cupboard out of reach. If the cabinet cannot be secured reliably, use it for safer household items and store chemicals elsewhere.

• Never transfer cleaners into drink bottles, food containers or unlabelled vessels.
• Keep products in original packaging and follow the label for storage, use and disposal.
• Do not mix cleaning products. Use one product as directed and follow its rinsing and ventilation instructions.
• Keep chemicals separate from food, pet supplies, medicines and items that touch dishes or food surfaces.
• Close products and return them to secure storage immediately after use.

For further guidance, read the ACCC guide to chemical and poison risks for children and HealthyWA's household chemical safety advice.

7. Keep the cabinet dry and easy to inspect

Because the sink and plumbing sit directly above this area, leave enough open floor space to notice moisture. A removable liner may make wiping easier if it suits the cabinet material, but it should not cover a leak or trap moisture underneath. Lift it occasionally to check the surface below.

Do not pack items tightly against the back wall. Keep connections visible, dry cloths and brushes before storing them, and take caddies out periodically to clean and dry them. If you notice a damp smell, water mark or drip, remove stored items and investigate promptly.

8. Make it work in a small or rental kitchen

In a compact kitchen, the cabinet beneath the sink may be the most convenient home for cleaning tools. Prioritise what you use most and move occasional-use stock elsewhere. One well-sized organiser and one small basket are often easier to maintain than several narrow containers.

For a rental, favour freestanding or removable storage that does not require permanent changes. Measure before buying, keep original fittings and avoid attaching hardware unless your agreement allows it. Explore the Kitchen Storage & Organisation collection and Home Storage & Organisation collection for other kitchen storage options.

9. A five-minute weekly reset

Once a week, open the doors while you are already tidying the kitchen. Return items to their zones, wipe up residue, check for moisture, remove empty containers and replace bin liners or daily supplies that have run out. Confirm that locks and pull-out organisers move freely and that valves remain accessible.

About once a month, remove baskets and clean underneath them. Check caps and labels, and remove anything damaged or no longer needed. Browse the Cleaning Essentials collection for tools that support your wider kitchen-cleaning routine.

Common mistakes to avoid

• Buying before measuring: a rack that is too wide or tall can block plumbing or doors.
• Hiding valves and connections: storage should not delay access for maintenance.
• Overfilling every shelf: leave room to lift items out and inspect the cabinet floor.
• Storing wet tools: damp cloths and sponges can leave residue and unpleasant smells.
• Treating an organiser as a safety lock: it does not replace secure storage for hazardous products.

Frequently asked questions

What should I keep under the kitchen sink?

Keep suitable sink tools, dry cloths, spare bin liners and selected household supplies. Store food, medicines and pet supplies elsewhere, and keep hazardous cleaners securely away from children and pets.

How do I organise around pipes?

Measure the clear spaces on each side of the pipework. Two narrow zones may work better than one wide shelf. Choose a rack only if it fits without touching pipes, valves or connections.

Are pull-out organisers worth it?

They can make items at the back easier to reach in deeper cabinets. They are useful only when the pull-out path is clear and the organiser fits the cabinet opening and plumbing layout.

Can I store cleaning products under the sink?

Only if the product labels permit it and the products can be stored securely. If children or pets can reach the cabinet, use an appropriate child-resistant lock or store hazardous products in a high, locked cupboard.

How often should I clean the cabinet?

Check weekly for drips, residue and misplaced items. Remove baskets and clean underneath them about once a month or whenever a spill occurs.

A cabinet that stays useful

The best under-sink setup is not the one with the most shelves. It is the one that fits around your plumbing, keeps everyday items easy to reach, allows the cabinet to stay dry and leaves hazardous products securely stored. Start with measurements, choose only the storage you need and keep a short reset routine. A few sensible zones can turn an awkward cabinet into a useful part of your kitchen without making maintenance harder.
