How to Organize Cleaning Supplies Under the Kitchen Sink

Learning how to organize cleaning supplies under the kitchen sink can turn a crowded cabinet into a useful storage space. The challenge is fitting bottles, bins, and cleaning tools around pipes without blocking access. With the right layout, you can keep everyday supplies easy to reach while protecting the cabinet from spills and moisture.

Quick Answer

To organize cleaning supplies under the kitchen sink, empty and clean the cabinet first. Sort products by purpose, remove unnecessary items, and measure around the plumbing. Use clear bins, a cleaning caddy, or adjustable pull-out shelves. Keep daily essentials at the front, protect the cabinet floor, and secure hazardous cleaners from children and pets.

Empty the Under-Sink Cabinet First

Clearing and organizing cleaning supplies under the kitchen sink

Start by removing everything from beneath the sink. An empty cabinet lets you see how much space you actually have and reveals problems hidden behind bottles.

Follow these steps before adding any organizers:

Remove every item. Place cleaners, sponges, brushes, and trash bags on a protected surface where children and pets cannot reach them.
Check each product. Look for empty bottles, damaged packaging, expired products, and duplicates you no longer need.
Inspect the plumbing. Check the drainpipe, supply lines, and cabinet floor for moisture, staining, or signs of leaks.
Clean the cabinet. Wipe away dust and spills using an appropriate cleaner, then dry the surfaces completely.
Decide what stays. Set aside everyday supplies and move bulky backups or unsuitable items to safer storage.

Do not pour unwanted chemicals down the drain simply to empty their containers. The EPA’s household hazardous waste guidance explains why some cleaners need special disposal.

If you find water damage, deal with the cause before putting anything back. The EPA recommends fixing plumbing leaks promptly and drying affected materials completely.

Once the cabinet is clean and dry, you can plan storage around its actual dimensions.

Sort Cleaning Supplies by Category

Grouping cleaning supplies by purpose makes them easier to find and return after use. Create separate areas for dishwashing products, surface cleaners, cleaning tools, and waste supplies.

You do not need a separate organizer for every bottle. A few practical categories will usually keep the cabinet manageable.

Group Like Items

Start by placing similar products together. This lets you see which supplies you use regularly and which ones take up unnecessary space.

Dishwashing supplies: Dish soap, dishwasher detergent, and related accessories.
Surface cleaners: Everyday multi-surface sprays and specialty cleaning products.
Cleaning tools: Brushes, gloves, and clean, dry cloths or sponges.
Waste supplies: Trash bags, recycling bags, and spare bin liners.
Backup supplies: Extra bottles and refills that are suitable for storage in the cabinet.

Keep cleaning tools separate from chemical spills and leaks. Never combine different cleaning products or transfer hazardous cleaners into unmarked containers.

Place products you rarely use in another suitable storage area if they crowd out daily essentials.

Assign Clear Bins

Clear bins help you identify supplies without searching through the entire cabinet. Choose containers that fit the available floor space and can be removed for cleaning.

Rectangular bins are useful because they can sit side by side. Handled bins are easier to lift out, especially when the cabinet is deep.

Use labels such as “Dishwashing,” “Surface Cleaning,” and “Trash Bags.” Label the organizers rather than replacing the original product labels.

Store bottles upright with their caps closed. A washable, moisture-resistant bin can contain minor drips, but it should never hide an active plumbing leak.

Avoid stacking bins so high that you must move several containers to reach something underneath.

Place Daily Essentials Front

Keep frequently used cleaning supplies near the cabinet opening. Dish soap, your regular surface cleaner, and a small brush should be easy to take out and return.

Put less-used supplies toward the back only when you can still reach them safely. A handled bin can work like a simple pull-out drawer.

For a practical layout, place dishwashing supplies on one side and general cleaning supplies on the other. Trash bags can occupy a narrow bin or another convenient space.

Store clean sponges and cloths only after they have dried. Damp materials should not sit inside tightly closed containers.

Organize Cleaning Supplies Under the Kitchen Sink Safely

Safe storage matters as much as neat storage. An under-sink cabinet is low to the floor, making cleaning chemicals easier for young children and pets to reach.

If children or pets can access the cabinet, use a secure lock or move hazardous products to a locked, inaccessible location. Poison Control advises using child-resistant cabinet latches and warns against keeping cleaners in unlocked low cabinets.

Follow these storage precautions:

Keep cleaning products in their original, clearly labeled containers.
Close bottle caps and spray nozzles after each use.
Read labels for temperature, ventilation, and storage restrictions.
Keep incompatible cleaning chemicals separate according to their labels.
Store food, medicines, and pet food away from cleaning chemicals.
Keep hazardous products out of sight and reach of children and pets.

Warning: Never mix bleach with ammonia, vinegar, or other cleaning products. Dangerous gases can form. Follow the CDC’s bleach safety instructions, and keep chemicals sealed and separated.

Dishwasher pods need extra care because their contents can cause serious injuries if swallowed or exposed to the eyes. Poison Control recommends keeping dishwasher detergent in its original packaging, out of children’s sight and reach.

Never leave hazardous cleaners accessible simply because their containers are neatly arranged.

Choose Under-Sink Organizers That Fit Around Pipes

The best under-sink organizer is one that fits your cabinet without pressing against pipes or blocking plumbing access. Measure the usable space before buying shelves, drawers, or storage bins.

Use a tape measure to check:

Width: Measure the clear space between the cabinet walls, accounting for hinges and plumbing.
Depth: Check the distance from the cabinet opening to the back, including any protruding pipes.
Height: Measure from the cabinet floor to the underside of the sink and other fixtures.
Clearance: Make sure the organizer can open fully without hitting pipes, hoses, or cabinet doors.
Access: Leave the water shutoff valves and service connections reachable.

Standard kitchen base cabinets vary in size. According to Lowe’s kitchen cabinet sizing guide, base-cabinet widths can range from 12 to 48 inches. The actual usable space under a sink depends on its plumbing and cabinet design.

Different organizers serve different needs:

Two-tier organizers: Use cabinet height to hold smaller supplies above larger bottles.
Pull-out drawers: Bring items at the back forward without deep reaching.
Adjustable shelves: Fit around awkward plumbing and accommodate different bottle heights.
Cleaning caddies: Keep frequently used supplies together in a portable container.
Turntables: Make bottles easier to reach where there is enough room to rotate them.

The IKEA under-sink storage guide also recommends modular bins, pull-out trays, and protective mats for awkward cabinet spaces.

Check each organizer’s load rating before placing heavy cleaning bottles on it. For example, one two-tier sliding organizer is rated for 50 lbs per unit. That rating does not apply to every organizer.

Choose a stable organizer that supports your supplies without blocking the sink’s plumbing.

Keep Daily Cleaning Items Within Reach

Daily cleaning should not require emptying the cabinet to find one product. Position essential supplies where they are visible and easy to lift out.

A simple under-sink layout can include:

Front left: Dish soap and regular dishwashing tools.
Front right: Everyday surface cleaner in a secure, removable bin.
Side area: Trash bags and recycling supplies.
Back area: Less-used products that remain accessible and suitable for storage.
Cabinet door: Lightweight hooks for dry gloves or small brushes, where clearance allows.

If you clean several rooms, a handled caddy can hold the products you regularly carry around the house. Return it to a secure storage location after use.

For deep cabinets, a pull-out drawer offers better access than pushing loose bottles against the back wall.

Check the door clearance before attaching any hooks or baskets. Door-mounted storage should not collide with interior bins or prevent the cabinet from closing securely.

Use Vertical Space to Store More

Vertical storage makes better use of the height beneath your sink. Stackable bins, tiered shelves, and dividers can help you store supplies without filling the cabinet floor.

However, the plumbing and sink basin limit where extra levels can fit. Choose storage that remains stable and easy to access.

Stackable Bins

Stackable bins are useful for small items such as spare sponges, cloths, and trash bags. They let you organize supplies upward instead of spreading everything across the cabinet floor.

For the best results:

Use sturdy bins designed for stacking.
Keep heavier supplies on the bottom level.
Place light, less-used items above.
Choose clear containers so you can identify their contents.
Leave enough space to remove each bin without disturbing the plumbing.

Avoid placing heavy liquid bottles on weak lids or unstable stacks. If you cannot reach the lower bin without dismantling the stack, a pull-out system may be easier to use.

Tiered Storage

Tiered storage creates separate levels for large and small cleaning supplies. A two-tier organizer can hold taller bottles below and shorter items above, provided both levels have enough clearance.

For example, the lower level can hold upright cleaning bottles while the upper level stores small brushes, dry cloths, or lightweight accessories.

Sliding shelves are especially useful in deep cabinets because you can pull supplies toward you instead of reaching behind the drainpipe.

Before installing a tiered unit, check its total weight capacity, mounting requirements, and clearance around the plumbing.

Never force an organizer into a space where it touches water lines or prevents access to shutoff valves.

Vertical Dividers

Vertical dividers create separate sections for flat or narrow supplies. They are useful for organizing cleaning cloths, trash bag rolls, and lightweight tools.

You can also use adjustable organizers or tension rods where the cabinet layout permits.

Try these arrangements:

Use dividers to separate trash bags, small brushes, and cleaning accessories.
Add narrow bins beside the plumbing to use otherwise awkward gaps.
Hang lightweight cleaning tools on suitable hooks or a secure tension rod.
Keep tall spray bottles upright in a stable container.

A tension rod may hold lightweight cloths or spray bottles if its rating and placement allow. Do not overload it or let hanging products interfere with pipes.

Pro Tip: Before filling a new organizer, slide it in and out while opening and closing the cabinet doors. If your faucet has a pull-down hose, check its movement too. This helps identify hidden clearance problems before the shelves are loaded.

The goal is to use vertical space without making cleaning supplies harder to reach or inspect.

Maintain a Clutter-Free Under-Sink Cabinet

A well-organized cabinet stays useful only when its layout is easy to maintain. Regular checks prevent empty bottles, unnecessary backups, and damaged supplies from building up again.

Use this simple maintenance routine:

After cleaning: Return products to their assigned bins and close the cabinet securely.
When supplies run low: Check what you already own before buying replacements.
Every few months: Remove everything needed to inspect the cabinet floor and plumbing.
During inspections: Check containers for leaks, damage, and expiration information.
When your needs change: Adjust the storage layout instead of adding more clutter.

Use a removable, moisture-resistant mat to make routine cleaning easier. Check beneath it so trapped water does not go unnoticed.

Keep only supplies that fit comfortably without hiding the plumbing or blocking cabinet access.

A useful way to test your layout is to retrieve each everyday item and return it to its place. If you have to shift several bottles to reach one product, simplify that section.

With consistent maintenance, your under-sink cabinet can remain tidy without a complicated organizing system.
