How to Organize Under Kitchen Sink

The space under the kitchen sink is notoriously difficult to organize — awkward dimensions, pipes in the way, and a tendency to become a catch-all for cleaning products and random items. With the right approach, it can become one of the most functional storage spaces in your kitchen.

Step 1: Start with a Full Clear-Out

Remove everything. Wipe down the cabinet interior. Check for any leaks or moisture issues before putting anything back — a damp cabinet will damage products and create mold. Fix any plumbing issues first.

Step 2: Measure Before You Buy

Measure the interior dimensions carefully, including the height, width, and depth on each side of the pipes. Note where the pipes are positioned — this determines what type of organizer will fit. Don't skip this step; under-sink spaces vary significantly between kitchens.

Step 3: Install a Pull-Out Organizer

A sliding pull-out cabinet organizer is the most practical upgrade for under-sink storage. It mounts to the cabinet floor and slides out like a drawer, giving you full access to everything at the back. No more reaching in blindly or knocking things over.

Step 4: Add a Tiered Shelf

On the side of the cabinet with more clearance, add a 2-tier under sink organizer to double your vertical storage. The upper tier is perfect for smaller items like sponges, scrubbers, and gloves. The lower tier holds taller bottles and larger items.

Step 5: Use the Cabinet Door

Mount an over-door organizer on the inside of the cabinet door for spray bottles, dish gloves, or small cleaning tools. This uses space that's almost always wasted and keeps frequently used items right at hand.

Step 6: Organize by Frequency of Use

• Front: Daily items — dish soap, sponge, hand soap refill.
• Middle: Weekly items — surface sprays, scrubbing pads.
• Back: Occasional items — drain cleaner, heavy-duty products, refill bottles.

Step 7: Add a Tension Rod for Spray Bottles

Mount a tension rod horizontally across the cabinet. Hang spray bottles by their triggers over the rod, keeping them off the shelf entirely and freeing up floor space for larger items below.

Maintenance Tips

• Check for leaks every few months — moisture is the enemy of under-sink organization.
• Refill and consolidate products regularly to avoid accumulating too many half-empty bottles.
• Do a quick purge every season — discard empty or expired products immediately.

Frequently Asked Questions

How do I organize under the sink with a garbage disposal?

A garbage disposal takes up significant space. Work around it by using the remaining space on each side with narrow pull-out organizers or bins. Measure carefully before buying any organizers.

What should I store under the kitchen sink?

Cleaning supplies, dish soap, sponges, trash bags, and under-sink refills are ideal. Avoid storing food, medications, or anything that could be damaged by moisture or cleaning product fumes.

How do I keep the under-sink cabinet from getting messy again?

Use bins and organizers so everything has a designated spot. Make it a habit to return items to their spot immediately after use. Do a quick tidy every week when you clean the kitchen.

Can I add shelves under the sink?

Yes — adjustable tiered organizers work well and don't require any installation. For a more permanent solution, some people add a small tension-mounted shelf on the side of the cabinet away from the pipes.
