1- Keep The Space Fresh

Before you start organizing the space under your kitchen sink, make sure to protect your items from humidity and odors.

Since this area is prone to moisture buildup, taking the right precautions will help keep your supplies fresh and damage-free.

One simple solution is placing activated charcoal bags or an open box of baking soda inside the cabinet to absorb unwanted smells and neutralize the air.

Another great option is hanging a DampRid moisture absorber, which effectively traps excess humidity and prevents mold or mildew growth.

By setting up these precautions first, you’ll create a cleaner, fresher space—ensuring that everything you store stays in top condition.

2- Use Under Sink Waterproof Mat

Placing a waterproof mat under the kitchen sink cabinet is a simple yet effective way to protect the floor from water spills.

Leaks, spills, and moisture buildup are common in this space, and a protective liner helps prevent water damage and mold growth.

Choose a mat with raised edges to contain spills and stop water from seeping into the cabinet.

For extra durability, opt for a silicone or plastic liner that is easy to clean and resistant to moisture.

3- Under the Kitchen Sink Organizer

Now that we have the arrangements in place to protect against water damage, let’s talk about under-the-sink organizers.

One of the best solutions is a two-tiered pull-out organizer, designed specifically for this tricky space.

Its lower tier is wide, providing ample storage for larger items like cleaning supplies, while the upper tier is narrow, ensuring there’s enough room for the sink bottom and pipes.

The height is adjustable, so you can customize it to fit your specific cabinet space, making it a versatile solution for any kitchen.

This clever design maximizes vertical space and keeps everything easily accessible and neatly arranged.

4- Use Old Plastic Containers

Another simple yet effective way to organize the space under your sink is by using plastic containers and baskets.

Gather as many stackable bins or baskets as possible and arrange them neatly to create separate storage sections.

Use them to store and categorize cleaning supplies, ensuring everything has a designated spot and stays clutter-free.

These containers are also great for holding unused shopping bags, canned goods, and sealed boxes, making the most of every inch of space.

5- Mesh Storage Baskets

If you have enough space under the kitchen sink, consider using mesh storage baskets, preferably two or three tiers, to help you organize items properly.

These multi-level baskets allow you to store more without taking up extra floor space, making them perfect for maximizing storage.

The mesh design ensures proper airflow, preventing moisture buildup and keeping your supplies fresh and dry.

You can use them to separate frequently used cleaning products, dishwashing essentials, or even extra sponges and cloths.

6- Attach Hooks On The Doors

Another smart way to maximize under-the-sink storage is by using Command adhesive hooks on the inside of the cabinet door.

These hooks provide a quick and damage-free solution for hanging cleaning brushes, dishcloths, and gloves, keeping them off the cabinet floor and within easy reach.

It’s especially wise to hang dishwashing essentials under the sink, so you can grab them quickly when needed.

For added convenience, use different-sized hooks to accommodate various items, from sponges and scrubbers to spray bottles.

7- Attach An Adhesive Caddy

Another clever way to add extra storage under the sink is by using an adhesive caddy on the inside of the cabinet door.

These self-adhesive organizers are perfect for holding sponges, small cleaning supplies, plastic bags, and cleaning cloths, keeping them off the cabinet floor and neatly stored.

If you prefer a DIY solution, simply take a lightweight plastic container and attach it to the cabinet door using strong double-sided adhesive tape.

This budget-friendly hack allows you to customize the storage space and create an easy-to-reach spot for everyday essentials.

8- Dedicate A Place For Everything

To keep your under-sink space organized and clutter-free, use clear wire bins and floating shelves for storing paper towel rolls, dishcloths, cleaning supplies, brushes, and sponges.

Dedicate one basket for each type of product, so everything has a designated spot and stays easy to find.

Clear wire bins help keep items visible, preventing you from losing track of supplies or buying duplicates.

Adding floating shelves creates extra vertical storage, making the most of the available space.

9- Stackable Shelf Risers

To maximize under-the-sink storage, use stackable shelf risers to create extra layers of storage.

By adding multiple levels, you can separate and organize items efficiently, ensuring everything is easily accessible.

These risers help you store more without cluttering the space, making it easier to reach cleaning supplies, sponges, and dishcloths without digging through piles.

Opt for adjustable or expandable risers to fit your cabinet dimensions and make the most of every inch.

10- Door Mounted Trash Bin

Look at this smart and space-saving idea that is to attach small trash bins to the inside of the cabinet door, allowing them to slide out when the door is opened.

This makes throwing trash more convenient while keeping the bin hidden when not in use, maintaining a clean and clutter-free kitchen.

You can use a pull-out mechanism or hinged brackets to ensure the bin moves smoothly with the door.

This setup is perfect for quickly disposing of food scraps, used sponges, or small waste items while cooking or cleaning.

11- Use Pull-Out Bins

The under-the-sink space can be a perfect spot for trash bins and recycling bins, keeping them out of sight yet easily accessible.

A pull-out system allows the bins to slide out smoothly, making it effortless to dispose of trash or sort recyclables.

Once the bins are in place, you can utilize the remaining space to organize cleaning supplies that come in handy for kitchen cleaning or dishwashing.

12- Use Tension Rods

A brilliant way to maximize under-the-sink space is by installing tension rods inside the cabinet, right in front of the sink.

These rods create a hanging storage solution for cleaning supplies, spray bottles, and dishwashing essentials, keeping them off the cabinet floor.

Simply hook the spray bottle triggers over the rod, making them easy to grab while freeing up shelf space for other items.

You can also use S-hooks to hang scrub brushes, gloves, or microfiber cloths, ensuring everything stays organized and within reach. 

13- Attach A Paper Towel Holder

Another great idea is to attach a paper towel holder to the inside of the cabinet door under the sink.

This allows you to hang a roll of paper towels or trash bags, keeping them easily accessible and off the cabinet floor.

For trash bags, simply slide the roll onto the holder and pull out a bag as needed, making waste disposal more convenient.

14- Label The Containers

A simple yet effective way to keep your under-sink space organized is by using stackable plastic containers with labeled names.

Dedicate a box for each category—sponges, dish soap refills, trash bags, or cleaning wipes—so everything has a designated spot.

Adding labels makes it easy to identify and access items quickly, preventing clutter and misplaced supplies.

Stackable containers maximize vertical space, ensuring you can store more without making a mess.
