The Under-the-Sink Cabinet Before

With two daughters plus myself sharing space, beauty products, toiletries, and hair tools tend to accumulate quickly. When I went into my oldest daughter’s bathroom one day, the under-sink cabinet was a jumble. We had been tossing items in without thought and wasting vertical space. That’s when I decided an organization plan was needed.

With a few targeted storage pieces and a little planning, the space can be transformed to be more usable and visually appealing. I also kept frequently used items on the counter so morning routines are quicker and less hectic.

Why Organize Under Your Bathroom Sink?

Maximizing Space

The area under the sink is often underused. Organizing this space lets you store essentials efficiently and clear clutter from other bathroom areas. When the under-sink space was organized, our drawers suddenly had more room too. Maximizing vertical storage ensures items are easy to reach, saving time in daily routines.

Reducing Clutter

Clutter makes a bathroom feel cramped and chaotic. Decluttering under the sink creates calm and order, so you spend less time searching for products. We discarded half-empty or expired items, which immediately reduced the mess.

Keeping Things Clean

An organized under-sink area is easier to clean and helps keep products dry and dust-free. Good storage prevents items from getting stuck in the dark back of a cabinet where they can degrade or collect mildew.

Before You Start: Assess Your Needs

Take Inventory

Start by removing everything from under the sink and grouping items by type or size. This helps you see exactly what you own, what you use, and what can be discarded or relocated. For example, tall bottles might need open-top storage rather than shallow drawers.

Measure Your Space

Measure the height, width, and depth of the cabinet, and note obstacles like pipes. Accurate measurements will guide you to storage solutions that fit without wasted space.

Choosing the Right Storage Solutions

After assessing the mess, I selected storage that prioritized vertical space and visibility. The results were immediate and dramatic—everything became accessible and easy to maintain.

Stackable Bins and Drawers

Stackable bins and drawers make the most of vertical space. Clear acrylic drawers are especially useful because you can see contents at a glance and slide them out for easy access. Use them to separate lotions, body sprays, and frequently used toiletries.

Over-the-Door Organizers

Over-the-door organizers hung inside cabinet doors are great for storing hair tools and other frequently used items. They free up shelf space and keep tools accessible without cluttering counters.

Sliding Trays and Shelves

Sliding trays or pull-out shelves create extra layers of storage inside a cabinet. They’re ideal for items used often because you can slide the tray out and reach products without digging through stacks.

Creative DIY Storage Ideas

Repurposed Jars and Containers

Glass jars and small containers are an affordable, attractive option for cotton balls, swabs, hair ties, and other small items. Labeling jars keeps everything orderly and gives the cabinet a cohesive look.

Tension Rods

Tension rods mounted inside the cabinet can hold spray bottles, brushes, or cloths. They’re a renter-friendly way to use vertical space without permanent installation.

Countertop Bathroom Storage

Along with under-sink organization, keep daily essentials on the counter for convenience. A compact rotating organizer or a few attractive trays can keep the counter tidy while keeping frequently used items at hand.

A rotating organizer helps keep daily cosmetics and skincare within reach. It speeds up morning and evening routines because everything you need is easy to grab and return.

Hair Tools Organizer

An on-counter organizer for hair tools keeps blow dryers and straighteners accessible and allows hot tools to cool safely in metal cups or holders. If you use tools daily, this can save time and reduce clutter.

Maintaining Your Organized Space

Regularly Declutter

Set a routine—every three to six months—to go through items, discard expired products, and donate what you no longer use. Regular maintenance prevents clutter from returning.

Label Everything

Label bins, drawers, and jars to make it easy for everyone in the household to return items to their correct spots. Labels provide a visual cue that supports consistent organization.
