Space-Saving Storage Ideas for Small Bathrooms
A small bathroom can feel like a constant puzzle. You need a place for everything—towels, toiletries, cleaning supplies—but floor space is at a premium. The good news is that with a little creativity, you can transform a cramped bathroom into a functional and organized oasis. It’s all about looking up, using hidden spaces, and choosing smart solutions that work for you.
This guide will walk you through clever storage ideas to help you conquer clutter. We’ll explore ways to maximize your existing cabinets, take advantage of your vertical space with shelves, and finally make sense of that awkward area under the sink. Get ready to turn your small bathroom into a beautifully organized space.
Maximize Every Inch of Cabinet Space
Bathroom cabinets and medicine chests can quickly become cluttered jungles. Instead of just tossing items inside, a few simple organizers can double or even triple your usable space.

Use Dividers and Bins
Drawer dividers are not just for the kitchen. Use them to create dedicated zones for makeup, skincare, and dental care products. This stops items from rolling around and getting lost in the back. For deeper cabinets, clear acrylic bins are a game-changer. You can see everything at a glance and pull out a whole category of items at once. Stackable bins are even better, allowing you to use the full height of the cabinet shelf.
Think Vertically Inside Cabinets
Install small tension rods inside your medicine cabinet to hang items like tweezers or nail clippers from S-hooks. You can also add a small, multi-tiered shelf riser (often sold as a spice rack) to create levels within a single cabinet shelf. This prevents smaller bottles from getting hidden behind larger ones. Another great trick is to attach a magnetic strip to the inside of the cabinet door to hold bobby pins, nail files, and other small metal tools.
Take to the Walls with Shelving
When you can’t build out, build up. Your walls offer a vast amount of untapped storage potential. Wall-mounted solutions keep your counters clear and make the room feel more open.

Install Floating Shelves
Floating shelves are a stylish and modern way to add storage. They create a clean, minimalist look while providing a perfect perch for rolled towels, decorative baskets, or pretty jars filled with cotton balls and bath salts. Install two or three shelves above the toilet—an often-overlooked area—to create a functional and attractive display. Just be sure to keep them organized and visually appealing, as everything is on display.
Utilize Over-the-Door Organizers
The back of your bathroom door is prime real estate. An over-the-door organizer with pockets can hold everything from hair styling tools and brushes to cleaning supplies and extra toilet paper. Some models come with shallow wire baskets, which are perfect for holding bottles of lotion, shampoo, and conditioner. This is an ideal solution for renters, as it requires no installation.

Consider a Ladder Shelf
A leaning ladder shelf offers a stylish, non-permanent storage solution. Its tiered design provides shelves of varying depths, perfect for holding towels, baskets, and even a small plant or two. It adds a touch of spa-like elegance to the bathroom while taking up very little floor space. Look for one made from bamboo or a water-resistant material to withstand the bathroom’s humidity.
Conquer the Under-Sink Area
The cabinet under the sink is often the most challenging space to organize due to the plumbing pipes. It can easily become a dark cavern where half-empty bottles go to be forgotten. With the right tools, you can reclaim this valuable space.

Invest in a 2-Tier Organizer
A two-tier sliding organizer is specifically designed to fit around pipes. The top shelf is typically narrower, leaving room for the U-bend, while the bottom drawer pulls out completely. This allows you to easily access items stored in the back without having to get on your hands and knees. Use it to store cleaning supplies, extra soap, and taller bottles.
Use the Inside of the Doors
Don’t forget the cabinet doors. Attach small, self-adhesive caddies or hooks to the inside of the under-sink cabinet doors. These are perfect for holding sponges, cleaning cloths, or your hairdryer and straightener. A small tension rod installed across the top of the cabinet can also be used to hang spray bottles, freeing up shelf space below.

Group Items in Baskets and Trays
For a simpler approach, use baskets or trays to group similar items together. Have one basket for cleaning supplies, another for extra toilet paper, and a third for backup toiletries. When you need something, you can just pull out the relevant basket instead of digging through a mess of loose items. This system makes it easy to see what you have and know when you’re running low on essentials.
