Over-the-Toilet Storage Shelf
If you’re short on closet space, vacuum storage bags can be a game changer. They compress bulky winter clothes, spare bedding, and seasonal items to a If I could recommend just one bathroom organizer, this would be it.
The space above the toilet is often completely unused, making it one of the biggest missed storage opportunities in a small bathroom. An over-the-toilet storage shelf instantly adds several levels of storage for towels, baskets, toiletries, and decorative accents—all without taking up extra floor space.
I especially love this option because it combines style with function. It helps the bathroom look cleaner while providing plenty of room for the items you use every day.
Perfect for: Apartment renters, small bathrooms, and anyone who needs extra storage without remodeling
Quick Picks: Best Bathroom Storage Ideas for Apartments
Looking for a quick solution? These are four of my favorite bathroom organizers for apartments.
Each one is affordable, easy to use, and makes a noticeable difference in a small bathroom.
Under Sink Organizer
Makes the most of unused cabinet space while keeping cleaning supplies and toiletries neatly organized.
Shower Caddy
Keeps shampoo, conditioner, and body wash within easy reach while reducing shower clutter.
Bathroom Storage Cart
A slim rolling cart fits perfectly beside the toilet or vanity to create extra storage in tight spaces.
Floating Shelves
Transforms empty walls into beautiful storage space while keeping countertops clear.
1. Under Sink Organizer
The cabinet under the sink is one of the hardest places to keep organized. Without shelves, products quickly become stacked on top of each other, making it difficult to find what you need.
A two-tier under sink organizer instantly creates more usable space by separating your everyday essentials from cleaning supplies and backup products.
Why it works
- Doubles the usable space inside the cabinet
- Keeps everyday items easy to access
- Makes cleaning supplies easier to organize
Best Amazon Pick
✔ Expandable two-tier under sink organizer with sliding drawers.
2. Shower Caddy
Shower bottles can easily take over a small bathroom. Instead of balancing shampoo and soap around the edges of the tub, a shower caddy keeps everything neatly organized in one place.
I recommend choosing a rust-resistant model with multiple shelves so there’s room for everyone’s essentials.
Why it works
- Keeps shower products organized
- Frees up floor and tub space
- Helps the shower look cleaner every day
Best Amazon Pick
✔ Adjustable shelf dividers
3. Bathroom Storage Cart
f you have a narrow gap beside your vanity, toilet, or washing machine, don’t let that valuable space go to waste.
A slim rolling storage cart is one of the easiest ways to add extra storage without making the room feel crowded. Since it rolls, you can easily move it whenever you need to clean or reach something behind it.
Why it works
- Fits into narrow spaces
- Provides additional storage without remodeling
- Easy to move and clean around
Best Amazon Pick
✔ Three-tier slim rolling bathroom storage cart.
4. Floating Shelves
When floor space is limited, it’s time to look up. Floating shelves make excellent use of empty wall space while adding style and personality to your bathroom.
I like using them above the toilet or beside the vanity with woven baskets, rolled towels, and a small plant for a clean Pinterest-inspired look.
Why it works
- Maximizes vertical storage
- Keeps countertops clutter-free
- Adds decorative storage at the same time
Best Amazon Pick
✔ Modern floating wall shelf set with hidden brackets.
5. Drawer Organizers
Drawer Organizers
Bathroom drawers often become a catch-all for makeup, skincare, hair accessories, and toiletries. Without dividers, they quickly become messy and frustrating to use.
Simple drawer organizers create dedicated spaces for each item, making your daily routine faster and helping you keep everything neat.
Why it works
- Separates different categories of products
- Makes small items easier to find
- Keeps drawers tidy with minimal effort
Best Amazon Pick
✔ Expandable bamboo drawer organizer set.
6. Over-the-Toilet Storage Shelf
One of the easiest ways to create more storage is to use the empty wall space above the toilet. This area is often overlooked, but it can hold everything from towels to toiletries without making the bathroom feel crowded.
I love this solution because it adds several shelves without taking up any additional floor space. It’s a simple upgrade that makes even the smallest apartment bathroom feel more functional.
Why it works
- Takes advantage of unused vertical space
- Provides room for towels, baskets, and toiletries
- Makes the bathroom feel more organized
Best Amazon Pick
✔ Freestanding over-the-toilet storage shelf with three shelves.
7. Storage Baskets
Storage baskets are one of my favorite ways to make a bathroom look instantly cleaner. Instead of seeing lots of small bottles and everyday items, you can group similar products together in attractive baskets.
Choose woven baskets for a warm Scandinavian look or clear bins if you prefer to see everything at a glance.
Why it works
- Hides everyday clutter
- Keeps similar items together
- Adds texture and style to open shelves
Best Amazon Pick
✔ Woven storage basket set with built-in handles.
8. Adhesive Bathroom Hooks
If you’re renting an apartment, adhesive hooks are one of the best storage upgrades you can make. They install in minutes and don’t require drilling into the walls.
Use them for towels, robes, loofahs, hair towels, or even small hanging baskets to free up valuable cabinet space.
Why it works
- No tools or drilling required
- Great for towels and everyday essentials
- Removes cleanly in most apartments
Best Amazon Pick
✔ Heavy-duty waterproof adhesive wall hooks.
9. Towel Ladder
A towel ladder is both practical and decorative. Instead of bulky towel bars, it gives you multiple places to hang towels while creating a cozy spa-inspired atmosphere.
I especially like using natural wood ladders because they fit perfectly with a bright Scandinavian bathroom.
Why it works
- Stores several towels at once
- Doesn’t require wall installation
- Adds warmth and visual interest
Best Amazon Pick
✔ Leaning wooden towel ladder.
10. Wall Cabinets
When you need extra storage but don’t want to sacrifice floor space, a wall cabinet is a fantastic solution. It keeps everyday essentials hidden behind closed doors, making the bathroom feel less cluttered.
Many modern cabinets also include adjustable shelves, allowing you to customize the storage to fit everything from skincare products to cleaning supplies.
Why it works
- Adds hidden storage above eye level
- Keeps countertops clear
- Makes the bathroom look cleaner and more spacious
Best Amazon Pick
✔ Wall-mounted bathroom cabinet with adjustable shelves.
11. Corner Shelves
Bathroom corners often go unused, even though they offer valuable storage space. Adding a few corner shelves is an easy way to keep everyday essentials within reach while making the room feel more organized.
Whether you install them inside the shower or in an empty corner near the vanity, corner shelves help maximize every inch without overwhelming a small bathroom.
Why it works
- Makes use of overlooked corner space
- Adds storage without taking up floor space
- Perfect for toiletries, candles, or small plants
Best Amazon Pick
✔ Modern corner wall shelf set.
12. Medicine Cabinet Organizer
Even a medicine cabinet can become cluttered if everything is piled together. Small organizer bins make it much easier to separate skincare, medications, dental products, and everyday essentials.
I recommend using clear containers so you can quickly see what you have without digging through crowded shelves.
Why it works
- Keeps small items neatly separated
- Makes daily essentials easier to find
- Helps maximize cabinet space
Best Amazon Pick
✔ Clear medicine cabinet organizer bin set.
13. Toilet Paper Storage
Extra toilet paper rolls don’t have to sit on the floor or get crammed into an already full cabinet. A dedicated toilet paper holder keeps spare rolls organized while making them easy to grab when needed.
Many modern designs also double as decorative accents, helping your bathroom look polished and thoughtfully organized.
Why it works
- Keeps spare rolls within easy reach
- Reduces cabinet clutter
- Adds a clean, organized look
Best Amazon Pick
✔ Freestanding toilet paper storage holder.
14. Stackable Storage Bins
Stackable bins are one of the most versatile storage solutions for any bathroom. They work well inside cabinets, on shelves, or even under the sink.
Because they stack vertically, they help you make better use of limited storage space while keeping similar items grouped together.
Why it works
- Maximizes vertical storage
- Keeps products organized by category
- Easy to rearrange as your storage needs change
Best Amazon Pick
✔ Clear stackable storage bin set.
15. Lazy Susan Bathroom Organizer
A Lazy Susan isn’t just for the kitchen. It’s one of my favorite ways to organize skincare, makeup, perfumes, and hair products inside cabinets or on countertops.
Instead of reaching behind other bottles, you simply spin the organizer until you find exactly what you need.
Why it works
- Makes products easy to access
- Prevents cluttered cabinets
- Great for skincare and beauty routines
Best Amazon Pick
✔ Rotating clear Lazy Susan organizer.
