A small bathroom can be surprisingly difficult to keep organised. Between toiletries, towels, cleaning supplies, skincare and everyday essentials, it’s easy for counters and cupboards to become cluttered.
The good news is that you don’t necessarily need a bigger bathroom—you just need to make better use of the space you already have.
From clever under-sink storage to wall-mounted shelves and over-the-door organisers, there are plenty of affordable ways to create extra storage without making your bathroom feel cramped.
Here are 15 bathroom storage ideas for small spaces that can help you create a tidier, more organised bathroom.
1. Under-Sink Storage Organisers
The cupboard underneath your bathroom sink is often one of the most underused spaces in the room.
A two-tier organiser or pull-out storage system can help you make use of the vertical space while keeping toiletries and cleaning products easy to reach.
Look for adjustable options if your sink has awkward plumbing underneath.
Why it’s worth considering:
- Makes use of otherwise wasted space
- Keeps cleaning products together
- Creates separate storage levels
- Helps keep the bathroom counter clear

2. Over-the-Toilet Storage
The wall above the toilet is valuable storage space, particularly in a small bathroom.
A slim shelving unit can provide somewhere to keep spare toilet rolls, towels, toiletries and decorative items without taking up floor space.
If you prefer a less bulky look, consider a couple of floating shelves instead.
Why it’s worth considering:
- Uses vertical space
- Doesn’t take up much floor area
- Ideal for towels and toilet rolls
- Can also add a decorative touch

3. Wall-Mounted Bathroom Shelves
If you’re short on cupboard space, look upwards.
Wall-mounted shelves can turn an empty wall into useful storage for skincare, folded towels, toiletries or small baskets.
For a rental property, removable or adhesive shelves may be worth considering where suitable.
Why it’s worth considering:
- Frees up counter space
- Makes use of empty walls
- Keeps everyday products accessible
- Available in many styles

4. Shower Caddy
Shower products can quickly take over the bath or shower area. A shower caddy gives shampoo, conditioner, shower gel and other essentials a dedicated home.
Choose a design that suits your shower setup and check the dimensions before buying.
Why it’s worth considering:
- Keeps shower products together
- Reduces clutter around the bath
- Makes products easy to reach
- Great for smaller showers

5. Bathroom Drawer Organisers
If you have a bathroom vanity with drawers, small compartment organisers can make a huge difference.
Use them to separate makeup, skincare, hair accessories, toothbrushes, razors and other small items.
Instead of digging through one messy drawer, you’ll be able to see exactly where everything is.
Why it’s worth considering:
- Keeps small items separated
- Makes everyday routines easier
- Prevents drawers becoming cluttered
- Easy to remove and clean

6. Over-the-Door Organiser
The back of your bathroom door is an often-forgotten storage opportunity.
An over-the-door organiser can provide multiple pockets for toiletries, hair products, cleaning supplies or spare bathroom essentials.
It’s particularly useful if you don’t have much cupboard or drawer space.
Why it’s worth considering:
- Doesn’t use floor space
- Adds lots of small storage compartments
- Useful in very small bathrooms
- Easy access to everyday items
👉 View over the door storage on Amazon here.
7. Slim Rolling Storage Cart
A narrow rolling cart can fit into surprisingly small gaps beside a sink, toilet or washing machine.
Use the shelves for toiletries, toilet rolls, cleaning supplies or towels.
Because it can be moved, it’s also useful when cleaning the bathroom.
Why it’s worth considering:
- Fits into narrow spaces
- Provides several storage levels
- Easy to move
- Doesn’t require permanent installation

8. Storage Baskets
Storage baskets are a simple way to hide bathroom clutter while keeping everything organised.
Place baskets on shelves or under the sink and use separate ones for towels, toiletries, hair products or spare supplies.
Matching baskets can also make an open storage area look much more polished.
Why it’s worth considering:
- Hide visual clutter
- Add style as well as storage
- Easy to move around
- Available in many sizes

9. Floating Shelves
Floating shelves are particularly useful when floor space is limited.
Install them above the sink, beside a mirror or on another suitable wall to create additional storage without adding bulky furniture.
Keep frequently used products on the lower shelf and less frequently used items higher up.
Why it’s worth considering:
- Uses vertical space
- Keeps counters clearer
- Works well in small bathrooms
- Can make a bathroom feel more finished

10. Stackable Storage Drawers
Small stackable drawers can be placed inside cupboards or on shelves to create additional compartments.
They’re ideal for makeup, skincare, hair accessories and other small bathroom essentials.
Clear versions are especially useful because you can see what’s inside without opening every drawer.
Why it’s worth considering:
- Creates extra compartments
- Makes small items easier to organise
- Can be rearranged as your needs change
- Great for cupboards and shelves

11. Slim Storage Cabinet
If you have a little unused floor space, a narrow bathroom cabinet can provide surprisingly generous storage.
Look for a slim design that makes use of vertical space rather than a wide cabinet that takes up valuable floor area.
Use it for towels, toiletries and spare supplies.
Why it’s worth considering:
- Adds concealed storage
- Makes use of vertical space
- Keeps products out of sight
- Useful when you don’t have built-in storage

12. Towel Storage Rack
Bulky towels can take up a surprising amount of cupboard space.
A wall-mounted towel rack or ladder-style rack can provide a dedicated place for towels while keeping them accessible.
For a small bathroom, choose a narrow design that doesn’t overwhelm the room.
Why it’s worth considering:
- Frees up cupboard space
- Keeps towels organised
- Makes use of wall space
- Can become part of your bathroom décor

13. Corner Shower Shelf
Corners are often wasted space in bathrooms, particularly inside showers.
A corner shelf can provide somewhere to store shampoo, conditioner, shower gel and other products without taking up valuable shower floor space.
Why it’s worth considering:
- Makes use of unused corners
- Keeps shower products organised
- Frees up floor space
- Useful for smaller showers
👉 View corner shelf for shower on Amazon here.
14. Toilet Roll Storage Basket
Instead of leaving spare toilet rolls on the floor or taking up valuable cupboard space, use a small basket to keep them together.
A woven or neutral-coloured basket can also add warmth and texture to an otherwise practical space.
Why it’s worth considering:
- Keeps spare rolls together
- Looks neater than loose packages
- Easy to move
- Doesn’t require installation

15. Mirrored Bathroom Cabinet
If you’re considering replacing your existing mirror, a mirrored cabinet can provide both a reflective surface and hidden storage.
It’s a particularly useful solution for small bathrooms because it combines two functions in one piece.
Use it to store everyday toiletries, skincare, medicines and other small items.
Why it’s worth considering:
- Combines a mirror and storage
- Keeps products hidden
- Makes excellent use of wall space
- Ideal for smaller bathrooms

How to Organise a Small Bathroom
Before buying lots of storage products, start by looking at what you already have.
Remove expired toiletries and products you no longer use, then group similar items together. You may be surprised by how much space you can create simply by decluttering.
Next, look for unused vertical space. Walls, the back of doors and the area above the toilet can all provide useful storage without making the floor feel crowded.
Finally, keep the things you use every day within easy reach and store less frequently used items in cupboards, baskets or higher shelves.
The goal isn’t to fill every available space with storage. It’s to make your existing space work harder while keeping the bathroom easy to use.
Small Bathroom Storage on a Budget
You don’t need to buy everything on this list. Start with the storage problem that’s causing you the most frustration.
If your bathroom counter is constantly cluttered, try drawer organisers or wall shelves. If you’re struggling with towels and spare supplies, look at baskets or vertical storage. If your shower is crowded with bottles, a shower caddy or corner shelf could make the biggest difference.
Even one or two inexpensive changes can make a small bathroom feel much more organised.
