10 Clever Storage Ideas for a Small Bathroom
Small bathrooms can quickly become cluttered, but overlooked spaces can provide useful storage even when floor space is limited. These 10 practical ideas help you organise toiletries, towels and everyday essentials using awkward gaps, unused walls, the space beneath the sink and behind doors.

1. Make better use of the space under your sink
The cupboard beneath a bathroom sink can offer surprisingly useful storage, but pipes and plumbing often make it an awkward space to organise. Instead of filling it with loose bottles and cleaning products, use smaller containers or organisers to make better use of the available height and width.
Stackable drawers, baskets and tiered organisers can help separate toiletries, spare bathroom supplies and cleaning products while keeping frequently used items easy to reach. If pipework gets in the way, look for adjustable or narrow organisers that can fit around it rather than trying to fill the entire cupboard with one large unit.
Look for:
- Two tiers to make better use of vertical space
- A design that works around existing pipework
- Pull-out or sliding storage for easier access
- Enough space for toiletries and cleaning products
- A size that fits comfortably inside your bathroom cabinet
A practical under-sink storage option
SONGMICS Two-Tier Under-Sink Organiser
If you want to make better use of the height inside a bathroom cupboard, a two-tier organiser can provide extra storage without taking up additional floor space.
- Product details:
- The SONGMICS two-tier under-sink organiser has an adjustable frame and a sliding lower drawer, making it easier to reach bottles and other bathroom essentials stored towards the back of the cupboard. Its open design also leaves space around the shelving, which can be useful when working around pipework.
2. Make use of narrow gaps with a slim storage trolley
Bathrooms often have awkward gaps beside the sink, bath, shower or bathroom furniture that aren’t quite large enough for a cupboard. A slim storage trolley can turn one of these otherwise unused spaces into useful storage without taking up much floor space.
A tiered trolley is particularly handy for keeping toiletries, spare toilet rolls, cleaning products and other bathroom essentials together. Choosing one on wheels also makes it easy to pull out when you need something and tuck away again afterwards.
Bathrooms often have awkward gaps beside the sink, toilet, bath or bathroom furniture that aren’t quite large enough for a cupboard. A slim storage trolley can turn these otherwise unused spaces into useful storage without taking up much additional floor space.
A tiered trolley can be particularly useful for keeping everyday bathroom essentials together while still making them easy to reach.
Look for:
- A narrow design that fits otherwise unused gaps
- Several tiers to maximise vertical storage
- Wheels so the trolley can easily be pulled out
- Shelves suitable for toiletries, spare toilet rolls and cleaning products
- A width that suits the particular space available
Our pick: The VASAGLE 4-Tier Slim Storage Trolley provides four levels of storage while keeping a relatively narrow footprint. It’s also available in different widths, which is useful when you’re trying to make the most of a particularly tight bathroom space.
A practical slim storage trolley for the bathroom
VASAGLE 4-Tier Slim Storage Trolley
The VASAGLE 4-Tier Slim Storage Trolley provides four levels of storage while keeping a relatively narrow footprint. Its wheeled design means it can be pulled out when you need something and tucked back into a narrow space afterwards.
- Product details:
- It’s available in different widths, which makes it useful for bathrooms where the available gap may be particularly tight. The shelves can be used for toiletries, spare toilet rolls, cleaning supplies and other smaller bathroom essentials.
3. Make use of the space above the toilet
In a small bathroom, some of the most useful storage space can be found above existing fixtures. The wall area above the toilet is often left completely empty, even though it can provide room for everyday bathroom essentials without taking up any additional floor space.
An over-toilet storage unit can provide several shelves while keeping the area immediately around the toilet clear.
Look for:
- A freestanding design that fits around the toilet
- Several shelves for making use of vertical space
- Enough clearance for your particular toilet and cistern
- Storage for spare towels, toilet rolls and toiletries
- A stable design that can be securely positioned or fixed as instructed by the manufacturer
A simple way to add storage above the toilet
Over Toilet 3-Tier Storage Rack
An Over Toilet 3-Tier Storage Rack makes use of the otherwise empty space above the toilet without taking up additional floor space. The three shelves provide room for items such as spare toilet rolls, folded towels, toiletries and small storage baskets.
- Product details:
- Its freestanding design also makes it a relatively simple option for smaller bathrooms where adding another cupboard or storage unit isn’t practical. As with any over-toilet unit, it’s worth checking the dimensions carefully before ordering to make sure there’s sufficient clearance around your particular toilet and cistern.
4. Make use of empty wall space
In a small bathroom, the walls are often one of the most underused storage areas. Adding a compact shelf or shower basket can move everyday toiletries away from the basin, bath edge or windowsill without taking up any additional floor space.
Look for:
- A compact design that doesn’t protrude too far into the room
- Moisture-resistant materials suitable for bathrooms
- Raised edges or a basket-style design to stop bottles falling
- Good drainage if it will be positioned inside the shower
- No-drill fixing if you’d rather avoid making holes in tiles
A simple wall-mounted storage solution
Orimade Shower Caddy 2-Pack
The Orimade Shower Caddy 2-Pack provides two wall-mounted baskets for keeping toiletries off worktops and bath edges. The adhesive fixing means there’s no need to drill into bathroom tiles, while the open wire design allows water to drain away.
- Product details:
- The additional hooks are useful for smaller items such as shower sponges, brushes or razors, making better use of wall space without adding another piece of furniture.
5. Organise drawers with small storage trays
Bathroom drawers can become cluttered surprisingly quickly, particularly when smaller items such as cosmetics, razors, hair accessories and toiletries are mixed together. Dividing the drawer into smaller sections makes it easier to see what you have and prevents everyday essentials disappearing underneath everything else.
Look for:
- Several tray sizes that can be arranged to suit the drawer
- Shallow containers that don’t waste vertical space
- Smooth, wipe-clean materials
- Separate compartments for smaller toiletries and accessories
- A modular design that can be rearranged as your storage needs change
Keep small bathroom essentials organised
Radikor 16-piece Drawer Organiser Set
A set of clear storage trays can turn a cluttered bathroom drawer into a much more usable space. Different-sized compartments make it easier to separate cosmetics, grooming products, hair accessories and other small items while keeping everything visible.
- Product details:
- The Radikor 16-piece Drawer Organiser Set includes four different tray sizes, so the layout can be arranged to suit the drawer and changed later if needed. The transparent, wipe-clean design also works particularly well in a bathroom.
6. Use baskets to organise open shelving
Open bathroom shelves are useful, but rows of toiletries, spare products and cleaning supplies can quickly make them look cluttered. Small baskets let you group similar items together while keeping the shelves looking tidy.
They can also make deeper shelves easier to use because the whole basket can be pulled out rather than having to reach behind whatever is at the front.
Look for:
- Baskets sized to fit your existing shelves
- Handles or cut-out grips for easy access
- Wipe-clean or moisture-resistant materials
- A reasonably uniform shape so several baskets sit neatly together
- Different sizes for toiletries, toilet rolls, towels and smaller bathroom items
Keep open shelves tidy with storage baskets
Straame Seagrass Storage Baskets
The Straame Seagrass Storage Baskets come as a matching set of four, making them useful for grouping toiletries, spare bathroom products and other essentials on open shelving.
- Product details:
- Each basket measures approximately 30 × 22 × 15 cm and combines natural woven seagrass with a reinforced steel frame. The inset handles also make the baskets easy to pull from a shelf when you need something stored towards the back.
Their neutral woven finish works particularly well if you want practical storage without making open bathroom shelving look overly utilitarian.
7. Make use of the shower door
The shower itself can provide useful storage space, particularly in a small bathroom where there may be little room for additional furniture or shelving. An organiser that hangs over the top of a glass shower door can turn this otherwise unused space into an accessible place for everyday toiletries.
Look for:
- A design specifically suitable for glass shower doors
- Several tiers for shampoo, conditioner and shower products
- Good drainage so water does not collect in the baskets
- Hooks for loofahs, razors or small towels
- Protective padding where the organiser contacts the glass
- A stable design that will not swing when items are removed
A practical over-glass shower organiser
SONGMICS 3-Tier Hanging Shower Caddy
The SONGMICS 3-Tier Hanging Shower Caddy is a useful example for bathrooms where storage space is limited. It hangs over the top of a glass shower door without requiring drilling or adhesive, providing three storage baskets for bottles and other shower essentials.
- Product details:
- The baskets have an open design to allow water to drain away, while suction cups help hold the organiser against the glass and reduce movement. There are also hooks for smaller accessories such as loofahs, razors and towels.
Made from powder-coated steel, it is designed for use in a damp bathroom environment. At approximately 32.8 × 17 × 69.3 cm, the three-tier arrangement makes good use of vertical space without taking up additional floor space.
Before buying: Check the thickness and clearance around your shower door to make sure an over-glass organiser will fit correctly and will not interfere with the door opening or closing.
8. Use a mirrored bathroom cabinet
In a small bathroom, it makes sense for one item to do more than one job. Replacing a standard wall mirror with a mirrored cabinet gives you useful hidden storage without taking up any additional floor space.
It can be particularly handy for keeping everyday toiletries and smaller items off the basin and worktops, helping the room feel less cluttered.
Look for:
- A slim design that doesn’t protrude too far from the wall
- Adjustable shelving for different-sized toiletries
- Enough internal space for frequently used bathroom essentials
- A size that works comfortably above your basin
- A finish that suits the rest of the bathroom
- Suitable wall fixings for the surface you’re mounting it to
A compact mirrored storage option
Taylor & Brown Single Door Mirrored Bathroom Cabinet
The Taylor & Brown Single Door Mirrored Bathroom Cabinet is a good example of this type of space-saving storage. At approximately 34 cm wide × 15 cm deep × 53 cm high, it’s relatively compact while still providing concealed storage behind the mirrored door.
- Product details:
- The adjustable internal shelf lets you organise toiletries, medicines or other smaller bathroom items at different heights, while the built-in mirror means you’re making practical use of wall space that might otherwise hold only a standard mirror.
9. Add storage inside cupboard doors
The inside of a bathroom cupboard door is easily overlooked, but it can provide useful extra storage without taking up any additional floor or shelf space.
Small baskets attached to the inside of the door are particularly useful for everyday toiletries, cleaning products and other smaller items that can otherwise leave cupboards feeling cluttered.
Look for:
- A shallow design that still allows the cupboard door to close
- Secure fixings suitable for the weight you intend to store
- No-drill installation if you don’t want to damage the cupboard
- Moisture-resistant materials suitable for bathroom use
- Baskets deep enough to keep bottles securely in place
- A position that won’t interfere with shelves, hinges or plumbing
A simple way to use hidden cupboard space
Josmimic 2 Pack Cupboard Door Storage Baskets
The Josmimic 2 Pack Cupboard Door Storage Baskets are designed to make use of otherwise wasted space inside cupboard doors.
- Product details:
- The two black metal baskets measure approximately 23.8 × 8.3 × 15 cm each and use self-adhesive mounting rather than requiring holes to be drilled. Their relatively shallow depth makes them particularly suitable for storing smaller bottles, toiletries and cleaning products while keeping the main cupboard shelves free for larger items.
The set also includes hooks, providing somewhere to hang smaller accessories such as brushes where appropriate.
10. Store rolled towels on the wall
Towels can take up a surprising amount of cupboard and shelf space, especially in a small bathroom. A wall-mounted towel rack lets you use otherwise empty vertical space while keeping clean towels organised and within easy reach.
Rolling the towels rather than folding and stacking them can also make a narrow vertical rack practical without requiring a deep shelf or cupboard.
Look for:
- A slim design that makes good use of vertical wall space
- Enough depth to hold rolled towels securely
- A capacity suitable for the size of towels you normally use
- Moisture-resistant materials suitable for a bathroom
- Secure wall fixings, particularly when storing several larger towels
- A position where the rack won’t obstruct doors, cupboards or other bathroom fittings
A space-saving wall-mounted towel rack
XIAPIA Wall Mounted Towel Rack
The XIAPIA Wall Mounted Towel Rack provides vertical storage for rolled towels while taking up relatively little wall space.
- Product details:
- Its three-bar metal design helps support the towels and prevent them from slipping out, while the approximately 75 cm height provides room for several rolled towels depending on their size.
The listing shows the rack in a silver finish and gives approximate dimensions of 15 × 19.1 × 74.9 cm. It can therefore be particularly useful in a smaller bathroom where cupboard space is limited but an unused section of wall is available.
The manufacturer lists both screw and adhesive installation options. For heavier loads, it’s worth choosing a fixing method appropriate for the wall surface and following the manufacturer’s installation instructions.
Make the most of the space you have
A small bathroom doesn’t necessarily need more storage furniture — often, it’s simply a case of making better use of the space that’s already there.
Look under sinks, inside cupboard doors, above existing furniture and at unused wall space before adding anything that takes up valuable floor area. Even small changes, such as organising a drawer or adding a couple of baskets, can make everyday items easier to find and help the room feel less cluttered.
You don’t need to use every idea on this list. Start with the areas that cause the most frustration and choose the storage solutions that suit your bathroom, your available space and the things you actually need to store.
A few well-chosen changes can make even a compact bathroom feel calmer, tidier and much easier to use.
