A normal garden storage box is fine for cushions and patio clutter, but lawn mowers and garden tools need something more practical.
If you are storing a mower, lawn feed, hose fittings, sprayers, scarifier accessories, gloves, hand tools and bags of compost, the shape of the storage matters just as much as the capacity. A deep cushion box can look big on paper but still be awkward for mower storage or regular tool access.
For most UK gardens, the best garden storage for lawn mowers and garden tools is a shed-style outdoor storage unit rather than a standard deck box. You want decent access, a lockable design, enough internal height, and enough floor space for bulky garden kit.
This guide compares the best garden storage options for lawn mowers, tools, lawn care products and outdoor equipment.
If you are still choosing the equipment itself, read my guides to the best lawn mower UK, best lawn scarifier UK and best lawn fertiliser UK before deciding how much storage space you actually need. I’ve also compared the best lawn mowers for stripes, including rear roller electric, cordless and petrol options.
Quick Answer: Best Garden Storage for Lawn Mowers and Garden Tools UK
For most people, I would start with the Keter Store It Out Pro. It is the most useful all-round option for garden tools, lawn feed, hose fittings, mower accessories and general lawn care storage.
If you need more space, the Keter Store It Out Ultra is the better premium choice because it gives more capacity for bulky garden kit, bins, mower accessories and larger bags.
If you want a non-Keter alternative, the Duramax StoreAway 850L is worth considering as a shed-style storage unit for tools and general outdoor kit.
If you only need somewhere for small hand tools, gloves, hose fittings and light accessories, a smaller box such as the Amazon Basics 375L or Keter Marvel+ may be enough, but I would not choose those as proper mower storage.

What Type of Storage Do Lawn Mowers and Garden Tools Need?
Lawn mowers and garden tools need different storage from cushions.
Cushions are light and bulky. Tools are awkward, dirty and often sharp. Lawn feed needs to be kept dry. Sprayers need to stay upright. Hose fittings and small accessories are easy to lose. Cordless mower batteries should not be left somewhere damp or exposed to extreme temperatures.
That means the best storage is usually:
- Wide enough for mower accessories
- Tall enough for awkward garden kit
- Easy to open from the front
- Lockable
- Weather-resistant
- Positioned on a firm, level base
- Easy to access regularly
- Large enough without dominating the garden
A standard deck box can work for small tools, but once you are storing lawn care equipment, a shed-style unit is usually better.
Best Overall: Keter Store It Out Pro
The Keter Store It Out Pro is the storage unit I would choose first for most people who want somewhere practical for lawn tools and garden kit.
It makes more sense than a normal cushion box because it is designed more like a small outdoor store. That gives better access for bags of lawn feed, hosepipes, spreaders, sprayers, mower accessories, folded covers, compost bags and general garden equipment.
For a Formby Gardener reader, this is the most relevant product on the list. It bridges directly from lawn care into outdoor storage. If you have a mower, scarifier, lawn fertiliser, garden sprayer, hose fittings and hand tools, this type of unit is far more useful than a low patio box.
The main advantage is access. With a deep box, everything tends to get piled on top of everything else. With a shed-style storage unit, you can get to tools and products more easily.
It is not a full shed, and I would not pretend it is. But for many small to medium UK gardens, it gives enough practical storage without needing a large timber shed.
Best for:
- Lawn feed
- Garden tools
- Hosepipes and fittings
- Sprayers
- Mower accessories
- Small lawn care kit
- Bags of compost
- General garden equipment
Not ideal for:
- Very small patios
- Full-size mower storage without checking dimensions
- Long-handled tools unless they fit your layout
- People who need a walk-in shed
- Expensive tools that need higher-security storage
Best Premium Storage: Keter Store It Out Ultra
The Keter Store It Out Ultra is the step-up option if you need more serious outdoor storage.
This is the one I would look at if the Pro does not give enough capacity. It is better suited to bulkier garden kit, larger bags, bins, mower accessories, outdoor toys, folded covers and general storage where a normal garden box is too limiting.
The Ultra makes sense if you are trying to avoid buying a full shed but still need something more substantial than a deck box.
It is especially useful if you want one storage unit to hold a mixture of items:
- lawn feed
- compost bags
- hose reels
- mower accessories
- garden tools
- outdoor toys
- bins
- patio covers
The trade-off is size and price. This is not the right choice if you only need to store a few hand tools or one small bag of lawn feed. It is for people who have outgrown a normal box.
Best for:
- Larger garden kit
- Bulkier storage
- Mower accessories
- Bin storage
- Compost and lawn feed bags
- Families with lots of outdoor equipment
- People who want a shed-style unit without a full shed
Not ideal for:
- Small patios
- Budget buyers
- Simple cushion storage
- Very small tool collections
Best Lower-Cost Shed-Style Option: Keter Store It Out Midi
The Keter Store It Out Midi is a good option if you want the shed-style layout but do not need the size or cost of the larger units.
This is useful for smaller gardens where a full-size storage unit would dominate the space. It can work for hand tools, lawn feed, hose fittings, watering accessories, gloves, smaller garden products and light mower accessories.
It is not the one I would choose for serious mower storage, but it can be a practical middle ground for people who need something more useful than a standard box.
Best for:
- Smaller gardens
- Light garden tool storage
- Lawn feed and accessories
- Hose fittings
- Watering kit
- Buyers wanting shed-style access on a smaller scale
Not ideal for:
- Full mower storage
- Large lawn care equipment
- Long-handled tools
- Bulk compost or large storage loads
Best Small Accessories Box: Amazon Basics 375L Garden Storage Box
The Amazon Basics 375L Garden Storage Box is not proper mower storage, but it is useful for smaller lawn care accessories.
I would use this type of box for the items that always go missing: gloves, sprinkler fittings, hose connectors, small tools, folded covers, plant ties, kneeling pads, lawn spreader accessories and smaller garden products.
It can also work well alongside a larger shed-style unit. Use the big unit for mower accessories and lawn care kit, then use a smaller box for clean, lightweight items you reach for often.
This is a good option if you already have a shed but need extra outdoor storage near the patio or lawn.
Best for:
- Hand tools
- Gloves
- Hose fittings
- Small accessories
- Folded covers
- Light garden storage
- Patio clutter
Not ideal for:
- Lawn mowers
- Scarifiers
- Long-handled tools
- Large bags of compost
- Heavy equipment
Best Budget Compact Box: Keter Marvel+ 270L
The Keter Marvel+ 270L is a compact budget option for small gardens and light tool storage.
It is not a mower storage solution. It is not a shed replacement. But for the right job, it is useful.
Choose this if you only need somewhere for smaller tools, gloves, secateurs, a hand fork, hose fittings, plant labels, folded covers or a few small garden accessories.
For small patios, it is often better to buy a compact box you will actually use rather than squeezing in a storage unit that is too large for the space.
Best for:
- Small gardens
- Budget storage
- Hand tools
- Gloves and accessories
- Hose fittings
- Light patio storage
Not ideal for:
- Lawn mowers
- Scarifiers
- Large tools
- Bags of lawn feed
- Serious equipment storage
Best for Tiny Patios: Keter City
The Keter City is the small-space option.
It is only suitable for light storage, but that is the point. Not everyone needs a large outdoor unit. If you have a tiny patio, balcony or very small garden, a small storage box can still be useful.
It can work for:
- gloves
- secateurs
- hand tools
- hose connectors
- small toys
- plant labels
- twine
- small accessories
I would not buy it for lawn care storage. It is too small for that. But for keeping a tiny patio tidy, it makes sense.
Best for:
- Tiny patios
- Balconies
- Small accessories
- Light tools
- Very limited space
Not ideal for:
- Lawn mowers
- Lawn feed
- Sprayers
- Long-handled tools
- Bulky garden kit
Best Alternative to the Pro: Keter Store It Out Max
The Keter Store It Out Max is another practical shed-style option and worth considering alongside the Pro.
It fits the same broad use case: garden tools, lawn care products, hosepipes, accessories, smaller equipment and general outdoor kit.
If the Pro is unavailable, overpriced, or the dimensions do not suit your space, the Max is a sensible alternative to check.
Best for:
- General lawn and garden kit
- Mower accessories
- Hosepipes
- Lawn feed
- Garden tools
- People comparing against the Store It Out Pro
Not ideal for:
- Full shed replacement
- Very small patios
- Long-handled tools unless checked carefully
- High-security tool storage
Can You Store a Lawn Mower in Garden Storage?
Sometimes, but you need to check the dimensions properly.
Do not assume a mower will fit just because the storage unit looks big in the photos. Lawn mowers are awkward because of the handle, wheels, cutting deck and height.
Before buying storage for a mower, check:
- Internal width
- Internal depth
- Internal height
- Door opening width
- Whether the mower handle folds
- Whether the mower needs lifting in
- Whether the floor can cope with the weight
- Whether there is room for accessories
For small cordless mowers, a shed-style storage unit may work. For larger petrol mowers or heavy professional mowers, I would usually look at a proper shed or garage space instead.
If you are storing a cordless mower, remove the battery and keep it somewhere dry and sensible. I would not leave batteries in a damp outdoor box.
What About Robot Lawn Mowers?
Robot mowers are different.
A robot mower usually needs either:
- a dedicated robot mower garage
- a sheltered docking station
- suitable weather protection
- cable access if it uses a charging base
A normal garden storage box is not usually the right solution if the mower needs to dock and charge automatically.
If you are storing the robot mower over winter, a dry indoor or secure storage space is usually better. Clean it first, check the manufacturer guidance and avoid leaving batteries somewhere damp or freezing.
For robot mower buying advice, read my guide to the best robot lawn mowers for UK gardens.
Can You Store Lawn Feed and Weedkiller Outside?
You can store lawn feed outside, but it needs to be kept dry, sealed and secure.
Fertiliser absorbs moisture. Once it gets damp, it can clump together and become difficult to spread evenly. That matters because uneven fertiliser application can leave stripes, patches or scorch marks on the lawn.
For lawn feed, I would do one of the following:
- keep it sealed in its original bag
- place the bag inside a lidded plastic tub
- store the tub inside a dry storage unit
- avoid placing bags directly on a damp floor
- keep it away from children and pets
Weedkillers, moss killers and other garden chemicals should always be stored according to the label. Keep them upright, secure and away from children and pets.
For garden chemicals, a lockable cabinet or secure storage unit is better than a loose open box.
Garden Storage Box vs Shed-Style Unit
A garden storage box is best for light, clean and bulky items.
A shed-style unit is better for tools, lawn care kit and awkward equipment.
Choose a garden storage box for:
- gloves
- hand tools
- cushions
- covers
- hose fittings
- small accessories
- folded patio items
Choose a shed-style unit for:
- lawn feed
- sprayers
- hose reels
- mower accessories
- bags of compost
- garden tools
- bins
- bulkier outdoor kit
If you are serious about lawn care, the shed-style unit is usually the better choice.
Where Should You Put Garden Storage?
Put garden storage on a firm, level base.
A patio, paving slab base, decking area or prepared gravel base is usually better than sitting the box straight on the lawn. Grass and soil can stay damp, shift underneath the unit and make doors or lids harder to open.
Before positioning the unit, check:
- the lid can open fully
- the doors have clearance
- it is not blocking access
- water does not pool underneath
- it is not in the way of mowing
- it is close enough to be useful
Storage that is awkward to reach will not get used properly.
What to Store Inside a Lawn and Tool Storage Unit
A good garden storage setup can hold:
- lawn feed
- grass seed
- gloves
- hand tools
- hose fittings
- sprinkler parts
- sprayers
- spreaders
- mower accessories
- scarifier cartridges or parts
- folded covers
- compost bags
- kneeling pads
- secateurs
- edging tools
- small repair items
Keep sharper tools protected and avoid throwing everything loose into one space. A few small tubs inside a larger storage unit can make a big difference.
Common Mistakes When Buying Garden Storage for Tools
Buying a Cushion Box for Tool Storage
Cushion boxes are fine for cushions. They are not always good for tools, lawn feed or mower accessories.
Ignoring the Door Opening
A storage unit can look large but still have an awkward opening. Check the door or lid access before buying.
Forgetting About the Mower Handle
Mower handles take up space even when folded. Measure properly.
Storing Fertiliser Loose
Lawn feed needs to stay dry. Keep it sealed and ideally inside another container.
Leaving Cordless Batteries Outside
Cordless mower and tool batteries should be protected from damp and extreme temperatures.
Buying Too Small
Small boxes look tidy but fill quickly. Lawn care kit takes more room than people expect.
Buying Too Big
A huge storage unit can dominate a small garden. Match the storage to the space.
My Verdict: Which Garden Storage Should You Buy?
For most UK gardens, I would choose the Keter Store It Out Pro as the best overall storage option for lawn mowers, garden tools and lawn care kit.
It gives a more practical layout than a standard deck box and is better suited to the sort of equipment gardeners actually need to store: lawn feed, hose fittings, sprayers, small tools, compost bags and mower accessories.
If you need more space, move up to the Keter Store It Out Ultra.
If you only need storage for small tools and accessories, the Amazon Basics 375L or Keter Marvel+ may be enough.
The key point is simple: buy for the items you actually need to store. A mower, lawn feed and garden tools need a different storage solution from cushions and patio blankets.
