FAQ
What do you mean by 'outdoor storage box'?
Essentially, these are plastic boxes designed to protect your garden tools, furniture cushions, or other outdoor items from the rain and sun. They’re typically made of UV-resistant polyethylene to prevent fading and cracking.
Why is material important for an outdoor box?
The type of plastic matters; look for UV-stabilised polyethylene (like PE66 or PE100) as this resists damage from sunlight. Cheaper boxes might yellow and become brittle quickly if they aren't specifically formulated for outdoor use.
Do I need a lid with hinges?
Hinged lids are preferable, allowing you to easily access the contents without having to lift the entire box. Consider the size of your tools – larger boxes will be harder to manage if they don’t have robust hinges.
What about drainage holes? Are they essential?
Drainage holes are highly recommended to prevent water from pooling inside, which could damage stored items. Ensure the holes aren't too large to avoid loose soil or debris entering the box.
Should I worry about dimensions (size)?
Absolutely – measure what you’re planning to store and choose a box that comfortably fits it, with a little extra space for air circulation. Don't buy a huge box just because it looks impressive; functionality is key.
What’s the difference between PE66 and PE100?
Both are types of polyethylene, but PE66 offers greater durability and UV resistance than PE100, making it ideal for long-term outdoor use. Check the product description to confirm which material is used.
Can I store wet items in an outdoor box?
While you can store damp tools or cushions inside, avoid prolonged exposure to moisture. Ensure proper ventilation and consider using absorbent cloths to dry items before storing them.
How do I protect the box from damage?
Store the box on a level surface and avoid stacking heavy objects on top of it. If you’re moving it frequently, use a trolley or wheelbarrow for easier handling.
What should I store *not* to put in an outdoor box?
Avoid storing highly corrosive chemicals or materials that could leach harmful substances into the box. Also, don't store items that could damage the box itself (like sharp rocks).
Where can I find information about warranty and returns?
Refer to the manufacturer’s product page for warranty details, as this varies by brand. Amazon UK handles returns according to their standard terms, which you can review on their website.
In depth
Choosing an outdoor storage box for the first time can feel a little overwhelming. There are so many options available, and it's easy to get caught up in technical details that don’t really matter if you’re just looking for somewhere to keep your garden tools or cushions safe from the rain. Let’s break down what you need to consider without getting bogged down in unnecessary complexity.
The primary function of an outdoor storage box is protection, and this starts with understanding materials. Most boxes marketed for outdoor use will be constructed from plastic – often a high-density polyethylene (HDPE) which is quite robust and weather resistant. Some may incorporate wood elements, typically treated to resist rot and dampness. Plastic is generally lighter, easier to clean, and more affordable. Wood offers a more traditional look but requires more maintenance; you’ll need to regularly treat it with a wood preservative to prevent the grain from absorbing water and causing rotting. Consider where the box will be situated – if it's constantly exposed to heavy rain, plastic is often the more sensible choice, while for a sheltered area, treated wood could be perfectly suitable. The thickness of the material can also impact durability; thicker walls generally mean greater resilience against impacts and weathering.
Next, let’s talk about size. Don’t overbuy! Measure what you actually need to store before you start looking at boxes. A small storage box (around 600-800 litres) might be sufficient for storing gardening tools like trowels, spades, and hand forks. For cushions or smaller outdoor furniture items, a medium size (1000-1500 litres) would be more appropriate. Larger boxes are available, of course, but they’re often more expensive and can be harder to manoeuvre. Think about the dimensions of your storage area and how much space you realistically need. It's always better to err on the side of slightly smaller rather than buying a huge box that sits unused most of the time.
Ventilation is another important factor, particularly if you’re storing items that are prone to dampness like cushions or blankets. Many outdoor storage boxes have vents – small openings at the top and/or sides – which allow air circulation. This helps to prevent moisture build-up and mildew growth. However, don't rely solely on ventilation; it’s still important to avoid overfilling the box, as this can restrict airflow. You can also purchase separate breathable liners designed for use in storage boxes to further assist with moisture control.
Locking mechanisms are often highlighted but their importance varies depending on what you’re storing and your security needs. Many basic outdoor storage boxes have simple clips or buckles to secure the lid. For higher-value items, a box with a robust locking system (like a padlockable clasp) might be worth considering, but don't let this be the primary driver of your purchase – a good quality, well-sealed box is often sufficient for protecting against theft by opportunistic passersby.
Finally, consider drainage. Look for boxes with holes in the base to allow any water that does seep in to drain away. This prevents the accumulation of standing water, which can damage stored items and promote mould growth. The presence or absence of a plastic liner inside the box is also worth noting – liners can add an extra layer of protection but may not be suitable for all materials. It's often better to simply use breathable fabric bags within the box to contain smaller items. Don’t get hung up on fancy features like wheels or integrated shelving unless you specifically need them; these will add to the cost and complexity without providing a significant benefit for basic outdoor storage.
