Keter 150L Store-It-Out
Best OverallPros
- Excellent capacity for the price
- UV-resistant and weatherproof
- Lightweight and easy to move
Cons
- Lid could be sturdier
- Not lockable out of the box
The Keter 150L Store-It-Out is a popular choice for good reason. It offers a generous 150-litre capacity, enough for several garden cushions, small tools, and pots. The resin construction is UV-resistant and weatherproof, so it holds up well in direct sunlight and rain. Owner reviews consistently praise its value for money and ease of assembly.
Some users note the lid feels a bit flimsy when fully loaded, but it is adequate for general use. It does not come with a lock, but you can add a padlock through the built-in hasp. For a balance of size, durability, and cost, this is the best outdoor storage box under £200.
Suncast 100L Resin Deck Box
Best BudgetPros
- Very affordable price point
- Compact and space-saving
- Good weather resistance
Cons
- Smaller capacity limits use
- Not as sturdy as larger models
The Suncast 100L Resin Deck Box is an excellent entry-level option. It is compact enough for small patios or balconies and can hold a few cushions, toys, or gardening supplies. The resin material is weather-resistant and easy to clean. Owner reviews highlight its low price and simple assembly as major pluses.
Its smaller size means it is not ideal for large tools or multiple items. The plastic hinges are a common point of complaint in reviews, but for the price, it is hard to beat. This is the best budget pick for those who need basic storage without spending much.
Bosch 120L Garden Storage Box
Best for ToolsPros
- Strong build from a trusted brand
- Good for storing power tools
- 2-year warranty
Cons
- Plastic may fade in direct sun
- Lid does not stay open
The Bosch 120L Garden Storage Box is designed with tool storage in mind. It has a sturdy plastic construction that can handle heavier items like drills, saws, and garden tools. The 120-litre capacity is a good middle ground, and the Bosch brand is known for reliability. Owner reviews often mention the box feels solid and secure.
One downside is the plastic material can fade over time if left in constant sunlight. The lid also does not have a stay-open mechanism, which can be annoying when accessing items. Still, for tool storage specifically, this is a dependable choice under £200.
Keter 300L Factor 6.0
Best Large CapacityPros
- Huge 300L capacity
- Very high weight rating
- Durable resin construction
Cons
- Large footprint needs space
- Assembly can be time-consuming
The Keter 300L Factor 6.0 is the largest box in this roundup. It is ideal for storing bulky items like large garden cushions, pots, or even a small lawnmower. The resin material is strong and weather-resistant, and the 300kg weight rating means it can handle heavy loads. Owner reviews appreciate the sheer size and value for money.
Its main drawback is the size: it requires a significant amount of floor space. Assembly is also more complex than smaller boxes, taking around 30-45 minutes. If you have the room and need maximum capacity, this is the best choice under £200.
Stanley 90L Storage Box
Best for DurabilityPros
- Very rugged and tough build
- Good for heavy tools
- Reliable brand reputation
Cons
- Smaller capacity than others
- Plain design, not as stylish
The Stanley 90L Storage Box focuses on durability above all else. It is made from heavy-duty plastic that feels more robust than standard resin boxes. This makes it a great choice for storing heavy tools or equipment that needs extra protection. Owner reviews often note the box feels very solid and can withstand rough handling.
The trade-off is a smaller 90-litre capacity, which limits what you can store. The design is also purely functional, lacking the aesthetic appeal of some other boxes. For those who prioritise strength over size, this is a top contender under £200.
What to check before buying an outdoor storage box under £200
Choosing the right storage box involves more than just picking the cheapest option. Here are the key factors to consider.
Material: Resin is the most common material at this price. It is lightweight, weather-resistant, and UV-protected. Basic plastic is cheaper but can fade and crack over time. Wood and metal options are rare under £200 and often lack the same weatherproofing.
Capacity: Think about what you need to store. A 100L box is good for cushions and small tools. A 300L box can hold large pots or a lawnmower. Measure your space before buying to ensure the box fits.
Weight rating: This tells you how much weight the lid and base can support. A higher rating means the box is more durable. Look for at least 150kg for general use.
Weather resistance: Check if the box has UV protection to prevent fading. Also look for a water-resistant seal on the lid to keep contents dry.
Mistakes to avoid when buying an outdoor storage box
Many buyers make these common errors. Avoid them to get the best value.
Ignoring assembly requirements: Some boxes require significant assembly. Check reviews for assembly difficulty and time. You may need a screwdriver or drill.
Forgetting about locks: Most boxes under £200 do not come with a lock. If security is important, look for a model with a built-in hasp for a padlock.
Choosing style over substance: A box that looks good but is made of thin plastic will not last. Prioritise material and weight rating over appearance.
