Best Plastic Garden Storage Containers for Patios and Outdoor Spaces
The best plastic garden storage container depends on how much space you need and what you plan to store. The Devoko 100-gallon deck box is best for bulky cushions and equipment, while the Devoko 30-gallon box is a compact choice that can also serve as a seat. For small patios, consider the Keter Kentwood 50-gallon box or Keter City 30-gallon side table. The 35-gallon lockable box suits buyers who want portable storage with a lockable lid.
| Product | Capacity | Best suited for |
|---|---|---|
| 35 Gallon Lockable Deck Box | 35 gallons | Portable, lockable storage |
| Devoko Waterproof Deck Box | 100 gallons | Large outdoor items |
| Devoko Resin Deck Box | 30 gallons | Compact storage and extra seating |
| Keter Kentwood Storage Box | 50 gallons | Smaller patios and everyday essentials |
| Keter City Storage Box | 30 gallons | Small storage with side-table use |
35 Gallon Lockable Outdoor Deck Box
This 35-gallon container is best for buyers who want a movable box for patio cushions, garden tools, or pool accessories. Its lid is described as tight-sealing, and the listed features include resistance to rain and humidity. UV-resistant materials are also intended to help limit fading and weather damage.
Built-in handles make the box easier to move, and its lockable design can help secure stored items. It is a practical middle-ground choice when a 30-gallon box seems too small but a 100-gallon container would take up too much room.
- Best for: Portable outdoor storage with a lockable lid.
- Limitation: The lock is not included, so a separate lock is needed to use that feature.
Devoko 100 Gallon Waterproof Deck Box
Choose this Devoko box if storage capacity is your main priority. At 100 gallons, it offers the largest stated capacity in this group and is suited to patio cushions, tools, and other outdoor equipment. Its listed interior dimensions are 47.8 inches long, 21.4 inches wide, and 24.6 inches high, which can help shoppers check whether the box will fit their intended space.
The poly-resin construction is described as weather-resistant and waterproof. Its rattan-style pattern gives it a decorative appearance for a deck, yard, porch, or poolside area. This is a better choice for large storage needs than the smaller boxes, but the stated dimensions mean it requires more room.
- Best for: Storing larger or multiple outdoor items.
- Limitation: Measure the placement area before choosing this large-capacity model.
Devoko 30 Gallon Resin Deck Box
This compact Devoko container is best for buyers who want storage and an occasional extra seat. The product information says it can support up to 220 pounds and has a 20-inch height. Its high-density resin is described as stable, waterproof, and UV-resistant, while the 8.8-pound net weight and built-in armrest make it easier to move.
The box can be locked, making it useful for keeping small outdoor supplies contained. Choose it over a basic storage container if the seating feature matters as well as storage. Its 30-gallon capacity is more limited than the 50- and 100-gallon options, so it is better for a smaller collection of items.
- Best for: Compact storage that can also provide extra seating.
- Limitation: Its 30-gallon capacity may not suit bulky cushions or many items.
Keter Kentwood 50 Gallon Storage Box
The Keter Kentwood is best for shoppers who need more room than a compact 30-gallon box provides but do not want the largest option. Its 50-gallon capacity is intended for everyday outdoor items such as dining cushions, pool accessories, beach towels, and garden supplies. The product is described as suitable for balconies, patios, porches, and garage areas.
Its weather-resistant resin is listed as resistant to rusting, peeling, fading, and denting. That makes it a practical choice for buyers seeking low-maintenance outdoor storage. The available product details do not specify a lock or a waterproof seal, so choose another option if either feature is essential.
- Best for: Everyday storage in a relatively compact outdoor space.
- Limitation: Locking and waterproof-seal details are not provided.
Keter City 30 Gallon Storage Side Table
This Keter City model is best for small patios where a storage container can also serve as a side table. It has 30 gallons of storage and an all-weather-resistant resin construction with a wood-look texture. Its exterior dimensions are 22.75 inches long, 17.3 inches wide, and 21.7 inches high; the interior measures 22.71 by 16.3 by 20.3 inches.
The defined interior measurements help buyers compare the box with the items they plan to store. Its capacity is suited to smaller accessories rather than large cushion sets. The listed features describe weather resistance, but do not specify a waterproof seal or locking mechanism.
- Best for: Small spaces where a side-table function is useful.
- Limitation: The 30-gallon capacity is modest for bulky outdoor gear.
Buying Guide: How To Choose A Plastic Garden Storage Container
How much storage capacity do you need?
Compare the capacity with the size and number of items you plan to store. The 30-gallon boxes suit smaller accessories, while the 50-gallon Kentwood offers more room for everyday patio supplies. Choose the 100-gallon Devoko for a larger collection. For cushion storage, check the container’s interior dimensions against the cushions rather than relying on capacity alone.
Does the box need to be waterproof or weather-resistant?
These terms are not interchangeable in the product details. The 35-gallon box is described as having a tight-sealing lid and protection against rain and humidity; the Devoko models are described as waterproof. The Keter products are described as weather-resistant, but their listed features do not specify a waterproof seal. Match the description to your exposure and storage needs.
Will it fit your space and serve another purpose?
Measure the planned location before ordering, especially for a high-capacity box. Consider whether a side-table surface or extra seat would be useful. The Devoko 30-gallon model is specifically described as supporting up to 220 pounds when used as a seat. Do not assume other boxes are seating unless their product details say so.
Is a lock important?
Two options list a lockable design: the 35-gallon box and the Devoko 30-gallon model. The 35-gallon model does not include a lock. If you need a lock, check how the container accepts one and whether you must supply it separately.
