230 vs 380 Gallon Deck Box Specs
Storage Capacity
Capacity is the primary difference between these two resin deck boxes. Product A, the KAMABOKO 230 Gallon Resin Deck Box, offers 230 gallons of interior volume. This size is suitable for patio cushions, garden tools, and pool supplies. Product B, the ATMELT 380 Gallon Resin Deck Box with Support Rod, provides 380 gallons of space. This larger capacity allows you to store more items, such as larger outdoor furniture sets or extensive seasonal decorations. If you need to maximize your storage volume, the 380-gallon option holds significantly more. The extra 150 gallons can make a practical difference in keeping your deck or backyard clutter-free.
Exterior Dimensions
Size and footprint matter for placement on your patio or deck. Product A measures 60.8 inches in length, 28.4 inches in width, and 29.2 inches in height. These dimensions create a relatively compact profile. Product B is larger, measuring 68.7 inches in length, 33.2 inches in width, and 34.7 inches in height. The ATMELT box is wider and taller, which contributes to its greater capacity but requires more floor space. You should measure your available area before deciding. If space is limited, the smaller footprint of the 230-gallon box may fit better. However, if you have ample room, the larger box offers more utility.
Material Construction
Both units are built from durable resin, which is resistant to rust, dents, and peeling. Product A is made from general resin, described as waterproof and UV-resistant. This protects your items from rain, moisture, and fading. Product B is constructed from polypropylene resin, a tough plastic that also offers water resistance and UV protection. The key distinction is the specific resin type. Polypropylene is often noted for high durability and impact resistance. Both materials ensure your storage box withstands outdoor conditions without maintenance. You do not need to paint or seal either unit. The waterproof feature in both models keeps your stored items dry.
Lid Features
The lid design affects usability and security. Product A includes a lockable lid, which helps keep outdoor essentials secure from unexpected access. It also features a removable divider inside, allowing you to separate compartments for sorting items like garden tools from pool supplies. Product B includes a support rod for the lid, which likely helps keep the lid open when you are accessing items. It does not mention a lock or an internal divider. If security and organization are priorities for you, the locking mechanism and divider in Product A are practical advantages. The support rod in Product B aids in ease of access but lacks the organizational flexibility of a divider.
Color Options
Aesthetics play a role in how the storage box blends with your outdoor decor. Product A is available in Grey, Black, Walnut, and Driftwood colors. This variety allows you to match different patio furniture styles. Product B is currently listed in Black and Grey. While both offer neutral tones, Product A provides more choices, including wood-like finishes like Walnut and Driftwood. These options may better complement natural outdoor settings. If you prefer a specific color to match your existing decor, the wider selection in Product A gives you more flexibility. Both options are designed to look tidy and functional on a patio or deck.
