Deck boxes are a great solution for storing furniture cushions, pool accessories, outdoor supplies and tools, and so much more. The best deck boxes are engineered to withstand the elements and are made of durable plastic, aluminum, or hardwood to suit your decor. Their capacities range from 19 to 230 gallons — so opt for one that’s available in the best size for your storage needs and how much space you have. No matter what material or style you choose, the ideal box is one that’s also easy to assemble. For this, I’ve consulted real customers and their hands-on experience putting it together.

When choosing a deck box, you’ll first want to decide on a material:

  • Resin and polyethylene are two commonly used plastics in the construction of deck boxes, and they make for great heavy-duty, no-maintenance options.
  • Aluminum is a durable, lightweight metal that naturally resists water corrosion. The same qualities that make it great for patio furniture make it a good choice for deck boxes, particularly if what you’re storing inside won’t be damaged by heat since aluminum can get hot under the sun.
  • For a more organic look, try a wooden deck box. Just keep in mind that it might not offer the same amount of weather-resistance and will require more care. If you do choose to go with a wooden deck box, an outdoor-friendly yet affordable hardwood like acacia is a good bet for durability. (Just make sure to oil it regularly to maintain its look and sturdiness.)

The best deck box for you will largely depend on what you need to store and the style you prefer, but you should also take into consideration any extra features it has. While any reliable deck box will withstand some rain, sun, and wind, certain models are designed to be water-tight, which makes them ideal for storing pillows and other soft items. Some deck boxes have extra-sturdy double-walled construction, and some even double as seating. Built-in handles can make it easier to move a deck box around if need be, while lockable lids add an extra sense of security.

Read on for the best deck boxes on Amazon to suit your storage needs and preferences.

1. The Overall Best Deck Box

Clocking more than 4,000 Amazon ratings and 4.6 stars overall, this Rubbermaid deck box is an all-around solid option. It offers double-wall polyethylene construction and stainless steel hardware that resists rust. The weather- and water-resistant seal protects what’s inside and keeps it dry. While it’s the heaviest option on this list, it features built-in handles that make it easier to lug around when you need to.

Other highlights include a lockable, UV-protected lid that won’t fade or peel. One reviewer also noted that assembly was “quick and easy” thanks to the detailed step-by-step instructions. Plus, the box can double as seating, too.

  • Exterior dimensions: 59.3 x 28.3 x 27.2 inches (length x width x height)
  • Interior capacity: 150 gallons
  • Weight: 53 pounds

Promising Amazon review: “Great storage box. We got it for our pool deck. The 150 gallon size is HUGE and holds everything. The box is very sturdy and well made. Took about 40 minutes to put together. Waterproof and should hold up great in the weather. You can even lock it. Very pleased and highly recommend.”

2. The Best Large Deck Box If You’re On A Budget

This double-wall deck box is made with a resin that’s constructed to look like wicker. According to the manufacturer, the box is weather-resistant, and reviewers agree: “Have had it on edge of my patio for six months getting rained on and some sun. All is good so far. It is still sturdy and waterproof.” Another reviewer added, “Interior stays completely dry through all kinds of rainfall.”

Although it’s not designed for use as a bench, the sides have recessed handles and the lid can be locked when not in use. According to the manufacturer — and reviewers — the deck box is easy to assemble with minimal tools, as long as you follow the instructions. One customer reported that it took just five minutes to put together.

  • Exterior dimensions: 43.5 x 22 x 21.8 inches (length x width x height)
  • Interior capacity: 73 gallons
  • Weight: 32 pounds

Promising Amazon review: “Quality affordable patio storage [...] Large capacity for a good price. Looks great too. We bought 3.”

3. The Best Aluminum Deck Box

This Dinoka deck box is constructed out of aluminum with a waterproof, light-resistant paint coating to help keep items inside dry. The manufacturer specifies that the single-walled box is strong enough to be used as outdoor seating for up to three adults. One reviewer confirmed, “This deck box is so durable that people can even sit on it for extra seating space.” It’s lockable on two sides to ensure your items will be safely stowed. The box doesn’t feature handles, but it is easy to put together, according to reviewers.

  • Exterior dimensions: 59.1 x 19.7 x 19.7 inches (length x width x height)
  • Interior capacity: 75 gallons
  • Weight: 35.9 pounds

Promising Amazon review: “[...] I love the waterproof storage, which is a big change from my old plastic box. It has rained and snowed on this box and the inside has stayed dry. As such, it is a perfect box for storing outdoor cushions and things that I need to stay dry.”

4. The Best Wooden Deck Box

Made of acacia wood, this beautiful deck box is finished with a protective teak oil coating and built to withstand the elements. It has a breathable, slotted-wall design to prevent odor build-up — but the slotted design also means it can get wet inside, making it ideal for storing items that don’t need to stay dry. One reviewer explained, “I wouldn't suggest storing anything that absolutely can't get wet in these, because there is a small amount of breathing room between the side slats. They are angled downward (away from the box), so it would take snow or some extreme rain, but moisture can definitely get in.”

Reviewers have attested that it’s easy to assemble, although it’s not lockable and lacks handles. According to the manufacturer, the box also doubles as a bench and can seat up to two adults.

  • Exterior dimensions: 47.5 x 17.5 x 17.5 inches (length x width x height)
  • Interior capacity: 47 gallons
  • Weight: 31 pounds

Promising Amazon review: “Beautiful wood and design, was easy to assemble, came well packaged, hinges hold the lid up securely, lid operates smoothly, good design. The slotted bottom allows rain water to exit the storage area.”

5. The Best Extra-Large Deck Box

With 230 gallons of storage space, Keter’s XXL deck box was designed with large items in mind. According to the manufacturer, the box’s weather- and rust-resistant resin material — which is designed to mimic the look of wood — requires no maintenance whatsoever.

Reviewers have noted that the design is watertight, with one fan describing, “I can't say enough nice things about this storage box. It’s been raining for the last few days but the cushions are dry.” Not only is it “super easy to assemble,” according to one user, but it’s also equipped with a lock and built-in handles for added convenience. The manufacturer does not specify if it can be used as seating.

  • Exterior dimensions: 58 x 32.8 x 34 inches (length x width x height)
  • Interior capacity: 230 gallons
  • Weight: 49 pounds

Promising Amazon review: “Really sturdy, nice, spacious box! We needed something that would fit all of our cushions, and this did just that. Looks nice, feels sturdy, so far happy with the purchase.”

6. The Best Small Deck Box

This compact Rubbermaid deck box offers double-walled resin construction and is small enough to double as an end table yet strong enough to be used as extra seating. The manufacturer doesn’t specify how watertight the deck box is, but one reviewer noted, “My six patio pillows fit perfectly and didn’t get wet in all the rain we’ve had...over 10” in four days!!!” Another attested that their mini box had “withstood a lot of severe storms/rains with no impact.” While there are no handles, it is lighter and smaller than the other deck boxes on this list, making it relatively easy to lift and move around.

Many reviewers have found assembly to be easy enough for this model, as long as you follow the instructions — but several have noted that one of the initial steps is to fill the base with sand. (Some reviewers claimed to have skipped this step without issue, but if you’re not filling the deck box with something heavy, it might be worth adding some sand to your cart to make sure it stays put!) However, this deck box isn’t lockable.

  • Exterior dimensions: 18 x 17 x 23 inches (length x width x height)
  • Interior capacity: 19 gallons
  • Weight: 12.4 pounds

Promising Amazon review: “It’s the perfect size for my apartments patio storage necessities, which includes garden tools, a few smaller pots, a coal hod and bag of lump charcoal. Was easy to assemble.”

7. The Best Outdoor Storage Bench

If you’d prefer a deck box that looks and functions as a bench, consider this one from Keter. While there are mixed reviews on whether this storage bench keeps everything inside it dry, it’s made with a weather-resistant resin that’s designed to look like wood but won’t rust, rot, or decay over time, according to the manufacturer. The design can hold up to two people at a time and it’s lockable. It’s easy to assemble, too — one customer wrote that it “took maybe 30 minutes” to set up.

  • Exterior dimensions: 24.1 x 52.2 x 35 inches (length x width x height)
  • Interior capacity: 60 gallons
  • Weight: 41.9 pounds

Promising Amazon review: “Wonderful storage bench. Placed on my outdoor patio. Will store pillows, grandchildren’s outdoor table games in. Also use as extra seating [...] Very pleased with this item and highly recommend.”
