More Details on Our Top Picks
Devoko 120 Gallon Resin Outdoor Storage Box Waterproof Large Deck Storage Bench Lockable
This Devoko model stands out for combining generous capacity with a dual-purpose design, serving as both a large storage unit and a sturdy bench. Its 120-gallon capacity surpasses many competitors like the Greesum 82-gallon box, making it ideal for sizable yard needs. The resin construction with a wood-like finish offers a balance of durability and aesthetic appeal, though it can be quite heavy when filled, complicating repositioning. Compared to the Keter Westwood, it provides more storage but may lack the same ease of handling when fully loaded. Its lockable lid and reinforced sides enhance security and stability, making it suitable for outdoor environments. However, limited color options could be a drawback for those seeking more customization. This pick is perfect for homeowners prioritizing large capacity and multifunctionality without sacrificing style.
Pros:- Large 120-gallon capacity for extensive outdoor storage
- Water-resistant resin with a wood-like finish for style and durability
- Dual-purpose as a bench and decorative piece
- Reinforced sides and hydraulic hinge for stability
Cons:- Heavy when filled, making repositioning difficult
- Limited color options restrict aesthetic flexibility
Best for: Homeowners who want a large, stylish storage solution that doubles as outdoor seating and are willing to handle a heavier unit.
Not ideal for: People needing a lightweight, easy-to-move option or seeking multiple color choices for aesthetic matching.
- Capacity:120 gallons
- Material:Resin
- Design:Wood-like grain
- Features:Waterproof, lockable, hydraulic hinge, reinforced sides
Our verdict“A versatile, high-capacity choice best suited for those who value style, durability, and multifunctionality in outdoor storage.”
Greesum Outdoor Storage Box 82 Gallon Waterproof and UV Resistant Storage Bin with Lockable Lid
The Greesum 82-gallon box offers a solid balance of capacity and weather resistance, making it a practical alternative to the larger Keter Westwood for smaller yards. Its UV and waterproof features provide durability against sun and rain, while the lockable lid adds security—comparable to the Keter but with a slightly smaller footprint. Assembly might require some effort, especially for those less experienced, and its black color limits aesthetic options. Compared to the Devoko 120-gallon model, it sacrifices some capacity but gains in ease of handling and affordability. Its ability to serve as a seat or table increases outdoor versatility, yet the limited color palette could be a drawback for style-conscious buyers. This makes it ideal for users seeking reliable, weatherproof storage without bulk or complexity.
Pros:- 82-gallon capacity for ample outdoor storage
- UV resistant and waterproof for extended outdoor use
- Can double as a seat or table for added utility
- Lockable lid for security
Cons:- Assembly may be somewhat challenging
- Limited color options restrict visual customization
Best for: Gardeners or patio owners needing a durable, secure storage box with multi-use functionality in a manageable size.
Not ideal for: Those requiring maximum capacity or a variety of colors for aesthetic purposes, or who prioritize minimal assembly effort.
- Capacity:82 gallons
- Material:Resin
- Weather Resistance:Waterproof, UV resistant
- Lockable:Yes
Our verdict“A dependable, weather-resistant storage solution with multi-use potential for medium-sized outdoor spaces.”
Keter Westwood 150 Gallon Outdoor Storage Box for Patio and Pool Accessories, Brown
The Keter Westwood offers an impressive 150-gallon capacity, making it one of the largest options in this lineup. Its weather-resistant resin construction is designed to withstand outdoor elements, and the dual-purpose design includes a comfortable bench for outdoor gatherings. Its easy-lift lid and lockable feature add convenience and security, similar to the Greesum but with a larger storage volume. The weight once filled can be significant, and assembly may take some time, which could be a hurdle for those seeking quick setup. Compared to the Devoko, it provides less aesthetic variety but more seating comfort and security features. Its limited color options are a minor drawback for color-matching needs. This model suits those who prioritize large capacity combined with seating and security for outdoor spaces.
Pros:- Large 150-gallon capacity for extensive storage
- Weather-resistant and durable resin construction
- Dual-purpose as seating and storage
- Lockable lid for security
Cons:- Heavy when filled, less portable
- Assembly can be time-consuming
Best for: Large families or hosts who need substantial storage combined with outdoor seating and security features.
Not ideal for: Individuals seeking lightweight or highly portable options, or those preferring multiple color choices.
- Capacity:150 gallons
- Material:Resin
- Dimensions:61″ L x 28.34″ W x 25.19″ H
- Weight:Depends on filled weight
Our verdict“An excellent choice for those needing maximum storage capacity paired with outdoor seating and security.”
Greesum 110 Gallon Outdoor Storage Box with Lockable Lid, Dark Black
This Greesum 110-gallon model balances substantial capacity with a more manageable size, making it suitable for smaller patios. Its resin construction offers excellent weatherproof and UV-resistant qualities, comparable to the Greesum 82-gallon, but with a slightly larger volume. The reinforced lid doubles as a sturdy bench or side table, similar to the Devoko 120-gallon but in a more compact form. Assembly is straightforward if instructions are carefully followed, and the lockable latch enhances security. Its dark black color might not suit all aesthetic preferences, but it’s practical for hiding dirt and wear. Compared to the larger Devoko, it offers easier handling but less total capacity. This box is ideal for users needing a durable, secure storage solution without the bulk of larger models.
Pros:- 110-gallon capacity for ample outdoor storage
- Weatherproof and UV resistant for durability
- Can double as a bench or side table
- Easy to assemble without tools
Cons:- Color may vary slightly due to lighting conditions
- Limited aesthetic variety
Best for: Small to medium outdoor spaces needing weatherproof, lockable storage with a compact footprint.
Not ideal for: Users with extensive storage needs or those who prefer multiple color options for matching outdoor decor.
- Capacity:110 gallons
- Material:Resin
- Color:Dark Black
- Product Size:48″ L x 26.8″ W x 22.4″ H
Our verdict“A sturdy, weatherproof storage box ideal for medium-sized outdoor areas seeking security and convenience.”
320 Gallon Outdoor Storage Box Waterproof Patio Organizer Black
This 320-gallon storage box stands out for its enormous capacity, making it suitable for large outdoor equipment, cushions, and tools. Its heavy-duty resin construction offers exceptional weatherproofing and UV resistance, supporting over 1,000 pounds, ideal for storing bulky items. Compared with the smaller Greesum options, this model prioritizes capacity over portability, being quite heavy when fully loaded and requiring assistance for movement. Its lockable design adds security, though it doesn’t include locks, which could be a concern for some users. Assembly is straightforward but may be time-consuming given its size. It’s perfect for large families or commercial spaces needing secure, weatherproof storage that can handle substantial weights, but less so for those with limited space or needing frequent repositioning.
Pros:- Massive 320-gallon capacity for extensive storage
- Heavy-duty resin with UV resistance for all-weather durability
- Supports up to 1,000 lbs for heavy items
- Easy to assemble without tools
Cons:- No locks included despite lockable design

Our verdict“The top choice for large outdoor storage that demands maximum capacity and weatherproof security, suitable for substantial outdoor equipment.”
Keter City 30 Gallon Resin Outdoor Storage Box and Patio Side Table, Brown
This 30-gallon resin box stands out for its dual functionality as both a storage unit and a side table, making it ideal for smaller outdoor spaces where versatility matters. Compared with larger options like the DRATO 55 Gallon Storage Box, it offers less capacity but is easier to fit into tight spots. Its wood-look texture adds aesthetic charm, although it may fade over time in direct sunlight, unlike the UV-resistant resin of the Devoko 30 Gallon Resin Deck Box. Assembly is tool-free, which is perfect for quick setup, but the limited internal space means it’s best for small accessories rather than bulky items. This pick makes sense for users who need a stylish, space-efficient solution that doubles as furniture, accepting some aesthetic compromise over larger, more durable boxes.
Pros:- Dual-purpose design as storage and side table
- Easy to assemble without tools
- Attractive wood-look resin finish
- Weatherproof and durable for outdoor use
Cons:- Limited storage capacity for larger items
- Potential for fading in prolonged sunlight
Best for: Gardeners or patio owners with limited space seeking a multi-functional side table and storage solution
Not ideal for: Homeowners with large outdoor storage needs or bulky equipment, since capacity and durability are limited
- Dimensions:22.75 in. L x 17.3 in. W x 21.7 in. H
- Interior Dimensions:22.71 in. L x 16.3 in. W x 20.3 in. H
- Capacity:30 gallons
- Material:Weather-resistant resin
- Color:Brown
Our verdict“This product suits those needing a compact, stylish outdoor table with moderate storage capacity.”
Devoko 30 Gallon Resin Deck Box Waterproof Outdoor Storage for Patio Furniture and Garden Tools
Compared to the Keter City model, the Devoko 30 Gallon Deck Box offers a higher UV resistance and a more modern, simple design that appeals to those prioritizing durability and function. Its lightweight build (just 8.8 pounds) makes it easy to move around, and it doubles as a sturdy extra seat supporting up to 220 pounds—great for small patios or decks where space is at a premium. The lockable lid adds some security, but the internal height may restrict larger or taller items, making it less suitable for bulky equipment. While the basic design might not satisfy buyers looking for decorative appeal, it’s an excellent choice for users who want straightforward, weatherproof storage and seating at an affordable price.
Pros:- Lightweight and highly portable
- Can serve as a sturdy extra seat
- Waterproof and UV resistant for outdoor durability
- Simple, quick assembly process
Cons:- Limited internal height restricts larger items
- Basic design may not appeal to aesthetic-focused buyers
Best for: Homeowners seeking a lightweight, waterproof storage solution that doubles as seating for small outdoor spaces

- Capacity:30 gallons
- Dimensions:22 x 16 x 20 inches
- Material:High density resin
- Weight:8.8 pounds
- Color:Black
- Additional features:Waterproof, UV resistant, lockable lid, extra seat
Our verdict“Ideal for users who want a compact, functional storage and seating option without fuss or bulk.”
DRATO 55 Gallon Waterproof Outdoor Storage Box, Lockable Resin Deck Box, Weatherproof Patio Furniture Storage, UV-Resistant, Black
Compared with the Devoko 30 Gallon, the DRATO 55 Gallon provides nearly double the storage, making it suitable for larger outdoor equipment, cushions, or pool supplies. Its sturdy resin construction and UV resistance promise durability over time, though the larger size and capacity mean it’s less suited for tight spaces. Its lockable design offers added security, unlike the Outdoor Deck Storage Box, which lacks a lock, making it a better choice for valuables. The weight capacity of 300 pounds allows it to double as a bench, but the assembly process could require some effort, especially for securing the lid properly. This makes it best for users needing significant storage combined with a durable, lockable outdoor bench.
Pros:- Spacious 55-gallon capacity for large items
- Weatherproof and UV resistant
- Lockable for added security
- Supports up to 300 pounds as a bench
Cons:- Limited color options
- Assembly may be somewhat labor-intensive
Best for: Homeowners with substantial outdoor storage needs who also want security and seating functionality
Not ideal for: Small patios or users seeking lightweight, easy-to-move options, due to its larger size and weight
- Capacity:55 gallons
- Material:Resin
- Color:Black
- Weight Capacity:300 lbs
- Weatherproof:Yes
- Lockable:Yes
Our verdict“This box fits best for those needing ample, secure outdoor storage with the bonus of durable seating.”
Outdoor Deck Storage Box, 50 Gallon Waterproof Resin Lockable Lid, Black
Compared with the Devoko and DRATO models, this 50-gallon outdoor storage box offers a sleek, modern appearance with a lockable lid that enhances security for outdoor essentials. Its UV-resistant resin and weatherproof design make it suitable for prolonged outdoor exposure, while its ability to support up to 500 pounds as a bench provides a significant seating advantage. However, the lock isn’t included, which could be inconvenient for securing valuables, and the color options are limited. Its easy assembly with handles makes it user-friendly, but the capacity may be insufficient for larger equipment, especially if you need to store bulky gear. This pick is best for users who prioritize security and a modern look without sacrificing function.
Pros:- Weatherproof, UV-resistant resin for outdoor durability
- Supports up to 500 lbs as a bench
- Lockable lid enhances security
- Easy, handle-assisted assembly
Cons:- Lock not included, requiring additional purchase

- Weather Resistance:UV-Resistant, Waterproof
Our verdict“This model suits users seeking a secure, stylish outdoor storage bench with a modern look and good capacity.”
35 Gallon Outdoor Deck Box Lockable Waterproof Storage Container for Garden Tools and Cushions
In comparison to larger options like the Greesum 82 Gallon, this 35-gallon deck box strikes a balance for users who need a sturdy, lockable, weather-resistant container without overwhelming space. Its modern design, made from a blend of iron, polypropylene, and wood, offers a stylish aesthetic that can blend into contemporary outdoor spaces. The interlocking panels allow for quick, tool-free assembly, but the capacity may limit its usefulness for bulkier items or extensive outdoor gear. Since the lock isn’t included, securing valuables requires an additional padlock.

Pros:- Modern, stylish design
- Weatherproof and UV resistant
- Easy, tool-free assembly with interlocking panels

This 150-gallon resin deck box stands out for its multi-functionality and weatherproof durability, making it ideal for those who want a single solution for storage, seating, and side table use. Compared with the Lifetime 60012, it offers a more versatile design but lacks a lock, which could be a concern for security. Its heavy weight, especially when filled, makes it less ideal for frequent repositioning, yet its easy snap-on assembly simplifies setup.

Lifetime 60012 Extra Large Deck Box, 130 Gallon, Desert Sand/Brown
The Lifetime 60012 offers a generous 130-gallon capacity with a stylish two-tone design, making it suitable for those who need ample outdoor storage without sacrificing aesthetics. Compared with the Devoko 100 Gallon, it provides a larger capacity but is significantly heavier and bulkier to move. Its HDPE plastic construction ensures durability and weather resistance, while the spring-hinged lid simplifies access. However, its size requires a dedicated space and may be less practical for smaller patios or decks. Its limited color options and weight make frequent repositioning a challenge, though its lockable lid adds security.

TARKARI 320 Gallon Lockable Resin Deck Box, Waterproof & UV-Resistant Outdoor Storage
The TARKARI 320 Gallon deck box offers a massive capacity, making it perfect for households with extensive outdoor gear or pool accessories. Its lockable, waterproof, and UV-resistant design compares favorably to smaller options like the East Oak 60 Gallon, which is better suited to light, infrequent storage needs. Its handles facilitate transport, but it’s quite heavy, limiting mobility once filled. The all-black aesthetic is sleek, though the lack of color choices could be a drawback for style-conscious buyers.

The EAST OAK 60 Gallon offers a compact, lockable, waterproof solution with a built-in bench supporting up to 660 lbs, making it suitable for smaller outdoor spaces. Unlike larger options such as the Devoko 100 Gallon, it limits storage capacity but excels in providing seating alongside moderate storage. Its easy snap-together assembly takes about 15 minutes, which is a plus for those who want quick setup. Its limited color options and size may not accommodate larger gear, and it requires a padlock for security, as it doesn’t come with one. Its UV resistance and weatherproof features are reliable for outdoor environments.

Devoko 100 Gallon Waterproof Resin Deck Box
The Devoko 100 Gallon combines a sleek rattan exterior with weather-resistant resin, making it a stylish yet functional outdoor storage option. It closely matches the capacity of the East Oak 60 Gallon but offers more interior space for patio furniture, cushions, and tools. Compared with larger options like the TARKARI 320 Gallon, it’s more manageable and easier to place in smaller yards or balconies.

How We Picked
To evaluate the best waterproof outdoor storage boxes, I focused on key factors such as weather resistance, durability, capacity, ease of use, and security features. Each product was assessed based on material quality, lockability, UV resistance, and overall build integrity. I also considered user feedback and versatility—whether the box could serve multiple purposes or fit into various outdoor settings. The ranking reflects a balance between value and premium features, aiming to recommend options suitable for different needs and budgets.Factors to Consider When Choosing Waterproof Outdoor Storage Boxes
Choosing the right waterproof outdoor storage box involves considering several important factors that impact both functionality and longevity. Beyond just storage capacity, you should think about materials, ease of access, security, and weatherproofing features. Understanding these elements helps you avoid common mistakes, like opting for a box that isn’t UV resistant or one that’s too small for your needs. A well-chosen storage box not only protects your items but also complements your outdoor space.Material and Weather Resistance
Durability against the elements is paramount. Resin and polypropylene are popular because they resist UV rays, moisture, and temperature fluctuations better than wood or metal, which can rust or rot over time. Look for boxes with UV-resistant coatings or materials to prevent cracking and fading. Keep in mind that cheaper plastics may degrade faster, so investing in higher-quality resin can pay off in the long run.
Size and Capacity
Match the box size to your storage needs. Larger boxes, like the 150-gallon models, are great for bulky items such as furniture cushions or pool accessories but can be cumbersome to move. Smaller options are easier to handle but may require multiple units for different items. Consider how much space you have available and what you plan to store to find a balance between capacity and practicality.
Security Features
Lockable lids provide peace of mind, especially if you leave your outdoor storage unattended or in a shared space. Not all storage boxes come with locks, so check whether a model includes a lock or if you need to purchase one separately. Remember that a secure lid helps prevent theft and keeps animals out, but it can sometimes make access less convenient if you need frequent, quick access.
Ease of Use and Accessibility
Consider how easily you can open and close the storage box. Features like gas struts or hydraulic hinges make lifting heavy lids easier, especially for larger models. Also, think about the placement—if you plan to place the box against a wall or under a deck, ensure the design allows for easy access from your preferred angle. Smooth, user-friendly lids save time and effort in daily use.
Design and Aesthetics
Since outdoor storage boxes are visible elements of your yard, select a style that complements your space. Many models now mimic wood textures or come in neutral colors that blend seamlessly with outdoor décor. A stylish design can upgrade the look of your patio while providing practical storage. However, prioritize function over appearance if your main concern is protection from the elements.
Frequently Asked Questions
Will a waterproof outdoor storage box keep my items completely dry in heavy rain?
While most waterproof outdoor storage boxes are designed to resist rain and moisture, no container is entirely airtight or completely waterproof under extreme conditions. Look for models with sealed or gasketed lids, which significantly reduce the chance of water ingress. Proper placement—such as on a raised platform—also helps protect contents from flooding or standing water. Regular maintenance and inspection can further ensure your stored items stay dry over time.
Are lockable storage boxes secure enough to prevent theft?
Lockable outdoor storage boxes provide a good level of security, especially when equipped with sturdy locks or padlocks. However, no lock is completely theft-proof, especially against determined intruders. For high-value items, consider additional security measures like anchoring the box to the ground or placing it within a secured area. The best lockable models combine weatherproofing with robust locking mechanisms for peace of mind.
Can I leave my storage box outside year-round without damage?
Yes, if you select a model made from UV-resistant, weatherproof materials like high-quality resin or polypropylene. Proper maintenance, such as cleaning and checking seals periodically, can extend the lifespan of your storage box. Avoid placing it directly on soil or uneven surfaces to prevent moisture buildup underneath. A well-made, UV-resistant box will resist cracking, fading, and degradation through multiple seasons.
What’s the best size for storing garden tools and cushions?
The ideal size depends on your storage needs, but generally, a capacity of around 50-150 gallons covers most garden tools and cushions comfortably. Larger boxes provide more room and reduce clutter, but they also tend to be heavier and less portable. Smaller options, such as 30-50 gallons, are easier to move and handle but might require multiple units. Think about the size of your typical items and available space before choosing.
Are there styles that look good in a modern outdoor setting?
Yes, many manufacturers now offer sleek, minimalist designs with neutral colors like grey, black, or beige that fit seamlessly into modern outdoor aesthetics. Resin or resin-wood composite options often feature clean lines and smooth finishes, making them both functional and visually appealing. When style matters, prioritize models with simple, contemporary designs that complement your outdoor décor while still providing the necessary weather protection.
