Devoko 80 Gallon Waterproof Lockable Storage Bench Deck Box
This storage bench stands out for combining ample 80 gallons of waterproof storage with seating functionality, making it a versatile choice for outdoor spaces. Compared to the Keter Atlas 70-Gallon, it offers a larger capacity and a sturdy steel reinforcement, but it is heavier and may require more effort to move once assembled. Its lockable feature adds security for valuable outdoor items, and the bench design encourages social use, perfect for patios hosting gatherings. The main tradeoff is its weight, which could hinder relocation, and assembly may be time-consuming for some users. Overall, this model suits those who want both a practical storage solution and extra seating without sacrificing security.
Pros:- Large 80-gallon capacity keeps outdoor items organized
- Lockable for added security
- Provides extra seating for outdoor gatherings
- Sturdy steel reinforcement enhances durability
Cons:- Assembly may be required, which can be time-consuming
- Heavy weight makes relocation difficult
Best for: Families or outdoor hosts needing large-capacity storage combined with seating for gatherings
Not ideal for: Individuals seeking lightweight, easily movable storage solutions or those with limited space for bulky furniture
- Exterior Dimensions:52.8 in. L x 22.6 in. W x 32.3 in. H
- Interior Dimensions:48.4 in. L x 22.4 in. W x 16.9 in. H

Our verdict“This pick is ideal for those wanting a secure, multi-use outdoor storage bench with high capacity and seating comfort.”
Keter Atlas 70 Gallon Outdoor Storage Box for Patio and Pool Accessories
The Keter Atlas offers a sleek, modern design with 70 gallons of weather-resistant storage, making it an attractive yet functional choice. It compares favorably to the Devoko 80 Gallon Storage Bench for its mobility features—built-in wheels and handles—adding convenience for frequent reorganization or cleaning. However, its lockable lid does not come with a lock, which limits security, unlike the Devoko’s lockable features. Assembly is straightforward but may require some effort, especially when attaching the wheels and handles. This box makes the most sense for users who prioritize style, ease of movement, and weather resistance over maximum capacity or security, which could be a tradeoff for those storing valuables.
Pros:- Large 70-gallon capacity suitable for patio and pool accessories
- Weather-resistant resin construction
- Built-in wheels and handles for easy mobility
- Sleek, modern wood-look finish complements outdoor decor
Cons:- Locking mechanism does not include a lock, limiting security
- Assembly may require some effort despite being tool-free
Best for: Homeowners needing a stylish, weatherproof storage solution that’s easy to move around
Not ideal for: Those storing valuable or high-security items, since it lacks a lockable locking mechanism
- Capacity:70 gallons
- Material:Weather-resistant resin
- Design:Wood-look textured finish
- Features:Lockable lid, built-in wheels, side handles, tool-free assembly
Our verdict“Ideal for style-conscious users who need portable, weatherproof outdoor storage with decent capacity.”
LAUSAINT HOME 230 Gallon Resin Deck Box with Lockable Lid, Waterproof Outdoor Storage for Garden Tools and Patio Cushions
The LAUSAINT HOME 230-Gallon deck box excels in offering massive storage capacity, making it perfect for large outdoor spaces with extensive storage needs. Its weather-resistant high-density resin and reinforced structure withstand the elements, similar to the Drato 135-Gallon Deck Box, but with nearly double the capacity. Its fully assembled design cuts down setup time, yet it lacks an included lock, only featuring holes for locks, which could be a security concern. Its limited color options and potential heaviness when filled are tradeoffs for its enormous volume. This option makes the most sense for homeowners with large gardens or patios needing to store bulky items securely in a weatherproof container.
Pros:- Massive 230-gallon capacity for extensive storage needs
- Weather-resistant and durable construction
- Lockable lid enhances security (with a lock)
- Easy to assemble and move with handles
Cons:- No included lock, only holes for locks
- Heavy when filled, making relocation difficult
Best for: Large households or property owners needing high-capacity, weatherproof outdoor storage for bulky items
Not ideal for: Small spaces or users looking for lightweight, easily movable solutions, as this model is heavy when filled
- Capacity:230 gallons
- Material:High-density PP resin
- Color:Black
- Weather-resistant:Yes
- Assembly:Fully assembled in 15 minutes
Our verdict“Best suited for those with large outdoor storage needs who prioritize security and weather resistance over portability.”
DRATO 135 Gallon Waterproof Outdoor Deck Box with Wheels
The DRATO 135-Gallon deck box balances size and mobility well, making it suitable for storing cushions, tools, or outdoor gear. It compares favorably with the LAUSAINT HOME 230-Gallon in size but offers the advantage of wheels, providing easier relocation. Its lockable feature adds a layer of security, yet the assembly instructions could be clearer, and the weight when filled might challenge some users. Its ability to double as a bench or side table adds versatility, especially for smaller patios or decks where multifunctional furniture is desirable. This model suits those who want ample outdoor storage without sacrificing mobility or secondary use options, although it’s not the lightest when fully loaded.
Pros:- Ample 135-gallon storage capacity
- Weatherproof, durable resin construction
- Lockable for security
- Can serve as a bench or side table
Cons:- Assembly instructions could be clearer
- May be heavy when fully loaded
Best for: Outdoor enthusiasts seeking a sizable, lockable storage box with mobility and multifunctional use
Not ideal for: Users who prioritize ultra-lightweight or purely aesthetic solutions, since it can be heavy when filled
- Capacity:135 gallons
- Material:Resin
- Weight Capacity:350 pounds
- Features:Lockable, Waterproof, Wheels, Easy to assemble
Our verdict“A good choice for those needing sizable, lockable, and multifunctional outdoor storage with mobility features.”
Devoko 78 Gallon Waterproof Resin Deck Box
The Devoko 78-Gallon deck box offers a slightly smaller yet stylish option for outdoor storage, featuring a waterproof resin build with a chic rattan pattern. It compares favorably to the Keter Atlas 70-Gallon in capacity, providing ample space for cushions or small tools while adding aesthetic appeal. Its handles and hydraulic hinge make moving and opening convenient, and the lockable lid enhances security. However, its limited details on weight and dimensions mean users should consider if the weight might be heavy when filled. This model is best for those who want a combination of style, moderate capacity, and security in a more compact form, but it may not be suitable for extensive storage needs.
Pros:- 78-gallon capacity offers ample storage
- Weather-resistant resin with rattan pattern design
- Handles and hydraulic hinge for ease of use
- Lockable lid for security
Cons:- Limited details on weight and dimensions
- Potentially heavy when filled
Best for: Homeowners seeking a stylish, secure, and moderate-capacity outdoor storage box for cushions or small tools
Not ideal for: Users needing very large capacity or heavy-duty storage, as its size and features are more suited for lighter use
- Material:Waterproof resin
- Capacity:78 gallons
- Design:Rattan pattern
- Features:Handles, hydraulic hinge, lockable lid
Our verdict“Ideal for those needing a compact, stylish, and secure outdoor storage option with moderate capacity.”
Keter Kentwood 50 Gallon Outdoor Storage Box and Patio Side Table
The Keter Kentwood stands out for its compact size and multi-purpose design, making it perfect for small balconies or patios where space is limited. Its 50-gallon capacity is suitable for light outdoor storage but falls short compared to larger options like the Greesum 31-Gallon box or the EFU 150-Gallon model. The resin material is weather-resistant, and its quick, tool-free assembly makes setup effortless. However, the absence of an included lock and limited capacity mean it’s less suited for securing valuable items or for those with extensive storage needs. Compared with larger boxes like the Westwood or EFU, it prioritizes convenience and style over capacity and security. This pick makes the most sense for apartment dwellers or those needing a stylish, space-efficient solution for light outdoor storage and seating.
Pros:- Compact size ideal for small outdoor spaces
- Multifunctional as seating and storage
- Easy, tool-free assembly
Cons:- Limited capacity may be insufficient for larger storage needs
- No included lock for security
- Only suitable for small outdoor areas
Best for: Apartment owners or small-space dwellers needing a stylish, dual-purpose storage and seating option
Not ideal for: Homeowners with large outdoor storage needs or those requiring secure locking for valuable items
- Capacity:50 gallons
- Material:Weather-resistant resin
- Assembly:Tool-free, under 10 minutes
- Use:Storage and seating
Our verdict“Best suited for those needing a space-saving, multi-use outdoor storage solution with easy setup.”
Keter Westwood 150-Gallon Outdoor Storage Box for Patio and Pool Accessories
The Keter Westwood offers a substantial 150-gallon capacity, making it ideal for storing cushions, pool accessories, and garden tools. Its dual-purpose design as a bench with seating for two adds versatility, especially for larger patios or poolside areas. Compared to smaller models like the Kentwood, the Westwood prioritizes capacity, but it is significantly heavier and more difficult to move once filled. Its resin construction is durable and weather-resistant, although prolonged sun exposure may cause some fading over time. The automatic lift mechanism ensures easy access, but limited seating capacity may not suit households needing more than two seats. This product is best for homeowners seeking a large, weatherproof storage solution that also functions as outdoor seating without sacrificing style.
Pros:- Large 150-gallon capacity for extensive outdoor storage
- Dual-purpose as a bench and storage box
- Weather-resistant resin construction
- Easy to open with automatic lift mechanism
Cons:- Heavy and challenging to move when filled
- Limited seating for only two
- Potential fading with long-term sun exposure
Best for: Homeowners with sizable outdoor storage needs who want a dual-function bench and weatherproof durability
Not ideal for: Users with limited space or those needing lightweight, portable storage options
- Capacity:150 gallons
- Exterior Dimensions:61″ L x 28.34″ W x 25.19″ H
- Interior Dimensions:56″ L x 24.6″ W x 22.8″ H
- Material:Resin
Our verdict“Ideal for those needing ample, weatherproof outdoor storage combined with seating on a larger patio or poolside area.”
Quictent 120 Gallon Heavy Duty Resin Deck Box
The Quictent 120-Gallon Deck Box balances large capacity with sturdy, weather-resistant design, making it suitable for storing patio cushions, tools, or seasonal gear. Its heavy-duty resin construction provides waterproofing and UV resistance, comparable to the EFU model but with a focus on durability for long-term outdoor exposure. It features a lockable lid, but manual locking means security depends on users adding a padlock. Compared with the EFU, it offers similar capacity but emphasizes a more straightforward assembly process. While heavy once filled, its robust build and weatherproof features make it a reliable choice. This product is best for homeowners seeking a durable, lockable storage bench that’s easy to assemble and maintain for outdoor spaces that see frequent use.
Pros:- Large 120-gallon capacity for outdoor storage
- Durable, waterproof, UV-resistant resin
- Dual function as a bench and storage
- Easy to assemble
Cons:- Heavy when filled, difficult to move
- Requires manual locking with padlock for security
Best for: Homeowners needing durable, lockable outdoor storage for frequent outdoor use and seasonal items
Not ideal for: People requiring lightweight or highly portable options, or those needing a lock included in purchase
- Capacity:120 gallons
- Material:Resin
- Weather Resistance:Waterproof and UV resistant
- Warranty:2 years
Our verdict“Best for those seeking a tough, weatherproof, lockable outdoor storage solution that’s straightforward to set up.”
Greesum Outdoor Storage Box 31 Gallon with Lid for Patio Furniture, Garden Tools, Pool Supplies, Waterproof and UV Resistant, Lockable, Dark Black
The Greesum 31-Gallon Storage Box offers a practical solution for organizing tools, furniture, and pool supplies in a manageable size. Its eco-friendly resin is waterproof and UV resistant, ensuring durability over time. Compared to larger options like the EFU or Westwood, this model is more lightweight and easier to handle, making it suitable for users who need a moderate capacity without the bulk. Its lockable design adds security, although the padlock is not included, which might require an extra purchase. Assembly can be slightly effortful but is generally straightforward. This box works best for homeowners with moderate storage needs who want a secure, weatherproof container that also serves as an occasional seat or side table.
Pros:- Moderate 31-gallon capacity suitable for many outdoor items
- Waterproof and UV resistant for durability
- Multi-functional as a seat or side table
- Secure lockable design
Cons:- Padlock not included, adding extra cost
- Assembly may require some effort
Best for: Homeowners with moderate outdoor storage needs seeking a compact, lockable, weatherproof solution
Not ideal for: People with large storage requirements or those needing included locks for high-security storage
- Capacity:31 gallons
- Material:Eco-friendly resin
- Color:Dark Black
- Features:Lockable, waterproof, UV resistant
Our verdict“Great for users needing a compact, secure, and weatherproof outdoor storage option for moderate items.”
EFU Outdoor Storage Box Waterproof 150 Gal Resin Deck Box with Wheels
The EFU 150-Gallon Deck Box combines a large storage capacity with mobility, thanks to its built-in wheels and gas struts for effortless opening. Its waterproof and dust-proof design keeps outdoor gear protected, similar to the EFU model but with an emphasis on ease of access. The lockable lid enhances security, although users must manually lock it with a padlock, similar to the Quictent. Its scratch-resistant resin withstands long-term outdoor exposure, and the wheels make positioning easier—though full loads can make it heavy to move. This product is particularly well-suited to those requiring large capacity, easy access, and mobility for bulky outdoor storage, such as gardeners or pool owners.
Pros:- Spacious 150-gallon capacity
- Waterproof and dust-proof for long-term outdoor use
- Wheels and gas struts for easy access and mobility

- Capacity:150 gallons
- Material:Resin

- Features:Waterproof, dust-proof, lockable, wheels
Our verdict“Best for users who need a large, secure, and mobile outdoor storage solution with effortless access.”
Greesum 110 Gallon Outdoor Storage Box with Lockable Lid
This weatherproof storage box stands out for its balanced combination of capacity, durability, and multi-functionality. With 110 gallons of space, it surpasses smaller options like the Keter Kentwood 92-gallon model, offering ample room for garden tools, cushions, and toys. Its fade-resistant, wood-grain finish blends style with resilience, and hydraulic rods provide smooth, safe lid operation. Unlike the 50-gallon Keter Premium Everwood, this box offers significantly more storage, making it ideal for bigger outdoor setups. The main tradeoff is its weight when fully loaded, which can make repositioning cumbersome. Still, its multi-use design as a bench or side table adds practical value. This pick makes the most sense for those needing a spacious, durable, and versatile outdoor storage solution.
Pros:- Generous 110-gallon capacity for large outdoor items
- Weatherproof, fade-resistant material withstands harsh conditions
- Hydraulic rods ensure safe, easy lid operation

Our verdict“Ideal for users who prioritize capacity and multi-functionality in a weatherproof outdoor storage box.”
Keter Kentwood 92 Gallon Outdoor Storage Box for Patio and Pool Accessories
Compared with larger options like the Greesum 110-gallon model, the Keter Kentwood offers a solid 92 gallons that suits most patio storage needs without overwhelming space. Its resin construction is resistant to rust, fading, and weather, making it a reliable choice for outdoor use. The high weight capacity (573 lbs) doubles as extra seating, adding practical value for smaller gatherings. While its assembly can take longer than the Greesum due to fewer ergonomic features, it remains straightforward for most users. The main tradeoff is its limited capacity relative to larger boxes, making it less suitable for bulky items or extensive outdoor gear. This makes it a practical, budget-friendly choice for medium-sized outdoor storage needs.
Pros:- Resistant to rust, fading, and weather damage
- Provides extra seating with high weight capacity
- Secure lockable lid for outdoor security
- Easy to assemble and maintain
Cons:- Assembly can be time-consuming for some users

- Interior Dimensions:49.6 in. W x 20 in. D x 22.8 in. H
- Capacity:92 gallons
- Material:Resin

Our verdict“A reliable mid-sized option that balances capacity, durability, and seating for typical outdoor storage needs.”
160 Gallon Outdoor Storage Box Waterproof Lockable Deck Box, Black
This 160-gallon deck box offers a generous capacity while prioritizing weather resistance, setting it apart from the smaller 92-gallon Keter Kentwood. Its waterproof design with a durable resin body and wood-like texture ensures protection against rain, snow, and UV rays, making it suitable for year-round outdoor use. The lockable feature enhances security, especially compared to boxes that lack locks, and ergonomic handles facilitate repositioning despite its weight. While heavier when filled, its waterproof capabilities and elegant look make it suitable for stylish outdoor settings. The main tradeoff involves limited color options—only black—and weight considerations when fully loaded. It suits users needing robust, weatherproof storage with multi-purpose functionality in a stylish package.
Pros:- Waterproof and weather-resistant for all-season use
- Lockable lid for added security and privacy
- Multi-purpose as storage, bench, or side table

Our verdict“Best suited for users needing durable, weatherproof, and secure outdoor storage with a versatile design.”
Keter Premium Everwood 50 Gallon Outdoor Storage Box and Patio Side Table
This 50-gallon storage box is a compact, versatile choice for smaller outdoor spaces like balconies or patios. Its weather-resistant resin finish mimics wood, providing a stylish yet maintenance-free appearance. The tool-free assembly takes less than 10 minutes, making it accessible for quick setup. While it can’t handle large outdoor equipment like garden shovels or multiple cushions, its dual function as a storage and seating unit makes it perfect for light outdoor clutter. Compared with larger boxes like the Greesum 110-gallon, it’s more limited in capacity but excels in ease of use and aesthetics. Its main drawback is the lock feature, which requires additional hardware, and the capacity may be insufficient for bigger storage needs. This option is ideal for those with modest outdoor storage requirements.
Pros:- Weather-resistant, fade-free resin finish
- Multi-functional as storage and seating
- Quick, tool-free assembly
- Stylish wood-like appearance
Cons:- Limited capacity at 50 gallons

- Capacity:50 gallons
- Material:Weather-resistant resin
- Assembly:Tool-free, under 10 minutes
- Finish:Fade-free, Signature Collection
Our verdict“A highly practical choice for small outdoor spaces needing discreet, dual-purpose storage and seating.”
200 Gallon Large Outdoor Storage Box, Black
Compared with the 160-gallon waterproof box, this 200-gallon model offers the most space for storing patio cushions, gardening tools, and pool accessories. Its black, resin construction is UV-resistant and impact resistant, making it suitable for year-round outdoor environments. The waterproof, lockable lid provides security and protection against weather, similar to the 160-gallon option, but with even more capacity for larger or numerous items. Its stylish wood-texture finish complements outdoor decor, and the easy assembly process adds convenience. The main downside is that the lock does not come with a padlock, requiring buyers to purchase one separately, and the box can be quite heavy when filled. This model is best for those with extensive outdoor storage needs who want durability and style in a large package.
Pros:- Massive 200-gallon capacity for extensive outdoor storage
- Weatherproof, UV-resistant, impact-resistant construction
- Stylish wood texture complements outdoor decor
- Easy to assemble with secure, waterproof lid

How We Picked
Products were evaluated based on durability, weather resistance, security features, size options, ease of use, and overall build quality. We prioritized models with strong waterproofing, reliable locking systems, and user-friendly features. The ranking reflects a balance between capacity, value, and versatility, ensuring options suit different needs—from casual backyard storage to more secure applications. Cost was considered, but higher prices were justified by added security or larger capacity. This approach ensures that each selected product offers a meaningful advantage for its target user, whether for basic storage or more demanding outdoor security.Factors to Consider When Choosing Lockable Outdoor Storage Boxes
Choosing the right lockable outdoor storage box involves more than just size or price. To make a smart investment, consider factors that affect durability, security, usability, and compatibility with your outdoor space. Understanding these key points helps avoid common pitfalls, like underestimating capacity or selecting a box that isn’t weatherproof enough for your climate. Here are the main considerations to guide your decision:Size and Capacity
Determine how much storage space you need before purchasing. Larger boxes like the LAUSAINT HOME 230 Gallon model provide ample room for bulky items such as garden tools and furniture cushions, but they can be heavy and difficult to move once filled. Smaller options like the Greesum 31 Gallon are more manageable but suitable only for light or minimal storage. Remember, oversized boxes may also look out of place or be more vulnerable to wind or theft if not secured properly.
Weatherproofing and Waterproof Features
Since these boxes are meant for outdoor use, weatherproofing is non-negotiable. Materials like resin, polyethylene, or treated wood resist moisture and UV damage better than cheaper alternatives. Pay attention to seals around lids and doors—poor seals can lead to water ingress, damaging contents. Investing in a model with proven waterproof features extends the lifespan of your storage and keeps your belongings dry in rain or snow.
Security and Locking Mechanisms
Not all lockable storage boxes are equally secure. Some rely on simple latches or hasp systems that can be forced open, while others come with integrated locks or space for padlocks. Consider your security needs—if you keep valuables or want to prevent theft, opt for a box with a built-in lock or reinforced locking points. For less critical storage, a basic latch may suffice, but always check how the lock mechanism withstands tampering.
Design and Aesthetics
The appearance of your storage box can influence your outdoor decor. Some models, like the Keter Westwood or Everwood, mimic wood finishes for a natural look, blending seamlessly with gardens or patios. Others prioritize function over form, offering utilitarian designs suitable for behind sheds or in less visible areas. Choose a style that complements your outdoor space, but don’t sacrifice durability or security for aesthetics—these features often come with tradeoffs.
Ease of Use and Maintenance
Look for features that make access and maintenance straightforward. Gas shocks or hydraulic hinges can make opening lids easier, especially for heavier boxes. Some models include wheels for portability—ideal if you need to move your storage frequently. Maintenance-wise, resin and plastic models typically require less upkeep than wood, which may need sealing or staining over time. Consider how often you’ll access the box and whether you prefer a lightweight, portable option or a more permanent fixture.
Frequently Asked Questions
Can I use a lockable outdoor storage box in snowy climates?
Yes, many lockable outdoor storage boxes are designed to withstand snow and cold temperatures, especially those made from weather-resistant resin or polyethylene. Ensure the model you choose has proper seals and a sturdy lock mechanism to prevent water ingress and freeze-thaw damage. Regularly clearing snow from the lid and inspecting seals can help maintain the box’s integrity over winter.
Are lockable outdoor storage boxes theft-proof?
While no outdoor storage solution can be completely theft-proof, choosing a box with a robust locking system and reinforced construction can significantly increase security. Higher-end models with integrated locks and tamper-resistant features make forced entry more difficult. For high-value items, consider additional security measures like anchoring the box to the ground or installing surveillance.
How important is material quality in choosing an outdoor storage box?
Material quality directly impacts durability and weather resistance. High-quality resin, polyethylene, or treated wood resist moisture, UV damage, and pests better than cheaper alternatives. Investing in a well-made model often results in longer lifespan and fewer maintenance issues. Cheaper options may save money upfront but can deteriorate quickly, especially in harsh climates.
Can I customize or modify a lockable outdoor storage box?
Some models allow minor modifications, such as adding extra locks or shelves, but most are designed as complete units. Customization depends on the material—metal or wood may offer more options for modifications than resin or plastic. Always check manufacturer guidelines and warranty conditions before attempting alterations, as improper modifications can compromise security or weatherproofing.
What is the typical lifespan of a lockable outdoor storage box?
The lifespan varies based on material, quality, and climate conditions. Well-made resin or polyethylene boxes can last 10 years or longer with minimal maintenance, while cheaper models might need replacement within 3-5 years. Proper care, such as cleaning and sealing, extends the life and keeps the box functioning securely over time.
