More Details on Our Top Picks
RTS Home Accents 55-Gallon Eco Rain Barrel with Removable Lid, Flat Back, Made with Recycled Plastic, Stand Included, Black
This 55-gallon rain barrel stands out for its environmentally friendly design, offering a larger capacity than many 50-gallon options like the FCMP Outdoor Raincatcher 4000. Its use of 100% recycled plastic appeals to eco-minded buyers seeking sustainable solutions. The flat back allows it to nestle tightly against walls or fences, saving space, and the included stand makes setup straightforward. Compared to smaller or non-recycled options, this model balances capacity and eco-credentials effectively. The main tradeoff is its limited size—55 gallons might fall short for larger gardens—and the plastic spigot could need replacement over time, especially in harsh weather. Still, this pick makes the most sense for those prioritizing sustainability and space efficiency in small to medium gardens.
Pros:- Eco-friendly design reduces environmental impact
- Flat back fits snugly against walls or fences
- Includes a sturdy stand for easy access
Cons:- Limited to 55 gallons capacity can be restrictive for larger gardens
- Plastic spigot may need replacement over time
Best for: Eco-conscious homeowners with medium-sized gardens needing reliable, space-saving rainwater collection.
Not ideal for: Large properties requiring extensive water storage, as 55 gallons may be insufficient for high-demand watering systems.
- Capacity:55 gallons
- Material:Recycled plastic
- Color:Black
- Stand Included:Yes
- Removable Lid:Yes
- Shape:Flat back
Our verdict“This rain barrel is ideal for eco-minded gardeners seeking a space-efficient, sustainable solution for moderate water needs.”
RTS Home Accents 50-Gallon Rain Barrel with Link Kit (2 Pack)
This 2-pack set offers a substantial 100 gallons combined capacity, making it a prime choice for homeowners who want to scale their rainwater harvesting. Each barrel, made from durable UV-resistant polyethylene, features a flat back for space-efficient placement, and the included link kit simplifies connecting multiple units for expanded storage. Compared with single barrels like the FCMP Outdoor Raincatcher 4000, this set provides more total capacity and convenience for larger gardens or multiple watering zones. A notable tradeoff is that the barrels ship separately, which may require multiple deliveries, and the stand is sold separately, adding to the cost. This product suits buyers seeking a straightforward, expandable system capable of handling extensive outdoor watering needs.
Pros:- Includes two large-capacity rain barrels for extensive water collection
- Flat back design maximizes space efficiency
- UV-resistant construction ensures durability outdoors
- Link kit simplifies expansion
Cons:- Ships in multiple packages, potentially requiring extra delivery coordination
- Optional stand must be purchased separately
Best for: Homeowners with large gardens or multiple planting areas needing scalable rainwater storage.
Not ideal for: Small yards or those with limited space, as the two barrels require more setup and space than single units.
- Capacity:50 gallons each
- Number of barrels:2
- Material:UV-resistant polyethylene
- Includes:Link kit, brass spigots, overflow valve, screens, hose barbs
- Made in:USA
- Shape:Flat back
Our verdict“This set is best for users planning to expand their rainwater system across a large outdoor area or multiple zones.”
FCMP Outdoor Raincatcher 4000 Rain Barrel, 50 Gallon, Brown
The Raincatcher 4000 offers a straightforward 50-gallon capacity, comparable to other single barrels but at a generally lower price point. Its flat-back design allows it to sit flush against the wall, maximizing space, and multiple units can be connected for greater storage—though it requires buying additional accessories separately. Compared with the RTS link kit options, this model may lack some of the included components, like overflow valves or screens, which means extra purchases. The main drawback is that it does not come with connectors or accessories, and its brown color might not blend as seamlessly into all garden aesthetics. It makes sense for buyers seeking an affordable, expandable system but willing to handle some assembly and additional purchases.
Pros:- Affordable price point for basic water collection
- Flat-back design fits against walls easily
- Expandable by connecting multiple units
Cons:- Requires separate purchase of connectors and accessories
- No included overflow or screens, adding to setup effort
Best for: Budget-conscious homeowners looking to start or expand their rainwater system gradually.
Not ideal for: Those who want a fully integrated package with accessories included or a more premium aesthetic.
- Capacity:50 gallons
- Color:Brown
- Material:Polyethylene
- Design:Flat-Back
- Expandable:Yes
- Includes:None, accessories sold separately
Our verdict“This rain barrel suits budget-minded buyers who want an expandable, space-efficient solution without extra frills.”
RTS Home Accents 50-Gallon Rain Barrel with Link Kit, Flat Back, 2 Pack
This 2-pack of 50-gallon barrels offers a balanced combination of capacity and space efficiency, with the added benefit of a link kit for easy expansion. Made from UV-resistant polyethylene, each unit features a flat back to minimize footprint and includes a built-in overflow valve for safety. Compared with the single-unit FCMP Raincatcher, this set provides more total storage and simplifies setup for larger gardens. However, it ships separately, which may complicate delivery, and the optional stand is sold separately, adding to the overall cost. It’s an excellent choice for those who want to quickly assemble a larger system with minimal spatial impact, provided they are comfortable with some assembly and additional purchases.
Pros:- Two large-capacity barrels for increased water storage
- Flat back design conserves space
- Includes link kit for seamless expansion
- Made in the USA for quality assurance
Cons:- Ships separately, requiring multiple deliveries
- Optional stand must be purchased separately

- Material:UV-resistant polyethylene
- Includes:Link kit, brass spigots, overflow valve, screens, hose barbs
- Made in:USA

Its flat-back profile allows it to sit flush against a wall, and it includes accessories such as a debris screen, garden hose, and water valves, making it a convenient all-in-one option. Compared to the linked kit options like RTS’s sets, this barrel emphasizes ready-to-use features but lacks the ability to connect multiple units without additional purchase. Its black color helps it blend into various garden settings, but the weight when filled can be cumbersome during installation. It’s ideal for users who want a reliable, large-capacity barrel with accessories ready for immediate use but are less focused on expansion or modularity.

The inclusion of a link kit and sturdy stands simplifies expansion and setup, which is a significant advantage for those building a larger system.

Its design is comparable to the FCMP Raincatcher 4000 but with a more traditional look and a built-in overflow valve, which enhances water management. The inclusion of comprehensive accessories, including brass spigots and a link kit, makes setup straightforward—though the optional stand must be purchased separately, adding to the overall cost.

Its flat-back design allows it to sit flush against a wall, and side spigots facilitate easy connection of multiple units for increased storage.

Factors to Consider When Choosing Large Rain Barrel System With Linking Kit
When choosing a large rain barrel system with a linking kit, several factors can influence your decision. Capacity is paramount if you’re collecting rainwater for extensive use, but larger units also tend to be heavier and more challenging to handle. Ease of linking and expanding your system depends on the design of the kit and compatibility between units. Materials matter for durability and environmental impact, with recycled plastics offering eco benefits at potentially lower costs. It’s also worth considering the included accessories like stands, spigots, and overflow options, which can affect overall value. Lastly, think about your space, budget, and whether you’re aiming for a simple setup or a scalable system for future expansion.Capacity and Scalability
Choosing the right capacity involves balancing your water needs with your ability to handle larger, heavier units. Larger barrels, such as 50 or 55 gallons, reduce the frequency of emptying but can be cumbersome to install and move. If you plan to expand your system over time, selecting models with compatible linking kits is essential. These kits allow you to connect multiple barrels easily, creating a more extensive rainwater harvesting network without significant additional effort or cost. Always verify that the linking components are durable and designed for seamless integration.Material Durability and Environmental Impact
Most large rain barrels are made from plastic, with recycled options gaining popularity for eco-conscious buyers. Recycled plastics tend to be more affordable and environmentally friendly, but they may degrade faster under prolonged sun exposure. Premium materials like UV-stabilized plastics or polyresins offer better longevity. Consider how the material will withstand your climate—UV resistance, impact strength, and chemical stability all matter. Investing in a more durable material can save money and hassle over the long term, especially if you live in a sunny or harsh environment.Linking Kit Compatibility and Ease of Expansion
A key factor in large systems is how easily you can connect multiple barrels. Some kits are designed for specific models, while others are universal. Look for linking kits that are straightforward to install, with clear instructions and secure connections. Compatibility issues can lead to leaks or unstable setups, so verifying the system’s flexibility before purchase is wise. Keep in mind that some models include built-in link kits, while others require you to buy accessories separately, which could add to your overall cost and complexity.Installation Space and Setup
Assess your available space carefully before choosing a large rain barrel system. Consider the weight of filled units and whether you have enough room for installation and future expansion. Flat-back models are advantageous for fitting against walls or fences, saving space. If mobility is important, lightweight options with easy-to-handle features are preferable. Proper placement also involves considering overflow management and accessibility for maintenance, so plan for a location that combines convenience with optimal water collection.Cost and Overall Value
While larger, more durable systems tend to cost more upfront, they often offer better long-term value through increased lifespan and expansion options. Multi-pack deals or kits that include linking accessories can provide significant savings. Beware of very low-cost options that may compromise on quality or durability, leading to higher replacement or repair costs later. Consider your budget in conjunction with your needs—spending a bit more initially can result in a more reliable, scalable system that grows with your water harvesting goals.Frequently Asked Questions
Can I connect different brands of rain barrels with the linking kit?
Connecting different brands of rain barrels with a linking kit is possible but not always guaranteed to be seamless. Compatibility depends on the size and type of the connection fittings. Some manufacturers design universal fittings, making it easier to mix and match units, while others use proprietary connectors. To avoid leaks or instability, it’s best to choose a system with standardized fittings or verify compatibility before purchasing. If mixing brands, consider purchasing universal linking accessories designed for multiple connection types to ensure a secure fit.
How much maintenance is required for a large rain barrel system?
Maintenance for large rain barrel systems primarily involves cleaning out debris, checking for leaks, and ensuring the overflow system functions properly. Regularly inspecting the inlet screens and filters helps prevent clogging and mosquito breeding. Cleaning the inside of the barrels annually can extend their lifespan and maintain water quality. If your system includes a linking kit, inspect fittings periodically for tightness and leaks. Overall, routine upkeep is straightforward but essential for long-term performance and water safety.
Are larger rain barrels more prone to leaks or damage?
Larger rain barrels can be more susceptible to stress-related damage if not properly supported or installed. The increased weight when filled makes sturdy mounting and placement critical. Poor-quality materials or improper installation can lead to cracks or leaks over time. Choosing a well-made, UV-stabilized plastic system reduces the risk of damage. Ensuring your setup includes proper stands or wall mounts can also prevent undue stress and prolong the system’s lifespan.
What should I know about overflow management in large rain barrel systems?
Overflow management is vital for preventing water from spilling onto foundations or walkways. Most large systems include overflow outlets or divertors, but their placement and capacity vary. Properly designed systems allow excess water to be directed safely away from your home or garden. When linking multiple units, ensure the overflow from one barrel can flow into the next or into a drainage area. Planning for overflow reduces the risk of water damage and keeps your installation tidy and functional.
Is it worth investing in a premium large rain barrel system?
Investing in a premium system often means better materials, more reliable linking components, and longer lifespan, which can justify the higher cost. For those with extensive water needs or a desire for a scalable setup, premium options provide peace of mind and fewer maintenance worries. However, if your needs are modest or you’re on a tight budget, more affordable models with good basic features can still deliver effective rainwater collection. The key is matching the system’s quality and capacity to your specific use case.
Conclusion
For most buyers, the RTS Home Accents 55-Gallon Eco Rain Barrel offers a reliable, well-rounded choice as the best overall. Those seeking maximum capacity and expandability should consider the FCMP Outdoor Raincatcher 4000, which combines size and durability for serious collectors. Budget-conscious shoppers will find value in multi-pack deals like the RTS Home Accents 50-Gallon Rain Barrel with Link Kit (2 Pack). Beginners or those with limited space might prefer flat-back models or smaller systems, while long-term collectors should look at premium options with reinforced materials. Matching your system to your specific water needs, space, and budget makes all the difference in choosing the right large rain barrel with linking kit.
