Best Rainwater Harvesting Storage Tanks for Home and Garden Use
The best rainwater harvesting storage tank depends on how much water you need, where it will sit, and whether portability or permanent placement matters most. The VEVOR 100-gallon tank is best for higher-capacity storage, while the Step2 60-gallon barrel adds an elevated design and mesh screen. For compact placement, consider the RTS 55-gallon flat-back barrel; the FCMP 50-gallon model suits expandable setups, and the Laspeiraux 53-gallon tank folds for storage.
| Product | Capacity | Best suited for |
|---|---|---|
| VEVOR Collapsible Rain Barrel | 100 gallons | Higher-volume collection |
| Step2 Lakewood Rain Barrel | 60 gallons | Elevated access and screened collection |
| RTS Premium Eco Rain Barrel | 55 gallons | Recycled materials and tight spaces |
| FCMP Outdoor Raincatcher 4000 | 50 gallons | Expandable barrel storage |
| Laspeiraux Collapsible Rain Barrel | 53 gallons | Portable, foldable storage |
VEVOR 100-Gallon Collapsible Rain Barrel
Best for: Households that want more storage in one portable tank. At 100 gallons, this model holds more than the other listed barrels, making it a practical choice for larger gardens or households that want to collect more runoff between uses.
Its body uses 1000D waterproof PVC, and the listed features include UV resistance, a spigot, an overflow kit, seven support rods, and a lotus-style base. Choose this model if a collapsible format and comparatively high capacity are priorities.
Limitation: This is a flexible PVC tank rather than a rigid barrel, and its support rods and base are part of its stability system. Check the setup requirements and available space before choosing it.
Step2 Lakewood 60-Gallon Rain Barrel
Best for: Gardeners who want a rigid 60-gallon container with an elevated design. The increased height is intended to make filling a watering can easier and improve water pressure at the outlet.
The barrel includes a stainless steel mesh screen to filter fine particulate, a 3/4-inch brass spigot, and the option to link multiple barrels for more storage and overflow management. It is a good fit when easy access to the spigot and a screened inlet are important considerations.
Limitation: Its 60-gallon capacity is below the VEVOR’s 100 gallons. Measure the intended location and consider whether an elevated barrel fits your space and setup.
RTS Premium 55-Gallon Eco Rain Barrel
Best for: Buyers who prefer a rigid barrel made from recycled plastic and need a design that can sit close to a wall or fence. Its flat back is intended to fit snugly against those surfaces, which can help when choosing a location near a downspout.
The 55-gallon capacity is suitable for collecting water for outdoor plants, lawns, and gardens. A removable lid provides access for cleaning and water retrieval. Choose this RTS model if those access and material features matter more than a collapsible design.
Limitation: It holds less than the 100-gallon option, so users with higher storage needs may need multiple containers or a larger tank.
FCMP Outdoor Raincatcher 4000
Best for: Homeowners seeking a rigid 50-gallon barrel with provisions for adding storage. Its flat-back shape is designed for placement against a home, while the wide opening is intended to make installation easier.
Side spigots allow multiple Raincatcher barrels to be connected in series, making this model a useful starting point for a modular collection setup. Choose it if you want to begin with one barrel and potentially expand capacity later.
Limitation: The initial capacity is 50 gallons. Expanding storage requires additional compatible barrels, so account for the space and connection layout needed.
Laspeiraux 53-Gallon Collapsible Rain Barrel
Best for: Buyers who value portability and the ability to fold a tank for storage. The 53-gallon model is made with three-layer PVC and includes a filter, spigot, and overflow kit according to its listed features.
Its integrated design uses a screw-in faucet, and circular footpads are included to help prevent wobbling or tipping. Choose this tank if a foldable container is more practical for your available storage space than a bulky rigid barrel.
Limitation: It is a flexible tank, not a rigid container. If you need a fixed, hard-sided barrel, compare it with the RTS, FCMP, or Step2 options instead.
Buying Guide: How To Choose A Rainwater Storage Tank
How much storage capacity do you need?
Compare tank capacity with your intended use and available space. A 50- to 60-gallon barrel can suit routine garden watering, while a 100-gallon tank holds more between uses. Actual collection depends on rainfall, roof area, and how the tank is connected, so capacity alone does not predict how quickly it will fill.
Should you choose a rigid or collapsible tank?
Rigid barrels are designed for a fixed outdoor location and may include flat backs for placement near a wall. Collapsible tanks can be folded for storage or transport, but rely on their support structure to remain upright. Choose based on where the tank will be installed and whether you need to put it away when not in use.
Which inlet, outlet, and overflow features matter?
Look for features that match your collection setup: a filter or mesh screen, a spigot for dispensing water, and an overflow route for excess water. If you plan to add tanks later, check whether the product specifically provides connections for linking multiple barrels. Position any tank so overflow can be managed appropriately.
What should you check before installation?
Measure the installation area, including room for the downspout connection and access to the spigot. Review the tank’s shape, capacity, lid or opening, and included accessories. A full tank is heavy, so select a stable location and follow the product’s setup instructions.
