Buyer’s Guide: What to Consider
Choosing the right small rain barrel involves balancing capacity, material, design, and extra features. Here are five key factors to keep in mind when making your decision.
- Capacity: Consider how much water you need. Smaller barrels (45-50 gallons) are easier to place and manage, while larger ones (66 gallons) store more but take up more space. Choose based on your garden size and rainfall.
- Material: Rigid polyethylene barrels are durable and UV-resistant, while collapsible PVC models offer portability and easy storage. Think about your climate and how long you plan to keep the barrel outdoors.
- Design: Flat-back barrels fit snugly against your home, saving space. Slim-line designs are ideal for narrow areas. Collapsible barrels fold flat for off-season storage. Pick a design that matches your available space.
- Features: Look for spigots, hoses, overflow nozzles, and mesh screens. A stand can make filling watering cans easier. Some barrels allow connecting multiple units in series for expanded capacity.
- Installation: Some barrels come ready to use, while others require a diverter kit or spigot installation. Consider your DIY skills and whether you need extra accessories like a downspout diverter.
Conclusion
Small rain barrels are a smart way to conserve water and reduce your environmental footprint without taking up too much space. Whether you prefer a collapsible model for portability or a rigid flat-back design for durability, there is an option here for every garden.
For most homeowners, the FCMP Outdoor Catalina offers a great balance of style and function, while the Thorkok 66-gallon is ideal if you need extra capacity. Consider your space, water needs, and budget to find the perfect fit.
