What to Consider When Choosing the Best Rain Barrel

Since a rain barrel can last a long time and you may use it frequently, it’s important to find a rain barrel that meets your specific needs. Here are some of the top considerations to keep in mind when shopping for a rain barrel.

Size and Capacity 

How much rainwater is needed helps determine the right size rain barrel. In addition, for those looking for the best rainwater collection system with the goal being to use the barrel water for the household’s potable water (safe for drinking), it’ll be important to consider how much water a home uses for cooking, washing laundry, bathing, cleaning dishes, and flushing toilets.

The most popular rain barrels typically hold about 50 gallons of water, which generally won’t be enough for both potable and non-potable water use since the average person in the United States uses about 82 gallons of water a day. However, some rain barrels can hold up to 100 gallons or more to support irrigation and potable water needs.

Material

Since rain barrels are located outside, it’s essential that the barrel material can hold up well throughout the seasons in the local climate. Harsh summer sun and colder temperatures can affect the longevity of some barrel materials if they are kept out year-round.

Most rain barrels today are made of plastic, some of which is recycled plastic. The benefit of plastic is that it adds UV protection and durability to the rain barrel. However, for those who want a more sustainable option and don’t mind paying higher prices, there are rain barrels made from wood.

Design

Rain barrels are similarly barrel-shaped, but some have unique designs to better complement a home’s style or act as a decorative piece while also being functional. Some are shaped like flower pots, and flowers can be planted on top, while others have a stone, wicker, or wood texture to add a decorative touch to a property.

Another design feature that is important is the location of the spigot on a rain barrel because that’s how the water is dispensed. Think about how the rain barrel will be used and whether it will need to be attached to a pump or hose for watering. Some rain barrels sit on stands to make accessing the spigot easier.

In addition, most rain barrels have an overflow valve or rain barrel diverter. This allows users to connect the barrel to a downspout so that if the barrel gets full, it simply diverts the excess into the downspout, just like it would if the barrel wasn’t there. It’s also possible to connect a few rain barrels together to collect the overflow water. The overflow valve is important because it can be inconvenient and potentially problematic for a barrel to overflow and cause water pooling around a home’s foundation.

Filtering Screen 

A filtering screen helps keep debris out of collected rainwater, which is important whether or not users are collecting potable water. Debris such as leaves, twigs, and pine needles can quickly clog the spigot or hose, preventing users from getting the water out of the barrel for use.

Look for rain barrels that have some type of filter to prevent debris, especially for those who live in an area with a lot of trees. Keep in mind that for those who will be using rainwater for potable uses, such as cooking and showering, an additional filter system will need to be in place.

Safety

Rain barrels can weigh a lot—a 50-gallon tank that’s full can weigh more than 400 pounds, not including the rain barrel itself. As it can be dangerous for a rain barrel to tip over or be in a position where it could hurt someone, a rain barrel needs to be safely installed on a level surface and connected to a downspout. Never attempt to move the rain barrel when it is full.

Look for rain barrels that can be installed on top of a platform or those that sit against the wall with a flat back to minimize the chances that a rain barrel will tip or need to be relocated while it’s full or mostly full.

Best Overall

This 50-gallon rain barrel is designed to look like an old wooden oak barrel but with the durability and rot and fade resistance of plastic. The manufacturer also makes a stand that can be purchased separately, which makes using the spigot easier as it’s pretty low to the ground. The position is suitable for attaching a hose but isn’t convenient for a watering can or jug.

The back of the rain barrel is flat so it sits snugly against a wall, helping to save space and making the rain barrel a bit more discreet. However, it can bulge out when full. It has dual overflow valves and can be connected to other rain barrels to collect even more rainwater.

Product Specs 

  • Capacity: 50 gallons
  • Material: Plastic
  • Weight when empty: 18 pounds

  • Flat back sits flush against the wall
  • Resistant to rot and fading

Although it doesn’t sit quite as flush against the wall as our best overall pick, this rain barrel does come with a flatter back to sit up against a home, garage, or shed for a more cohesive look. Designed to provide the appearance of a traditional oak barrel with the durability of resin, this rain barrel is more resistant to freezing temperatures in case the rain barrel will be outside year-round.

For those looking for a more affordable rain barrel, this 55-gallon option from FreeGarden may be worth considering. It’s available in different colors, including a striking green, and has a square construction.

This rain barrel also comes with an extension hose and child-lock screws for the lid. A strategically placed spigot means users don’t need to purchase an extra stand or haul concrete blocks to put underneath the barrel in order to fill up a watering can.

Upgrade Pick

The Best Rain Barrels Option: Aunt Molly’s Barrels Whiskey Barrel Rain Barrel

If an upcycled option made of real wood is desired, this upcycled whiskey-barrel-turned-rain- barrel from Aunt Molly’s Barrels could be a choice pick. The barrel comes with a downspout connector, three spigots, and even a drain with a plug on the bottom.

Since the barrel is made from real wood, if it dries out, the wood can shrink and crack, so it’s important to keep some water in this barrel at all times. However, should the wood dry out for any reason, it can usually correct itself by holding water for a few hours.

The rain barrel is also heavy, so caution must be used when installing and moving it. Since the spigot is lower to the ground, a stand may be needed if using the barrel with a watering can.

Product Specs 

  • Capacity: 53 gallons
  • Material: White oak
  • Weight when empty: 105 pounds

Pros

  • Made of real wood
  • Upcycled
  • Comes with everything needed to install it
  • Attractive and authentic look

Cons

  • Heavy
  • Prone to rotting, insect damage, and leaks
  • Spigot is low to ground

When looking for a smaller rain barrel for a home, this 35-gallon option comes in two color choices and mimics the look of a traditional rain barrel. Besides being resistant to rust and corrosion, it also has a planter on the top so users can plant flowers or herbs to create a decorative rain barrel that’s also functional.

When using the planter at the top, plants can easily get flooded, so they may need to be kept in their pots. Like other rain barrels, the spigot is low to the ground, so users may need to place the barrel on a stand if they want to use it with a watering can.

Product Specs 

  • Capacity: 35 gallons
  • Material: Plastic
  • Weight when empty: 19 pounds

Pros

  • Comes with debris screen
  • Small construction makes it easy to place
  • Barrel is resistant to corrosion and insect damage

This decorative rain barrel is textured and designed to look like the trunk of a palm tree. It comes with a self-draining planter on top for flowers, herbs, or plants and is made from 100 percent recycled BPA-free polyethylene, which is a type of plastic.

The barrel also has a built-in overflow management system, dual spigots, a mesh screen to keep out debris, and a 50-gallon capacity. Although the front spigot is low to the ground, it does have a second side spigot that can be used for watering cans or 5-gallon buckets.

As a result of its decorative and textured appearance, it doesn’t look like a rain barrel, making it a worthy consideration for those who don’t want a barrel in their garden or yard.

To choose the best rain barrels, we evaluated each product’s features, price, materials, and capacity. We evaluated the design of the barrels, including filter screens, overflow spouts, and spigots to determine which models were the easiest to use while still holding up to the elements.

Although aesthetics weren’t a priority when evaluating front-runners for the best rain barrels, they were a consideration since rain barrels are often outdoor components located in plain sight. Overall, the highest-rated products with the most convenient features and the best durability were chosen for this list.

Tips for Rain Barrel Use and Maintenance 

Rain barrels are designed to be outside and to weather the elements. However, most manufacturers suggest keeping a rain barrel inside and turned upside down during the off-season. Consider storing a rain barrel in a shed or garage during the winter to protect it from freezing temperatures if it’s not being used. Always clean a rain barrel before storing for best results.

In addition, when connecting a hose to the spigot of a rain barrel, be sure the hose is below the water level of the rain barrel for the water to flow properly. Users also have the option of not using a hose and instead filling a jug or watering can with the collected water.

  • Always install a rain barrel on a stable, flat surface.
  • Connect a rain barrel to the downspout for overflow to prevent water pooling.
  • Never use collected water for potable (drinking or cooking) purposes without filtering it first.
  • Drain barrels before freezing temperatures are expected.
