Best Overall: Good Ideas Impressions Eco Palm 50 Gallon Rain Saver

Good Ideas Impressions Eco Palm 50 Gallon Rain Saver


The elegant look, recycled materials, and 50-gallon capacity of this barrel make it our top overall choice. It has a fine-mesh screen to keep debris out, as well as a spigot that attaches to a gardening hose. The lid's well can be used to plant flowers or herbs, and also has a channel system that diverts water to the front of the barrel (away from your wall) in case of overflow.

We also like the grooved, textured look of the barrel, which will add some understated style to your home's exterior, and looks much less utilitarian that many of the other barrels on the market, although new design options are popping up more and more.

Note that a very similar design from Good Ideas is available with brass spigots, however, that option isn't made with recycled materials.

What to Look for in a Rainwater Collection Barrel


Always look at what the rain barrel is made from. Many will be plastic because it’s a good option for holding water, but we like barrels that are also made from recycled materials. If you do find a wine barrel made from wood, be sure it has been sealed well. This can be a big problem with rain barrels—you don’t want them to leak—so don’t be afraid to ask, especially if buying local. 


A lot of rain barrels are going to be in the same size range—around 3 feet tall and 2 feet wide. You want a wide opening for collecting water, so this is a good size. However, you can get barrels that are both bigger and smaller. Keep in mind that rain barrels can get very heavy when they’re filled with water, so bigger isn’t always better. In fact, getting two smaller rain barrels might be better for some people. 

Special Features 

Check the quality of the spigot and see how easy it is to turn on and off. In addition, make sure your rain barrel has a good screen to keep out insects and debris. Both are important components of the overall function of a good rain barrel so you can use it all the time. 

You may also want to consider the style of your barrel, as some are more utilitarian while others have a more decorative finish.

Frequently Asked Questions
  • Can I make my own rain barrel?

    You can definitely make your own rain barrel. This is a good DIY project because you can easily upcycle large containers like a large tote or garbage container to turn into a water collection station. Be sure to find good instructions for this process to keep it secure and leak-proof. In addition, many people will take a plain rain barrel and dress it up by painting it. This is another good option for someone who likes crafting or DIY. 

  • Will rain barrels overflow?

    Rain barrels often come with diverters or overflow hoses that come in handy when you have a lot of water in your barrel. This is actually a good feature to look for when shopping with rain barrels. This way you won’t be creating a big puddle where you’re installing your barrel.

  • Do rain barrels attract mosquitoes?

    They can! Mosquitoes are naturally attracted to pools of water, and a rain barrel is no different. If you make your own barrel, be sure to include mosquito proofing in your design (which will usually involve screens). Most rain barrels you buy from the store will already include this, but make sure you add in screens or seal up anywhere there might be exposed water (like around downspout connections).

  • How much can rain barrels save on watering?

    According to the U.S. Environmental Protection Agency, a rain barrel can save the average gardener around 1,300 gallons of water in a single growing season. Of course, you’ll need a steady flow of rain to make this possible, but it can really save your water bill.

    Plus, it just adds to conversation efforts overall. It’s such a great way to reduce your carbon footprint, because in most places the tap water that you pull from your house's water supply requires a lot of energy to clean and pump.
