  • The material: the type of material will affect how you use the barrel. For example, if you’re just using the rain barrel for gardening, a material like wood or PVC would be just fine. However, if the rainwater is for indoor use, a BPA-free barrel would be best. You can check out BlueBarrel’s HPDE food-grade barrels.

How Long Do Rain Barrels Last?

All materials have a lifespan; some can last hundreds of years while others only last ten years. 

Depending on the material you use, your rain barrel can last from 20 years to 100 years. Here are some materials that you can choose from: 

  • Wood barrels: most wooden barrels can last between 3 – 5 years. However, if you treat the wood, the lifespan can be prolonged to around 12 years. 
  • PVC barrels: PVC stands for polyvinyl chloride. These barrels can last between 25 – 40 years, depending on their exposure to the sun. 
  • Stainless steel barrels: stainless steel is rust-resistant but will last 25 – 50 years before deforming or rusting.
