Our PVC Square Planter has been made with composite PVC material, which does not rot, chip, peel, or powder. Our PVC planter has been made with 1/2" thick PVC, which looks and cuts quite a bit like real wood. Cellular PVC is the perfect choice for planter material as it is naturally resistant to water and moisture, and will not deteriorate over time. This PVC Planter Liner comes with drainage holes, and can be customized to fit your specifications as well. Call us to get a quote at 800-896-0978.
