For most municipal, commercial, or streetscape projects, a good-quality urban planter box typically costs about $200 to $700 per unit. Small, simple powder-coated metal or HDPE planters may start around $100 to $250, while mid-size commercial-grade fiberglass, steel, or aluminum planters generally run from $300 to $800. Large architectural planters, custom sizes, integrated irrigation, or high-end finishes can cost $900 to $2,500 or more.
The main factors that affect the price are material, size, drainage and irrigation features, custom fabrication, shipping, and installation. For a reliable budget, expect around $350 to $600 per planter for standard commercial quality. However, final pricing can vary by region and project quantity, so it is best to request quotes from several suppliers before making a decision.
