17.5" deep for all your favorite plants! Stick with one of our two standard sizes, or create a raised bed of your own ideal length by tacking on an Extension or two.

Corten steel is a unique and durable weathering steel that develops a protective patina of rust over time that safeguards the base metal from corrosion. The steel arrives in its natural grey state and will build its patina over a period of weeks. (If you can’t wait for that rustic appeal, our quick-aging recipe can help you achieve your perfect patina in one afternoon.)

For best results, we recommend filling with 22 bags of our premium potting mixes:
