Tall Extension Kit Add-On - Multiple Heights

More room to grow, designed to last.

The Tall Extension Kit Add-On makes it easy to expand your existing raised garden bed without the need to purchase a new one. Perfectly compatible with Sproutbox’s 9-in-1, L-Shape, and U-Shape beds, this kit instantly adds an additional 1.5 feet of growing space for deep-rooted vegetables, herbs, or flowers.

Crafted from the same premium Magnesium-Aluzinc steel as your original bed, this extension is corrosion-resistant and built to last up to 20 years, 3 to 7 times longer than standard wood or metal. Designed to match in both height and finish, it blends seamlessly with your existing setup, ensuring your garden looks cohesive while giving you the extra room you need.

Each kit includes matching panels, bracing rods, stainless steel hardware, extra rubber safety edging, and a step-by-step instruction guide for stress-free assembly. Choose from three height options (8”, 17”, or 32”) and three timeless finishes: Eucalyptus green, Slate grey, or Pampas off-white, for a customized extension that feels intentional in any space.
