Why Use EZTube for Your Outdoor Kitchen or BBQ Grill Island?
EZTube’s square aluminum or steel tubing system offers several benefits:
- Significant Cost Reductions and Substantial Savings: Building your BBQ grill island or outdoor kitchen with EZTube is far more affordable than purchasing a pre-built BBQ island or outdoor kitchen, which can cost thousands of dollars. Build the structure yourself to save on markup costs, labor, and more.
- Modular and Customizable: Adjust the size, layout, and configuration to match your outdoor space exactly to spec.
- Durability: Aluminum resists rust, while steel offers high strength for heavier components.
- Easy Assembly: No welding required—simply connect components using the EZTube connectors.
- Professional Look: A clean, industrial aesthetic that complements modern outdoor kitchens.

Step-by-Step Build Guide
Step 1: Plan Your Grill Island Design
Sketch your BBQ island layout, ensuring it accommodates your grill insert, storage, and any additional features like a side burner or prep space. Common sizes range from 5 to 8 feet wide and 2 to 3 feet deep.
Step 2: Assemble the EZTube Frame
- Build the Base Frame: Start with a rectangular frame to support the countertop. Use EZTube corner connectors to secure the square tubing.
- Add Vertical Supports: Attach vertical tubes at each corner and in the middle for stability.
- Create Storage Sections: Use additional square tubing to section off spaces for drawers, shelves, or a propane tank compartment.
- Reinforce the Structure: Use cross braces or extra connectors to strengthen high-stress areas.
