DIY Concrete Fire Bowl (Cheap & Easy): Simple Guide

Making a concrete fire bowl is simple and affordable. Use two plastic bowls (one large, one small). Lubricate them, then fill the gap between them with high-strength mortar. This creates a simple, effective fire bowl form.

Materials Needed

• Two plastic bowls: One large, one small (smaller fits inside larger)
• High-strength mortar: Not regular concrete mix
• Release agent: Cooking spray or mold release

Step-by-Step Process

1. Prepare bowls: Clean bowls thoroughly
2. Lubricate: Apply release agent to both bowls
3. Position: Place small bowl inside large bowl (centered)
4. Create gap: Gap between bowls creates bowl wall
5. Fill gap: Fill gap between bowls with high-strength mortar
6. Consolidate: Tap or vibrate to remove air
7. Let cure: Allow mortar to cure completely
8. Remove forms: Remove both bowls

Why High-Strength Mortar?

High-strength mortar is needed:

• Heat resistance: Withstands fire heat
• Stronger: More durable than regular mix
• Required: Regular concrete may crack from heat

Tips for Success

• Use release agent: Essential for easy removal
• Ensure gap: Make sure gap is even all around
• Support small bowl: Keep small bowl centered while filling
• Cure completely: Allow full cure before removing forms

Make a concrete fire bowl using two plastic bowls (one large, one small). Lubricate them with release agent, then fill the gap between them with high-strength mortar. The gap creates the bowl wall. Use high-strength mortar for heat resistance. This simple method creates an affordable, functional fire bowl.
