Bunker Plans, Pricing & Features

Our Proprietary Engineered Design is what makes our Bunkers, Gun Vaults, Shooting Ranges and Safe Rooms the Strongest and Most Secure!

We put our Main Structural Frame on the inside where it’s safe and well protected from outside water and moisture and a 1/4 thick steel plate on the outside so our bunkers will never rust.

With 1/4′ thick steel skin on the outside and a heavy coat of Epoxy Coal Tar Coating on the exterior, we guarantee that ALL our Ultimate Underground Bunkers will last a lifetime!

Ultimate Bunker manufactures high quality 100% steel Underground Bunkers for small or large families, groups and businesses.
