Bunker Plans, Pricing & Features

Our Proprietary Engineered Design is what makes our Bunkers, Storm Shelters and Safe Rooms the Strongest and Most Comfortable.

We put our Main Structural Frame on the inside where it’s safe and well protected from outside water and moisture so your bunker 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 your new Ultimate Underground Bunker will last a lifetime!

Ultimate Bunker manufactures high quality 100% steel Multi Family Bunkers for large families, groups and businesses.
