Once you get to around 10 feet underground, the temperature stays constant at approximately 55 degrees (F)- a bit nippy, but you won’t freeze (and you won’t cook, either). ATLAS SURVIVAL SHELTERSĪtlas Survival Shelters specializes in corrugated tube shelters the company claims are “the only bunkers tested against the effects of a nuclear bomb.” The interiors of the shelters are comfortable, with the look of an attractive RV with a ton of storage space. Each fills a unique niche some are better as bomb shelters, while others are intended as storm or fallout shelters.

The big question literally comes in many shapes: What is the best shape for a shelter? There are round steel shelters, round corrugated steel shelters, concrete shelters, square shelters and other options to choose from. This isn’t some repurposed, moldy and leaky Cold War-era missile silo (although those do pop up for sale occasionally … missile not included), but a state-of-theart shelter for you and your family. If you’re so inclined, they can even construct a multi-family underground dwelling. This is the relatively cheap option, but if you have the scratch to spare, they will custom-design and build a shelter to suit your needs. There are plenty of companies willing to sell you prefabricated underground shelters or bomb shelters (these two are not the same) and install them on your property. Of course, your cave now comes with flushing toilets, showers, queen-sized beds, a flat-screen TV and a year’s worth of rations. Your ancestors lived in caves and now you might be thinking it wasn’t such a bad idea after all.
