The last time we looked at luxury end-of-the-world shelters was with Vivos Group's communal model. That was where you pony up 35 grand and basically share an underground five-star hotel with 79 other people. But the well-heeled among you may prefer your own digs, and for that you'd turn to Texas-based Rising S Bunkers.

"Rising S Bunkers is America's biggest manufacturer of ALL steel underground bunkers, storm shelters, safe rooms, blast doors, and bomb shelters," the company states. "We lead the industry in innovation and engineering underground shelters."

Their top-of-the-line offering is the Luxury Series, where buyers can choose from the following models:
