We recently had a customer ask us about underground tornado storm shelters. Here's our reply: We neither recommend nor sell below ground shelters due to the many hazards they pose, such as entrapment, flooding, floating, getting hit with debris while trying to reach safety, critters, leaks....the list is quite long. Plus, from a practical standpoint if you ever move the in ground shelter isn't going with you...it stays with the new owner who won't pay you a dime extra for your investment in the shelter. Our modular design can go with you from home to home so you'll never be without a severe weather and home invasion plan again. You have the added benefit of indoor installation, keeping the unit comfortably climate controlled or at least protected from the elements while accessing it if you locate it in your garage, carport or patio. You can view our safe rooms rated for 5 occupants here. Those two models are called the Defender and the Sentry. Please don't hesitate to contact us if you have any questions. We're here to help. You can call toll free 855-552-7667.
