Common questions about storm shelters

What is a storm shelter?

A storm shelter is essentially a room or structure made to resist outside forces. They are sometimes called “safe rooms,” and while a storm shelter and a safe room are similar, there are certain differences worth pointing out to help you make the right purchasing decision.

  • Storm shelters and tornado shelters: Storm shelters, or tornado shelters, are underground or above-ground rooms made to resist high winds, object impact, shifting foundations, flooding and heavy rains. They are not regulated by the federal government, but manufacturers typically make their shelters to specific industry certification standards to ensure they’ve been tested to withstand these specific conditions. The term “storm shelter” is an ICC-500 designation.
  • Safe room: A safe room is essentially the same type of room as a storm shelter. The term “safe room” is a FEMA designation.
  • Panic room: While a panic room is a kind of shelter, it’s not designed for storms. A panic room is designed to protect you during home invasions. These rooms lock from the inside and are designed to resist gunshots and large amounts of force, meeting certain levels of ballistic resistance standards. You can convert a panic room to a storm room by sealing it and making it a waterproof shelter and making sure all sides (including floors and ceilings) are reinforced.

How much does a storm shelter cost?

A storm shelter can cost anywhere from $2,500 to $20,000, depending on the type of shelter you want. A storm shelter can cost anywhere from $2,500 to $20,000, depending on the type of shelter you want. There are numerous factors that determine storm shelter cost, including materials, location, size, features and more. Here are some general storm shelter prices to give you an idea of what you can expect to pay.

  • Garage shelters: If you want an underground storm cellar in your garage, you can buy a small shelter for $3,000 to $6,000, not including installation. The storm cellar cost is cheaper if you choose a small size, but you’ll pay more for installation than any other type of cellar because you’ll need to rip out the concrete in your garage. It’s usually cheaper to install these types of shelters when you’re constructing a new home.
  • Above-ground storm shelters: Most above-ground storm shelters cost between $2,000 and $8,000. This price will pay for a basic shelter, but you can add features like shelves and seats for additional costs. These can be made of concrete, welded steel sheets or reinforced concrete.
  • Custom yard shelters: Storm cellar prices rise the more you customize your shelter. Custom yard shelters cost anywhere from $6,000 to $25,000, depending on size. A tornado bunker with extra space and shelves for equipment will cost more than an average yard shelter.

What are the most common storm shelter sizes?

Storm shelter sizes vary depending on location and the price you’re willing to pay. While you can usually customize your shelter to fit your space, some companies offer set sizes for below- and above-ground storm shelters. Here are some of the more popular sizes.

  • Small storm cellars: Most garage storm cellars are smaller than yard storm shelters. These usually measure about 3 feet by 6 feet by 5 feet. They can fit about four to six people.
  • Regular storm shelters: Regular-sized storm shelters measure about 4 feet by 8 feet by 4.5 feet. These sizes are more common in yard shelters and can fit about six to eight people.
  • Large storm shelters: A large storm shelter averages are 5 feet by 8 feet by 5 feet. These shelters, mostly reserved for deluxe outdoor shelters. Shelters of this size can accommodate up to 14 people.

Which certificates denote safe storm shelters?

National Storm Shelter Association Executive Director Ernst Kiesling and Assistant Research Professor Larry Tanner study the safety of tornado shelters at the National Wind Institute at Texas Tech University. They gave us some tips to help you choose the safest shelter for your family. While there are no government-required certifications or agencies that make storm shelters official, there are many agencies that offer guidelines for specific engineering, installation and inspection standards.

Kiesling notes you should be wary of any company that claims their shelters are “FEMA-approved,” “FEMA-certified” or “NSSA-certified,” since none of these organizations certify shelters; they just have established guidelines that manufacturers use to build storm shelters. Look for shelters that meet the following standards to make sure your new storm cellar is safe.

  • National Storm Shelter Association (NSSA): The NSSA is a membership-based organization for storm shelter manufacturers. Companies that comply with the NSSA’s Standards Compliance Verification Process can affix a specific seal to their shelters. The NSSA seal tells you the company has passed inspections and secured necessary permits.
  • International Code Council (ICC) 500: The ICC 500 is a list of guidelines for design, testing and occupancy of hurricane and tornado shelters.
  • Federal Emergency Management Agency (FEMA): The FEMA P-320 outlines best practices for foundation setting, shelter placement and reduction of flood risk in residential shelters. The Federal Emergency Management Agency P-361 outlines installation practices, emergency plans, design plans, documentation and maintenance for residential and commercial shelters.
  • Shelter door: The most important part of the storm shelter is the shelter door. For a storm shelter to meet the most basic needs, its door needs at least three locks, and it should be heavy enough to require three hinges.
  • Testing: You should only consider purchasing storm shelters if they have been tested. The FEMA P320/P361 guidelines state that each shelter should be tested in an ISO 17025 accredited lab. You should ask any storm shelter dealer or manufacturer to provide proof of testing on any storm shelter you’re thinking of purchasing.

What should you keep in a storm shelter?

After you purchase your storm shelter, you’ll need to stock it with materials to use in the event of an emergency. Knowing what to keep in a storm shelter will come in handy in case you’re stuck there for a while. The following items should be on anyone’s storm shelter checklist.

  • Nonperishable foods: Keep some nonperishable or canned foods in your storm shelter to make sure you have something to eat in case the storm causes you to go without food. Store some bottled water as well so you don’t get thirsty.
  • Storm shelter equipment: You’ll need some standard equipment in your storm shelter in case you lose power. A weather radio, flashlights and other battery-powered lights are necessities.
  • Hygiene items: You don’t know how long you’ll be in your storm shelter, so bring a few toiletries like toilet paper, hand sanitizer, tissues and about a five-gallon bucket for an emergency toilet. You’ll also need a first aid kit in case of injuries.

Types of storm shelters

Garage storm shelters

The garage is one of the safest storm shelter locations you can choose. An underground storm cellar in a garage is typically made of concrete or fiberglass and installed in the floor of your garage. Garage storm shelters take up less space, but they’re more susceptible to flooding and corrosion. Also, take into account whether you’ll have time to move your vehicle from over the shelter when a storm hits.

Above-ground storm shelters

Above-ground storm shelters are typically made of quarter-inch steel plates that are bolted together. Larry Tanner at the National Wind Institute explained to us that a crew brings the plates to your home and assembles them on-site, then anchors to an approved foundation system (like a reinforced foundation slab). An above-ground steel storm shelter can withstand wind and debris from the most destructive category of tornado (EF5), with wind speeds greater than 200 miles per hour. Above-ground storm shelters can also be made from other materials including concrete (either pre-cast or cast-in-place), reinforced concrete masonry and insulated concrete (ICF).

In-ground storm shelters

In-ground shelters are yard shelters that are typically made of concrete or fiberglass. They are installed directly in the ground outside your home. In-ground storm shelters are different from in-ground storm shelters. You install an in-ground shelter so that half of it is above the ground and half is below. in-ground tornado bunkers are installed completely underground. Both types have ventilation caps — the kind you’d see on the roofs of houses — on top, allowing for normal airflow. Tanner tells us that consumers should avoid in-ground shelters if they live in a floodplain because the shelter can flood and pop out of the ground.

Commercial and school shelters

Many companies build custom above-ground shelters for businesses and schools. Often these large shelters can hold hundreds of people. They are usually made out of steel.

Storm shelter materials

Concrete storm shelters

Concrete is one of the most common options for shelters, especially if they’re in- or above-ground. Since concrete is so heavy, concrete shelters are more or less immovable. Even above-ground concrete shelters don’t need much additional anchorage. They can be bulky, though, which makes them hard to install in small backyards or homes with limited access to the backyard.

Steel storm shelters

Steel shelters are normally installed above ground, and more often than not they’re built piece by piece. According to Tanner, these shelters are typically powder-coated or painted, so you won’t need to worry about rusting. He also mentioned that steel storm shelters are ideal for small backyards or homes with accessibility issues because they are easy to set up. As a bonus, if you move, your steel shelter can be taken apart and reassembled at your new home.

Fiberglass storm shelters

While the thought of a fiberglass storm shelter might not be as appealing as one made of concrete or steel, fiberglass shelters undergo the same testing and many are just as safe. They are made from a mold which helps them resist leakage. Fiberglass storm shelters are generally used underground only.

Polyethylene storm shelters

Some in-ground storm cellars are made of high-density polyethylene. This material is a dense rustproof and waterproof polymer that hold up against heavy environmental impact.
