Extreme Storm Shelters Now Available Exclusively at Select Lowe’s Stores
Selecting the Right Storm Shelter is Easy
Indoor or Outdoor?
Big prefabricated storm shelters cannot fit through a door. If your home is built on a suitable concrete pad, you may select the ExtremePanel above ground storm shelter. If a house is being custom-built around a storm shelter, you may select any suitable shelter.
Underground or Above Ground?
Whether to install an underground or above ground storm shelter will depend upon several factors including your preference, budget, and site selection. Some areas cannot reasonably be excavated due to rock and soil conditions. Zoning constraints may also determine the type of shelter you may have installed at your residence.
Size & Occupancy
Customer preference, zoning regulations, practical space considerations, site selection, shelter type, the number of occupants of the home, size of occupants, and budget are all factors that will impact how large of a shelter you should install at your home. Shelters should be selected that are large enough to accommodate all occupants of the home.
Extreme Storm Shelters may be purchased with or without installation. Note that if you elect to have someone else install the shelter, it is your sole responsibility to ensure that the installer is qualified and capable of installing the shelter as per manufacturer’s specifications. Delivery within 50 miles of an Extreme Storm Shelters distribution center (not the local Lowe’s store) is included in the price of installation. An additional cost of $2.30 per loaded mile applies to all deliveries outside of this 50-mile radius of an Extreme Storm Shelters distribution center.

Will Extreme Storm Shelters install my tornado shelter, or will I have to install it myself?
You can purchase a storm shelter from Extreme with or without installation. Our experts have years of experience in proper shelter installation. If you choose to engage a third party to perform your shelter’s installation, please know that it is your sole responsibility to ensure that this installer does the work correctly according to the manufacturer’s specifications.
What is the best time to invest in a storm shelter?
At Extreme Storm Shelters, we believe that the best time to purchase a tornado shelter is today! Although tornado season peaks in the spring, the truth is that tornadoes can strike on any day of the year. Don’t wait until severe weather is bearing down on you to make this critical, potentially life-saving decision. Between the months of September and February, shelter providers experience a slower season, which makes this an ideal time to plan for the future.
Where is the best place to install a storm shelter on my property?
Extreme can install our storm shelters in almost any location. We have a range of different models. Some are ideal for basements, others for garages, while still others can be placed outside, above or below ground. If you aren’t sure about the best solution for you, Extreme Storm Shelters will be happy to advise you.
What if my house collapses on my shelter during severe weather?
Extreme Storm Shelters has prepared for this possibility. That’s why we include our proprietary GeoLocator Service with every shelter we sell. If a severe weather event strikes your area, we will attempt to reach you from our call center to ensure that you were able to safely get to your storm shelter. If we are not able to communicate with you or your emergency contacts, we will contact emergency crews and give them the exact GPS coordinates of your shelter so they can find you and provide any necessary assistance.
Do I really need a storm shelter if I already have a basement or a room in my house with no windows?
The strongest tornadoes have winds that can exceed 250 mph. These twisters can demolish houses in seconds. Flying debris from tornadoes has been known to puncture wooden beams more than eight inches thick. The safest severe weather solution for your family is a dedicated storm shelter. Extreme Storm Shelters’ residential storm shelters have been tested to withstand the wind forces of an EF5 tornado. And all of our shelters are made to be compliant with FEMA 320 standards.
Does it take a long time to install a storm shelter?
Not at all. Extreme Storm Shelters can normally install an underground storm shelter within a single day. And in most cases, we can install an above ground shelter in around four hours.
Will storm shelter installation mean a huge mess in my home or on my property?
Absolutely not! The professionals at Extreme Storm Shelters will thoroughly clean up the installation area once their work is complete. We aim for 100% customer satisfaction in everything we do from start to finish.
Will I be able to enter my ExtremeGarage unit while my vehicle is parked in the garage?
Yes. Extreme Storm Shelters installs our ExtremeGarage shelter units 2 feet from the edge of your garage. This will ensure that you have sufficient room to access your shelter.
Will Extreme Storm Shelters require a deposit when I make my storm shelter order?
Yes, Extreme does require a $500 deposit when you place your order. This will guarantee you a position in our delivery queue. If you order your storm shelter through Lowe’s, they will require you to make a full payment at the time of your order. Consult Lowe’s to learn more about their financing options.

Here are just a few of the benefits of this model: 1) We encase each ExtremeGarage unit in 5 inches of concrete during installation to mitigate against floating; 2) The ExtremeGarage model has an oversized door for a more aesthetically-pleasing look; 3) Removable steel benches and steps come standard with this model, as do a storage locker and winch; 4) This unit is made with the prevention of galvanic corrosion in mind; 5) The ExtremeGarage has the strongest lid in the storm shelter industry; and 6) Every ExtremeGarage includes our trusted GeoLocator Service.

Does Extreme have a lot of experience in manufacturing and installing storm shelters?
We’re glad you asked! Our company has produced thousands of shelters for both residential and commercial clients. When it comes to installation, we have successfully managed projects in the range of several million dollars. Yet we’re still proud to provide personalized customer service to all of our clients, no matter the size of the job. Experience counts. Trust Extreme Storm Shelters.
Will I have to worry about condensation in my underground tornado shelter?
Condensation is always a possibility with underground shelters especially in humid climates. With this in mind, all shelters from Extreme Storm Shelters incorporate a cross ventilation design and come standard with a free moisture remediation kit.
What's the best way to combat condensation in an underground storm shelter?
There are several ways to deal with the issue of condensation in underground storm shelters. One way is to circulate air throughout the unit. You can also use a dehumidifier or a moisture remediation kit (included with the purchase of any underground shelter from Extreme Storm Shelters).
Are all storm shelter models made by Extreme Storm Shelters compliant with FEMA 320 guidelines?
Absolutely! All of Extreme’s residential storm shelters are FEMA 320 compliant.
Are storm shelters from Extreme ICC 500 compliant?
Yes, all of Extreme’s storm shelters are ICC 500 compliant.
Have Extreme Storm Shelters' units undergone any controlled testing to prove their strength?
Yes! In fact, all of Extreme’s shelters have undergone extensive testing. They have withstood EF5-level winds (speeds greater than 200 mph) produced at Texas Tech’s National Wind Institute.
Would Extreme's shelters withstand an EF5 tornado?
Absolutely. Extreme Storm Shelters believes in testing our units thoroughly to ensure that they will hold up when you need them the most, even during the strongest tornadoes. We are proud to be a member of the National Storm Shelter Association (NSSA). No shelter manufactured by a member of the NSSA has ever failed during a tornado.
How deep in the ground will I have to bury my underground storm shelter?
At Extreme, we bury our underground storm shelters 12 inches below the surface of the ground.
Could I install one of your tornado shelters myself?
It is certainly possible for you to install your own storm shelter. There are many online resources that can help you to do this. You could also engage the services of a third-party installer. That said, if you enlist the professional installers from Extreme Storm Shelters to perform the installation for you, then you’ll be 100% certain that your shelter has been properly placed.
Does Extreme offer a warranty on your shelters?
Extreme Storm Shelters offers a limited lifetime warranty on all of our shelter units.
Why are your steel tornado shelters better than the concrete tornado shelters sold by other companies?
At Extreme Storm Shelters, we design all of our steel shelters based on a proprietary leak test to guarantee that none of our units will ever leak. Concrete, on the other hand, will always crack and leak eventually, and concrete retains moisture even under normal circumstances.
What makes Extreme's steel shelters better than others' fiberglass shelters?
Steel storm shelters are superior to fiberglass shelters in a number of ways. Most of all, steel storm shelters are stronger. Fiberglass shelters cannot withstand EF5-level winds, so there are no above ground fiberglass shelter units. Even underground fiberglass shelters will eventually crack due to the pressures of their subterranean placement.
How does Extreme ensure that your storm shelters won't rust?
At Extreme Storm Shelters, we chemically treat all of our units to prevent them from rusting. We are the only storm shelter manufacturer to powder coat all of our above ground models and the interior of our underground models. Powder coating creates a more durable finish than regular paint, making it the better choice for protecting your shelter. Extreme also caulks our underground shelters and coats them with 15 mils of coal tar epoxy. We then seal all of the joints. The result is the same as if the shelter was dipped in rubber. You can count on Extreme Storm Shelters’ units not to leak or rust, above or below ground.
What if lightning strikes my storm shelter?
An Extreme Storm Shelter unit is actually a very safe place to be during a lightning storm. You cannot be electrocuted in one of our storm shelters, even if it is struck by lightning. The reason for this is that the steel shelter basically acts as a Faraday Cage (this type of enclosure is named after its inventor, Michael Faraday). If your unit is struck by lightning, the charge is distributed throughout the exterior, leaving the interior shielded from the charge. You can see this same principle in effect in the metal suits (the Faraday Suits) that linemen wear to protect themselves when working on high-voltage electrical lines. The bottom line: You will be safe from lightning strikes inside an Extreme storm shelter.
Are Extreme Storm Shelters' units accessible to persons with physical disabilities?
Yes. Extreme’s storm shelters are ADA accessible and come with a 32-inch door opening to accommodate individuals with disabilities.
Will I be able to open my storm shelter's door if it gets covered in debris?
Extreme Storm Shelters has planned for the very real possibility of debris covering our units and blocking shelter doors after violent storms. That’s why we have designed some of our units to have doors that swing inward instead of outward. For other units, we offer the option to install a jack to help open the unit’s door in case it gets blocked by debris. As an additional safety measure, Extreme also provides our GeoLocator Service with every shelter we sell.
Will I be able to use my cell phone inside one of your shelters?
Yes, your cell phone will function inside an Extreme storm shelter. However, please be advised that tornadoes may destroy cell phone towers in your area, which would likely adversely affect your service.
Do Extreme's storm shelters have electrical service entrances?
Nearly all of Extreme Storm Shelters’ units have a 3/4-inch conduit entrance to accommodate power, cable, and phone connections. The only exception is the ExtremeGarage unit, which is fully embedded in concrete in the floor of a garage bay.
How many states have Lowe's locations that sell Extreme's storm shelters?
You can purchase an Extreme storm shelter to protect your family at home or the workers at your small business at Lowe’s locations in Alabama, Arkansas, Oklahoma, Tennessee, and Texas.
How does Extreme secure your units to concrete slabs or floors?
At Extreme Storm Shelters, we design every aspect of our shelters with your safety foremost in our minds. And anchoring your unit to its concrete foundation is no exception. We make certain that our units are installed on a concrete foundation that is 4 inches thick, and we ensure that none of our anchors have an embedment length exceeding 3 inches. (If the anchor is embedded deeper than this, the anchor will most likely be exposed to the soil below the foundation, thereby voiding any warranty.)
We use 3/8-inch x 3-inch embedment ITW Redhead anchors every 12 inches on our shelters. Each anchor has an ultimate tension (pullout) strength of 5,940 pounds. Our ExtremeCube 6×4, for example, is anchored with 20 ITW bolts with a holding power of 118,800 PSI. Our smaller ExtremePod is anchored with 12 ITW bolts yielding a holding power of 71,280 PSI.
Where can I install an ExtremePod or an ExtremeCube on my property?
Both the ExtremePod and the ExtremeCube models can be placed in most garages, carports, or patios. For customers serviced from one of Extreme’s more than 140 Lowe’s locations, we can provide a complimentary site visit to verify that your concrete will meet specifications. If it does not, we can pour a proper concrete pad for an additional fee.
How can I be sure that the door on my storm shelter won't fly open during a tornado?
At Extreme, we equip all of our tornado shelters with a 3-point locking system. This means that even if one of your door’s locks is compromised, there will be two backups in place to keep the door secured.
Does Extreme Storm Shelters offer any financing?
Extreme wants to make sure that our shelters are accessible and affordable for as many people as possible. To make this happen, we have partnered with several banks and credit unions to help provide a range of financing solutions. Additional storm shelter financing options are also available through Lowe’s locations.
Will Extreme Storm Shelters be able to offer financing to customers with poor credit?
Extreme strives to help all of our customers get the shelter financing they need to protect themselves and their families.
Where does Extreme manufacture your storm shelters?
Extreme Storm Shelters is headquartered in Thomasville, Georgia. Our skilled craftsmen work here and also in our satellite factory locations in Alabama, Arkansas, Oklahoma, and Texas. You can purchase Extreme’s storm shelters at more than 140 Lowe’s locations. We also keep our shelters in stock for immediate delivery throughout Tornado Alley and Dixie Alley.
How does Extreme determine the number of people each shelter can accommodate?
Extreme’s shelter occupancy numbers are based on our compliance with FEMA 320 and ICC 500 guidelines. According to these specifications, each occupant should have 3 square feet of space in any storm shelter.
Will I be able to move my above ground shelter if I sell my home and relocate?
Yes! If you move, Extreme Storm Shelters’ factory installation team can re-install your shelter, for a fee, at your new location .
Will a storm shelter add any value to my home?
In most instances, yes. Home appraisers will generally assign additional value to homes with shelters in areas that are especially prone to tornadoes. And homes that have shelters may also be more marketable overall. For instance, a home with a shelter will often sell more quickly than a comparable one without a shelter.
What is the NSSA and why is it important for a storm shelter company to be a member?
Extreme Storm Shelters is proud to be a member of the NSSA. The NSSA is the National Storm Shelter Association. It is a member-directed organization made up of the nation’s leading tornado shelter manufacturers that concerns itself primarily with promoting the production of tornado shelters of the highest quality possible. Members of the NSSA hold themselves to the most stringent engineering and ethical standards and submit their shelters to peer review from other engineers. No shelter manufactured by an NSSA member has ever failed, even during an EF5 tornado event.
Can I lock my tornado shelter's door from the outside?
Yes, you can lock an Extreme Storm Shelter unit from the outside. This is essential, as you may wish to store valuables inside your shelter. In addition, the exterior lock operates independently of the inside lever, ensuring that you cannot accidentally lock yourself inside the shelter with no means of escape.
What items does Extreme recommend keeping inside a storm shelter?
Most Extreme storm shelters come equipped with a bench that houses a lockable storage compartment. This is a great place to keep emergency supplies and other important items. We advise you, at a minimum, to keep the following in your storm shelter: a flashlight, a NOAA weather radio, extra batteries, water, MREs, a first-aid kit with any extra medicines, a horn, necessary insurance documents, and backup copies of any personal mementos such as photos or videos.
What is the occupancy range for Extreme's storm shelters?
Extreme Storm Shelters strives to provide you with the best shelter solution to meet your particular needs. Our shelters range in occupancy from the ExtremePod unit, which can protect up to 4 people, all the way up to the ExtremePanel 6 x 8 and the ExtremeCube 6 x 8 units, each of which can protect up to 16 people.
Do Extreme Storm Shelters' units have vents?
Yes. All of Extreme’s storm shelters meet or exceed FEMA 320 and ICC 500 requirements regarding vents. These guidelines state that all tornado shelters have at least 4 square inches of venting per occupant.
What steel gauge does Extreme use for its storm shelters?
All of Extreme Storm Shelters’ models have been designed and tested to withstand the winds from an EF5 tornado. The steel gauge for each unit depends upon its shape and where it will be installed. Our steel thicknesses range between 10 gauge, 3/16 inches, and 1/4 inches.
Are underground storm shelters safer than above ground shelters or vice versa?
They are both equally strong! At Extreme Storm Shelters, we engineer all of our units–both our above ground and our underground models–to withstand the winds from an EF5 tornado. We want you to pick the model that will best suit your individual needs. If you aren’t sure which shelter will do that, just ask us! We’re always happy to help you find the best way to keep your family safe.
