What Is A Bunker

The lexical origin of the word “Bunker” is derived from a Scottish term meaning “bench, seat”. This may seem odd at first glance as this definition isn’t what usually comes to mind when one hears this term.

Moreover, it was also frequently utilized as the abbreviated form “bunk” which literally meant a “bed”.

By combining the Old Swedish term “bunke” which referred to boards used to guard a ship’s cargo and the original concept of “protected sleeping quarters”, one can better understand why this term eventually developed into our modern notion of a survival bunker.

It’s important to remember that building a bunker is not the same as creating a “She-Shed” or “Man-Cave”. These are typically backyard sheds where ladies have lunch and men watch sports with snacks. A bunker, however, is an effective self-defense structure meant for protection against unpredictable situations.If you want to protect yourself from those who would do you harm, having a well-built security system is essential. In order for the structure to be effective, it should typically be located underground in order to:

1) By staying concealed, potential attackers are unable to identify and target your resources.

2) Steer clear of any potential air-borne threats (including bombings, nuclear radiation exposure, catching illnesses, and other humans).

Ultimately, the main objective in building a homemade bunker is to guarantee safety for your family and loved ones. It should be able to protect them from any harm or disaster that may last long-term. Installing an underground shelter can ensure that you are prepared for such unfortunate events.

When it comes to bunkers, there are 5 primary variants from which you can choose.

1. Industrial

Industrial bunkers are emerging as an increasingly popular way to boost safety and peace of mind in uncertain times. Whether it’s due to natural disasters, societal unrest, or simply the need for extra storage space, industrial bunkers offer a cheap DIY solution for helping to weather whatever storms come our way. The sheer versatility of these prefabricated waterproof compounds ensures that they can be custom-made to fit a plethora of scenarios and applications. With high-quality construction materials, along with sound engineering practices, they provide all the benefits of subterranean safe-havens without the expensive price tag associated with traditional bunker designs. Furthermore, many brands now offer several convenient assembly options making DIY installation a cinch. Industrial bunkers provide an excellent way to safeguard your investments in times of instability and uncertainty—bunkering up never felt so good!

2. Trench

Trench bunkers provide an immensely cheap and effective way to build a bunker of your own. Due to their simplicity, trench bunkers can be do-it-yourself projects that are inexpensive, yet able to sustain protection against significant threats. Trenches offer a variety of advantages as cheap backyard bunkers; depending on the scope of the project, various materials can effectively protect against radiation, blast overloads, as well as a host of extremes in temperatures. For those looking for an affordable solution to building additional fortifications around your property or structure without breaking the bank, creating a cheap diy bunker made with concrete or alternate construction material may just be the perfect solution.

Of course, expert help can always be provided if necessary – but often it’s possible to use preassembled components to create a strongly reinforced bunker with minimal effort or knowledge. Such installations are often chosen not only by militaries, but also by security personnel who need an ultra-secure location for sensitive materials. Whatever your reason, you too can construct your own high quality cheap diy bunker if needed!

4. Artillery

During times of conflict, artillery bunkers have served as essential protection from enemy fire. Constructed using reinforced concrete and steel, these long-standing fortifications can be found around the world. However, their significant expense and heavy labour amount have sometimes made them unfeasible for civilians to build on their own. Thankfully, cheap DIY tutorials for constructing bunkers at home have become widely available recently, which allows hobbyists and preppers alike to construct reasonably priced shelter against possible attacks with minimal effort.

5. Personal Survival Bunkers

Personal survival bunkers have been growing in popularity with the uncertainty of the world. These bunkers provide safe havens from outside forces, natural disasters and even nuclear fallout. Many individuals choose to build their own cheap DIY bunker for added security. Building a DIY bunker can take many forms depending on personal preference; some opt for underground structures while others build structures with unique entrances to hide their location. Regardless of how one decides to construct their bunker, it’s important to equip them with solar power, water filtration systems, air cleaners and food banks to ensure they can sustain life during protection over long periods of time.

Personal Survival Bunkers are an amazing way to protect yourself and your family from a range of disasters. They offer all the essential provisions necessary for protection, like air supply controls, medical supplies and communication devices, as well as extra items, such as fire extinguishers and gas masks.

10 Bunkers From Cheap To Expensive (Pros / Cons)

Now let’s explore the various DIY bunkers you can create. We’ll start with an inexpensive underground bunker and progress up from there!

1. Inside Your House

It’s possible that your house already has the right elements to make a cost-effective, do-it-yourself underground bunker. Here are some creative DIY bunker ideas for your home:

  • Transform your home’s crawl space into a safe, secure area by digging out and sealing it properly.
  • Transform an often overlooked part of your basement into a safe and secure panic room!

When constructing a new home, think of incorporating an in-house bunker into the design. The space beneath the front porch is often used as a secret refuge and provides one of the most cost-effective solutions; however, doing so entails some serious compromises.


  • All the groundwork has been laid, so now it’s your turn to bring this structure to life and make it a safe place for you and yours.
  • With its convenient placement directly beneath the house, you can rapidly escape any situation with ease.

  • Although the concrete floor is yet to be completed, this space has so much potential.
  • By infiltrating the wooden floor from above, an individual could gain entry.
  • Don’t let distance prevent you from protecting your home and family – a bunker separate from the house ensures peace of mind.

2. Backyard Root Cellar

Backyard Root Cellar is an amazing cheap diy bunker that can protect you from wind and storms. With its reinforced walls, insulation, and robust structure, it can keep you safe from external elements of nature.

3. Natural Cave or Burrow

If you are the lucky owner of some land, then you possibly have a piece of property with an empty hole in the ground. You can make use of this natural void and create a cost-effective bunker for yourself! It could be either an old mine or even previously used by wild animals; regardless, it can serve your purpose perfectly.

Exploring a cave can be exhilarating but also risky; there’s no telling what lies within or the stability of its walls and roof. It is wise to have structural support in any case, which applies to all bunkers as well. If your land permits it, you can even dig your own cave!


  • The foundation has already been laid; now it’s your opportunity to build something extraordinary!
  • A single entrance is usually fortified to protect it from unwanted visitors.
  • It’s effortless to disguise oneself.


  • To ensure structural integrity, it’s essential that you secure the walls and roof.
  • Water infiltration could be a critical issue that must not be overlooked.
  • After a solid door is affixed, you will need to create an airway by drilling a tunnel for necessary ventilation.

4. Buried Culvert

If you’re looking to take on a more complex DIY Underground Bunker build, I strongly advise investing in some comprehensive bunker plans. Family Bunker Plans is an outstanding product that provides top-notch bunkers blueprints. For the culvert option specifically, steel culverts are recommended because they have corrugation profiles designed to preserve structural integrity when buried underground.. This makes them ideal for use as your protective escape pod!

Thanks to its ability to withstand intense pressure, culverts are a great option for subterranean bunkers as they can be buried easily and deeply. Once in place, you’ll need to fashion the interior with living and storage areas – not forgetting a secure exit reaching up towards the surface that should ideally be welded together on both ends.


  • This powerful structure can be buried without requiring additional reinforcements.
  • They are available in a variety of sizes and lengths, allowing you to find the perfect fit for your needs.
  • Not only are they cost-efficient, but they offer unbeatable value for money.


  •  With the build-out, you only have access to a limited cylindrical tube.
  • To keep the contents of this container securely enclosed, two openings must be firmly shut.

Height and width could potentially pose a problem.

5. Buried Shipping Container

It’s a piece of cake to get your hands on an inexpensive, used shipping container that can easily be turned into a DIY underground bunker. Rotating out of service containers are available everywhere, and several businesses offer new or pre-owned ones meant for domestic use. Most often these containers are added to property as secure storage spaces for tools and equipment; however, their potential extends far beyond this!

Constructed with steel, a shipping container pre-made with secure doors provides the ideal base for creating an underground shelter. To guarantee it can withstand being submerged in dirt, one must reinforce its walls and ceiling accordingly. Once this is achieved, you are free to design your subterranean abode however your heart desires!


  • The framework is already in place, ready to be explored and realized.
  • For easy installation, just dig a small hole and place it in the ground – simple as that!
  • Joining several containers together is a simple task that can be completed in no time.


  • Even used containers may contain hazardous spills, making them potentially dangerous.
  • To ensure that metal walls and roofs are capable of withstanding burial, they must be reinforced.
  • If you are not constructing the exterior of your desired container, it may cost more in order to get exactly what you want.

6. Above Ground Concrete Blocks

Tap into your DIY self-sufficiency by constructing a cost-efficient underground bunker from the ground up. You won’t need to excavate deeply, so if you don’t have access to machinery, there’s no problem – just grab a shovel and start digging! To get started on the build itself, begin with a solid concrete footing for stability that is mixed with lumber and cement. Then, construct walls layer upon layer using bricks or cinderblocks until reaching your desired height. Finally, create an interior form of rebar support beams before pouring in concrete above as roofing material when finished.

To prevent water seepage, you can attach rubber peel and stick to the outside before backfilling. This way, it not only stays half in and out of the ground, but also gives a seamless look when camouflaged.


  • Construct something grand and unique with your own two hands, brick by brick!
  • Excavation is relatively simple as you only need to dig half of the way down!
  • Can be constructed within the span of seven days or less.


  • Constructing brickwork is strenuous toil, so a scaffold will be essential for achieving the highest point.
  • If you have a barrel mixer, mixing up mortar and concrete by hand or with the aid of machinery will help ensure successful results.
  • To guarantee the above-ground part of the structure is concealed, it’s essential to take precautionary steps.

7. Prefab Bunker

If you’re looking for a secure and well-built bunker, then this precast concrete one is just the thing! Offered in various sizes by several companies, this DIY project requires digging a hole and pouring the cement base. After that’s done, make sure to backfill any exterior spots and install an interior buildout along with a sturdy steel door. With all of these steps handled properly your bunker will be ready to go in no time!

  • To ensure the bunker remains secure, you’ll need to build a solid foundation.

8. Hillside Bunker

Constructing an underground bunker in a terrain that is hilly or sloped can be dangerous and requires additional preparation and expertise. As you delve into the hill, it is essential to reinforce its ceiling with pressure-treated wood or steel for your safety. Once this has been established, you have made yourself a resilient fortification capable of being accessed only from the front entrance; line it up with concrete walls surrounding a sturdy steel door to ensure no one creeps inside!


  • A majestic hill serves as the external skeleton of this edifice.
  • Entry to the building is only allowed through the front door.
  • By using a natural background for your DIY bunker, you create an unnoticeable oasis that blends into the landscape like it was always there.

DIY Bunker Basics

We are concluding this piece of knowledge with some essential information for all your DIY bunker projects. Regardless if you have a budget-friendly underground shelter or an extravagant one, there is certain equipment that should be prioritized and stocked.

Electrical & Lighting

If you want your underground bunker to be lit, it is essential that power is obtained from the grid or via off-grid solutions. And if you wish for additional luxuries like a water pump or ventilation fan, supplemental energy sources must also be considered. In this case, a top quality power station combined with solar panels would suffice.


Everyone deserves fresh air, so it is essential to plan for proper ventilation in your bunker. Install an outlet-vent with a fan that will draw out the stale air and replace it with clean oxygen from outside via an inlet vent equipped with a filter powerful enough to protect against nuclear fallout. To ensure safety and convenience during times of emergency, make sure you stock up on several filters that can be changed out quickly and easily.

Food & Water Storage

When constructing a DIY bunker, make sure to take into consideration the substantial space needed for food and drink items. Canned meats, freeze-dried foods, and home-preserved meals are excellent sources of sustenance during this time. Furthermore, it is essential to factor in enough water for drinking, cleansing oneself–and other hygiene needs–into your plans; I recommend at least storing two weeks’ worth of both food and liquid supplies. Calculate approximately one gallon per person each day when accounting for water intake while using “Daily Calorie Requirement Estimates” as basis when determining how much food you’ll need stored away – if possible aim higher than the minimum 2 week stipulation!

Medical Supplies

If you find yourself heading to your bunker, chances are that medical attention may be needed due to an injury or wound. Don’t forget that while underground, anything can happen–so make sure you have a robust IFAK kit on hand with loads of extra trauma supplies as well! For top-notch medical kits for all skill levels and needs, MY MEDIC is the ideal vendor; from individual first aid kits (IFAKs) to Trauma First Aid Kits (ITAKs), they have it all.

Gas Masks and Filters

It’s no secret that the primary motivation behind constructing a fallout shelter is to survive a nuclear attack and its ensuing destruction. However, what do you do when an unforeseen event necessitates stepping outside while it’s still perilous? That’s why possessing at least one gas mask plus multiple filters is imperative for everyone in this type of situation. I highly recommend MIRA SAFETY as your go-to vendor for all of your gas mask needs – order some today if you don’t already have any!


Even if you don’t need money while underground, it is essential to have a reliable source of funds once you decide to leave your bunker for supplies or reenter society. Cash is usually the best option but in dire circumstances, gold and silver are dependable backups.


With the potential for spending extended periods of time in your DIY bunker, it’s wise to determine what activities you want available. Of course, tuning into the news via tv and radio is vital; yet keep in mind that these require electricity! Music can also be enjoyable but make sure to consider acoustic instruments like guitar or harmonica as alternatives. For children, store plenty of physical books along with board games and puzzles – a great source of entertainment during long days indoors.
