Underground Bunker Prices

A 200-square-foot bunker costs $52,750 on average, for just the bunker itself. Most bunkers of this size range from $37,000 to $65,500. Smaller bunkers may only cost around $19,000 but you could easily spend upwards of $8 million for a large underground shelter.

While these prices are for kits that typically include water and air filtration, they often won’t cover delivery fees nor installation. Shipping alone can cost around $10,000. Excavating the land and installing the bunker could cost anywhere from $20,000 to $25,000. Your most affordable option for installation might be putting in a bunker during construction on a new house.

A 200-square-foot fallout shelter costs $52,750 on average. Nuclear fallout shelters became popular during the Cold War. Nowadays, nearly every bunker or bomb shelter comes fully equipped with water and air filtration to protect against radiation exposure.

Prefab Nuclear Bomb Shelter Price

Prefabricated nuclear bomb shelters span from $40,000 to $80,000 (not including labor and shipping costs). It’s common for manufacturers to offer prefab bunkers or shelters and then either construct them onsite or ship you the materials.

Doomsday Bunker Cost

A doomsday or apocalypse bunker can cost anywhere from $35,000 to several million dollars. Some companies use “doomsday” bunkers interchangeably with nuclear or fallout bunkers but some people see these types of bunkers as different.

A bomb shelter is sometimes seen as a temporary place of safety whereas a doomsday bunker is sometimes considered to be a long-term housing solution. As such, doomsday bunkers might cost millions and include things like a hydroponic gardening system, greenhouse, or even a movie theater or pool.

Above Ground vs. Underground Bunker Cost

An above-ground shelter typically costs less than one that’s underground, both in materials and labor. For reference, the average cost to build a storm shelter ranges from $3,000 to $15,000 above ground and $4,000 to $30,000 below ground. Talk to an architect near you for an estimate.

DIY Bomb Shelter vs. Hire a Professional

Building an underground bomb shelter is a ton of work and requires professionals with engineering and architectural backgrounds. Trying to tackle this project on your own is extremely risky and could even be illegal if not built to code.

Hiring an architect costs $5,300 on average but it’s a price well worth your safety. When building something to protect you and your loved ones, the last thing you want is to cut corners.
