There are many kinds. Concrete and steel were once used, and perhaps a layer of lead to give added protection from nuclear bomb radiation. Newer shelters incorporate synthetic materials not available in the 40's and 50's. Prefabricated bomb/tornado shelters are for sale, and plans are available to build your own if you want. Some are sophisticated with electricity and water, but a ventilation system is absolutely necessary for all of them so the survivors can breathe.
In the 1960's bomb shelters were built in people's back yard and under houses. It was a very popular thing to do. We were all sure that at some point there would be a nuclear war between us and Russia. Cities designated subways and other places as bomb shelters. Had a nuclear war broken out all of us would have been cinders before we could get to a shelter.
There were various types of shelters during World War 2 in the UK. Individual people might have had a re-enforced concrete shelter if they could afford it. Others (Anderson Shelters), were made of corrugated iron and designed to be self built and placed half buried in back gardens. People who didn't have any outside space were issued with a Morrison Shelter, which was basically a steel cage to be built indoors.
Hundreds of thousands of Londoners used the bomb shelters and survived the Blitz.

In the US, bomb shelters were a boom in business in the late 1950's and early 1960's; the Eisenhower/Kennedy years. They were hardly spoken of after the mid 1960's. By the late 1960's people often spoke fun of those people (made fun of them) that built those bomb shelters. ALthough no doubt some may still exist, bomb shelters in the US are a thing of the past which ended in the 1960's.
Bomb shelters are structures build of reinforced concrete. The outer walls are usually several meters thick, which makes them really hard to break (that lead to the development of a bunker buster bomb). In addition to that, most bomb shelters are under ground. The combination of all the three measures makes the probability of the personnel survival very high.

The Cold War and nuclear arms races in the late forties through the eighties was the impetus of Americans building bomb shelters. They were convinced Russia would bomb America and they could have if Kennedy had not stopped Fidel Castro and the Russians from sending over their nuclear missiles located ninety miles from the US. Most of the bomb shelters were a joke. They never could have protected the people from the radiation in the air or from the bomb explosion.
Great Britain definitely had bomb shelters for not only the general populace but also the government during the Blitz.
