Why in the Khrushchev set a window in the bathroom?

The houses, which were built during the reign of Nikita Khrushchev was much unexplained. For example, those who live in Khrushchev knew that it was found a window that looked out on the standard of the kitchen in the bathroom. Why this was done, many are not even aware.

On this topic, there are many different opinions and hypotheses. Somebody says that these windows are installed to save energy. That is, the light fell into the bath from the kitchen. This view is probably mistaken, because the window size and the amount of light it is not enough for full illumination.

The following hypothesis is based on the fact that the supporting wall that separates the wall from the bath is protected from the blast that might occur from leakage and gas detonation. In this case means that the wave knocks out the window and rush to the bathroom, directing most of its energy is there, the bearing wall supposedly remain in place.

This hypothesis is also lime, as the explosion of domestic gas allocated a lot of heat, which is capable at all times to destroy everything in a radius of 5-10 meters and the window will not be able to save situation.

Everything is much easier than many assume. A friend of mine told me that his grandfather had just been designing Khrushchev apartments. He told that the bathroom window was provided for those who suffer from claustrophobia (fear of enclosed spaces). While the first thought about the people and their comfort than about financial gain.
