The confusion lies in the fact that before Auschwitz became an extermination camp it once house Jewish political war prisoners whom were treated well & had spring bunks & ensuite toilets which became living quarters for those assholes (Please click here for more information) running the extermination camp Birkenau I & II.

Above Photo shows the Kanada building during construction (Krema IV in the distance - see more photos in this blog post) at Auschwitz Birkenau II.
Victims were lead into a building and forced to go downstairs into under ground buildings. Zyklon B pellets thrown in behind them, to escape the gas victims fled to the back of the room. This was done over & over, cramming more and more inside the underground chambers until completely filled. Trains packed with passengers simply disappeared into these underground buildings never to be seen again.
