I visited Dachau 3 times. Twice as a child in the early 70s and once when I was with the US military in 1980. I haven’t been back since. I would bet things have changed. I do agree with you about the showers. There was nothing but basic plumbing in the facility. However, Dachau was a labor camp and not a death camp. People died there from overwork and malnutrition. Because of the close proximity to Munich, they didn’t burn bodies there. I’ve been told that dead bodies were shipped out for mass burial. No one I talked to knows where which has been cause for suspicion. Dachau did not have the high death numbers as other camps, and a German history book published in the late 90s did overstate the numbers there, also raising suspicion. I have never visited Auschwitz because its location was under the control of a communist government the last time I was in Europe. Also, I have never talked with anyone who was imprisoned there, so I will not offer any facts or opinions on that location. However, labor and concentration camps were real. Charlie Chaplin depicted one in The Great Dictator which was released in 1940. Also, many US and international media groups wrote about these before the start of hostilities on 9/1/39. Finally, I am aware that the occupying forces kept the camps going after the war for some time. That has even been posted here.
