I recently watched The Family the 1970s documentary about a family from Reading, UK. It’s on YouTube. I found it fascinating both for the time period comparing it to today and just seeing how other people live. I remember them filming a lot of scenes in the kitchen and sometimes they would be sitting on a table that was in a space between the sink and another part of the kitchen. Turns out that table was actually the top for a hidden bathtub, in the kitchen! That honestly blew my mind when I saw that. I never realized it was a bathtub until one of the family members said “can everyone please get out of the kitchen. I’d like to take a bath”
She then lifted up the worktop part to reveal a whole bathtub
