We had indoor plumbing but I remember one of my friends had 8 kids in their family and a out house... tub in the kitchen, bucket of water on the table with one dipper for all.... One summer their dad and uncles built a room addition. This was totally cool. It had a door from the out side with a sink and a hose with a floor drain just inside the door, 2 potty stalls for privacy, a shower, a tub, 2 more sinks and an awesome big mirror - oh and it had a door from inside the house too.
