9 bathrooms and 7 showers
Sharing a bathroom with one or two siblings can be difficult enough, but try sharing one with 20 other people. All of the hot water is probably out after the fourth person takes a shower, leaving 80% of the family bathing in freezing water.
We don’t know much about the hot-water situation or whether they believe in it (you’ll find all sorts of weird beliefs in the Duggar household as you read on), but we do know that they have nine bathrooms at home and seven showers. So, maybe tardiness isn’t that huge of a problem for the Duggars.
