Until I was nine, we lived in a trailer in Vermont that 10′ x 57′ (and those are the OUTSIDE dimensions, including the hitch); even THAT place had two bathrooms. A good friend has a one-bathroom house in San Diego where he lives with his wife and two kids; we got to discussing how one bathroom works out with a family of four and he responded with this (and yes, he IS an engineer):
Two kids, my son is almost 8 and my daughter is 5. Tick tock, tick tock, the demand for the bathroom can only increase.
Right now we have a serial process in the morning:
1) My alarm goes, and I snooze in bed
2) My wife gets up and goes to the bathroom
3) My wife wakes up the kids and they each go to the bathroom
4) I wait until I hear the bathroom door open 3 times
5) Kids go and eat breakfast
6) I get up and use the bathroom for my morning ritual, the three S’s
- Shit
- Shower
- Shave
7) I exit the bathroom and eat breakfast
8) The kids take turns getting dressed and using the bathroom to brush their teeth and wash their faces
9) When the kids are done, I use the bathroom to brush my teeth
10) We all put on our shoes and I take them to school
11) My wife has full access to the bathroom
You gotta love that it just works; he should get this and then they can do laundry at the same time:

Ok, I’m the engineer that had the one bathroom house. Here’s my new solution – bought a different house (4 bed / 2 bath), includes a guest house (2 bed / 1 bath), and a bathroom built on the patio so when you go swimming in the pool and need to do your business, you can use the patio bathroom without having to dry off. There, problem solved – family of four and we have a total of four bathrooms. No more waiting around here!
