We have 5 people (soon to be 6) and one bathroom and one toilet but you have to walk through the bathroom to get to the toilet. Luckily only 4 of us are using the toilet right now but DD is showing interest in toilet training so it wont be long. It isn't great. I would love another bathroom but I would love more being able to use any tap in the house without it affecting the temperature of the shower. I cant cook dinner or flush the toilet without burning the tripe out of whoever is showering. We make it work though. Have no choice.
