We only have one bathroom too. Took me awhile to get used to that. The house I grew up in had four! Basically one per floor + my parents

ensuite.

At mum's we have two upstairs and two downstairs. I'm at the bf's just now. A residence should always have more than one!

I agree. What if someone's showering when you need to pee? :/

loo isn't in the shower room, so that's alright
