Those who don’t want a second bathroom should do it that way. But what always makes my neck hairs stand on end is the argument "we didn’t have that in the past either." There were plenty of things we didn’t have back then.
My mother talks about times when there was no anesthesia at the dentist, we didn’t have that (it worked anyway, but I’m really glad it’s no longer like that).
My grandmother still had the bathtub in the kitchen (because that was the only water connection); my father also grew up there and the whole family got clean (here too, I’m glad about the change over time!).
In the first apartment of my parents, there was no central heating; they heated first with coal, then with oil stoves (which had to be refilled individually with oil).
The bathrooms in the past were small and dark, but it worked, people got clean too.
Long ago we lived in caves, wore loincloths, and hunted mammoths, right? Many survived that way and reproduced because otherwise, we wouldn’t be here today.
But here we are. Today. In the now. And we have gone through a certain development. Great. We are no longer the post-war generation and we have also stopped only cleaning ourselves thoroughly on Saturdays, in such a way that first the father was allowed into the bathroom, then the mother, and then the children. At least then the bathtub filling was worth it!!
It’s okay if you don’t want an extra bathroom for the children, but please just say so without pointing out that it wasn’t needed in the past either.
Oh, by the way. There was no internet and no forums in the past either. Nevertheless, houses were built.
Some of those houses are still standing today!
Still: I am glad for this forum and have already been able to get a lot of inspiration here.
Let’s be glad that we live today and can afford a very comfortable standard of living!
