Harry Potter and the Chamber of Secrets : Wizard plumbing

Wizard plumbing

So did they have plumbing before it was actually invented? If so, did they just use chamber pots like everyone else and just magic it away? Lastly, if they just magicked it away wouldn't that be more efficient than plumbing?
I don't know why I thought of this, but alas, I did.

lol interesting though for sure. I didn't think about it.
