The first toilet had a wooden seat (splinters?!)
The Romans actually built "hot tubs" in 50 A.D. The Roman Emperor Caracalla had a "bath" that covered 28 acres. Imagine the hot tub parties at that dudes house!
There is a debate as to who invented the modern flush toilet. Some give credit to Thomas Crapper (wonder why?), an English sanitary engineer.
The first hotel to install indoor plumbing was the Tremont Hotel in Boston in 1829. My guess is their rates were very high but very worth it.
We hope this partially satisfies those of you who were craving some plumbing history (you know who you are).
