Hence "some access".

A king 1000 years ago would have no conception of what a shower is. They would take baths, but even then, that'd be a seasonal/yearly thing.

Maybe Incan kings were just not very good. European cities had massive public baths right through the middle ages, "and private domestic baths... were hardly unknown to the Romans". https://books.google.com/books?id=KKrhJ9BbMkkC&lpg=PA63&ots=...
