Maneuverable Toilet spray pipes like kink free collapsing Garden hoses?
There are bidet toilets that spray (2 positions) heated water, and blow you dry.  It has a heated seat, too boot.

I've installed the Toto brand version (Washlet) (a seat replacement).  It has water and electrical hookups included.  The spray wand self cleans and self stores.   

I can recommend its function and efficacy.
