I've double checked in the dealers workshop manual and the illustrated parts catalog (all years) and they only show the one washer fluid bottle mounted behind the left headlight and the fluid pipe to the rear screen passing down the (UK) passenger side comming through the engine bay bulkhead and then down the side trim by the passenger door hinges and then along the sill to the rear. So your wet floor could well be down to a split/damaged pipe, as to cost of fixing that will depend where you take it, dealer man hour rates are silly money!!
