Waterman justified her selection with two tries
Saracens full-back Charlotte Barras, Clifton wing Danielle Waterman and Worcester wing Katherine Merchant all claimed braces of tries in Rome.
Rochelle Clark, Maggie Alphonsi, Michaela Staniford, Jane Leonard and Jo McGilchrist also went over.
Alice Richardson and Katy McLean, kicked eight conversions and 16 points for England's second successive win.
England head coach Gary Street said: "This is a really pleasing performance that saw several flashes of excellent play.

"Again, we made some errors which we must improve on but after a closely fought game against the Italian a year ago I am really pleased with this result."
