Sam Underhill and Zach Mercer got the visitors off to the perfect start inside 15 minutes, and following Trevor Davison’s score for Newcastle, Tom Dunn grabbed the first of his two-match tries.
Tom Penny brought Falcons back to within seven ahead of an authoritative second-half Bath performance.
First, prop Henry Thomas burrowed home for the all-important bonus point score before Dunn and Jack Walker completed a scintillating 80 minutes.
Falcons were awarded a late penalty try for their efforts on a day where Bath were ruthless from minute one.
Joe Cokanasiga stopped the home side attacking early on down the left, and as he has done so often for club and country, Underhill swooped straight in on the ball to win a penalty.
The England flanker’s hard work led to Stuart Hooper’s men moving up the field at a rampant pace, and a strong driving maul saw him dive over for the game’s opening try.
Foot on the peddle and one to 15 contributing in all aspects of the game, Bath didn’t let off and motored forward against the wind. The fleetfooted Tom de Glanville showing pizazz on his way to a half-century of metres gained in the first period.
While he danced the team on, the forwards hammered the Newcastle fringes, breaking them down with every pick until the unyielding pressure told and Mercer brushed the whitewash.
Falcons responded with ferocity and prop Davison squeezed under the sticks to their credit, though it proved to be their only moment of joy in the first 30 minutes as Bath regrouped and went again as one.
Controlling the match’s pace with patience and confidence, Bath continued to build and build to the point Newcastle struggled to cope with their intensity, and hooker Dunn proved the beneficiary.
Newcastle had their moments; Mateo Carreras proved a nuisance on the run, which presented the opportunity for full-back Penny to finish.
At 19-12, the scoreline could have gone in any direction, but the Blue, Black, and White ensured it went theirs with a strong show of unity and grit.
