Thorne had twice taken the lead with early penalties by stand-off Tom Holt, and Wath led only 10-9 at half-time through unconverted tries by No 8 Matthew Burrows and winger Dale Jackson.
Centre Steve Mason, scrum-half Joe Bartlett and second-row Simon Butterworth scored for Wath in the second half, two converted by Burrows, to Thorne's tries by hooker Scott Berry and Holt.
