But suffered a fourth consecutive defeat at the hands of an impressive wasps side. A Dave Walder penalty and Tom Varndell try gave Wasps a deserved half-time lead as the hosts looked lacklustre.
Olly Barkley was on target with two penalty attempts after the break but Walder’s boot ensured Wasps’ victory.
A second successive home defeat for Bath means they could slip to ninth in the Premiership table if Harlequins beat winless Leeds on Sunday.
Wasps began with some stout defending in the opening quarter but Bath lacked the precision to get on the scoreboard.
Richard Haughton and Walder threatened the Bath line but both were denied by outside centre Jack Cuthbert before an infringement in front of the hosts’ posts allowed the Wasps fly-half to open the scoring.
It was Walder’s deft chip over the top that Varndell gathered to score on 33 minutes but his conversion drifted wide.
