Harlequins regained the top spot in the Aviva Premiership less than 24 hours after being deposed by reigning champions Saracens thanks to a 14-6 win over Bath.
Their six-month tenure at the head of the table was briefly interrupted when Sarries won 45-9 at Sale on Friday night.
But, in front of a 13,882 sell-out crowd at the Stoop, three penalties from former New Zealand fly-half Nick Evans and a late try by replacement flanker Maurie Fa'asavalu secured a hard-fought victory.
Fly-half Tom Heathcote replied with two penalties for Bath.
