A dominant second-half from Bath helped the league leaders to a 43-15 win in front of a sell-out crowd at The Recreation Ground.
The sides traded blows in an entertaining first 40 minutes to go into the break with only four points separating them, 19-15, before the hosts scored 24 unanswered points to register the 28-point victory.
Bath skipper Ben Spencer opened the scoring after only three minutes when the scrum-half spotted a gap in the Tigers defence at a lineout and sniped through to run it in from near halfway.
Handré Pollard cut the deficit to two points, 5-3, with a long-range penalty goal shortly after Spencer's try, before Leicester went down a man with Ollie Chessum shown a yellow card for what was deemed a shoulder to the head.
However, while Chessum watched one, a spectacular finish from Joseph Woodward took Leicester into the lead in the 16th minute.
On the back of the Tigers pack powering up field, Jack van Poortvliet spotted Woodward out wide and kick-passed to the right hand wing where the centre took the ball in a contest and then stepped and stretched out to score. Pollatd's conversion went wide meaning Leicester's lead was only three points, 8-5.
Bath hit back soon after when Beno Obano crashed over and Finn Russell converted to see his side into a 12-8 lead. Chessum returned from the sin bin to make it 15 on 15, which was then back to 14 on 15 when Bath hooker Tom Dunn received a yellow card for head-on-head contact while attempting to make a tackle.
Tigers took advantage of the extra man in attack with some slick hands to the right, deep inside the Bath half, and Freddie Steward sent Adam Radwan over with a perfect last-pass for the speedster. Radwan's try was the ninth for the wing in as many appearances for the club.
Pollard converted to see Leicester lead by three points, 12-15, with five minutes remaining in the first half.
Ill-discipline helped Bath find crucial territory in the final stages of the half and, with only one minute remaining, took back the lead when second rower Quinn Roux burst through to cross. Russell converted the score to see his side take a four-point, 19-15, lead into the break.
It took just seven minutes for Bath to extend the lead when Dunn crossed in the 47th minute, extending the difference to nine points with half an hour remaining.
Both sides trade blows in a tough battle before the home side, with fifteen minutes remaining, scored the first of three late tries to confirm the win. Replacement prop Will Stuart was the first to get over the chalk, which Russell converted.
Joe Cokanasiga, on the end of an intercept and full-length effort, bagged the second, and Will Butt rounded out the win with an 80th minute try, followed by a Russell conversion, to see it finish 43-15.
