Bath Rugby - the 2008 tournament champions - will be the top ranked club in the quarter-finals and will play the fifth best Amlin group winner on the first weekend in April.
The maximum point haul they got from the commanding 53-8 victory over Bucharest Wolves at the Recreation Ground - their fifth five-pointer of the campaign - swept them to a 29 point total and out on their own as the best ranked pool winner, so avoiding any of the three Heineken Cup runners-up qualifying for the knock-out stages.
Full back Jack Cuthbert had the honour of banking the bonus point with his second and Bath's fourth after just 27 minutes, hooker Tom Dunn getting the try scoring underway after 13 minutes before Bath were awarded a penalty try by referee Laurent Cardona.
Horacio Agulla got their fifth after the break and at least the Wolves got some reward with the ball in hand with scrum-half Grigoras Diaconescu going over the home line.
But it was pretty quickly back to business for Bath as Nick Koster and Chris Cook crossed before Cuthbert completed his hat-trick with Bath's eighth amid the inevitable rush of replacements.
There was still time for Will Skuse to take their tournament tally of tries to a hugely impressive 37 in their pursuit of more European glory.
