Wasps wing Edd Thrower scored four tries as his side bounced back from last week's defeat to Sale with a comfortable bonus-point win over Bath.
The home side, inspired by Simon Amor, never looked back after Fraser Waters opened the scoring on 13 minutes.
Thrower scored two tries either side of the break while Mark Van Gisbergen and prospect Danny Cipriani also crossed.
Bath scored two tries late on through James Scaysbrook and Michael Stephenson but it was not enough.
It was an impressive display from Thrower, who was only in the side because Paul Sackey was on international duty with England.
Wasps' scoring fest started with fly-half Alex King and number eight Joe Worsley setting up Waters.
And Thrower went over for his first five minutes later after some good work from lively centre Ayoola Erinle.
He added a third after Eliota Fuimaono made a hash of a drop out before completing his hat-trick in the 50th minute with another simple run-in after Amor burst 60 metres.
Scaysbrook did cross for Bath after powering over in the 68th minute and three minutes later the visitors introduced former Great Britain rugby league star Chev Walker from the bench.
However the convert's first touch of the ball was a knock-on and he had little chance to impress.
Cipriani marked his first-team debut with a 75m-interception try before Stephenson and Thrower completed the scoring.
Wasps director of rugby Ian McGeechan:
"The way we defended in the first 10 minutes set us into the game and the first opportunity we got, we scored.
"Seven tries and we worked for all of them. When we got the opportunities we took them.
"(Scrum-half) Simon Amor was instrumental in the way we played today. It just shows what a good competitor he is."
Acting Bath head coach Steve Meehan:
"The players are upset with this.
"Those missed tackles against such a dangerous side just kill you and if you don't kick well, sides will just counter-attack you."
