Toby Booth admitted his battered and bruised London Irish team "did not come up with enough answers" after they suffered their heaviest Premiership defeat for more than five years.
Irish had no answer to a fired-up Bath side, crashing 30-3 in heavy underfoot conditions at the Recreation Ground and dropping out of the title play-off zone as a result. Bath claimed a first Premiership victory for two months, having last won in the league when they edged past Irish 13-12 on October 29.
Head coach Booth said: "We didn't come up with enough answers, and quite often we gave away too many gifts. When you have got a side that is desperate to get on the winning trail, like Bath were, and the conditions being like they were, it made it very difficult."
He added: "We put ourselves under unnecessary pressure, and that is really disappointing.
"This is the most competitive league going, we all know that, but the good thing is you get a chance to put it right straight away.
"We have Sale next, and we are going to need to show our character and bounce back. We will find a lot out about ourselves this week."
Bath fly-half Stephen Donald kicked 15 points, but it was the form of England full-back candidate Nick Abendanon and a powerful Bath scrum that proved the most telling factors.
"There are a lot of good players in the Premiership. Ben Foden has got the (England full-back) shirt, and Mike Brown is playing well at Harlequins," Bath rugby director Sir Ian McGeechan said.
"If Nick keeps playing like that, they have got to be in the equation because these fellows can change games. If you have that sort of player knocking on the door for an international jersey, your international set-up is in pretty good shape.
"I thought the attitude of the players right through the 80 minutes was spot-on. We put a good game together."
