Rowett guided Albion to fourth in npower League Two this campaign, the club's highest finish in the Football League.
He saw his team win the first leg of their play-off semi-final with Bradford 3-2 at Valley Parade but a trip to Wembley in the final eluded Burton as the Bantams won 3-1 at the Pirelli Stadium to take the tie 5-4 on aggregate.
Rowett, 39, had already started preparing for next season and insists his plans are not significantly changed by the fact his side will be remaining in League Two.
"I genuinely think that we can produce a better side next season," said Rowett.
"I think that we've learned a lot this season, although there are still one or two things we'd like to do better.
"We weren't going to spend stupid money to stay in League One, so we're still looking at players who will either get us into League One or keep us in League One - it's no different.
"It will be players like Robbie Weir and Damien McCrory, who have hunger and drive.
"There will be some changes again. We've already looked at it and there needs to be some. But what we have is a real core, a nucleus who will be here next season."
