The Potters meet Manchester City in the decider at Wembley Stadium as they strive to lift the famous trophy for the first time in their history.
Pulis said the supporters have been so important in helping the playing group move forward and trusts they will have a great day out tomorrow.
"We have built a community club over the last five and a half years that the supporters have really grasped and taken us forward," Pulis said.
"It has not been the players, it has not been the chairman or coaching staff, it has been the whole community that has done this.
"The FA Cup is about dreams. I have watched City a couple of times and they are a very good side with excellent players. I am sure next year they will move up an extra gear.
"They are an emerging force and we know what sort of task we are facing. But we are determined the players are relaxed and the supporters have a great day."
