And Stephenson admits Warriors must focus on their own game when they run out in front of the Bath crowd.
He said: "Getting three wins at Kingsholm was amazing and we want to take that performance down to the Rec for the final.
"We can't wait for it to begin now. We've showed what we are capable of and if we can raise the level again, we can surprise a few people in Bath."
Stephenson joined Warriors from Bedford Blues this summer and has settled in well to life at Sixways.
After scoring two tries against Gloucester Rugby last Thursday, the young wing says he is aiming for more.
He added: "It felt really good to pull on the Warriors shirt for the first time. It felt good to score. I would have liked to get more but I'll be aiming to do that on Friday.
"Sevens is intense and you have to be really fit. The competition is so good and even though there's only seven players on the pitch you still feel like you're being closed down quickly.
"We've been working hard in pre-season and it paid off at Kingsholm so we're all focused on doing well in the final."
