Well, you could write about the Hufflepuff locker room being a place of great unity. For example, during a difficult time for the school, the Hufflepuff students gather in the locker room to plan how they can contribute to the safety and well - being of Hogwarts. They might be sharing their unique skills and coming up with creative solutions.
One idea could be a story about the Gryffindor Quidditch team in the locker room before a big match.

Another could be a story of a new student accidentally stumbling into the Slytherin locker room and the reactions of the Slytherin students.
One interesting 'Harry Potter Locker Room' fanfiction could be about the characters having a secret meeting in the locker room to plan a big prank on the Slytherins. It might involve all the Gryffindors coming together, with Harry leading the way, and they use the locker room as their base of operations because it's a place where they can be somewhat private.

They could talk about their recent battles with monsters and how it affects their confidence in normal activities like sports.

First, decide which house's locker room you want to set your story in.
