In October 2023, flood water from Storm Babet reached nearly 3ft (90cm) in the dance studio.
It took weeks for the building to dry out and Ms Egan relied on the help of dozens of volunteers to clean up after the water subsided.
She said although the building was now “dry and safe”, she has had to make expensive investments.
“We have dehumidifiers continuing to dry the building to stop further mould and a brand new dance floor so if we flood again we can take it up, drain the water away and put it down again.”
Although Jack’s Theatre School has now fully reopened for classes, many local residents in Catcliffe are still waiting to return to their homes.
Students from the school are taking part in a Coming Home Concert at the Catcliffe Memorial Hall on Saturday.
Money raised from the concert will go to households affected by the flooding.
Ms Egan said: “The floods have devastated this community, we just want to help in any way we can.”
