Answer: Yes and No. Dunk tanks are designed to be set up outdoors. A water source and hose will need to reach the tank to fill. The dunk tank then has to be drained. While using a dunk tank, water will splash out. Your indoor facility would have to have drains on the floor to capture the water as it is drained from the tank. You would also need at least a 6ft opening to get the dunk tank into the facility.
