Sorry I may have not been clear, the leak is due to the gap between the tiles at the bottom of the shower and the shower tray. Water is splashing up and into the gap, or running down the shower walls and into the gap at the bottom. This is causing a leak downstairs. There is no issue with leaking pipes.
