I would test plumbing first !!!
Then if thier is no dought that it's leaking through the tiles check for movement in the base if all feels solid. I would be very very tempted to remove tiles in the shower base and try and re-tank it with BAL WP1 then if possible I would probably tile with a mosaic to ensure no void's are possible and keep fingers crossd
