We have a leak with water dripping into hall ceiling below from our shower. We had the shower tray tiles and surround replaced thinking that was the problem but not the shower ( running from mains) itself. Everything was OK for eight weeks but then the shower has just started leaking again, with water appearing in exactly the smae place as before. ANy ideas?

Somehow you have to get access to the shower base where the waste water drain is - chances are there's a leak on the bottle trap or one of the joints. However if all seems well here you need to check the joints between the wall and the shower base, looking for any tiny gaps in the tile grout or sealant.
