not quite down to water ingress through a well grouted joint is it mate i suspect a larger problem than that and i do think tanking is a good thing as a back up so the background will remain intact in such situations

time to let this go but respect to any tiler that will spend his free time doing test .showing results weather right or wrong we all learn did you know 99.99% of all bathrooms and shower rooms in the uk are untanked .

And 99.9% of failures in them are down to that too!

Yeah fair play for Deano to going well out of his way to prove a point. Not everybody has time for that.

i am sorry having to disagree here having inspected many failed shower and bathrooms .75% bad pluming ie joints behind shower leaking when under pressure bath not silconed to the wall shower tray under plaster board and so on .10% no silcone any were apartanly plummer ment to come back and do it .
15% realy bad tiling very lippy poor grouting allowing water to make very easy in roads.so what do i make of all this .well all you need for a great job is a plummer who knows how to seal his work .and a tiler who double checks .then seals again .tanking is for when you dont trust anyone .not even your self

Swimming pools are rarely tanked. They also rarely fail. The failures you see in showers tend to be a result of what the tiles are stuck to not the fact that the grout allows the passage of moisture. Plywood, plasterboard, mdf etc etc... I also still maintain that whilst grout is not resistant to the passage of moisture more failures occur as a result of poor corners.
