[quote=NETT Darren;21702]The tiles are probably falling off due to poor fixing rather than not doing the tanking, it is recommended for power showers but so is epoxy grout and i bet not many touch that stuff. You can get away without the tanking as said above as long as AA adhesives and grouts are used. It comes down to your sales skills as to weather you can convince the customer to go for it. What you have to do is create a disaster then sell the solution, if you go to topps tiles and get one of there mags, they used to have a picture of the BAL WP1 tanking kit and a picture next to it of a wall that has been subjected to water penertration, show them that and that should convince them a little more to have it done. it will take a while for the walls to get to that state on the picture though[/quote]

With the greatest of respect the tiles are falling off because the plasterboard behind has disintegrated due to water damage. If the plasterboard had been tanked the water wouldn't have been able to destroy it. So perhaps more accurate to say that the wall is falling off rather than the tiles.
