Hi All
I am fitting a shower at the weekend in a new bathroom. There is a shower tray and one side the wall is an external plastered/ rendered and the other is a stud wall with hardieback boards on it. Both walls will be tiled.
When we have done this before I have masticed the tray to the wall, sealed it from above and then tiles on top and finally sealing the gap between the tiles and the tray. For the tiling used waterproof adhesive and grout.
Someone has told us we should really "tank" it but TBH not sure what this means in this context and indeed whether this is needed / better than my usual approach.
Thought I would ask the collective here for their views.
Thanks
Lee.
