I have had to get the old plasterboard behind the shower ripped out and start again due to leaks coming from the shower onto the tiles and going behind to the flat below.
The builder who is re-doing it is tiling tiles onto wood board (see photos) and not Hardie board or similar. He has left me in the lurch over the weekend and now I am trying to find out if what he is doing is correct to prevent leaks in the future as my understanding was that tiles should get tiled onto Hardie board to make sure it's absolutely water tight?
He has the Hardie board downstairs which hasn't been used. Behind the shower are the pipes and then stud panels. So would the Hardie board normally be attached to the stud panels?
Sorry if this seems obvious but I am a newbie to this and keen to make absolutely sure of no leaks in the future.
Thanks
