I think I have made a bad choice of accessory!
With SWMBO I bought a towel rail and toilet roll holder. The toilet roll holder needs to have a small spigot screwed to the wall with two screws at approx 9/16 centres. The chrome holder then fits to theis spigot. Two screws are needed to resist the holder from twisting.
The trouble is that the wall is dab n dob plasterboard. I am thinking that I am going to get into difficulties trying to get a good fixing. Going into the breeze block is possible but as yet I am not sure how far back it is. Even then I need to prevent the plasterboard pulling in and making the fitting loose.
Any ideas? I want a neat job.
