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.

Perhaps, and this is very tentative, you could drill a single large hole
right through the plasterboard and well into the block. The hole size
can be the maximum that will be hidden by the fitting, I'm guessing
25mm. Then bond with epoxy something that will take the stresses into
said hole. Drill the something to take the screws, possibly before
epoxying in. The "Something" could be a hardwood dowel, or even a length
of steel or ally round if you can drill and tap it.

All my other thoughts involve divorce. It's a lot of trouble for a
