Fitting a new Toliet Pan & Cistern

[DavePrior]

Hiya.
Fitting a new bathroom suite, I find that the closely-coupled toilet cistern is free-standing, in that it fastens to the pan (to support the weight) but there are no holes in the back to fix it to the wall. It's supported well enough, but the problem is that it is "springy", and not a quality job.
Question (potentially dumb): Can I drill holes in the cistern, to enable me to fix it to the wall. This is for steadying purposes, and not for load-bearing.
Thanks in advance !

Have you thought about contacting the cistern manufacturer and asking them?

I agree with Peter here. Whilst a set of ceramic drill bits is pretty cheap and would probably do the job perfectly well there is a chance you could crack the cistern.

I have the problem that my new toilet does have wall- mounting holes in the cistern but it came with no screws so I am not sure if I should be using specialist screws, especially with the damp conditions inside a cistern.

Have two close-coupled toilets, both with no fixing holes on cistern. Some movement with cistern was eliminated once they were tight against wall.

Thought about drilling, was advised not to by supplier.

As for fixing ones with holes, S/Steel or Brass screws with a plastic screw cup works.

Can you not make a bracket on the back of the cistern lip onto the wall?

you can use a basin mounting bracket. Lip it over the top where it dips in the middle

or a few dabs of sealant usually does the job for me

Thanks guys, I'll have a chat with the manufacturers (B&Q). If they advise not ,I'll try the sealant and/or bracket.

Appreciate your help - thanks again

genuine silicone sealnt sticks like (insert your phrase here) it is also used to hold aquariums together, so it must be good, as for asking at b & q , not too sure about that one

Agree with Breezer. I have recently fitted a "Roca" toilet and it too had no 'oles for fitting the cistern to the wall. Dealer said that was the design, and if I tried and failed to drill it, it would not be covered under any warranty.
When coupled to the pan, there was a degree of movement between the two, but once connected up and positioned within a couple of mm of the wall - I injected 2 clear silicone beads and after a day or so, they are rock solid.

One can even lean back in comfort when reading the paper and there is no appreciable movement!

Dont over do the silicon! you may need to get it off the wall one day. Try and keep it near the top, so you can get a knife down there and cut the silicon away.
