Wobbly Toilet !

[Monkey Wrench]

I recently installed a new close-coupled toilet which, despite my attempts to prevent it, wobbles. The customer laid a new floor which is not level and the pan has a long narrow base.
When I installed the toilet I used some plastic shims to stop the pan wobbling, secured it to the floor with screws and then siliconed around the base of the pan which is all that is normally required.

However, the customer called a few days later to advise that the toilet was wobbling so I have been back and, despite spending over an hour using different thicknesses of shims, there was nothing I could do to stop it wobbling.
The pan sits flat on the right hand side and the back but there is about a 6mm gap at the front which gradually reduces to nothing towards the back left side of the pan.

Has anyone please got any suggestions as, something that is normally so simple to resolve, is giving me a lot of grief.

Thank you.

Big can of expanding foam! Are they letting the silicone go off before sitting on it? Are they slightly larger individuals??

Bed it on grout, or rapid setting tile adhesive

Thank you for the posts.

Yes, they did give plenty of time for the silicone to go off and no, they're no large at all.

I had thought of using tile adhesive but, as the rim of the base is only about 12mm thick, wasn't sure how it would work. Obviously I wouldn't need a bed of tile adhesive over the whole base area of the pan but only the rim that touches the floor. Would I use a combination of shims and tiles adhesive or just adhesive ?

Thanks again.

Hi Mr. Wrench

What type of floor is it sitting on?

Tiles or vynil or vinyl (whats the correct spelling?)

BTW

I would hate to be the fitter who came round to the customers house to do some repair work (change/re-set a leaking pan connector for instance) and had to inform the customer that the only way i could remove the pan would be by destroying it because it had been set onto a bed of tile adhesive, foam etc.........

there must be a better way and I was just approaching it from a different direction of making good the floor first.

Or just to ask a silly question, and Im sure you have but has the pan been inspected for deformities on the base?

Sorry for my ignorance but what on earth is pug ?

Use shims and tile adhesive

Thanks for that. The flooring seems to be plastic (not vinyl), would tile adhesive still work ?

The flooring is a kind of plastic material and definitely not vinyl (see pic).

That's a good point iiplumbing, once its installed with tile adhesive it's certainly not going to move but, without smashing the pan, there's no way it's going to come out either.

To be honest, I haven't checked the pan for deformities (which perhaps I should) as the customer bought the fittings over six months ago so they can no longer be returned.
