Silicone strong enough to hold a toilet?

[RoundSquare]

As the subject really? Is silicone on its own strong enough to hold a toilet on top of ceramic tiles plus also siliconed round the rear to the bathroom furniture?

[The Natural Philosopher]

yes.

Well the loo in my workshop is only held down by sanitary silicone, and it's not moved in the last 3 years.

I daresay it's how the user lands that matters.

I put ours in that way - in fact thinking about it - both of them, some 15/20 yrs ago and they've never moved. Rob

Yes - mine is 100% held by silicone.

Way I did it was to clean the floor with alcohol, position the bog, mark round the base (few bits of masking tape or a washable pen), then remove bog.

I applied a bead of decent grade strong silicon then carefully reainstalled the loo but sitting the base on 4 x 2mm packers[1], at each corner.

Wipe off any excess silicone and so not touch for 24 hours.

next day, I removed the packers, trimmed off any excess silicon (trying to undercut as much as possible) then went round the whole joint with a white sanitary silicone to seal and provide a neat finish.

Left that for another 6 hours - then the loo was usable.

The loo will seem "flexible" IME for about a week but will be well bonded. After a week you could not tell it was not bolted down and this it remains.

I have no rear silicon - but I do have a long base.

[1] 2 reasons - the bog had an unven base (my tiles were spirit level perfect in that area) - I did use mostly 2mm and a 3mm packer until the loo was not rocking. The other reason was to ensure that all the base was on a silicone bed rather than some squeezing out and leaving ceramic-ceramic contact which I feared might be a bit "crunchy". Maybe I worried too much, but it worked...

Another advantage is that if you ever change the loo, you do not have damage to the tiles (screw holes) if the new base is different.

I used Evostick Nail & Seal to stick down a pan in the Gents of a rowdy bar 6 mths ago - it hasn't moved since.

[Skipweasel]

No.

My toilet seat has been sitting on the floor for nearly 20 years. I have not got around to fixing it to the floor yet. Nobody has knocked it over so far.

[RoundSquare]

Thanks guys for the feedback. Reason I asked was, I recently had a new bathroom fitted out from a shell which included underfloor heating. I think the builder put the heating mat under the toilet and is now telling me the toilet doesn't need screwed to the floor. However he never put the pan on a bed of silicone but rather put it around the base / floor. To be fair to him it hasn't moved in the last 2 weeks or so since he fitted it but I thought he was BS me re silicone strong enough to hold it.

I would be happier with it on a bed, not just weakly glued around the edge.

However, if it falls off, it will be afailry simple no mess matter to rebed it:

Cheesewire it off (eg piano/guitar string) (if it is still partly stuck).

Razor blade scraper to clean off old silicone.

Good clean of both parts with solvent.

Bed it like I said in an earlier post.

[Skipweasel]

Fair enough. I wouldn't risk it having seen it come unstuck. Admittedly only once but that was the only time I'd seen it done so I steered clear myself.

My toilet seat can't fall over as it is in the world's narrowest toilet room. There's less than 15cm from the seat to the walls oneach side. It can't fall forwards as I've used Jubilee clips on the rubber boot joining the pipes. The plumber installed the sewer pipe a bit high so I either have to lower it or have the seat sitting on spacers. Just another job I've been putting off.

Offset connector?

particularly when women use half a toilet roll of paper to hide the splashing of water which they seem to find embarrassing.
