[fred]

Whar would be te best adhesive to secure a wc to ceramic tiles ?

[Clive Arthur]

Silicone sealant IME.

[John Rumm]

+1

or a modified silane sealant like plumbers gold

[Brian Gaff]

I was going to observe that mine is screwed down to the floor so if there was no give in the seal it would crack when you sat on it and the wooden floor moved!

Sit it on a nice thick bed of good-quality silicone and prettify the edges with a Fugenboy

[Fredxx]

After refitting a washbasin to the wall because it was attached with silicone and the plaster skim failed, I can't recommend the practice.

I would screw the WC to the floor and to the wall.

[The Natural Philosopher]

Yes, if its a tiled floor. Prop it up on matchsticks to get a gap, inject silicone under it, when set remove matchsticks and finish the job. 23 years and going strong here

Do you mean actually fixing the WC or just sealing any potential gaps?

If the former perhaps there isn't an adhesive and you need to screw it through the tiles into something more substantial. The weak point is likely to be the adhesive or the bond between the tile and the wall.

With a WC someone sitting awkwardly on the seat could put a large sideway force on your glue join or if someone is feeling "ill" they may lean heavily on a close coupled cistern.

Long term even a repeated slight movement could result in a water leak from the connection into the cristern or a leak from the toilet outlet.

Tip when assembling a close coupled toilet smear some grease around the fixings screws . You will thank yourself 10 years down line when you have to remove them for some maintenance.

Earlier this year I spent a wonderful hour in the most awkward of positions with a junior hacksaw blade with the end wrapped with insulating tape dismantling a friends toilet :)

four brass screws are required by thr Burgh Police scotland act

[alan_m]

Just make sure that the are not just brass coloured :) I once fitted a tap with what looked like a brass back-nut. Years down-line the tap became loose as the back-nut had complete rusted :(

These days probably better to use marine grade stainless steel.

[jim.gm4dhj]

states Brass only

They were often grouted in the past. There's not normally much flex in the small area that the toilet is sitting on. The movement is generally over a larger area and the flexible seal to the soil pipe allows for that.

[SteveW]

Can they really refuse CE marked toilets from their beloved EU, which only have two stailess-steel fixing screws?

[Davey]

I bought my Dremel for that job.

[SH]

A multitool is even better for this job......

[jim.gm4dhj]

should do....no standards any longer...you get people wanting to glue cludgies down ....

[alan_m]

I would liked to have seen you make space for a multi-tool or even found a Dremel blade/disk of sufficient size to reach in far enough to cut the head off a bolt.

Unfortunately this was replacement flush mechanism requiring the cristern to be removed from the pan and every component holding the two together was a mass of rust. It was also the blind type of fixing where the head of the bolts are between the pan and cristern. The only access to the gap between the two was from the back under the cristern. Luckily, and with a great deal of swearing, one side could be undone to give a bit free play to open up the gap.

If it had been a replacement toilet the ideal tool would have been a lump hammer :)

[SteveW]

I thought that part of the trade deal was that CE marked goods were automatically considered acceptable?

[fred]

Yes I could screw it down but access to the fixing holes is restricted by the bowl and I'm fearsome of cracking the bloody tiles. At present it doesn't sit flat so I inserted a shim as a temporary measure.

We have friends who borrowed a house while they moved. The husband was sitting on the loo the first day and called down to his wife in much fear. He felt his head was spinning and he was losing his balance. Hus wife had a great laugh when she pointd out to him the bowl was rocking.

We once rented a house where the toilet had a wooden seat. This seat was cracked across the front. This crack opened up when one sat on the seat and was strategically placed to seize your goolies when you stood up. Very painful but not a lesson forgotten

indeed...bring back Brittish Standards
