Fixing toilet to tiled floor with underfloor heating

[Harvest Fields]

I posted this on purpose to see people’s responses. I know exactly what I would do (I posted it 2 posts down from this one) but there is another post on here still ongoing at the moment that is very similar to this one and the engineer and customer are debating it. Non of the professional engineers that commented on the other post have mentioned any of the ideas here. Just wanted to see how people would react

Old school it cement pan down ?

I will admit on some toilet pans I have solely fixed them to floor using silicone.
I sometimes won’t drill floor when pipes could be below.
Yes, if the pan ever came loose, then I could be accused of incorrectly installing it.
But on large pans on top of clean flat tiles and cistern screwed to wall, they are often very stable without any floor fixing, so silicone added will be very strong. In fact it is very difficult to remove.
Toilet pans are a big footprint so would be hard to pull loose if siliconed.
A basin will glue solid to a tiled wall if silicone used, so same on floor, but perhaps silicone might not grab to some types of tiles.

Every toilet I fit gets a silicone bead ran around the base.

Otherwise when us laddies miss it doesn't run under the pan edge and start stinking of pi$$

You could switch on UFH and use your elbow, it's quite sensitive.. or is that for babies' baths?

That method is flawed, heat spreads.....

In a ideal world it would be fixed via the L brackets but why take the risk if there is a underfloor heating loop there I could fit the pan securely without screwing down and have no problems, hit a pipe and its a hole different story i have respect for the other guys views but we all have our ways of working. cheers kop

Wouldn’t be any risk with thermal camera mate. You should be able to see where they run. In my opinion obviously

I have to fix a new toilet to my daughter's downstairs toilet.She has just had the floor retiled. The house has piped underfloor heating. I am just a bit concerned about screwing the pan to the floor and whether the pipes will be far enough down not to worry. The previous wc was plugged and screwed down in the normal way.Any thoughts please.

Go to Toolstation and buy a tube of Stixall. As others have said fix it back to the wall with screws and plugs and set pan down on a bead of Stixall. It WONT move after 24 hrs.

Or come off in the future.

Side fixing toilet , block of hardwood stuck to the floor with sticks-like ****, screw into hard wood,

FLIR one plugs into your phone. As previous posts if it’s level and there’s no rock mastic seal will do the job. I’d use clear above white

Cheers for the confirmation. Got a link for your one? Would like a look.

As others have said, screw cistern to wall and silicon the base.
