What I have done before when drilling tiles is form a circle out of blu-tack a bit bigger than the hole and pour some water in it

Thinking about it, it wasn’t tiles it was glass I was drilling

Thin porcelain behaves no different to glass in actual fact, a lot of the original tooling was derived from the glass industry, and we still use it now.
It’s just major brands make us believe we need their kit instead now

Yes I’ll tape joint Jerry, but look at it this way, you have two bloody great 10 inch bolts pulling the toilet and ply on to a frame, with just enough ply sticking out to sit on metal frame. Exactly where is it going to go? Drilled holes have a much higher chance of success than a sodding great hole with a pan stuck to it.
The point of it is that the ply will not crush at all, where’s as the same cant be said for backer boards can it. (Obviously depending two things, how accurately the plumber has secured the pan, and secondly, who exactly is going to be putting their full body weight on the pan. If the substrate flexes, so will the tile. And if anything does develop a leak, it’ll be behind the boarding anyway no matter what it’s made of.

What do you use to match the thickness of the ply as far as i am aware tbb doesnt come in 18 mm or am i missing something .

All I’m going to do is but a bead of CT1 on all the framework for the ply to build it out 1mm then screws when dry. Then use 19mm kerdi board around it.

Are we gonna get into a fight over 1mm thicker Kerdi board Jerry?
Plasterboard is the same.
Others are 20mm.
2mm is not that much of a stretch is it?
It’s typically PB that surrounds it anyway mae.

or you can just skim out the ply with 1mm of adhesive day before fixing.

Or..... if you’re doing floors then you’ll need a 1mm antifracture mat anyway.
Stick a piece of that over the ply.
You can’t use Ditra, don’t know if you’ve even mentioned floors. Sorry can’t remember, ain’t got time to read back atm.

Firstly we are not going to get in a fight for two reasons
1 im a nine stone weakling and easily intimidated.
And
2 the first one again.
But on a serious note i am not trying to catch you out or anything like that i ask because i understand that doing these tiles is technically demanding and if im faced with them i want to give myself the best possible chance of success . So sorry if i sound anal sometimes but it has saved me a lot of grief in the past .

Got no problem with questions Jerry, you of all people should know that.
Yes this work is demanding, but personally I feel the main reason that it is, is because firstly the tolerances we work to far exceed BS and secondly the job has to be carried out to the letter of the law, otherwise they fail, whereas with regular 10-12mm porc they’re so much more forgiving and ultimately only fail because of incompetence.
There’s no room for incompetence with what I do.
The phrase “it maybe ok” doesn’t exist, it works or it doesn’t.
So you’re right to ask questions, without a doubt, but it’s also your personal experience that gets you thro.
As no one has all the answers yet, just best guesses. the product is still in its infancy.
But where as you can bend rules with regular porc, with this product, you can’t.
And besides, common sense from an installers point of view still goes a long way.
