New subfloor over wet UFH

[Nic_P74]

Hi all,
Been a while. Need to quote for complete bath room.
The exisiting tiles finish pretty much level with the carpet in the bedroom. So not sure what the subfloor is under the tiles. I know it is chipboars on battens in other areas of the upstairs. (Guessing not chipboard in bathroom or would have expected tiles to pop with ufh. )Was there when customer moved in, so they dont know and didn't want to start pulling things apart.
Best/product system to go straight onto battens and keep floor level to a minimum?
Tia

I would of thought best thing for heat transfer If your replacing existing is gifa floor if you're overboarding it would be Hardie backer .

Unfortunately, I wasn't really able to see what type. Don't think I will know until I pull up the old tiles. The subfloor will need to come up in places for new bath position. I'm just looking to give them a price for worst case scenario of replaxing whole subfloor. Hopefully with better heat trabsference as they said it never gets that warm. Cheers

We can advise you but we will need to know what you have to work with? I can't see that you can quote accurately without knowing the make up of the floor other than price to replace it all . Kop

Yes but how people say just come and do it don't worry about the money . All my customers get a quote but I also state any extra remedial work that is needed will have to be requoted for . They need a ball park otherwise they could be thousands apart.

That is what I am trying to do. Give a best case and worst case scenario with the caveat that until the floor is pulled up it is just an estimate.
I also always look to do the best job possible with the most suitable materials (as I'm sure everybody here does) it was put in 12 years ago and products have developed that are far more efficient and better performing.
I have seen the GIFa, brio,fernacell etc. All the research or spiel is never as good as somebody saying. " I've used this product, easy to work with and I stall and good perdomance "
Appreciate all your input
