Sounds like that's the one to use then, assuming I can get someone to ship it to Dublin, but that's another thread altogether...

Just to be 100% sure I've got it, here's my new list:

1. 18mm WPB ply (not marine ply)
2. 12mm tile backer board (I can only get 12mm rather than 10mm)
2a. Electric underfloor heat mat
2b. Latex
6a. Isomat or similar, taped on seams and at walls
7. Tile adhesive
8. 8mm Slate Floor Tiles
9. Grout
10. Slate Tile sealing solution

Thanks for the extra tips - now you mention it, the sales people did suggest sealing the slates both before and after laying, so I'll do that, and also wash & dry them first.

A couple of other questions while I've your attention too...

What's meant by the latex layer that goes on the UFH? Is this a powdered tile adhesive that's been enriched with a latex solution like this one, or something else?
Everbuild Floor Flex Plus Latex Leveller Liquid 5 Litre - https://www.goodwins.ie/products/everbuild-floor-flex-plus-latex-leveller-liquid-5-litre-0071025.html

Also, I've a couple of options regarding tile backing boards. There seem to be two types - cement boards like Hardibacker or this one here:
Permabase 8x4' 12mm Non Combustible Cement Board - https://www.goodwins.ie/products/permabase-8x4-12mm-non-combustible-cement-board-0023296.html

Or foam based ones like this one:
12mm Tile Backer Board 1.2 x 0.6mtr - https://www.goodwins.ie/products/12mm-tile-backer-board-1-2-x-0-6mtr-0023293.html

I'm guessing I'm better off with a cement board for a floor?

Sorry for all the questions!

Not to confuse matters, but what about your backer board, then vario pro, or ditra heat, joints sealed, wires in then tile, that saves you levelling, saves time, less layers
Other brands are available, from uheat a forum sponsor too, they sell an elektra kit which is very good value

Pointless using hardie & decoupling systems together

A 10mm backerboard will only decouple and won’t give any structural integrity to the floor. It’s simply an water resistent overlay to stop tiles debonding.
Both hardie, and ditra take out any minimal lateral movement. (Movement from left to right) not up and down.

Ditra Matt should allways be laid above the UFH

Easiest solution for wetrooms is a waterproof decoupling mat with tapped joints and paint the walls if desired (I allways do ) manufactures states only the floors need to be tanked.

So you’d only need to do the following

18mm ply wbp
UFH
Screed
Adhesive
Matting
Adhesive
Tiles
Deal

This solution will hardly raise your floor.
