Adhesive for bathroom porcelain floor tiles on wooden floor.

Hi I was wondering if you would be able to recommend a tile adhesive to be used with an uneven wooden floor (varying depth of timber planks). The plumber who installed my bathroom suite set the bath to a height that took into consideration a plywood level of ~6 mm (height is set for the side panel of the bath) plus 10 mm porcelain floor tile and ~3 mm adhesive.

I hope to keep the 'step' into the bathroom as low as possible as however I guess it doesn't matter too much as I can put a sloped piece of wood before the tiles in the bathroom.

So i have looked a couple of sites and as an example Bal Rapidset Flexible requires a plywood depth of 15mm. This would also require the plywood to be primed with Bal Primer 1LTR. Would the plywood still need to be a special type (WBP as metioned here)? Or if the Ply was WBP would it still need the Primer?

Is 15 mm (ply) + 3mm (adhesive) + 10mm (tile) the lowest i can get the 'step' or is there another type of adhesive that will require less height?

And another quick question is if porcelain is a ceramic ... then can I use any adhesive that says 'Ceramic' as long as it does not say 'Not porcelain'?

Thanks in advance

as your floor is boards I would skim with flexi rapid then lay the boards on top to help take out any uneveness in the floor.Once the boards are laid on the adhesive and nice and flat let the adhesive go off for a couple of hours the fix with screws too at 200mm centres.

You'll be fine with 12mm ply. Read the sticky for details.
