Threshold strip advice. - Tile Advice

[Whitey]

Just wondering if someone could answer this for me please?

Having just had a minor leak in the family bathroom (no pun intended!!) I've scrapped the carpet in order to tile the floor.
The substrate is interlocking chipboard sheets, 18mm i think. Can i prep the existing floor with a primer? or do i have to overboard with something like 6mm cement boards?

Anyway my original question was if I overboard do tile to carpet threshold strips allow for the extra depth of overboard/adhesive/tile??

Apologies if this is a bit of a daft question (its amazing what you start thinking about when the mrs has the tv remote!!!)

A 'Z' bar will accommodate any height transition. The difference won't be as much as you think, the carpet + underlay will be a similar height to the cement board + tile.

As above.

Or, a transition bar, which is for floors of differing heights. About 15mm max I think.

Z bar for me too. The time it gets tricky is when you've got thick tiles plus overboarding plus UFH.

That sounds just like a real salesmans patter!

Z bar for me to. Fitted under the door. I hate it when you see them fitted on show.
