I've just had a similar thing. The guy who is tiling my hall said he would include fitting a wooden 'threshold' to bridge the gap from tiles (higher) to wooden floor.
It became a non issue in the end as we found thinner tiles but he showed me examples and it looked fine.
Yeah, this has been "done", but it seems that means different things to different people. One door is fine but they seem to have forgotten another two.
The pic is someone else's. I don't need mine for carpet, it's for tiles to laminate gap. But thanks both for the name.
