Every manufacturer of LVT will have a matching threshold available to use in the doorway. It will accommodate expansion and contraction, is cheap, is easy to install, will be low profile and will look better than your existing thresholds or anything you mill on the table saw. The only thing pinning the LVT down will be your toilet but with room to expand around the perimeter it will not cause a problem.

Our thresholds are 9.5" wide by 3/4" tall, and I think, original. I don't think we'll be getting rid of them, and I suspect the thresholds available from the LVT folks won't play well with our existing thresholds.
