Thanks! I am doing a few other places in the house, they all have an existing t molding and will need a reducer, what would be the proper way to do it next time? Should I overhang the Lvt tile over the edge to cover the gap? I was worried that it wouldn’t have support under it and may crack on stepping. Or should I do the same thing, leave the gap and glue to the top Lvt?

Ok seems the most plausible way so far, I’ll try tomorrow unless anyone has a better idea :)

From what I’ve read it’s suggested not to mount to either floating surfaces. So maybe will have to make a 1/4” strip of wood in the middle, nail it down in between and then glue to it. Not sure yet hoping for better ideas
