I was laying out tile in a half bathroom before wondering if I should tile under the door or not. The picture below shows the tile (top), plywood subfloor where the door will be (middle), and laminate flooring in the hallway (bottom).
There is a cement backerboard underneath the tiles -- this strip of plywood is all that's left of the old subfloor. The hallway leading to the bathroom has laminate floor over what I think may be asbestos tile. To keep those tiles encapsulated I plan to put some sort of molding or threshold between the two rooms.
The height of the laminate floor above the plywood is about 3/4", and I expect the 5/16"-tall tiles to be about 1/2" above the plywood once the thinset mortar is down.
So: should I tile all the way to the laminate floor (under the bathroom door), or leave the tiles as they are in the picture? Seems like the latter solution would make it easer to put in a threshold/molding, but it also seems odd for the flooring under the door to be nonexistent.
