hi all after some advise am currently about to refit my bathroom, floor is boarded over a 2 x 2 framework onto concrete floor i want to tile the floor however the current boards sit about 3/4 of an inch higher than the hallway floor which is concrete so when i remove the boards and framework it will leave the bathroom floor just under 2 inch lower than the hallway , when it's tiled i want a pretty level finish between the floor , any ideas?
