Is this standard procedure for leveling a floor? I have never seen such a high gap between substrates before. I have to really bend my knee to step down from the bathroom into the hallway. I can't even find pictures of such a high gap online. I am wondering why they chose to level the floor rather than just find a middle ground and work from there. A 1" difference in height I could have handled. Anyone have this happen before? How did you handle it? Thinking of having poured floors removed, which sounds like a major undertaking I am keen on avoiding. This just sticks out like a sore thumb as is. Thanks for any information you can give!
