I am remodeling a small bathroom (9x5). The floor slopes along the 9 foot length. There is a 1/2 inch difference from one end to the other. I realized this after installing the subfloor. Do I need to be concerned about this? What is the best way to handle this? I've been told not to worry about it. Just thought I'd get another opinion or two before proceeding. I thought about taking up the subfloor and shimming the joists. The floor is flat and level in the other direction. It just slopes the one way.
