middle of the room or the door entrance.

I am trying to lay tile in a front entrance and adjacent bathroom. About 3 feet in from the front door is a joist that sits about ¼ inch above the rest. As a result, there is a steep slope in the sub-floor between this joist and the joists on either side of it. The joists run parallel to the front of the house and the wall the divides the bathroom from the rest of the entranceway. However, because this joist lays about 1 inch away from the bathroom wall for about half its length it will be difficult to access the sub-floor in this section. Plus I need to tile on both sides of this dividing wall.

At the moment I thinking it would be best to rip up the floor around the joist and plane the joists top until its level with the surrounding joists. But the proximity of the joist to the bathroom wall would make this tricky. Self-leveling cement has also crossed my mind, but I think it’s a much weaker solution.

Any ideas would be greatly appreciated.
