I am renovating my ensuite bathroom. I am adding a shower stall (42x34, composite concrete base), and moving the toilet over to accomodate this. After ripping up part of the floor, I was surprised with what I found, now my original plans may be somewhat challenging.

In the picture below, the T represents the new location for the toilet, and S is the new shower drain. It appears I have no choice but to go through the joist to the right of the new toilet location.

Just wondering what others would do given this situation...
