I'm dealing with a small master bath off a bedroom. The floor joist in the bath are
as shown in the attached picture. Each floor joist is a 3(w)x9(h)x20(l) which rest on the main beam (dotted lines in picture). The left most beam 2(w) x 10(h) is attached to a block wall. The full round circle on the left between the two beams is the current toilet location (4 inch ABS soil pipe). The half circle is a 3 inch ABS shower drain where the original plumber notched the beam -- hence the half circle. Per picture, to accommodate the original toilet soil pipe, one beam was cut and blocked such that the two adjacent beams now bear the load (weight).
The desire is to redo the shower such that the shower is moved over the toilet area and the toilet is moved over the shower area. I believe I can find a shower pan where the hole in the pan will go between the beams.
My problem is the toilet, in that the soil pipe will be directly located on the notched beam, such that the notched beam will now need to be cut and blocked. This would then cause the floor joints to have two blocked beams next to each other. There is "no way" the original block floor joist can be replaced.
My concern is the beams being over loaded (to much weight). Any comments and solutions appreciated.
