strengthening cut joist
A joist below my bathtub was severely cut for the bathtub drain. See
My bathtub is out so I figured now is a good time to reinforce the cut joist. There's only about 2" of joist left at the sill plate. This would have been done in the
50's when the house was built.
I asked my plumber if the bathtub drain can be redone so that it doesn't occupy the space where the joist is, but I don't know the answer yet.
There are water supply pipes on the other side of the joist. The joists are spaced 16" apart. They're 2" wide, about 9.25" high and they span 15' of unsupported distance.
The joist is over my garage. So maybe it could be supported from below, although there's some plumbing there. View from below:
As you can see in the picture, I blocked in the area between the joists with plywood supported by 2x4's, in order to replace the bathroom subfloor, and reinforce the new subfloor.
This same joist was cut away below the toilet, but only about 1.5" was cut, so that's relatively a minor butchering.
I may put in a stone floor, so I want the floor to be really stable.
