Yes sir, I wish I could. The problem is that this bathroom has a sloped ceiling. It is part of a 1940's attic that was converted to living space many years ago.
The back wall is about 4' high, enough to accommodate a toilet and the back portion of the shower, but not tall enough to support a mirror/lav and shower head. The bottom wall, where the shower head and lav are going, is the stairwell wall and almost directly above it is the ridgeboard of the house, so I want to avoid making another roof penetration this high up the roof, although it would be much easier.
Preceding this, I had to rebuild the entire second floor since they utilized the original first floor 2x4 ceiling joists as floor joists for the second floor. I'm actually amazed how much wood will deflect before completely failing. This is what we found when we tore out dinning room ceiling; we knew we'd had no choice but to tear it all out and start over. And yes, those are scabbed 2x4's spanning over 12' supporting a bedroom.!
