I guess this is what I get for having a WebTV and not knowing how to
up-load pictures... LOL

The new medicine cabinet is TALLER!
It's a STUD that had to be notched!

Anyway, I took a piece of scrap plywood and cut it to fit the master
shower and wedged it in place against the tiles with some 2x4's. This
kept the tiles in the master bath shower from jarring around as I
notched out the stud from within the guest bathroom.
She's all framed in and looks nice. :-)
Thanks for your help,
Dave
