With persuasion from Heather's uncle we decided to demo the hall bathroom so that we could survey the extent of the water damage. There were mosaic tiles flying everywhere. Luckily, there wasn't very much damaged to the structure of the house caused by the severely leaking shower. However, there was a little funk growing beneath the existing flooring...
With some reservations, we decided to install the kitchen/sun room door ourselves. Getting the door out was the easy part (thank you Mom and Dad for the tool set), but with a little perseverance we were able to get the new door framed in and operating well. I have to say it was one of the proudest moments of my life when the door actually started opening and closing without dragging on the floor and the frame.

Trying to get the shims in correctly

Before: single pane plate glass, rotting frame, and a blocked doggy door

After: dual pane safety glass, steel construction and functional frame
