So here are the pics. Here in the beginning, you can see the dry rot / water damage went all the way through the insulation. They had to remove it and replace that too.
The entire shower was gutted and rebuilt.
A new cement bottom was made
And here are the boxes of tiles we chose.
Tile going in.
I had them do around the tub too.
Tile in, but not yet grouted.
And here's the grout. Looking really good!
Finally, the glass! We went with frameless. I think it looks beautiful!
And done! Finally! The actual work on the shower took one week. Then it took about two weeks to get the glass in (not sure why it took so long, but it did.) But we're very pleased!
