The first step was to remove the doors an the top bar.
Chrissy took this opportunity to re-caulk the entire tub, as well as the holes in the wall from the old frame.
This project was pretty simple and made a big difference in our bathroom. I encourage everyone to ditch their dated doors.
I'm happy to report we put the old doors and frame on Craigslist and someone picked them up, so they will get a second life.
