We have a 1970's split level home. The master bedroom is on the lower level of the house, with a very small master bath. There is an existing corner shower, but they didn't install an interior wall - it is just bathroom paneling on the inside of the shower. We want to take that down, and put in backerboard and tile the inside of the shower. However, we are unsure what to do about shower doors. We don't really want to use the existing doors with the metal frame, but we don't want to pull out the shower tray either. Any suggestions for alternatives to keep the water in the shower, while not using those generic doors?
