started with a simple replace but the shower i got would not fit in to the door so 1 bow window and 2 inside walls later i got it in. I ran into some black mold that i had to remove and some sub flooring that had gotten wet and swelled from the old shower. What started off as a 2 hour job took me most of the week end. Every one i have shone it to have loved it and i have 3 of my friends that want me to redo there baths now. Wish me luck that thay go better then mine .
