So I got a wild hair one day to demolish a small guest bath in my home. I really had NO plan of action, just that it was really bugging me. It was actually the only room in our home that had never gotten a full makeover. When we moved in we had the tile painted and put in a new sink and toilet. The shower was SO small, about 27 by 27! If you dropped the soap, you practically had to kick it out to bend down and retrieve it! This was originally the master bath. The tile was set in concrete 3 inches thick and the floors were 6 inches thick. Just by removing all of the tile, and taking it down to the studs, we gained 2 inches on two sides of the shower. The last 8 inches were gained buy stealing from a very deep [24"] linen closet.
Here are some before pictures.
The small shower area. I believe that these pictures were taken the day they were getting it ready to paint. The blue you are seeing is the filler for the cracks.
I am so happy with the way it turned out.
