The house we live in was built in 1972. Over the years we have done what we can to keep it in good shape and livable. The one room we haven't done much to (except for paint) was the upstairs bathroom. One month ago on a Saturday, we started demolition.
Here it is with new sub floor around where the toilet will be.
Then we put down cement backer board to make the floor nice and water tight. YES!
We put in the new tub and closed off the window put in new insulation and smiled a lot.
We covered the walls with green rock, which is about the same color as the green we had painted the walls.
Then we mud and taped.
Next we put in the ceramic tiles for the floor. This the 3rd time this floor has been done. It will be the last. Once the ceramic tile was in and dry then we could put in the toilet. We were one week without a toilet upstairs. Then we finally got paint up and put in the new tub surround. Looks really nice.
