I am retiling my upstairs bathroom. In the past I have just done it right onto the subfloor. This time when I took up the old there was backer board between the subfloor and the tile. Is that something that is new and necessary or just what the last person did in my house?
I am using 18 x 18 Travertine tile and replacing the contractor grade 16 x 16 porcelain stuff that was in there before. The tile I am putting in is about as thick as the old and backer board combined.
Thanks for any help or suggestions
