Myka, I believe subfloors are required to be 1.25" thick for tile, typical subfloors are 3/4" so when tile is to be set builders lay an extra sheet of 1/2" on top. However depending on the builder extra 3/4" may be more available so they may double up on the 3/4" to make 1.5". I've seen this a few times before so I wouldn't doubt it, but even 1.25" is plenty.

as true as it is not many people use the required thickness for subfloors(5/8" or 1 1/4 including the original ply) ) most just use 3/8" to match with hard wood easily by the time tile goes on........
