I want my tile to extend into our walk in closet from the bathroom . I put a new sub floor in the bathroom (3/4 ply ) but don't want to rip out the T&G in the closet ( just a pain in the ). It's an old house with 1" T&G over the joist's .The closet is 5' by 8' and I was wondering if it would be okay to put down 1/4" intergaply over it and then tile .
