Uh oh! My contractor just finished laying 122 square feet of porcelain floors directly over plywood in my kitchen.
When I had asked him if he needed me to purchase backer board, he said no, that he could lay it directly over the subfloor. I felt this wasn’t right, which led me to here, but I suppose it’s too late now.
Did I create a bigger problem for myself?
He only charged me $500 for the labor.
It is not recommended by any manufacturer to install tile directly to plywood.
I would recommend getting a guarantee in writing from the installer.
