I have a tile bathroom wall. There is an inset ceramic toilet paper roll holder that I would like to remove. It will leave a hole approximately 6" deep (my guess before removing the beast!). How can I fill that hole to make a solid wall to put tile on?
I was thinking of filling it with some insulation material and then a vapor barrier of some sort? Would that be solid enough? I know there are metal mesh patches that work for smaller holes, but I don't think that would be stable enough to tile over without something else hard underneath. Presumeably I have to remove the single border of tile around this hole in order to have some wall to attach things to as well.
Any help would be appreciated! Thank you.
