Need advice in fixing "contractor's" botched shower floor tile job
Definitely file this under "if you want it done right, do it yourself". We recently finished a master bath/bed remodel in which we contracted out a few portions that we could have done ourselves, but with very busy full time jobs, decided to pay for speed and hired out to professional contractors. One of these was the bathroom tile.
I designed a very detailed layout, ordered the tile and hired a tile contractor we used before on a smaller job (actually, to finish the tile work on another, smaller bathroom that I couldn't get to with a crazy work schedule) - he did a good job finishing the 1/3 of the tile left and we decided to hire him again for the full tile job here.
Waterproofing was the Schluter-Kerdi shower base, membrane and band system.
Floor tile is 2" square mosaic shower floor tiles.
After a few months, I noticed the grout had cracked in the shower floor on a few tiles near the drain. When we ground out the grout, the tiles began just popping out and we quickly realized he removed a significant portion of the waterproofing membrane around the drain and the shower base was very wet! I assume the moron did this as a fix to the lack of a slope near the drain which we pointed out when he first put the tile in (which I assumed was due to him using too much mortar on these tile near the drain).
Note the Schluter-Kerdi system includes a pre-sloped base. Needless to say, we kept removing floor tiles to see how far back he removed the membrane. Words fail to describe how angry we are with this clown (especially after all the grandstanding he made about how ethical and responsible he is in his work as a Christian).
Finally, my question: what is the repair here? I'm tempted to take out the floor tile fairly far back, perhaps even to the shower walls, cut out the foam shower base since it is now pretty compromised between our digging out the tile and the "contractor's" botched job, and replacing the slope with a mud shower bed over a rubber waterproof membrane (that's the system I put in MYSELF in the other bath which worked very well), which would probably mean I overlap the rubber waterproof membrane over the remaining Schluter-Kerdi membrane to create a waterproof seal, then fill in the void with mud? Will this work?
Is there a better approach? Please don't say bring in another contractor - I'm very burned out at starting with another contractor at this point and am confident in my skills.
Thanks - sorry for the long post!
