My original general contractor used a very large batch of self-leveling concrete on the bathroom and laundry room floors. One of the reasons it failed is because he poured it too thick, and never cured properly. It will all have to be demolished to make way for the new drain tile anyway.
Although we’ve already roughed in the bathroom framing and plumbing, it will have to be demolished to make way for the drain tile installation. Since we’ll have to rebuild it anyway, Amáda and I consider moving the wall about 16″. This will make the bathroom bigger, and will simplify an overhead white drain pipe.
