We spent last weekend and a couple of nights this week getting everything ready to tile in the bathroom. Since we want to be able to get the whole floor wet without worrying about it getting funky under the tile we went ahead and covered the whole floor with a PVC membrane. It is a bit overkill, but at least we know it is done right. Next we had to get the slope correct so that the water goes toward the drains. I cut some thin strips of wood with the proper slope to help guide me as I put down the drypack. It ended up raising the floor almost 2" at the far side. The first time I did the dry pack I made it too dry, and I had to go back and redo it all a couple days later. I got it right eventually. We are going to spend the weekend tiling, and will have all the floors done, and hopefully a good deal of the walls too. My wife can't wait, it has been almost 8 months since I tore our old shower out. Did I ever mention how wonderful and patient she is?
