Just got the tub and ready to set in a mortar bed. I have one question first. I plan to cover the mortar in plastic, but the bottom of the tub is a grid with cavities about 1" or so deep, lots of them. My concern is that the plastic will prevent the mortar from completely filling the cavities and I'll have a bunch of small air pockets. I don't think it would affect the tub in terms of flexing because they would be so small, but still wonder. I could go without the plastic, but that just flies in the face of conventional wisdom for preparing for when the tub will eventually come out.
thoughts?
