recently got a call from a friend to come help him. He can be a meticulous handyman and remodeler; he can also cut the investing and just finish up according to whatever standards prevail. In the phone call he said, "floor heat and tile, all new plumbing."

The dilemma: how high to go, in terms of standards.

What I saw reminded me of a bad thread in the making. Similar to "screwed up the bathroom reno"
where venting was going to be provided only starting below the Wye in the stack.

The client had bought all materials. FiberCement boards and a tub of mastic. "How to remove this glue?" "Ceramics and Durock" no membrane (walls, floor) in a shower
