The pictures below tell most of the story. I'm putting in a new bathtub (one of those prefab units) in my house on a slab foundation. Turns out there's a large hole in the concrete around the outgoing drain pipe. I'd like to do the right thing here, but I'm not sure what that is. Are such holes around drain pipes simply the standard? If it was your house, what would you do?
