is Gypcrete under a tub sufficient and what about the toilet flange?
I'm having radiant heat installed on my concrete floor in my previously finished basement (which I am remodling currently and it is down to the studs). I understand that the tubing for the warm water will be covered with some depth of Gypcrete so this leads to three questions that I want to throw out to the crowd.
1) What is the minimun depth above the tubing that I should insist on?
2) I am also replacing the tub and toilet in the bathroom- should I block off the area the tub will sit and use something besides the finished Gypcrete to set the tub on?
3) Am I going to need to add new or raise the toilet flange and waste pipe?
I am having proffessionals do much of the work but I am acting as my own GC so I'm trying to ask all the right questions I can think of.
