Five years ago a friend and I made this master bathroom. The floor was pored with radient heat in it. This floor supports a toilet, a bidet and a sink. The walls are equipped with many shower heads so the whole room serves as a shower. So one can sit, shower, and shave!
The problem is that the floor leaks to the downstairs. The lower level bathroom has been is gutted for long time due to the leak. It seems to me when one takes shower water finds a path through a crack in the cement and is then following the radient heat tunnel. The water drips from the point where the radient heat exits the cement it drips to main floor bathroom.
How do I go about fixing this leak problem?
