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?

Does it leak from one spot or multiple spots? How big is the bathroom? What waterproofing did you do to the floor? Do you have pictures? Can you crap and shower at the same time? –  DMoore Sep 25 '13 at 1:51
it leaks from one spot and sometimes around the toilet its the one spot that comes from radient heat exit that needs to be addressed . some of my mistakes were forgetting to put fibers in the cement mix, also we never sealed the floor –  carmine scopino Sep 25 '13 at 2:01
If you are going to have a toilet in a shower area then you basically have to do the same waterproofing as the shower drain. Also the leaking has little to nothing to do with the cement mix. No amount of fiber will make cement nonporous. You are going to have to explain better how you waterproofed the walls and floor. –  DMoore Sep 25 '13 at 4:35
It sounds to me like you may have made a few mistakes while building this bathroom. Most importantly, not waterproofing the floor/walls. You haven't provided enough detail about how the bathroom was built, so it's difficult to give a detailed answer. It sounds to me like you might have to rebuild parts of the bathroom, to properly resolve the issues you're having. –  Tester101 Sep 25 '13 at 10:21
If the whole room is a shower, where do you keep the TP? –  Tester101 Sep 25 '13 at 10:22
