we have replaced the flooring around our toliet two times now, and again the flooring is wet and ruined.

When the project first began we put a sub floor down, when we installed the toliet we used a double wax ring, the system failed we replaced the flooring again and the flange and the double wax ring, and guess what the floor is ruined again. Please help. A friend has suggested that we use stainless steel crews? Any help would be appreciated seems like there should be some solution to stop the toliet from leaking.
