I have a small 4 x 8 bathroom. Three years ago I had a new vinyl floor installed along with my kitchen. The plumber took the toilet out when they did the job. I told him that I occasionally had water on the floor around the toilet. He said it really wasn't leaking, it was sweating. He put a new wax ring on and that was that. I still had water on the floor around this toilet on occasion. He did not seal it around the bottom. I have an open basement under this bathroom and have never seen any water on the wood from the basement. We removed the toilet today as it was loose and we decided to see what was going on. It was dirty underneath and looked as if there had been water there, but no damage. Now I am wondering if the flange is damaged and how can you tell. The flange that is there is flat on the front and back and sort of raised on the sides where the bolts go in. There is also a lot of wax stuffed in between the flange and the floor. All of the flanges I am seeing seems to be flat all the way around. Also, is it possible that this toilet is sweating? I have been in this house 24 years and have always had this problem. Also, there is a heating duct right next to the toilet if that makes any difference. This house was built in 1962.
