I recently replaced a kohler toilet that I have been having problems with ever since I had the tile replaced in my bathroom. It always seems to smell like pee in the bathroom. Originally, the guys re-installing the toilet did it incorrectly and it leaked from around where the toilet sits on the tile. I had to get roto-rooter to come out and charge me lots of $$ to fix it. It quit leaking but the smell still lingered. When the toilet started to fail (water was running all the time), I decided to replace this 20 year old toilet with a new Kohler Memoirs. I pulled up the old toilet and noticed that the wax ring was perfectly in tact. (it was one that has a flange that fits into the waste pipe.) There was very little to scrape off the waste pipe. I noticed that the new tile floor sat about 1/4 inch or so above the closet flange. I put the new wax ring (same kind as was on before) on the toilet and placed the toilet over the waste pipe and T-bolts (new). I didn't notice any resistance from the wax at all but still applied pressure and attached the bolts. (the toilet does not rock, move or leak). I notice the pee smell still there, I am not sure if it is from before or continuing but if the wax is just helping funnel the waste down the drain and there is no "smush" of wax, would that cause a smell? should I use 2 wax rings to be sure? not sure what to do. Thanks!!
