    Default Bathroom Odor

    I've read through the previous posts on this topic and haven't found anything that quite matches my situation. Here are the details...

    Period in question: 8/5-8/12/2012
    Weather during period in question: hot and humid, some rain, some sun,light breezes or still
    Bathroom: powder room with sink, located on middle floor. We have a basement below, second story above.
    House: built in mid-1970s
    Sewer/Septic: Sewer
    History: We've lived here 24 years, replaced all toilets 1 year ago, everything OK until this past week.

    The odor smells like a chemical toilet, rather than sulfur or raw sewage. Seems to wax and wane: at its strongest, I could smell it from the top floor of the house; at its weakest, it was barely detectable.

    I'm baffled because the toilet and sink are used daily, so the trap should have water in it. The toilets were replaced a year ago, so I'd expect any issues (such as a punctured sewer line) to manifest themselves before this.

    I'd appreciate any help.

    I'd guess a wax seal issue on the toilet. From being used over the past year it could have shifted enough to allow for a less than "gas tight" seal.

    Maybe the base wasn't tightened enough or if the floor is out of level a little bit and the toilet has a little bit of rocking action to it that could also contribute to a bad seal.

    The terlit seals are the usual culprits. If this is a recurring problem, then I'd suggest not using a wax seal, but instead using a SaniSeal. They are a lot more forgiving to movement and excessive plunger-ing. Especially if you have children who want to know if Barbie can swim.

    Step one: do what suggested and look at the wax ring. You can:
    - add a ring, fasten the hold down screws, but don't crack the bowl. But if the double ring is too thick,
    - replace with a saniseal.

    See if this helps - if not, write back. If yes, let us know please.

    Thanks to all who've responded. As far as I can tell, the toilet isn't rocking, it hasn't been plunged, and Barbie hasn't been swimming in the bowl. My husband has (reluctantly) agreed to check the ring. I'll post an update once we've taken that step.

    I hope he means "replace" it when you say "check" it. After all it's only a $3 trial and error step! And once you pull up the toilet I wouldn't trust the seal on trying to re-set the toilet with the old one on it!

    Dump some water in all basement floor drains while you're at it. If it's only when you use the one powder room, you may be pushing gas out only when this room is used. If the basement traps are dry you could get the smell upstairs.

    Another place to look for strainge intermittent smells is the sink trap. If it's used for makeup or if it collects hair, you'll need to take it apart and clean it once in a while. The first shot of water in there after it stands will push the smell right up in your face. The complaint for this one is often smelly water, when it's actually a dirty drain.
    Waste not, want not.
    Use it up. Wear it out. Make it due, or due without.

    did you try putting a bead of clear caulking along the toilet bowl where it meets the floor.

    also your stack could have a crack in it. check for a hole or any signs of decay or crack.

    Calking around the base of the toilet will do nothing to stop sewer gas. How do you check for cracks in the stack when most of it is in the wall? Anything below the toilet would show up as a leak.
