Horrific bathroom odor

We replaced our tub, toilet and sink in April of 2007. Every since then, anytime the temperature drops into the 60s or lower, our bathroom is filled with this horrific smell. It's bad enough that we have to keep a candle burning in there and an automatic air freshner at all times just to be able to go in there. Any idea what might be causing this smell? :(:confused:

Did you put tile down on the floor? If so, the toilet should have been installed with an extended flange or double wax ring. Does the smell come from the base of the toilet? Does the toilet rock any? If the toilet rock, try tightening the nuts just a little. Do not over tighten or you will crack the bowl.

That is kind of what I was thinking too, perhaps a leak around the base of the toilet. It is weird that it only smells when the temperature drops though, because it seems like it would work the opposite way.

I would check for leaks around the toilet and also around the tub first.

Re: Horrific bathroom odor

No we didn't put tile down, the floor was already tile. Yes the toilet teeters from side to side just a hair. I've tried tightening the bolts but it didn't help so I caulked all the way around the base of the toilet and it stopped the teetering for a little while but it didn't help the odor at all. Thankfully it doesn't get down to the 60s very often here in Central Florida. I would like to get to the bottom of this though.

Re: Horrific bathroom odor

Do you have a ventilation fan to exaust moisture/odors provide an air exchange? or do you rely on an open window during such activites (less likely to be opened if it is COOLER outside;)!)?

Does your plumbing vent through the roof or terminate in the attic or through an outside wall?

Checked vents outside (exaust fan and plumbing) for signs of clogs/dead animals, abandoned birds nests, insect nests/hives, etc.?

Is it possible "somebody's" diet changes :eek: :o and whichever venting system isn't employed by same "somebody" when its cooler (or rarely even when its not but more overall air exchange in this area to the outdoors during warmer months)?

Assuming the bathroom is regularly cleaned top to bottom:cool::).

Previously teetering toilet might have leaks from waste or from floor stinking up subfloor. caulk no substitute for properly supported, leveled and set toilet - may have needed shimming (use PVC or ABS plumbing shims or similar). With tightening up to such degree, not replacing failing/damaged wax ring, etc. may have cracked closet bend or flange below.

You mentioned replacing fixtures last year. Don't know if you simply replaced or relocated and/or condition of fixture vents, may have damaged one for example - pierced with a nail through a wall surface, cracked or stressed a joint/union - may be you only notice the smell when it is colder because the colder wall cavity or floor space is cooler so the smell/gas doesn't rise up towards the attic/roof and out the house driven by a "convection" draft.

I don't know about toilet venting, but I do know there is no exhaust fan. I'm also sure it's not someone's diet :p because here in central Florida, you can go to bed and it'll be 78 degrees and get up at 2am and it'll be 52 degrees. I've gotten up many nights at 2 or 3am and the smell about knock me out the second I open the door. As far as relocating, no we didn't do any of that. We simply bought a new toilet and removed the old one and put the new one in it's place, I know we used a wax ring and a flange. We did the same with the tub. As far as the sink goes, we ripped out the old vanity and put in a pedestal sink because the bathroom is only 6' x 8' and a pedestal sink takes up less room. How would I know if the toilet is vented and if so how and where is it vented to?

DWV stands for drain waste vent things can't drain unless the air can displace and vent. Not unlike using a drinking straw like a pipet if you take your drinking straw in your drink glass with water and put your finger over the end of the straw to seal it, then withdraw the straw from the glass the straw will hold water until you release your sealing finger off the top..you can do some research on "how does my plumbing work" and find out more for yourself.

Back to the horenous odor....

The newly installed pedestal sink you just mentioned ..... Ah ha!

I'll bet your new pedestal sink came with or you installed with an "S" trap.

"S" as in syphon.:rolleyes:

If it does - that is probably the reason/point of entry of your horendous odor - sewer gas venting up into your sink and filling the room! Pluging the sink wouldn't work to stop that - as it would still waft up the intregal overflow. You'd need a P trap. You can get them chromed cheap metal, chromed brass or plain brass (harder to find except at specialty plumbing supply).

An offending "S" trap on a pedestal lavatory would also fit your symptom set - cooler denser night air outside above the roof and cooling the top of the vent stack, warmer less dense air in the bathroom - since nature goes for an equalizing - that gas and odors flow more readily into your sink's waste arm, up past the dry (syphoned) unsealed (by standing water) trap and into the room than to denser (think heavier) cooler air up at the top of the vent stack above your roof in the cooler night air. This could be odors from the waste sitting in your lines, or if your home doesn't have a main trap you could even be venting noxious gas, odors, and toxic gas back from the sanitary sewer up through a dry trap.

Don't burn anything in the bathroom, sewer gas (methane+) is explosive.

Re: Horrific bathroom odor

First off let me ask who did the plumbing? I dont think an S trap would evaperate that quickly or with just 20 or so degree temp change. Can you pinpoint the offending aroma? Alot of times the overflow from a tub is not connected properly. Try to figure out where the smell is the strongest to narrow the search

Re: Horrific bathroom odor

We had a contractor come in and do the plumbing. As far as pinpointing the odor, if you're talking about location all I can tell you is it's in the bathroom. I've gotten down and smelled around the base of the toilet, the sink and the tub hoping it might be stronger at one point or another but it wasn't. If you're talking about what the smell might be, it smells like someone pumped out a septic tank and dumped it in my bathroom. I also checked the trap on the sink and it's a regular P trap like what's on my kitchen sink. I also did some checking on the vent and there is one main vent for the whole house. It's in the wall behind the bathtub, next to the toilet. It goes straight up the inside of the wall and out through the roof. (if that helps) Woke up this morning around 8am and the thermometer on my porch said it was 64 and the smell was unbelievable. Even with the door closed and the bathroom window open, the smell was seeping under the door and if you walked past the door in the hallway, it would darn near gag you. I'm afraid I'm going to have to call a plumber. We're getting on into what passes as a Florida winter (January is our coldest month) and I don't know how much longer I can take the smell. It gets worse everytime the temp drops. :(

Re: Horrific bathroom odor

I had the same problem in my bathroom. I replaced the drain with the "P" trap and it solved my problem.

Good Luck! I know only too well how bad it can get!!
