Horrible bathroom smell

We live in a 1995 single wide trailer. All the plumbing except for the kitchen is centrally located by the bathroom. The washer, sink, toilet, and shower/tub all seem to go into the same area or are connected at some point in the plumbing. Anytime these fixtures are used (except the toilet usually) the bathroom is filled with this horrid odor that comes from under the sink. It's a hard smell to describe. It is downright nasty. I've read that it could be our ventilation pipe on the roof and that it just needs to be rinsed out with water. I'm worried that it could be worse. Any ideas as to whether it's the vent pipe or some thing else entirely? I can answer quite a few questions so feel free to ask!

    Sounds like sewer gas is backing up, sounds like vent pipe...however you say smell come from under sink....check your drain pipes under sink and house..could have some leakage. Any moisture under sink? Any signs of Leaking drain pipes under house?

      @Chelsea Then you maybe leaking under house. Also are you on city sewer or septic tank. I work in a building in town that is on city and we get awful gas back flow from the sewer, coming up threw drains in floors. We can also smell it outside the building.

    I'm thinking maybe the pipes need to be professionally cleaned. In the meantime, try baking soda and vinegar to declog the pipes, then try pouring some PineSol (blue) into all your sinks and drains for freshness. If all else fails, call a professional plumber! Best of luck.

      @Chelsea Ok lets start from the begining. Start by pouring baking soda which is an odor inhibiter down your sinks.Follow by white vinegar and then very hot water.

    If the odor is that bad, I'd recommend calling a plumber. You don't want to mess around with sewer gas or whatever is causing the smell. Better safe than sorry

      If we could afford a plumber we definitely would have called by now :/

    Are you on a septic system or city sewer. I"m concerned cause of the smell outside. I would definitely first check your vent pipe on roof. Animals like to make nests etc. and depending on your climate they can plug with snow and ice. If your on septic . Have you ever had it pumped out? It should be done every 2-3 yrs depending on family size and usage.

      It's possible you have some cracked tiles in your septic field, sometimes caused by vehicles or heavy equipment going over the field. Ask your landlord about this. The roof vent is the other potential culprit. There are plumbing and DIY sites online that explain how to check and clear the line. An athletic neighbor might take care of it for very little pay, especially if the grade of the roof is not steep.

    I too vote for a venting problem - have had the same thing in our bath.

    add Rid X every 3-4 months to toilets for septic tank and keep all vents clear

    What happens if you pour 2 cups of Cloryx bleach down your sink?Do it over night...don't use till morning. Should clean out the Ptrap. That can cause an odor.
