Sewer gas in bathroom? I just moved in yesterday and after the first two toilet flushes, I now can't enter the bathroom without dry heaving. I don't have a sense of smell, but I think it's sewer gas? I called a couple plumbers but only got voice mails (of course it's Sunday). The house is 700 square feet with one bathroom and a full basement.
The sink in the same bathroom had a siphoning s-trap that was also rank, p-trap and a vent for you sir! Immediately after finishing the shower drain I found a leak had sprung from this botched silicone joint going into the cast drain. The bad news is that any number of things can cause a sewage smell in your bathroom, and it can be difficult to pinpoint the source of the odor.

These hidden causes can let sewer gas sneak into your bathroom, carrying gases like methane and hydrogen sulfide that you definitely don't want to breathe in. The good news?

I'm suddenly smelling sewer gas in a bathroom when the attic fan is on, and I can't figure out the source (and yes, I flushed:p). We use the attic fan daily, and the smell just started today. Turn the attic fan on, and you get the sewer gas within a minute or two.
Turn the fan off, and once. Why does my bathroom smell like sewage or rotten eggs? A strong sewage smell in a bathroom usually means sewer gas is getting into the room. Common causes include a dried-out P-trap on a sink, tub, or floor drain, a loose or failing wax ring under the toilet, or a venting issue in the drain system.
A sewer gas smell in the bathroom can be caused by something as simple as water missing from your P-trap, but it could also be something much more serious. Start tracking down the problem by checking for simple issues first. If you can't find a simple problem, you may have a large issue to address.
How to Diagnose Sewer Gas Smell in Your Bathroom Diagnosing the sewer gas smell in your bathroom involves a few systematic steps. Step 1: Identify the Source of the Smell Inspect Fixtures: Check all bathroom fixtures, including sinks, toilets, and bathtubs, to see if water is pooling.

You may experience a bubbling sound coming from the toilet or the drain as sewer gas forces its way into the bathroom. It smells like sewer gas whenever we use the upstairs bathroom. I'm away on a trip atm, but I'm going to make sure to run some water in the shower when I get back.
