It is possibly (probably) a clogged vent. Check the roof and run a snake through the vent in your bathroom down from the roof. Probably clogged with leaves and such. ---

Get yourself a blacklight and shine on your toilet area. You’ll find all the places you missed cleaning. ---

> [@elfkin477](#): > > What you’re missing is that you’re cleaning the wrong thing. Get a mop, thoughly mop the floor around and behind the toilet. Then use a magic eraser or damp sponge on the walls nearest the toilet. I have a hypothesis that the venn diagram of men who pee standing up and men who don’t clean the bathroom is a circle. ---

It could also be a unused sink/bathtub in the bathroom. My master bath has a separate tub and a additional sink, both that go unused for long periods of time. The water that is commonly in the trap slowly disappears, some say it evaporates but I blame the bathroom trolls, anyway, that allows the sewer gas to enter the bathroom, the simple fix is to run the water and fill the traps back up which I have to do every so often. Though I suspect the carpet. ---

Back when we shared a bathroom I convinced my brother that washing the floor was his job thusly him: Why do **I** need to mop the floor? I hate mopping, I don’t want to. me: I can swear on a bible I’ve never peed on the floor, can you? him: ::sighs and takes the mop:: ---

Glue a small plastic fly or stick a silicon target to the inside back of the toilet. Boys can’t resist aiming for either of these. Kym [Previous page](https://boards.straightdope.com/t/why-does-my-master-bath-toilet-smell-like-shit/637841.md?page=1)
