For the past week, there’s been this funky odor coming from the bathroom sink area, even though everything looks clean. I checked the pipes underneath but didn’t notice any leaks. I’m starting to think it’s something deeper in the plumbing. Any idea why your bathroom smells sometimes for no obvious reason?

I know exactly what you mean — I battled that same weird bathroom smell for weeks, and it made no sense because everything looked perfectly clean. I wiped down the counters, poured vinegar down the drain, even checked under the sink for mold, but nothing worked. Eventually, I learned it was caused by a dry P-trap, something I’d never heard of before. This article explained it clearly: dry p trap smell . After running a bit of water to refill the trap, the odor vanished almost instantly.
