Uggg I have a mildew odor in my bathroom and not sure why? I looked in cabinet and its dry. Inside shower stall has odor too. I have wiped everything down. Not sure where it's coming from. Anyone have any ideas?

I checked for leaks underside and didn't find any. Saw the cheater vent and changed that. No smell this morning.
Thank you all for your help.

Bad air admittance valve, AKA "cheater vent", maybe. Rule this one out. Easy to replace; about $10.00 at Home Depot

Look from under the flooring to see if anything has leaked. Drains on showers have a nut to pull the drain down for sealing. Seals have been known to leak and I have seen some nuts come loose.

Has it been a while since using RV shower, so maybe P-trap is dry, allowing odor from tank?
