Bad smell in down stairs bathroom

Question

Every once in a while this horrible smell cones out of the bathroom. Smells like urine. It will be there for a few days to a week then goes away but it is overwhelming when it's there . The bathroom is clean. And it comes and goes. What could it be?

I don't think that dupe provides the mostly likely answer, which is simply a dry trap. — isherwood, Jul 17 '17 at 18:14

Do you use that bathroom often? If the sink goes without use for an extended period of time you might get a sewer gas smell. The p-trap in the sink drain can dry out causing sewer gas to leak through the drain. The next time it happens run water in the sink and if you have a tub or shower then there too. See if it helps.
