We've placed the seal on the toilet, but still have sewage smell in a mail floor bathroom. Yuck! What to do?

Hi Mels...

Is there a floor drain in this mail (or is it Male) bathroom? If so, then I suspect that the PTRAP below the floor drain has dried up and needs water poured down it to keep sewer gases from coming up and into the bathroom.

If no floor drain then let me know what other fixtures are in this room.

Back to you...

Maybe a 'main' floor bathroom? Either way, please answer Mark's questions.
