What are possible reasons for an odor coming from the toilet even though it is clean?
For the past year I smell an odor in the bathroom and it appears to be coming from the toilet. I constantly clean the toilet inside and out. However, nothing seems to work. I open the window and when the window and door is closed for a short period of time and one walks into the bathroom, the odor is there again. Could it be that the seal is loose and fumes are coming from the pipes. The toilet was professionally installed over 3 years ago and everything was fine until about a year ago when I began to smell the odor.
