I had a new shower installed a few months ago and never had a problem with previous one in 23 years. I was away for about three weeks after it was installed so didn't clean it until I came home. I found that the water was cloudy and foul smelling in the small plastic cup just underneath the chrome cover and so was the water underneath it. I used diluted white vinegar and have emptied it once a week but the smell is always there because the water is always cloudy and foul smelling. I used some sink unblocker which stopped it smelling but only for a week - now the smell has returned. Surely this isn't normal for this type of shower trap waste or is it? I contacted the company which was in charge of the installation and they are saying I'm just not cleaning it properly.
