Hi,
Looking for some plumber advice please.
I attach a link to picture which shows a cross-section of my house and where the problem lies.

The smell is coming from the shower drain. The plumber put some chemicals (one shot) down the drain although I have tried some in the past (weaker off-shelf ones I was told). However I am not convinced the problem is solved - if its not what else could be the problem? The waste pipe runs under the floor of the roof extension and is not easy to access. It has been suggested that the toilet could be leaking but if this was the cause I would expect the smell to persist all the time, instead it varies from almost nothing to a heavy from day to day over last few months.
Any thoughts welcomed esp. easy things I could do to eliminate possible causes to help figure out the root problem.
Thanks
JK
