We had a new downstairs toilet fitted about a year ago and in the last few days there has started to be a smell which i can only describe as being \\\"urine\\\" like that in a Mens public toilet at a football ground. There is only a toilet and a sink in the room and we have cleaned thoroughly, the smell seems to vary in intensity, the water in the pan is clean and flushes away fine. i cannot see any leaks around the actual wc and the main soil pipe is visible to where it goes into the ground and is not leaking as far as i can see. Hopefully the smell may be a clue as it is quite distinctive, as any bloke will know!
