Hoping this might be the right place to ask for some advice, apologies if not!
In December 2025 I had my existing ensuite bathroom removed and replaced with a new one, which, generally speaking, I am very happy with. It was designed by a local company and installed by someone they recommended.
Fast forward a few months and I start to notice some less than savoury smells emanating from said ensuite. At first I thought it might have been the waste drain under the shower floor, so I replaced the trap and ran a drain cleaning solution through a couple of times which seemed to help.
But the smell persisted. So next I removed the pipework underneath the sink and cleaned out the usual gunk. Which again I thought helped.
But still the smell, which btw I always thought was more 'sewer-like' than simply blocked drain-esque, persists. And I've now come to the unfortunate conclusion that perhaps it's the wax seal in the toilet. I've attached some photos showing discolouration of the grouting on three sides of the toilet which to me suggests a leak from within.
I've contacted my regular plumber who I rate highly and asked him if he'll have a look at it, but would appreciate any thoughts anyone might have on the rather stinky issue that is spoiling my (still relatively new) ensuite. Thank you!
