We had our master and guest bathrooms completely remodeled to the studs last September. Our contractor was amazing and seemed to know what he was doing. We are very happy with the final products.

However, the guest bath single sink started smelling like sewer gas a couple months ago. We snaked it and found nothing lurking in the drain. We add Draino, let it set for a few minutes and rinse well with hot water but the smell returns in a week or so.

Any idea what’s going on? The two sinks in the master bath do not smell at all.
