We have recently moved into a two year old home. I was so excited about the move because our other house had a stinky bathroom. I called every plumber in town and they all thought I was crazy. There were not leaks of any kind and they found no problems what so ever except I had a stinky bathroom. So, as I said before I was excited about getting rid of our stinky bathroom when we moved to our new house. We have been here for 6 months now and the same smell has come into our bathroom. It is crazy! This smell is following us. Could it possibly be the soap we are using souring in the drain. I can't think of anything else. We use Dove white soap. It is a moisturizing soap so I was thinking it may be building up in the drain and smelling. What could be the cause of this smell in two different homes now. It must be something we are doing or using.
