In this tutorial, we learn how to get rid of that smell coming from your shower with Bob Schmidt. First, you will want to clean out your drain pipes to make sure the smell is not coming from there. If the smell is coming back out, you will need to do additional work. If water gets saturated into the base of the shower, then there should be some gravel around it so the water can soak through and go down into the drain pipe. If moisture soaks through the tile grout, then it can bring out the sewer smell that you are smelling. To help this, you will need to use some Simple Green disinfectant and pour it down your mud pan, which will clean the terrible smell you are smelling.
