I live in an highrise apartment unit. I have a terrible sewer smell in my bathroom. After letting the water run for a while I think it is coming from the bathtub drain. The drains is not clogged up and the water is running out very well. I have tried the bleach - hot water thing, taking a bented clothes hanger and the smell is still there. Could it possibly be the water?

Could it possibly be the water?
Does it smell worse at the spout or the drain? Regards, Tom

At the drain.

At the drain.
You say you tried bleach but did you do this?
Most bad smells in tubs, lavatories and showers are caused by rotting hair matted with grease from the soap. Try this for the smell. Tonight before bedtine Take a 1/2 gallon of bleach and pour it down the drain and let set over night. Next morning ,(and this is important) flush out the drain with two large pans of boiling water to loosen the grease and flush the mess out. The bleach will make the hair slippery and began to dissolve it and the hot water will melt the grease and flush the mess away.
This should make your drain smell better. As with all chemicals used in drain cleaning proper ventalation should be observed. Good luck an d let me know. Tom
