Answer 3

I'm a building inspector It could be the p-trap or vent but also look at to you have a trap. this stops the smell having water in the trap. Also if there is no vent this mite suck all the water out of the trap. You my also have a air admits valve that is not working. this is under the sink and is black or white in color.

I did Home Inspections for Four Years and NOT Very Sink Or Tub Has A Trap!!!!!

Answer 4

You may need to purchase a lysol product and read directions and pour it down both drains. Also a small amount of bleach can take away this smell, make sure it is a small amount of bleach or you can dilute it in a cup of water.   Either of these may help.
