Thanks for your help. The smell has been a difficult one to remove from our bathroom. I'm not sure what else to do, I've tried pouring bleach in the drains and also just straight hot water.

First you have to determine the source. Then we will know how to address it. Regards, Tom

Yes, please let us know if you believe it is coming from a certain fixture.

Tom, I believe that the smell is coming out of the bathroom sink. I've been trying to narrow it down but it's difficult my bathroom is rather small. But it seems like that where it's the strongest.

Sometimes you can have grease buildup in your trap and it rots and then it smells; if this is what is causing it, then you snake/clean the pipe.

Here is a recipe for cleaning junk from your traps including rotting grease and body oil. Mix 1/2 cup of baking soda with equal part of table salt and dump into the drain followed by a cup of vinegar. Next day flush with a bucket of hot water. If the smell is gone it was grease, if its still there we need to sniff the wax ring under the toilet, a likely source of sewer gas.

Most bad smells from a lavatory come from hair built up on the plunger rod and decaying down there. Every time you open the stopper to drain the lavatory you get a nose full of stinky.
The first thing I would look at is the stopper. Pull it and you will find a rod about 6" down in the drain. Shine a light down there and if you see a buildup of hair fish it out. If the stopper's tied down let me tell you how to free it up. Push down on the plumger so that the stopper pops up. Underneath the lavatory ahead of the clip you will see a knurled nut,(Leave the clip on)Now back the nut out until it's free but don't pull it all the way out. Now while you are pulling up on the stopper GENTLY pull the rod back until the stopper clears, stop! Now screw the nut back in place and just snug it up with a pair of pliers. When you clear the drain just drop the stopper back in. Some plumbers lock the stopper in when they install the fixture. I never have for it makes it impossible for the home owner to clean the drain. After you clean the hair pour a 1/2 gallon of bleach down the drain and let it set overnight without using it. Next morning flush it down with a pan full of boiling water. That should take care of your smelly problem. Hope this helps and thank you for rating my reply. Tom
