This would not be a good idea because if you get any back draft which is likely when the vent isn't working then you have one smelly bathroom.

Shouldn't be a problem. You may need to extend the pipe at the sink a bit to put in air vent so that the drain can vent. It is a checkvalve that lets in air when the sink drains. Or you can tie into the existing vent stack if possible.


What causes gurgling in one bathroom when another bathroom is used?

A vent for the drain system may be blocked. A home or building plumbing system must be "free flowing" with a vent to the outside atmosphere - usually through the roof. When water is forced down the drain and the vent for that drain is blocked, air will be pulled from inside the building through another plumbing fixture causing the gurgling sound. The main drain line may also be partially blocked whereas when water is forced down the drain the air in the drain line may be forced back into the building through another plumbing fixture causing the gurgling sound.


What is wrong if there is a smell of sewage coming back up your bathroom pipes?

Your drain waste vent is plugged or leaking somewhere. The drain waste vent is a pipe that carries sewage gas out of your home, exiting usually the roof but sometimes the side of the house. Get it fixed asap, this is not good for you.
