A double bathroom sink installation rarely requires more than one p-trap. The usual practice is to connect the two sinks to a tee and then feed the tee into a single P-trap, which will connect to the drain.
If you are installing a double sink, you will need to make sure that you have the correct type of pipe for your sink. If you don’t know what type you need, check with your local plumbing supply store to see if they have it in stock.

Does a double sink need a vent?
All kitchen sinks need vents. Negative pressure within the system is created by air not being able to get into the pipes. This can cause sewer gas to leak into your home. To prevent this from happening, you need to make sure that your kitchen sink vents are properly ventilated.
The best way to do this is to use a ventilator, which is a device that allows you to control the amount of air that is allowed to pass through your sink. Ventilators are available in a variety of sizes and styles, so you can find the one that works best for you.

What happens if plumbing is not vented?
Poorly-vented drain lines won’t be able to effectively move wastewater and solid waste out of your building.

If you do, make sure that it is properly ventilated to prevent the water from seeping into your home.
