One sink to two conversion (piping question)

I'm doing a complete bathroom remodel and I'm switching from one sink to two. I'm not sure how the piping should be routed. Both the drain pipes and water supply lines as well. I know the Rough in measuraments, I'm looking for advice on how all the piping should come together. Thanks in advance.

One sink to two conversion

Since you haven't done your drains or supply yet, then you should be able to give each sink its own drain and supply lines. Drains should be 1 1/2" from stub out to the main drain, and you should use 1/2" supply lines from your main supply.

one sink to two conversion

Thanks for the info, but here is my question. Do I install separate supply lines to each sink and run them to the 3/4 pipe ( to & from the hot water heater ) OR do I run a tee off of one set of the 1/2 lines and Then connect them to the 3/4 pipe ( to and from the hot water heater ) I'm aware that the supply line is 1/2 inch. When I look in my "how to" book, It shows a basic " rough in" drawing of supply lines for one sink but not for two sinks. Also, will it make a difference in water pressure by adding a double sink? Thanks again for your help.
