Working on my game room bath I have busted the slab up and have the drain line accessed. There originally was a toilet in the same location with the vent going up the side wall beside toilet. The sewer line comes in on the side wall beside the tub and runs across to the toilet. I wanted to add the tub and 2 sinks. The outside sink is 3 ft 8 in from the other sink and I was going to hook those together have the vent come up from the bath sink only? Will that be enough for the 2 sinks? The toilet I have set 15in center from the side wall and 12in from the back. Right now the vent for the toilet goes up the side wall and through the roof can I move it behind the toilet and still use the same hole in roof? or does it need to go straight up? Do I need to have a vent for the tub since it is about 3 ft from the sink....Thanks for any guidance you can provide. Michael
