I am currently in the process of a master bath remodel, and I have a question regarding the venting / drains for the new double sink vanity that I plan on using. I will be moving the vanity to the opposite wall and building a lager shower in its place. On the new wall there was previously a toilet and one side of a corner tub. The toilet is being moved down the wall from the right side to the left side and the vanity will be on the right (all when looking at the wall).
When I look at the existing plumbing, there is a drain that was used for the corner tub that I would like to use as the drain / vent line for the new double vanity. When I look at this set up I see that the vent pipe is offset to the left from where the center of the sinks will be. I am looking at my best option for plumbing the two drains to this existing stack.
Please see the photo that I have attached for the 3 options I have been thinking of.
1) To run two drain lines from the stack basically parallel (red Lines)
2) To run a loop that spits the sinks and has a left and right branch (Blue Lines)
3) Going in the room behind this wall and tearing up some more floor so that t can get to the lower portion of this drain (currently it is blocked by a Joist directly at the base of the wall that is hiding all of the lower components) once in the floor I will move the vent stack over to the right (green Lines)
I am not sure what option is the best or if I missing something here (like the two drains have to enter the same fitting.
Also if anyone has a comment as to the moving of the toilet you can see that in the photos as well. The stack goes up to the attic at the right and down to the sewer at the left end of the room. I was just going to move the Y fitting and the flange closer to the drain side.
Thanks in advance. As I know I will have more question as time goes on (this is only the beginning)
