I’m converting a single basin lav to a dual. I’ve seen the threads here about p-trap and venting to prevent siphoning. Great stuff!
My question is about the placement of the drain line penetration.
Is there a distance between the bottom of the bowl and where the waste line penetrates the wall that is optimal so that fitting a p-trap works out nicely? Or, measurement from the floor where the drain should roughly be regardless of overall vanity height?
My house was built in the 60’s so the existing plumbing and vanity are much lower than current standards. I’m going to be opening the wall up to rearrange the pipes and venting so I’ll have the opportunity to place the height of the drain optimally.
