Looking for some advice on the below. I have a 1/2 bath and 1 additional sink I will be plumbing in a stem wall slab foundation. Is it safe to run the two sink drains and the vents and water supply lines in the exterior wall or would it be a better choice to move the sinks and toilet on an interior wall? Any suggestion on the best way to do this per code would be appreciated........
