I would like to switch the location of a 2-sink vanity with that of a 2-showerhead shower. The spaces are comparable. Does one need two floor drains under a 2-sink vanity or could the single shower drain serve both sinks? Yes, I would use a contractor/plumber to do this, but just wonder about how big of a plumbing adventure this would be. (This is a second floor bathroom with a fabulous view, currently obscured by poor layout.)
Thank you!

You're planing a indirect waste on your vanities? You wish to swap locations? What will you pick up the shower with? You better run this past your plumber and g et his take on it. You're about to run headlong into code issues. Good luck, Tom
