We had a single sink vanity in place. Now we're remodeling and will be getting a 60" double sink vanity. Unfortunately I cannot use the stubs/drain that are existing, because the vanity has cabinet/drawer vertical supports that are right where the current supplies stub out.
Can someone tell me how to go about resolving this? I can sweat pipes and know about the fittings for the drain, and the tees, elbows, etc. My main concern is the layout & design - I really don't want to mess with the main drain line or the main vent stack - I want to tie into those. With the drain line - I'll have to drill large holes through several studs to pass the ABS drain through to both sinks. What is code restriction on size of holes to drill through studs? And how many holes can I drill and how far vertically between each hole? I'll have to drill holes for hot, cold, and drain.
