thanks in advance to anybody that can help.
I currently have 1 sink in one of my bathrooms with a long countertop. I will be taking out the sink and installing new cabinets with a new 1 piece composite top with built-in double sinks.
There is currently only one drain for the existing sink.
Question is ..can I simply route the drain from the new sink location and tie it in with the old drain location similar to what is done in the kitchen with a garbage disposal on a double sink?
It can be done, but it is a very sloppy installation, especially with a long countertop. Since you are removing the cabinet, a better way would be to have a plumber extend the drain and water lines in the wall to the new location.
