Pride Plumbing came out and provided a cost estimate to replace a single-basin bathroom sink with a new customer-supplied double-basin bathroom sink. This would require us to 1) remove the water and drain lines from the single-basin sink and remove it; 2) cut the sheetrock and run additional PEX water and PVC drain lines for the new double-basin sink, adding supply stops where needed; 3) once the water and drain lines are stubbed up, build the double-sink vanity and secure its cabinet and top to the wall and seal around it; 4) install new customer-supplied faucets for both sinks and attach their water supply lines; 5) connect the sink drains to their trap adapters; and 6) test for leaks and proper functionality.
