I would like to move the bath sink to the left approx. 1.5ft. I currently have a vanity base and want to change to a pedistal sink to make bath feel more open. Can this plumbing be moved inside the interior wall? I have a concrete slab so the location of existing drain outlet can NOT be moved by me. What is my solution?

Hi there DonnaDIY...

Sounds like you're on track to me. You should be able to open the wall and simply extend the pipe to the left the additional 1.5 feet you need... either using a coupling of same material or by installing a MISSION OR PROFLEX STYLE BANDED TRANSITION CLAMP (see picture). This clamp is available at most home supply stores and is great for transitioning from older metal pipes to newer PVC/ABS plastic pipes.

For a pedestal sink I would DRY FIT (don't cement) the stub out from the wall and then patch wall as needed. After all is patched and painted and the pedestal is in position you can measure the pipe length needed to hook up the ptrap and cut the dry fit stub out to proper length. They make a nice chrome plated to plastic pipe ptrap that requires this step (let me know if you want picture/info. On this).

Let us know if you have questions...

Now that you have a pedestal sink let's dress it up with a exposed chrome bottle trap,(see image). Good luck, Tom
