 Bathroom sink pipe configuration
Author: talksthetalk (CA)

I am a homeowner doing a DIY remodel of a small bathroom. I am building the vanity myself, and will be installing a surface-mounted vessel sink. I'd like to put a drawer in the vanity just under the top, running the width of the vanity, but the drainpipe (in its current position) kind of gets in the way.

Then I thought that perhaps I could run the drainpipe to the back of the vanity with a horizontal tailpipe, mounted just below the vanity top, and then drop it into the trap at the back of the vanity and out through the wall. Then I could put a drawer just below the tailpipe. The length of the tailpipe would be no more than 12 inches; I think I could use 1.5" PVC for the tailpipe, and 2" for the drop and trap.

Obviously, I don't have much experience with plumbing design, so if anyone who knows more than I do can tell me why this is a really bad idea, I'd be grateful!

Thanks and Merry Xmas,
David

Yes, you can do that. Keep the piping at 1½".

Just be advised, that with that drain and the configuration you describe the sink will probably drain very poorly, even though the drain pipe is not obstructed.

Thank you hj (and everyone else who replied!). Is there anything you could suggest that would improve the drainage but allow me to achieve the design goal I describe?

You could build a drawer with a notch in it. The notch would only have to be deep enough to clear the sinks tailpiece.
