Replacing bath room sink/faucet with vanity.


I tried without success to replace a misaligned sink drain, I could use the sink but only with the water slightly turned on, otherwise it would leak from the elbow coming up from the chrome p trap.

Now that I removed the sink/vanity there is more room to work with.
The old tailpiece was off to the right of the p trap, where the cold water
shut off valve is in the picture. The hot water shut off valve is closer to the p trap, my question is does the tailpiece have to be between the 2 shut off water valves?

The p trap is still good, everything else will be replaced, water shut off
valves, supply lines, faucet, tailpiece drain,sink, vanity.

The tailpiece can be wherever you want it, provided that the p-trap will hook up to the drain.

I'd pull that galvanized nipple out of there, and thread in either pvc or abs male adapter, then you can use a 1/8 bend to get yourself a little further either direction if you want to.

Besides, that galvanized nipple will eventually rot out on the bottom and leak.

The drain does not have to be between the two pipes. When you are making the connection between the ptrap and the drain in the sink be sure to use Teflon tape or some pipe dope. Good Teflon tape up and a tight connection with prevent leaks.

Also, when I installed a new sink, vanity and faucet in my bathroom I noticed water dripping from ptrap. The water was not leaking from the drain pipe itself, but a poor connection on my part of the drain in the sink itself. Some plumbers putty and Teflon solved the issue.

Depending on the design of your new vanity, the pipes may not align without interference with drawers or cabinet back. Study the back of old vanity and figure how to modify new one.

That is going to be quite a challenge pulling that galvanized nipple
sticking out from the wall. How do I go about this?
Removing the p-trap wasn't easy but I got it off last time.
The bathroom was done in 1988. That is the original p trap
the end of the tailpiece had rotted/rusted and was leaking from
above the trap. I had what they call a NY style p trap.

It's ok then to use pvc or abs male adapter into a chrome p trap right?

I have a couple of things to do first before I get involved in this, I need
to have the tub re-grouted along with some tiles on the wall, re glaze the tub, upgrade bath vent fan.

Yes, that is true. I don't need drawers and the back has to be thin, this
wasn't an issue with the old vanity, just need the vanity to store small
stuff like soap, shampoo,shaving creams, razors. I have a medicine
cabinet with mirror on the wall.

The old vanity measured "19(W) X "31(H) X "16 1/4(D)...I can go slightly
higher and wider with the new vanity.

Not trying to be a smart-asz but it would be quite a challenge to pull that nipple from the wall. So get a pipe wrench and "unscrew" it. Doesn't look too bad. And then like Alan said get a PVC male adaptor.
