Does it hurt if I use pipe dope on water lines connecting a faucet in a vanity?

While is does not address the "safe" aspect, the following Q/A point out many relevant points on dope and when it is appropriate: diy.stackexchange.com/questions/21117/…. I personally know of no reason why pipe dope can't be used for a vanity - but I've only used tape or just relied of the fittings without.– Nicholas PappasCommented Apr 6, 2016 at 22:04

Pipe dope is for lubrication, rather than sealing, but here's one hypothetical drawback: pipe dope could conseal a flaw in the connection. It would be better to know that the connection was poor before finding out by having the pipe dope fail a week later. With a finely threaded connection I think that the sealing capacity could become prominent, leading to the possibility of a cover-up.– Ben WelbornCommented Apr 7, 2016 at 17:19

no - pipe dope can pretty much be used everywhere. its not necessary though on anything but a thread to thread seal. most vanities nowadays use flexible supply lines that have compression type fittings at either end with a rubber seal in them. its not necessary on that connection at all.
