i need to know, what is "standard" stub-in (roughed in) heights for vanity drain and water supply. :confused:
Every plumber has his own "standard" height, and even those may be changed if the conditions in the wall require it.

You can rough-in the lav waste at:
18" for 30" counter
20" for 32 counter
Water supply can be roughed at the same level.
Most of the time, I use a strip bar to hold the stub outs and set the supplies slightly higher than the waste line.
