heights for supply and drain lines for bathroom sink

[Steve_P]

33" high bathroom sink/cabinet combo. What should the heights for the supply lines and drain be above the floor where they exit the wall? Thanks!

21" works, plus or minus for a 33" counter

For a 30" counter, 18"
The water can be higher then the drain.

thanks
one more question: once the cabinet is in and you trim back the stubs for the supply to put on the shut off valves, how far from the inside wall of the cabinet to you cut?

I realize the answers for these questions will vary depending on who answers, just looking for opinions.

I allow room for an escutcheon, the shutoff and about 1/4" between.
You can have them farther out too.
For a quick measurement, I put the cutter on the pipe and put my finger between the wall and the handle of the cutter.
I have no idea what distance that is, but it works for me.

The drain is determined by location of the drain on the sink or lav.

I use a rule of thumb, From end of my thumb to my first knuckle about 1 1/4 inches for anglestops

I put the drain between 17" and 19". The waters at 21". I eyeball the stubs at about 1 1/2" from the back of the cabinet.
