Can someone tell me how high off the floor they usually plunb their water suppy lines for both a kitchen sink and a bathroom sink. I was roughing in my drains at 20" off the floor for my bath sink and 14" off the floor for my kitchen sink, do you agree with that also?

12-18" for bath sink with full vanity (if you won't see the plumbing; other vanities/pedestals might do better with higher supplies). Usually you'd match the hight of the supplies to the height of the drain rough ins.

In one of my baths I have the supply and waste pipes roughed in from the floor, so I guess 0-24" could be an answer as well.. :wink:

20" is a little higher than avg. for bath, I think, but if 20" works with your cabinetry and sink depth it's not a problem.

I've heard that 18" is the standard for kitchen sinks. 12-14" is good for a deeper sink w/garbage disposal. The extra clearance couldn't hurt even if you're not planning for deep sink/disposal now.

Code in your area might be more specific (???).
