Is there a standard height off the floor for the cold/hot water supplies and the waste pipe or drain (the part the P trap goes into).

I ripped out what was there before as the sink was a long distance from the waste pipe (terminoloy?) and the pitch was towards the sink and not the drain.

I was thinking about 19" off the finished floor for the supplies and 12" for the drain?

The kitchen sink will be an undermount either 9 or 10" deep.

Thanks
