I’ve got three plumbing books and none of them says what a typical kitchen sink drain and supply rough-in should be. They all give rough-ins for bathroom vanities, but nothing for kitchen sinks.
I went to HD and Lowe’s this evening, but the books there were useless. I was looking for that taunton one recommended in another thread recently, but no luck…just Stanley and Black and Decker drivel.
I’ve got to install a kitchen sink drain rough-in tomorrow. This is for a sink without garbage disposal. Something in the back of my head says 18-19 inches. Is that correct?

I'm not sure what it should be, but I just measured mine here at home and it is 18".
Before recommeding any books I would suggest talking to experienced tradesmen first. Books can give you a starting point but they are no substitute for real, on the job expertise. That being said the 'for pros, by pros' series are a good reference. Rex Cauldwell lays out the entire plumbing process.

What if they want to have a disposer in the future, or an extra deep sink?
We generally put our stub out elevations at 16" for kitchen sinks.
Yes sometimes if there isn't a disposer, & it's a shallow sink can mean a longer tailpiece, but that beats having to open the back or the cab & lowering the rough-in.
