Rough-in Height for Kitchen Supply Lines?


My house is built on a slab and has been replumbed through the attic with CPVC because of a slab leak prior to my ownership.

I am remodeling the kitchen and the hot/cold supply will enter the sink base from the back of the cabinet. I plan to install an under-counter mounted deep sink, which I have not yet purchased.

I'm not sure what height (measured from the finished floor) to place the hot/cold supplies? I've read that 18" to 20" is the standard but I've also read this is an old standard and can be too high for today's deeper sinks.

I don't want the supplies to interfere with the sink or the disposal but I also don't want to place them too low.

Any advice is appreciated.

TIA.

Tipsy

You should be OK with 18". Your counter top is 36". That means your sink needs to be 18" deep to interfere. More important is the roughin height of your waste pipe. To high and your sunk. Best to choose a sink depth including disposal and pipe accordingly.

Thanks...the original drain stack is still in the slab.

I can't recall how tall it is at the moment but I suppose it can be cut down a bit if need be.

Rough them at 18" that will cover most anything
