My waste pipe almost touches the bottom of my cabinet! Only about 1" clearance. My sink cab has a drawer underneath so the cabinet sits higher than most.

I'm at work right now but if I gave my best guesstimate I would say 10-12 inches. That's from the hole in the wall to the floor.

From the center it's 10 3/4 inches down to the floor. HTH!

Thanks everyone!

Are you talking about the floor of the cabinet or the actual floor of the kitchen in your measurements? tracyac and angier - would you please clarify?

I greatly appreciate you taking the measurements. The center of our waste drain is 10" from the floor of the sink base cabinet and the floor of the cabinet is another 6" from the slab floor. So . . . . , I don't think the super single is going to work unless I lower the waste drain at least 4 or more inches and I understand that is a big job.

Our sink cabinet is along a pony wall that also has the DW. We are in a great room design and the kitchen is open to the living and dining room. I think the piping would be fairly easy to get to from the dining room side of the pony wall, but I don't know if the waste pipe travels somewhere else before it goes below our slab. If it were a straight drop from where the stub comes out of the cabinet perhaps the job wouldn't be too bad. Hum m m m ?

Thanks again for the help!
