12″ to top of arc, 10″ to the bottom of the facet and then add the depth of you sink, 8″ extension. I like mine, but the water flow is lower than some of the others. I think it only puts out 1.5 gallon per minute. So it seems slow to me, some put out 2 gpm. Also the pull out handle is made of plastic, so I went to Loew’s and even the $350.00 ones are also made of plastic handles. But I do like it.
