We are in the process of remodeling our kitchen and are trying to narrow in on our sink for our new granite counters. We like the Kohler Staccato with unequal bowls and would like to have it undermount. However, there is a HUGE difference in price: drop-in is $250 vs. undercounter is $630. I know that there are some differences between the two, but not $380 worth, and if anything, the undercounter probably has less metal. I'm sure it is a premium tax for the undercounter option.
I ran across this post that mentions that they used converted a drop-in to undermount.
Does anyone know what is involved with that type of change? What are the things I need to be aware of?
