Yours is a pretty popular sink design currently for a two-bowl type. Generally this type sink is referred to here as a 1-3/4 sink. I love mine and it has the same dimensions (same depth of sinks) as yours.

As far as space between the faucet and backsplash...just make sure the faucet design you picked out has enough room to operate the on/off handle without it hitting the backsplash and without you scraping your knuckles as you work it. HD or fabricator/intallers should able to tell you if it will work.

Fabricator said i will need to have the lever on top of the faucet. Not good to have lever on the side.

He no doubt knows what will fit in the space you have. Take a look at the faucet specs if you've already bought a side handle faucet to double check...those specs will say how much room operating a side-handle faucet requires. There are plenty of nice looking faucets with the handle on top too.

I am going to redo my kitchen and use a Rohl farmhouse sink with Rohl faucets. I saw this set up at a designer showroom and 8 inches was left for the faucets. Seems a bit extravagant but it looked good and sure would make cleaning behind the faucets easy. My friend's faucet is so close to her backsplash that she can hardly get her hand behind the faucets to clean.

springwater - my bathroom faucet is like that; i hate it. it is one of the things that helped me decide to avoid the 4" granite backsplash and just have tile -- that should free up a whole half inch. :) i think the problem is the undermount sink - the exterior of the sink is larger than the bowl and the faucet hole has to be drilled behind it. my other bathroom vanity, which has integrated corian sink, has the faucet closer to the bowl with more room behind it.
