Whether you do a sidesplash or not, I absolutely agree with pamelah that the solid backsplash is the way to go (rather than tile). Honestly, I prefer to go without sidesplash in general. However, if you feel like the sidesplash is important (either functionally or visually), I think what they are proposing looks just fine, not like a mistake at all. My vote would first be to go with just the backsplash (no sidesplash) with the curved design symmetrical on both sides. My next choice would be to go with exactly what is in your drawing. I think either choice would be lovely and will just depend on your visual preference and functional needs. Regardless, your vanities are beautiful and your countertops are stunning!

The only thing I can think of is this stuff. It would likely need to be reapplied periodically if it worked. Here is a link that might be useful: Rub-n-buff

I just bit the bullet, after much searching and agonizing, and got the P&R bridge. The main difference for me was that I wanted the side spray and 2 legs. The Rohl Country with side spray is 3 leg as opposed to the P&R which is the 2 leg style I prefer. The finish changes the price a lot, I went with chrome for $1200 (satin nickel would have added $400!) The only other company I found that made a 2 leg bridge faucet with side spray was Newport Brass, but I was dissuaded by the plumber (leak issues) and told that cost was similar (tho you can find Newport on line about $700). Also consider Grohe Bridgeport for a 3 leg bridge w/spray at about $800. Other on line sites I found good prices for P and R were amazon and vintagetub, if you feel comfortable ordering on line. I think you can't go wrong with Rohl or P and R - very high quality faucets. Here is a link that might be useful: Newport Brass Bridge w/spray

I recently (as in this week!) was asking myself the same exact question - a quick look at all my kitchen magazines convinced me that the satin nickel faucet/stainless sink/ ORB hardware combo is done all the time. I think it's a great look. The faucet will pick up on the sink, your Wolf range, and any other stainless appliances you may have. Like you I have creamy cabinets with glaze( with a cherry island) , Wolf SS range, paneled fridge and SS undermount sinks. My granite is in the medium brown tones - New Venetian Gold. I'm doing ORB hardware on both perimeter and island, satin nickel faucets and stainless undermount sinks. Lighting will probably have ORB or similar trim. I've also seen ORB faucets matched up to ORB hardware , including mixed with stainless sinks (one like that right on the cover of one of a recent kitchen magazine) - those can be just gorgeous , too. To me, some faucets styles look better in the ORB than others - just personal preference. In addition to kitchen magazines, you might also want to check out the finished kitchen blog on this site - look at categories and then creamy colored kitchens or ORB. If you want a satin nickel faucet though, I think you'll be reassured by what you see.
