You have presented a 500 pound question that has no single answer so I'll give you three 166.66 pound answers. First,you need a deck mount hole in sink,I don't see one. Secound,if you are talking about a vegetable sprayer,they are available with provisions for plumbing directly into suppy tubes and coming through wall same as facuet. Third,if your plumber doesn't know everything I just told you,you have the wrong plumber. The best set up is a commercial facuet with overhead sprayer like used on pre-rinse table before dishes go into automatic washer in restraunts.

@kthark - what did you end up doing? I’m trying to figure out the wall mount faucet/sprayer issue myself!

Well Liz as you can see,kthark dropped by,asked a question and school hopped on down the street without acknowledging my suggestions. After 3 years she's probably in the next county still diddy bopping along without a worry in the world.

@elizabeth_eclectic Wrestling with the same myself! Trying to decide whether to fork out for the Groff G-9935 independent side spray (the only other option seems to be a Watermark at twice the already high price!), or see if my plumber can improvise a way to hook up the Chicago Faucets spoutless faucet (2303-ABCP) to a sprayer attachment. Or just skip the sprayer and use a sponge on the sink.

Have you made a decision?
