The Kohler Brockway is predrilled for 3" vertical faucets & the Kohler Bannon/Amercian Standard Akron/Lakewell sinks are predrilled for 8" centered faucets. Find a wall mounted 8" or 3" centered faucet & cross your fingers they fit together nicely. Also, make sure the faucet depth (from backsplash to faucet front) isn't too long. Some of these service sinks are also offered w/blank backs (no holes) so you could potentially find any wall-mounted faucet you like & place it above the splash (it may look odd?) - just keep in mind height of faucet to basin for splash.
