Can I install a sink sprayer with a bathroom faucet?
The simplest approach to this is likely a second faucet - one of the &quot;modern&quot; faucet-is-the-sprayer that pulls out types would be least intrusive.
Might look a little weird, but to get a mixer and a sprayer (without risking major surgery on your dragon faucet) you're pretty much looking at that or installing a shower valve for the mixer, and that's going to look more weird, I expect.
