We had less than that planned, a Dornbracht single-hole faucet, the seperate matching sprayer and a soap dispenser behind the 30" Rohl. Ditched the soap dispenser as it was way too much. If you have the 36" Rohl it may be a bit better but I couldn't tell until we actually held all the pieces up behind the sink.

Wouldn't it be great if someone imported the Triflow faucet from England which has filtered cold water, instant hot, and regular water all in one faucet.

I have the 30 inch Shaw's, a Perrin Rowe bridge faucet with sprayer and a small filtered water tap. It fits but would look better without the filtered water. No way I can imagine adding anything else.
