Have chosen Toto Soiree single-handled faucets (TL960SD) and narrowed down the sink choices to Toto LT191(G) or Kohler Kelston (K-2382). Both sinks are shallow, rectangular, and undermounted. However, spec sheet for Toto sink says it's not recommended for use with the Soiree faucet. (I've emailed Toto for explanation, haven't yet heard back.)
I'm guessing for a shallow sink, it's wise to have a low spout to minimize splashing. Beyond that, what other factors are involved in determining compatibility? Where the drain hole is? The pop-up mechanism? What am I missing?
