Bathroom Faucet Spacing
What is the ideal widespread faucet spacing in a bathroom. We are using Kohler Caxton 2210 sinks (17x14) and I thought typical spacing for three hole faucets was 8 inches (total, center to center from the left handle to right handle). My marble fabricator is saying they typically drill holes for spacing of 12 inches which seems too large to me. What is ideal, any thoughts? Also, should faucets follow the curve of the sink? Any advice is greatly appreciated.
