Question: 1 / 400

What is the required inch spread for a 3-hole lavatory faucet setup?

2 inches

4 inches

The required inch spread for a 3-hole lavatory faucet setup is 4 inches. This measurement is crucial for ensuring that the faucet properly fits the sink and aligns with the pre-drilled holes. A 4-inch spread indicates that the distance from the center of the hot water handle to the center of the cold water handle is 4 inches, which is a standard size for many lavatory faucets designed for single sink applications. This configuration allows for a compact design that fits well in smaller bathrooms or spaces where a full spread faucet might be too large.

Other common spreads include 6 inches and 8 inches, which are typically used in more extensive setups or different faucets designed for larger sinks. However, the 4-inch spread is specifically designed for smaller, commonly found lavatory sink configurations, making it the standard answer for a 3-hole faucet setup in this context.
