Measuring for a new bathroom faucet primarily involves determining the spacing between the holes in your sink or countertop. This crucial measurement ensures the faucet you choose will fit correctly.
Key Measurement: Sink Hole Spacing
The most important measurement is the distance between the holes already drilled into your sink or countertop. For sinks with multiple holes (typically two or three), you need to measure the space between the very centers of the farthest-left hole and farthest-right hole drilled into your sink.
Use a tape measure or ruler to find this distance from the exact center of one hole to the exact center of the other.
Understanding Faucet Types and Spacing
Faucet designs are made to align with standard sink hole configurations. Knowing the measured distance between the holes helps you identify the type of faucet you need:
- Centerset Faucets: These are designed for sinks with three holes where the handles and spout are combined on a single baseplate.
- Widespread Faucets: These feature a separate spout and two separate handles, allowing for more flexible spacing between them.
While there is no single standard bathroom faucet size, faucet centers usually range from 4 to 16 inches. This range covers the common faucet types:
| Faucet Type | Typical Hole Spacing (Center-to-Center) |
|---|---|
| Centerset | 4 inches |
| Widespread | 6 to 8 inches (or wider) |
If your sink has only one hole, you will need a single-hole faucet. These faucets typically integrate the handle and spout into one unit or feature a single lever control.
Why This Measurement is Essential
Matching the faucet's "center-to-center" measurement to your sink's hole spacing is fundamental for a successful installation. A faucet designed for a 4-inch centerset won't fit a sink drilled for a 6-inch widespread faucet without modifications (which are often not feasible or desirable).
Other Considerations (Briefly)
While hole spacing is the primary measurement for fitting the faucet base, you might also consider:
- Deck Thickness: The thickness of the countertop or sink deck where the faucet will be installed, to ensure the faucet's mounting hardware is compatible.
- Spout Reach and Height: How far the spout extends into the sink basin and its height, affecting usability and preventing splashing.
Focusing on the center-to-center hole spacing based on your sink's configuration is the most critical step in measuring for your new bathroom faucet.
