Faucet Compatibility and Installation
Choosing the right faucet is not just about style — it also has to be compatible with your sink's hole configuration, countertop thickness, and supply line setup. Understanding a few key specifications before purchasing prevents the most common installation problems and ensures the faucet fits and functions correctly from day one.
Faucet Hole Configurations
The number of holes in your sink or countertop determines which faucets are compatible. Most kitchen and bathroom sinks come pre-drilled with one of the following configurations:
Single-Hole (1 Hole)
A single-hole configuration accepts a faucet with a single mounting point — typically a single-handle faucet where the handle and spout are integrated into one unit. Some widespread faucets can also be installed in a single-hole sink using a deck plate that covers the additional holes.
Three-Hole (Widespread or Center-Set)
Three-hole sinks accept either a center-set faucet (where the handles and spout are on a single base) or a true widespread faucet (where the handles and spout are separate pieces). Center-set faucets typically span 4 inches between the outer holes. Widespread faucets span 6 to 16 inches and require the three holes to be individually drilled.
Four-Hole
A four-hole sink has a dedicated hole for a side spray, soap dispenser, or water filtration tap in addition to the three standard faucet holes. The fourth hole can be covered with a deck plate or fitted with an accessory if not needed.
Mounting Types
Deck-Mount
The most common mounting type. The faucet mounts through holes in the sink deck or countertop and is secured from below with mounting hardware. Compatible with undermount, drop-in, and farmhouse sinks.
Wall-Mount
The faucet body mounts to the wall above the sink rather than through the sink deck. Requires in-wall rough-in plumbing at the correct height and spacing. Best planned during new construction or full renovation.
Vessel Sink Faucets
Vessel sinks sit on top of the countertop, raising the basin height. Vessel faucets have a taller spout to clear the elevated rim. The spout height must be matched to the vessel sink height to ensure the water stream reaches the basin center without splashing.
Key Measurements to Check Before Purchasing
- Number of sink holes: Count the pre-drilled holes in your sink or countertop
- Hole spacing (center-to-center): Measure the distance between the outer holes for three-hole configurations
- Countertop thickness: Most faucet shanks accommodate standard countertop thicknesses; verify if you have thick stone or custom countertops
- Spout reach: The spout should extend far enough to center the water stream over the drain
- Spout height: Ensure the spout clears any vessel sink rim or deep basin
- Supply line connections: Most VIGO faucets include supply lines; confirm the connection type matches your shut-off valves (typically 3/8-inch compression)
ADA Compliance and Accessibility
ADA-compliant faucets use a single lever handle that can be operated with one hand without tight grasping, pinching, or twisting. VIGO single-handle kitchen and bathroom faucets meet ADA compliance standards, making them suitable for accessible installations and universal design projects.
Certifications to Look For
- cUPC: Confirms the faucet meets plumbing standards for the US and Canada
- NSF/ANSI 61: Certifies that materials in contact with drinking water are lead-free and safe
- ADA: Confirms single-lever operability for accessible design
- WaterSense (EPA): Certifies flow rates at or below 1.5 GPM for water efficiency
VIGO kitchen and bathroom faucets carry cUPC and NSF/ANSI 61 certifications. ADA compliance is confirmed on single-handle models.
Frequently Asked Questions
How do I know if a faucet will fit my sink?
Count the number of pre-drilled holes in your sink and measure the center-to-center spacing between the outer holes. Match these to the faucet's hole requirements. Single-hole faucets fit one-hole sinks; widespread faucets require three separate holes at the correct spacing.
Can I install a single-hole faucet in a three-hole sink?
Yes. A deck plate (also called an escutcheon) covers the extra holes and allows a single-hole faucet to be installed in a three-hole sink. Many VIGO single-handle faucets include a deck plate for this purpose.
What is the difference between a center-set and widespread faucet?
A center-set faucet has the handles and spout on a single base that spans 4 inches between holes. A widespread faucet has separate handle and spout pieces that can span 6 to 16 inches, allowing more flexibility in placement and a more open look on the sink deck.
Do VIGO faucets include supply lines?
Yes. Most VIGO faucets include braided stainless steel supply lines in the box. Check the product listing to confirm what is included before purchasing additional hardware.
What flow rate do VIGO faucets use?
VIGO kitchen faucets typically flow at 1.8 GPM and bathroom faucets at 1.2 GPM (WaterSense compliant). Exact flow rates vary by model and are listed in the product specifications.
