Direct answer: Centerset and widespread describe different bathroom faucet mounting arrangements. The label alone does not guarantee fit: measure hole count and center spacing on your vanity, then compare the exact faucet’s permitted spread, deck limits and handle clearance. A nominal “4-inch” or “8-inch” phrase should lead to a measurement, not replace one.


Understand the two arrangements
A centerset faucet commonly combines spout and handles on a compact base intended for a close three-hole pattern. A widespread configuration separates the handles and spout, allowing the trim pieces to be set apart within the model’s allowed range. Product designs vary; verify the actual drawing rather than relying on a category definition.
Kohler’s bathroom faucet listings and VIGO’s widespread guide illustrate that configurations are product-specific. These references explain terminology, not the compatibility of every Pelican or Cavalieri-listed faucet.
Measure center-to-center, not the outside span
Count holes, then measure from the center of the left opening to the center of the right opening. Record the distance between any center spout hole and handle holes too. The overall faucet trim width is not the same as mounting-hole spacing.
Also record sink/basin location, deck depth, backsplash distance, handle sweep and available space for soap or accessories. If holes are already drilled, the candidate faucet’s specified range must include the measured spacing.
Check the vanity deck and the bowl
Measure countertop thickness and confirm the faucet’s mounting limits. The spout must project into the basin in a useful location; a tall spout over a shallow bowl may increase splash, while a short reach can place water near the back wall. Verify actual spout height and reach on the chosen model.
For a replacement, keep track of escutcheon/base coverage around existing holes. A faucet may attach correctly but leave unused openings visible. A deck plate or separate trim is only a solution if exact dimensions and included components support it.
Fill in the pre-order worksheet
| Vanity detail | Measure / inspect | Match to product sheet |
|---|---|---|
| Hole count | _____ | Faucet mounting pattern |
| Handle-hole centers | _____ in. | Permitted spread |
| Deck thickness | _____ in. | Mounting thickness range |
| Basin clearance | Height / reach / bowl position | Spout dimensions |
| Back clearance | _____ in. | Handle movement and backsplash |
Example: if centers measure approximately 4 inches apart, compare that exact measurement with the model’s center configuration and install sheet. Do not select a faucet based on “4-inch” in a product title alone.
Shop the layout you actually have
Browse bathroom faucets, recording each product’s actual spread and mounting details. If vanity replacement is planned, select basin and faucet together; if the existing vanity remains, use the drilled deck as a constraint rather than assuming it can be changed.
Before ordering, check deck thickness, supply connection, spout dimensions, included hardware and return terms. Contact Cavalieri sales at 321-424-0546 with the product model for catalog questions; faucet installation is not promised with the online sale.
Avoid drilling until the faucet is chosen
If the vanity top is being replaced or newly fabricated, obtain the faucet model before holes are drilled. Provide the fabricator with the manufacturer’s template and the intended handle placement; do not translate a “4-inch” or “8-inch” label into a drilling instruction without checking the drawing. If a medicine cabinet or side wall sits close to the basin, test the handle arc on a paper mock-up. That planning step can reveal a clearance problem before the countertop becomes permanent. Keep the faucet box and installation sheet until the final mounting arrangement is confirmed.
Compare actual Cavalieri models before ordering
Open these current catalog model pages to compare the available options and product documents. A model appearing here is not a guarantee that it fits your cabinet, countertop or plumbing. Confirm the exact model, selected finish, included parts and installation drawing before placing an order.

Frequently Asked Questions
What is the difference between centerset and widespread faucets?
Centerset faucets use a compact combined arrangement; widespread faucets separate handles and spout. Product dimensions and allowed spacing vary, so check the exact drawing.
How do I tell whether my bathroom faucet is 4-inch or 8-inch?
Measure center-to-center between the outer mounting holes. Compare that measurement and the hole layout with the faucet’s installation instructions.
Can I replace a centerset faucet with a widespread faucet?
Only if the vanity has a compatible hole pattern or can be modified appropriately. Check the countertop, hole positions and exact model template before buying.
Does an 8-inch widespread faucet fit any three-hole sink?
No. Hole count alone does not establish fit; center spacing, deck thickness, handle clearance and spout alignment matter.
Can a deck plate hide unused vanity holes?
Sometimes, but only when the faucet’s compatible plate covers the openings and the mounting pattern works. Verify plate dimensions and whether it is included.
