How To Measure for Wall Mount Faucet
Why Proper Measurement Matters
Measuring correctly for a wall mount faucet ensures smooth installation, prevents leakage, avoids misalignment with the sink or basin, and guarantees the faucet’s handles and spout are positioned comfortably for daily use. A small measuring mistake can lead to expensive wall rework or plumbing adjustments, especially for concealed faucet systems like those offered by professional manufacturers such as FUNJAY.
Common Problems Caused by Wrong Measurements
Spout too short or too long
Faucet installed too high or too low
Valve outlets misaligned with faucet body
Splashing issues due to improper height
Reinstallation required after tiling
Measure the Center-to-Center Distance
This is the most critical measurement when selecting a wall mount faucet.
What Is Center-to-Center Distance?
It is the distance between the hot and cold water inlet centers that come out of the wall.
How To Measure
Locate the two plumbing outlets inside the wall.
Use a tape measure to measure the distance from the center of one outlet to the center of the other.
Record the measurement in millimeters or inches.
Standard Sizes
6 inches (150 mm) – most common
8 inches (203 mm) – for larger faucets
Custom / adjustable – some modern concealed valves allow ±20 mm adjustment
Why This Matters
The faucet body must match the exact spacing to avoid installation stress and leaks.
Measure the Faucet Height From the Sink
Spout height determines comfort and splash control.
How To Measure Correct Height
Measure from the top edge of the sink to the intended spout outlet point.
Recommended spout height:
8–12 inches (200–300 mm) above sink rim for general use
Lower height for shallow basins
Higher height for vessel sinks
Factors to Consider
Depth of your sink
Splash distance
User comfort and handwashing angle
Measure the Required Spout Reach
Spout reach = how far the water outlet extends horizontally over the basin.
How To Measure
Measure from the wall surface to the center of the drain hole.
Add 1–2 inches to ensure water falls into the central area.
Ideal Spout Reach
Typically 6–8 inches (150–200 mm)
Must reach over the center of the sink bowl
Why It Matters
Too short → water hits the basin edge
Too long → unnecessary splash and discomfort
Measure the Valve Depth Inside the Wall
Concealed valves (FUNJAY specializes in these) have a required installation depth.
How To Measure Depth
Measure wall cavity thickness before tiling.
Check faucet manufacturer’s “rough-in depth” requirement.
Adjust using mounting brackets if needed.
Standard Rough-In Depth
60–80 mm (some models offer adjustment)
Why This Matters
Incorrect depth causes:
Handles sticking out too far
Valve buried too deep behind tiles
Check Wall Thickness and Pipe Compatibility
Many wall mount faucets require enough internal space for the valve body.
Measurement Steps
Measure the total wall thickness.
Confirm pipe connections (½" NPT or G1/2).
Ensure the concealed valve will fit easily.
Installation Note
Thinner partition walls may require a compact concealed valve model.
Confirm Handle Clearance
Handles must turn freely without hitting the wall or accessories.
How To Measure
Note handle length.
Ensure at least 1.5–2 inches clearance around each handle.
Check vertical clearance if using lever handles.
Why It Matters
Improper clearance leads to:
Scratching walls
Restricted movement
Wear problems over time
Measure After Tiling (Final Check)
Tile thickness affects final valve depth and spacing.
Checklist
Re-measure center-to-center distance
Recheck spout height from finished tile
Verify handle rotation range
Confirm exposed trim will sit flush
Why Do This Step
Prevents problems that occur due to tile thickness or uneven wall surfaces.
Tools You Need for Accurate Measurement
Tape measure
Level
Pencil or marker
Installation manual
Cardboard mockup (optional)
Helpful Tip
Mark reference lines directly on the wall to visualize final faucet position.
Conclusion
Measuring for a wall mount faucet requires careful attention to center-to-center distance, spout height, spout reach, valve rough-in depth, wall thickness, and handle clearance. Following these steps ensures a perfect fit, prevents installation issues, and guarantees a functional, aesthetically pleasing result.
For concealed wall-mount faucet systems, choosing a reliable manufacturer like FUNJAY—who provides accurate technical drawings and adjustable installation designs—helps streamline installation and reduces errors.
