Can Wall Mount Faucet Be Used With Undermount Sink
When designing a sleek, functional, and modern bathroom, many homeowners and designers pair an undermount sink with a wall mount faucet. This combination creates a clean, minimalist look — but it raises a common question: can a wall mount faucet really be used with an undermount sink?
The answer is yes, and it’s an increasingly popular choice for both residential and commercial bathrooms. With proper planning, alignment, and installation, a wall-mounted faucet can pair beautifully with an undermount sink, enhancing both the aesthetic and practicality of your vanity area.
As a professional manufacturer of precision-engineered sanitary ware, Topshine offers wall-mounted faucets designed for seamless installation with various sink types, including undermount basins.
1. Understanding the Two Fixtures
a) Wall Mount Faucet
A wall mount faucet is installed directly on the wall above the sink rather than on the countertop. The water pipes are concealed inside the wall, resulting in a clean, open surface.
b) Undermount Sink
An undermount sink is installed beneath the countertop, leaving the counter surface smooth and uninterrupted. It provides a streamlined appearance and makes cleaning easier by eliminating exposed sink rims.
When used together, they create an uncluttered, sophisticated design — ideal for modern bathrooms and minimalist interiors.
2. Why Wall Mount Faucets Work Well With Undermount Sinks
a) Clean and Minimal Appearance
Since neither the faucet nor the sink sits above the countertop, this combination gives a floating effect. The visual continuity between the wall, counter, and sink enhances the feeling of space and simplicity.
Topshine’s wall-mounted faucets are designed with slim profiles and precise spout angles to match the smooth lines of undermount basins.
b) Easier Cleaning and Maintenance
Without deck-mounted holes or sink rims, you can easily wipe water and soap residue straight into the sink. There are fewer edges for mold or limescale to build up, keeping your vanity area spotless.
c) Flexible Countertop Design
You can choose any countertop material — stone, marble, quartz, or solid surface — without needing faucet holes. This allows more creative freedom in layout and finish selection.
d) Space Efficiency
Wall-mounted faucets free up valuable counter space, leaving room for toiletries or decorative items. This is particularly useful for compact bathrooms.
3. Key Considerations Before Installation
While the pairing works beautifully, several important factors must be addressed during design and installation.
a) Proper Faucet Height
The faucet outlet should be positioned 8–10 inches (200–250 mm) above the sink rim to allow comfortable clearance and prevent splashing.
Measure from the top edge of the undermount sink (not the countertop) to the bottom of the faucet spout.
b) Spout Reach
The faucet spout should extend far enough for the water stream to hit the center of the sink bowl.
Typically, a 6–8 inch (150–200 mm) spout reach works best for standard undermount basins.
Topshine faucets come in various spout lengths to suit different sink depths and designs.
c) Wall Thickness and Plumbing
Ensure your wall can accommodate the faucet’s rough-in valve. Standard in-wall depth is 2–3 inches, but thicker walls may require extension kits. Proper alignment of hot and cold water inlets (usually 150 mm apart) is essential.
d) Backsplash Protection
Even though undermount sinks minimize water splashes, a tile or waterproof backsplash behind the faucet helps protect the wall surface from moisture damage.
e) Professional Installation
Wall-mounted faucets require accurate plumbing and alignment. Hiring a professional installer ensures correct positioning and leak-free performance.
4. Installation Tips for a Perfect Fit
Follow these general steps for proper installation:
Turn off water supply before installation.
Mark faucet position on the wall — ensure height and reach align with the sink center.
Install the valve body inside the wall and connect hot/cold water lines.
Finish wall tiling, leaving the valve outlet accessible.
Attach spout and handles once the wall is complete.
Test for leaks and adjust water pressure before sealing edges.
Topshine provides detailed installation diagrams with all wall-mount faucets, simplifying this process for both homeowners and contractors.
5. Design and Style Advantages
Pairing an undermount sink with a wall-mounted faucet offers several design advantages:
Luxury Appearance: Creates a floating, hotel-style vanity aesthetic.
Custom Countertop Options: Works perfectly with stone or solid-surface counters.
Versatile Finishes: Choose from chrome, brushed nickel, matte black, or gold to match the sink and décor.
Ideal for Double Vanities: Wall-mounted faucets can be aligned symmetrically for a balanced look.
Topshine’s faucet collection includes both single-handle and dual-handle models to fit different bathroom layouts and preferences.
6. Common Mistakes to Avoid
Incorrect Height: If installed too high, water will splash outside the sink. Too low, and it becomes uncomfortable to use.
Misaligned Centerline: The faucet spout must align precisely with the sink drain.
Ignoring Wall Thickness: Not accounting for tile or drywall depth can lead to valve misalignment.
Skipping Waterproofing: Always seal behind and around the faucet to prevent wall moisture damage.
Avoiding these mistakes ensures professional-grade results and long-lasting functionality.
7. Maintenance and Care
To keep your wall-mounted faucet and undermount sink combination in top condition:
Wipe dry after each use to prevent water spots.
Clean with mild soap and soft cloths; avoid harsh chemicals.
Check seals annually for signs of wear or leaks.
Clean aerators periodically to maintain smooth water flow.
Topshine’s corrosion-resistant finishes and ceramic valve technology ensure long-term durability and easy maintenance.
