Unlike deck-mounted faucets, wall-mounted faucets do not pass through the sink itself. Instead, all functional components—water lines, fittings, and structural supports—are located behind the wall. This design creates the clean, minimalist look often favored in modern bathrooms. Manufacturers such as EMYSA design Concealed Shower Mixers and wall-mounted fixtures with the same principle: the visible part remains sleek while the working parts remain hidden inside the wall. Understanding what does and does not pass through the sink helps ensure proper planning during installation.
A key distinction is that the sink plays no structural role in supporting or connecting a wall-mounted faucet.
No faucet shanks
No water supply hoses
No escutcheons or mounting hardware
No handle assemblies
The sink bowl sits completely separate from the faucet’s plumbing. This is similar to EMYSA’s concealed systems, where fixtures appear minimal from the outside but rely on internal engineering for support and performance.
All installation components for a wall-mounted faucet are located in the wall cavity.
Hot and cold water supply lines
Elbows or mounting plates that secure the valve body
Concealed mixer or internal brass structure
Threaded connections for the faucet body
Sealing components and support materials
This mirrors the concealed mechanisms inside EMYSA’s stainless steel and brass shower mixers, where internal bodies control water flow behind the wall while only the trim and handle remain visible.
Because the faucet is installed above and independent from the sink, the bowl serves only as the water-catching surface.
Catching and directing water to the drain
Providing ergonomic alignment with the spout reach
Influencing splash control depending on depth and shape
Manufacturers such as EMYSA design wall-mounted fixtures to provide controlled water flow, making correct spout projection essential for coordination with the sink.
Although the faucet does not pass through the sink, accurate sink measurements ensure proper functionality.
Sink depth to control splash
Sink width to align with faucet centerline
Distance from wall to bowl center to match spout projection
Height of sink rim to determine spout placement
These calculations are similar to the precision required for installing EMYSA’s concealed mixers, where height, depth, and alignment ensure reliable operation.
Because nothing passes through the sink, positioning becomes essential.
The spout should sit 20–30 cm above the sink rim.
The water stream should land near the drain for minimal splash.
The faucet must be centered with the sink bowl.
This design approach parallels EMYSA’s shower system engineering, where water delivery and ergonomic height are carefully calibrated for user comfort.
While nothing penetrates the sink, certain components interact closely with it.
The faucet spout above the basin
The handle or lever trim plate
The escutcheon covering the wall opening
Optional Hand Shower attachments (depending on faucet model)
These components are mounted on the wall surface, not through the sink itself, creating the streamlined look associated with modern bath design.
Incorrect assumptions during bathroom planning can lead to major layout problems.
Mismatched spout reach
Incorrect faucet height
Splash problems due to improper sink depth
Inaccurate rough-in plumbing behind the wall
Following the correct principles—much like EMYSA’s concealed installation approach—ensures long-term performance and visual consistency.
A simple rule applies:
All plumbing and structural components pass through the wall, not the sink.
The sink only receives the water and influences the faucet height and reach.
This knowledge is crucial for architects, remodelers, and homeowners planning a wall-mounted installation, helping them coordinate sink geometry with faucet specifications.
