Installing a wall mount faucet is one of the best ways to create a clean, modern, and space-saving look in your bathroom or kitchen. Compared to deck-mounted faucets, wall-mounted designs offer a sleek aesthetic and practical benefits such as easier cleaning and more countertop space. However, proper installation requires accuracy and understanding of plumbing structure behind the wall. This guide explains in detail how to install a wall mount faucet step-by-step, what tools you need, and why HAOJIAJIA’s concealed Basin Faucet is an ideal choice for your project.
Before starting the installation, it’s essential to understand how wall-mounted faucets are built and how they function within your plumbing system.
A wall mount faucet is attached directly to the wall instead of the sink or countertop. It features a concealed valve body hidden inside the wall and a visible spout and handles on the outer surface. This design keeps the plumbing system out of sight, giving your bathroom a minimalist and modern appearance.
| Advantage | Description |
|---|---|
| Space Efficiency | Keeps the sink area clean and provides more counter space for toiletries or accessories. |
| Aesthetic Appeal | Adds a contemporary, luxury touch to bathrooms and washrooms. |
| Easy Cleaning | No water pooling around the base, reducing mold buildup and simplifying maintenance. |
| Flexible Sink Design | Compatible with vessel basins, wall-hung sinks, and countertop bowls. |
HAOJIAJIA’s concealed basin faucet integrates all necessary internal components to ensure smooth water flow and leak-free performance. The structure includes:
Concealed valve box – Houses the internal plumbing and mixing valve.
Hot and cold water inlets – Connect to supply lines within the wall.
Spout – Extends from the wall into the basin.
Handle(s) – Control temperature and flow rate.
This design ensures that only the elegant exterior components are visible while all plumbing connections remain hidden.
Proper preparation determines the success of a wall mount faucet installation. Take time to measure, mark, and plan before cutting or connecting any pipes.
| Category | Items |
|---|---|
| Tools | Adjustable wrench, pipe cutter, screwdriver, measuring tape, level, drill, and Teflon tape. |
| Materials | Wall mount faucet kit, water supply lines, concealed valve box, wall anchors, and plumber’s putty. |
Wall Thickness: Ensure your wall is thick enough to house the concealed valve body (usually at least 75–100 mm).
Pipe Access: You’ll need access to both hot and cold water supply lines behind the wall.
Structural Strength: Reinforce drywall or light partitions with wooden backing or cement board before mounting heavy fixtures.
For bathrooms:
Recommended height above the basin rim: 20–25 cm (8–10 inches).
Ensure water stream falls centrally into the sink to prevent splashing.
For kitchens:
Maintain sufficient clearance for large pots or containers under the faucet.
Before any plumbing work, turn off the main water supply and open a nearby faucet to release residual pressure.
Installing a wall mount faucet involves careful alignment and secure connection of the concealed valve inside the wall. Below are detailed steps:
Mark Faucet Centerline: Use a level to draw a horizontal line at the desired faucet height.
Mark Valve Position: Place the valve box template on the wall and mark openings for the spout and handle(s).
Cut Wall Openings: Use a drill or hole saw to create openings for water pipes and valve housing.
Fix Position: Secure the concealed box to the wall frame using brackets or wall anchors.
Align Accurately: The front face of the valve box should be flush with the finished wall surface.
Check Level: Use a spirit level to ensure perfect horizontal alignment before tightening screws.
Connect Hot and Cold Inlets: Attach water supply lines using Teflon tape to prevent leaks. Hot water is typically on the left, cold on the right.
Before covering the wall, perform a pressure test to check for leaks.
Turn on the water supply briefly and check all connections.
If leaks are detected, tighten joints or reapply Teflon tape.
Only proceed once the system is 100% leak-free.
Seal the Opening: Once tested, cover the valve box with tile, marble, or waterproof wall panels.
Leave Access Holes: The spout and handle openings must remain accessible.
Ensure Level Surface: Smooth the finishing material to prevent gaps around the trim plate.
Attach Decorative Plate: Align and press the trim plate onto the concealed box.
Mount Faucet Spout: Screw the spout onto the outlet and tighten carefully with a wrench.
Install Handles: Connect the handles or control levers onto the valve stems.
Check Function: Turn on the water to verify smooth operation of temperature and flow control.
Even after proper installation, maintaining a wall mount faucet is essential to ensure long-term reliability and performance.
| Maintenance Task | Frequency | Description |
|---|---|---|
| Clean the Aerator | Monthly | Remove debris and lime buildup from the spout aerator to maintain water pressure. |
| Inspect Seals | Every 6 months | Check O-rings and cartridge seals for wear to prevent leaks. |
| Polish the Surface | Weekly | Wipe with soft cloth and mild cleaner to preserve shine and prevent corrosion. |
| Flush Valves | As needed | If flow decreases, flush out sediment from pipes or valve body. |
Incorrect Height Placement: Misaligned faucets can cause splashing or poor reach into the basin.
Loose Connections: Always use sealing tape and verify tightness before wall closure.
Skipping Pressure Test: Testing before sealing the wall prevents expensive rework later.
Ignoring Wall Thickness: Ensure valve box fits flush with the final wall surface to avoid gaps or misalignment.
