The concealed thermostatic shower set is a high-end bathroom system featuring a built-in installation design and a precision thermostatic mixing valve that ensures stable water temperature during showers. This system typically includes a concealed thermostatic valve, a rain shower head, a handheld shower, and a control panel, all designed with a modern minimalist aesthetic. Produced by Chinese faucet factories, concealed thermostatic shower sets are made of high-quality brass or stainless steel, offering corrosion resistance, high-temperature tolerance, and long-term durability, making them suitable for both residential and commercial bathrooms.
I Pre-Installation Notes
1. Confirm that the wall structure is suitable for concealed installation (solid concrete or brick walls are ideal).
2. Check if all components are included (e.g., valve body, shower brackets, sealing gaskets).
3. Ensure pre-installed water pipes meet pressure requirements (typically 0.1-0.5MPa).
II Required Tools
– Level gauge
– Electric drill (with tile drill bit)
– Wrench, screwdriver
– Waterproof tape (PTFE tape)
– Measuring tape
III Preparation Steps
1. Turn off the water supply and drain residual water from pipes.
2. Determine installation height (rain shower: 2-2.2m from the floor; control panel: 1.1-1.2m).
3. Mark pipe and valve positions on the wall, ensuring level alignment.
IV Standard Installation Process
1. Embed the Valve Body**: Secure the mixing valve to pre-installed pipes, using a level to ensure alignment.
2. Connect Water Pipes: Attach cold/hot water pipes to corresponding valve ports (blue/red), sealing with PTFE tape.
3. Install Panel & Shower Heads**: Fix the control panel, connect shower heads, and check thread tightness.
4. Seal the Wall: Fill gaps with waterproof material, then cover with tiles or decorative panels.
V Testing & Inspection
1. Check for leaks after water supply is restored.
2. Test thermostatic function: Set to 38°C and observe stability.
3. Switch between shower modes to ensure smooth water flow.
VI Common Issues & Solutions
– Issue 1: Unstable water temperature
Solution: Verify correct pipe connections and balanced water pressure.
– Issue 2: Wall seepage
Solution: Re-seal around the valve body to ensure waterproofing.
– Issue 3: Uneven water flow
Solution: Clean the filter to remove blockages.
VII Safety Tips & Maintenance
1. Do not disassemble the valve core—contact professionals for repairs.
2. Clean shower nozzles regularly to prevent limescale buildup.
3. If unused for long periods, shut off the water supply and drain residual water.
Chinese faucet factories recommend professional installation for optimal performance. Keep the manual for future reference and warranty claims.
