Concealed Thermostatic Bath Shower Mixer Set Wall Mount Trim Kit Volume Control Diverter Chrome Matt

This concealed thermostatic bath shower mixer trim set is the finishing layer of a professional rough-in valve system, delivering precise water temperature control from behind the wall. The chrome matt faceplate has a soft, satin appearance that resists fingerprints, and the solid metal levers operate the integrated volume control and three-way diverter with a reassuring click.

The thermostatic element reacts instantly to pressure changes elsewhere in the house, holding the selected temperature steady so nobody is surprised by a sudden rush of hot water. A factory-set 38°C safety limit protects children and the elderly, while an override allows higher temperatures when an adult deliberately adjusts it.

• Anti-Scald Thermostat: The element maintains water temperature within ±2°C even when supply pressure fluctuates.
• 38°C Safety Limit: A built-in stop holds the default maximum at 38°C, with a deliberate override for hotter settings.
• Volume Control: An independent lever regulates flow without changing the temperature setting, saving water while you lather or soap.
• Three-Way Diverter: Route water to an overhead shower, hand shower, or tub spout with a single turn of the diverter lever.
• Chrome Matt Faceplate: The satin finish hides water marks and cleans quickly, keeping the wall area looking fresh.
• Solid Brass Trim: Forged brass body and metal levers provide a premium feel and long-term durability in daily use.

The trim set is intended for concealed rough-in valves installed inside the wall, which keeps the bathroom tidy and easy to clean. It is an excellent choice for modern master bathrooms where a wall-mounted tub filler or a shower system is fed from the same valve position.

Because the temperature and volume are controlled independently, the mixer is also suitable for care homes and family bathrooms where consistent, safe water temperature is a priority. Matching INOVI shower heads, hoses, and tub spouts complete the installation.

The trim kit is shipped in a protective box with the faceplate, levers, diverter knob, and mounting screws separated by foam. Installation instructions for standard rough-in valves are included in several languages.

Each thermostat element is factory calibrated and tested for temperature accuracy before assembly. We offer a five-year warranty and technical support for installation and spare parts.
