A detailed studio close-up of the Aqualuso Opus Thermostatic Shower Mixer Valve, showing the inlet side of the valve assembly against a clean white background. This image clearly displays the 1/2” BSP threaded inlet connections used for hot and cold water supply, along with the additional inlet used to feed a steam generator where applicable. A high-resolution studio photograph of the Aqualuso Opus Thermostatic Shower Mixer Valve, shown fully assembled with all three chrome control dials installed, positioned horizontally against a clean white background. The image presents the valve as it would appear once fitted behind a shower cabin control panel, making it ideal for homeowners identifying a like-for-like replacement part. The valve consists of three evenly spaced cylindrical control sections connected by a solid metal manifold pipe. Each control is mounted on a circular chrome backplate, giving the valve a clean, symmetrical appearance. The left-hand control represents the selector mechanism used to direct water to the installed shower functions. The central control operates the flow and on/off function, while the right-hand control houses the thermostatic cartridge responsible for regulating and maintaining a stable water temperature. Below the control assembly, the chrome-plated valve body transitions into a textured metal housing where the threaded connection ports are visible. These 1/2” BSP threaded connections are designed for compatibility with Aqualuso Opus shower cabins and steam showers, allowing the valve to be replaced without modifying existing pipework. The image clearly shows the compact layout and fixed spacing between controls, confirming the 100mm centre-to-centre measurements used across the Opus range. Branding elements are visible within the image, including the Aqualusso logo in the lower corner and the Opus mark in the upper corner, reinforcing that this valve is part of the Opus system. This visual helps customers confidently identify the correct replacement mixer valve when their existing Aqualuso Opus shower valve has failed, seized, or no longer operates correctly.

The image highlights multiple 1/2” BSP threaded outlet ports extending from the chrome-plated brass housing, designed to distribute water to different shower functions within a shower cabin or steam shower. The polished chrome exterior contrasts with the visible brass threading inside each outlet, demonstrating the valve’s robust construction and suitability as a replacement part for Aqualuso Opus shower systems. The exposed control spindle at the top of the valve section indicates where the selector dial is fitted, allowing the user to direct water flow to the desired shower function.

Description

Aqualusso Thermostatic Shower Mixer Valve – Replacement OEM Part

The Aqualusso Thermostatic Shower Mixer Valve is a high-quality replacement valve designed specifically for Aqualusso Opus and Alto shower cabins and steam showers. It is most commonly purchased by homeowners whose original mixer valve has failed, seized, started leaking, or no longer regulates temperature correctly, and who want to restore their existing shower cabin rather than replace the entire unit.

This valve features a three-dial control layout, consistent across all variants. The bottom dial controls water temperature using a thermostatic cartridge to maintain a stable and safe temperature. The middle dial controls water flow and on/off operation. The top dial acts as a selector, allowing the user to switch between the shower functions installed in their cabin.

To suit different shower cabin layouts, this product is available in three-output, four-output, or five-output versions, all selectable from the product options above. This allows you to choose the correct configuration to match your existing shower without modifying pipework or internal fittings. Where fitted, steam generators are supplied via a separate steam inlet and are not counted as an output.

All variants are manufactured with 1/2” BSP threaded connections throughout, including hot water inlet, cold water inlet, steam inlet, and all outlet ports. This makes the valve suitable for straightforward replacement in most Opus shower cabins.

If your existing shower cabin uses push-fit hose connections, optional screw-on push-fit adapters are available. These adapters simply thread onto the valve body and allow your existing hoses to be secured using jubilee clips, avoiding the need to replace hoses or pipework. When selected, the appropriate number of adapters is supplied to match the chosen output configuration.

If your shower cabin does not use a steam generator — such as standard shower cabins, hydro massage showers, or open-top models — the steam inlet can be safely sealed using a blanking cap. A suitable brass blanking nut can be found here:

This valve is manufactured to match original Opus specifications, making it ideal for direct OEM replacement without altering the shower control panel.
