Description
Aqualusso Thermostatic Cartridge – Replacement Vernet Wax Sensor (SP182)
The Aqualusso Thermostatic Cartridge is a high-quality OEM replacement cartridge designed for use in Aqualusso three-dial thermostatic shower mixer valves. It is the core temperature-regulating component found inside Aqualusso steam showers, shower cabins, and steam shower baths, and is most commonly replaced when temperature control becomes unreliable.
If your Aqualusso shower is running lukewarm, excessively hot, fluctuating in temperature, or the temperature control has become stiff or difficult to turn, this is a strong indication that the thermostatic cartridge has failed and requires replacement. Over time, limescale and wear can cause the internal wax sensor to degrade, preventing accurate temperature regulation.
This replacement cartridge is a branded Vernet wax sensor cartridge, widely regarded as more reliable and efficient than standard or unbranded thermostatic cartridges. The Vernet nylon sensor reacts precisely to temperature changes, ensuring safer and more consistent water temperatures once installed.
The cartridge is compatible with all Aqualusso steam showers and shower cabins manufactured since 2007, including both Aqualusso Alto and Aqualusso Opus ranges. It is also suitable for models now sold exclusively through Victorian Plumbing. This part is supplied as Aqualusso part number SP182.
To ensure maximum compatibility, the cartridge features both a threaded fixing and a grub screw design. This allows it to fit the different thermostatic valve assemblies Aqualusso have used across their three-dial mixer valves over the years, making it a straightforward like-for-like replacement.
Depending on production batch, the external body of the cartridge may be supplied in either brass or chrome-finished steel. Both versions use the same high-quality Vernet internal sensor and offer identical performance and compatibility. In many cases, this replacement cartridge is an upgrade on the original component fitted to the shower.
Replacing the thermostatic cartridge is often the most cost-effective way to restore proper temperature control to your Aqualusso steam shower or shower cabin, without the need to replace the entire mixer valve or shower unit.
