Xellanz Twenty Eco thermostatic cartridge for rain showers

The Xellanz Twenty Eco thermostatic cartridge for rain showers is the replacement heart of a surface-mounted thermostatic rain shower from the Twenty range. If the water temperature fluctuates in the shower or the water stays lukewarm, the thermostatic element is usually worn. This spare part restores full performance without replacing the entire rain shower.

Stable temperature: a new thermostatic element maintains the water at the set temperature, even when a tap is opened elsewhere in the house.

For surface-mounted rain showers: this cartridge is designed for surface-mounted thermostatic rain showers — systems that are visibly mounted on the wall.

Twenty Eco version: the part belongs to the Twenty Eco range, ensuring a perfect fit and correct connection.

Cost-effective repair: replacing only the cartridge costs a fraction of a new thermostatic rain shower.

Five-year warranty: this Xellanz thermostatic cartridge comes with a five-year warranty.
