Summary
Roca A505909803 Loft-T Thermostatic Cartridge for Shower and Bath/Shower Mixers
The Roca A505909803 Loft-T thermostatic cartridge for the Roca Loft shower and bath/shower mixers listed below. This is an internal temperature-control component, not a complete mixer valve.
The cartridge regulates the mixed water temperature inside the mixer. It serves a different function from the on/off headwork or bath/shower diverter, so identifying which control needs attention is important before ordering.
