4 Features Included In This Product Explained



One outlet in a shower system means that hot and cold water flows from a single opening.

Thermostatic Control

Thermostatic Control

Thermostatic shower control works behind the scenes to achieve or maintain water temperature output from a showerhead. With the built-in safety feature, the shower provides a consistent water temperature.

Ceramic Disc Cartridge

Ceramic Disc Cartridge

It has two ceramic discs, one fixed in place and the other moveable with the tap or valve handle. It is the most common technology used in modern tapware as it offers unmatched advantages such as no leaks and drips and saves on water and money.

Medium Water Pressure

Medium Water Pressure

Water systems operating at a pressure between 0.5 and 0.9 bar are considered medium pressure. Products usually come labelled if they are suitable for use in medium pressure.
