3 Features Included In This Product Explained



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

Stainless Steel Material

Stainless Steel Material

Stainless Steel is an iron alloy with anti-rust and anti-corrosive properties, unlike iron. It contains a minimum of 10.5% of chromium and less than 1.2% of carbon and other metal alloys. Its corrosion resistance and mechanical properties can be improved by adding nickel, molybdenum, titanium, niobium, or manganese. This robust, hygienic, hard-wearing base material is popular in the construction of steel products.

WRAS Approved Product
