Production

Turning raw materials into your dream design

It all starts with your idea, and it all ends with a solution that makes this idea a reality. Before one can become the other, there are various manufacturing processes to go through. We have over 70 years’ experience making bathroom products – here’s how we do it.

Raw manufacture
Our products take shape as a raw product. We place a titanium alloy steel sheet in our deep-drawing press, which deep-draws the steel up to 45 centimetres thick at 630 tons of pressure. This gives the steel tub its interior shape. We then cut the metal, machine the rims, and press and stamp the holes for the drain and overflow. Our experts inspect each individual tub with their practised eye before the pre-treatment facility cleans and scours the material, making the raw product ready for enamelling.

Enamelling

Enamel is what gives your steel bathtub its shiny, scratch-free and acid-resistant surface. It is made entirely from natural raw materials: the necessary substances – borax, feldspar, quartz, soda, aluminium oxide and other metal oxides – are melted together at high temperatures to form enamel frits. The enamel frit is then mixed and ground with water and clay. This results in enamel slip, which we spray wet onto the steel tubs and bake in a continuous furnace at a temperature of 850 degrees. During this process the ground enamel is combined with the steel to form a composite material. A second enamel layer is then applied as part of the same process, which gives the tubs their colour and unique surface properties.

Inspection
We make no compromises on quality. For this reason, we carry out a double final inspection to ensure that no defective products leave our factory. If the finished steel bathtub passes this strict examination from our quality controllers, it is securely packaged and, if required, prepared for immediate delivery to the bathroom stockist.
