Discover all GSI 's Dual Glaze+ toilet models. Dualglaze+ is the special treatment that GSI applies to coloured toilets with a Swirlflush® flushing system. GSI has combined hygiene and elegance in its Dualglaze range, giving sanitaryware an original and distinctive touch. Dualglaze technology combines gloss and matt glazes in a range of products aimed at customers with an eye for detail and for innovation. Where parts come into contact with water, the purity of the matt finish meets our Extraglaze® Antibacterial enamel, designed to prevent unhygienic lime deposits, a frequent phenomenon due to the porous nature of ceramic products having a single matt finish. GSI's Dual Glaze+ was honoured by the jury of the Plus X Award as ‘Best Product of the Year 2022’.
