All tapware must be installed by a licensed plumber in accordance with AS/NZS 3500 and the brand's installation guide. Every product is WaterMark certified for use in Australia. Check the mounting type, hole size and spout reach against your basin or bath before rough-in, and confirm water pressure is within the brand's stated range (most mixers 150–500 kPa). Wall mixers and diverters are sold as a trim kit plus a separate in-wall body — order both. Keep the packaging until the installation is signed off.
