The core principles of a sustainable bathroom emphasise a balance between practicality, simplicity, responsible production and conservation of the environment. Bathrooms that use natural products and items that prioritise energy and water efficiency, such as eco bathtubs or showers can foster a functional and cost-effective space. By using responsibly sourced options and ensuring that sustainability remains an integral component of the design agenda, a reduction in the carbon footprint of a bathroom renovation or build can be achieved.
