Significantly reducing water consumption while still delivering a satisfying shower experience, the Grohe Everstream is the latest addition to Grohe’s sustainable bathroom products. The cutting-edge water-circulating process curtails water usage by up to 75 per cent and energy by up to 66 per cent (for a 10-minute shower). How it works: Starting with fresh water, the integrated mechanism is manually switched after sudsing up and shampooing to pump the grey water collected in the drain through a circuit that hygienically treats it (while also maintaining its temperature) and recycles it through the system. Once the shower is complete, it auto-cleans for the next user.

A far cry from its bulky predecessors, the Kohler Loope waterless toilet has a minimalist design that doesn’t compromise on comfort. Made from recycled polyethylene, the container-based fixture was developed by Kohler’s in-house incubator, Innovation for Good, to address the safe sanitation needs of densely populated urban environments where access to clean water is not always guaranteed. Functional without water, electricity or a sewer connection, the modular loo has separate and easy-to-access (and empty) waste compartments and can accommodate a family of four with twice-weekly servicing.

Santa Monica–based studio Minarc designed the RUBBiSH ReFlow sink to help minimize daily water wastage and promote conscious consumption. Made from crisp white Corian and lined with a recycled rubber mat, the elongated sink recycles and repurposes water from daily rituals like face washing and toothbrushing to be used for toilet flushing. A gentle slope in the basin drains every drop directly into the tank, creating an “automatic, continuous and passive conservation of water.”
