Designing a sustainable bathroom: a guide to saving water and energy
Saving water in the bathroom has definitely become a key focus for both industry professionals and end consumers alike. A precious resource to be protected, water should never be wasted. It is an essential source of well-being and hygiene that should be used responsibly to optimize consumption and conserve resources. Advancements in research and technology have revolutionized industry standards, challenging long-held assumptions and truths. Today, growing awareness of the importance of these aspects plays a significant role in the choice of systems, fixtures and accessories for our home, particularly in the bathroom. The goal is to consume less and save more without sacrificing functionality or aesthetics.
Hydroprogressive mixer: water and energy savings in a single gesture
One of the most advanced solutions in faucet technology is undoubtedly the hydroprogressive mixer, exemplified by Giotto from CEA Design. CEA Design faucets are renowned for their refined aesthetics and the use of stainless steel, a sustainable and hygienic material. However, it is actually the innovative hidden technology that truly sets them apart. A solution that offers multiple advantages, not only for the end user but also for the environment. First and foremost, with a single, effortless gesture—the simple rotation of a knob—the user can switch from cold to mixed water and then to hot water while also controlling the flow delivered. Once the maximum flow rate is reached, it remains steady and consistent. Another key feature for conserving water is the aerators with flow restrictors integrated into the mixers. In addition to reducing water consumption, they also guarantee energy savings: by defaulting to cold water upon opening, they prevent unnecessary operation of the boiler or water heater.
Limiting energy consumption with eco-sensitive mixers
Savings are further optimized with eco-sensitive mixers, such as Via Manzoni by Gessi. This solution starts with the idea of delivering hot water only when truly needed. When the faucet lever is in the middle position, it dispenses only cold water, preventing the automatic activation of the boiler and thereby reducing energy consumption. In contrast, standard faucets trigger water heaters and boilers as soon as the lever is set to the middle position. Compared to hydroprogressive mixers, these models feature a dual-action cartridge, which allows users to control not only the water temperature but also the flow rate. Aerators with flow restrictors also play a crucial role in reducing water consumption by enriching the water flow with air for a comfortable jet. This achieves the same result, if not better, than traditional technology, with water savings. The most environmentally advanced faucets today can reduce water consumption to as little as 3 or 4 liters per minute.
Eco technologies for the perfect relaxing shower experience
Energy conservation took a significant step forward with the introduction of thermostatic mixers, a technology that has steadily evolved over time. These mixers operate on the principle that once the desired temperature is set, the thermostat keeps it constant throughout the entire shower. This eliminates the need for unnecessary adjustments that often lead to water waste while trying to find the ideal temperature. It also prevents fluctuations that put a strain on the boiler as it works to stabilize the temperature. Some more advanced models are equipped with an Eco button, which can further reduce water flow by up to 50% in some cases, without compromising the showering experience. An example of this is Grohtherm SmartControl by Grohe, an innovative shower control system that allows for effortless adjustment of both water intensity and temperature. It also enables users to select their preferred spray pattern and switch between the showerhead, hand shower and bathtub faucet. The spray intensity can be easily increased or decreased by simply turning the ergonomic GROHE ProGrip handle. Intelligent management allows users to “pause” the water flow and to save their preferred settings, ensuring the same personalized experience every time they shower.
The comfort of a shower thermostat combined with water and energy savings
The Ecostat shower thermostats by Hansgrohe feature advanced technology designed to optimize water and energy consumption, available for both outdoor and recessed installations. Elegance, functionality, refined geometries and minimal design combined with active regulation of water consumption that reduces temperature fluctuations and subsequent energy use. To this is added an extra safety feature. A temperature limiter that always ensures a safe and pleasurable shower experience. This function prevents excessively hot water from flowing out of the shower head. Protection against scalding is a great safety benefit, especially for children or people with limited mobility.
The elegance and comfort of a water-efficient shower head
Flow restrictors play an increasingly important role in the world of hand showers and showerheads, which now also incorporate innovative eco-friendly features that contribute to water savings. Zucchetti showerheads with Water Saving Technology offer a relaxing and refreshing shower experience, maintaining a flow rate of 9 liters per minute or less. Thanks to the air being drawn in by the shower body, water and air mix to create fuller, lighter and softer droplets. This effect enhances the quality of the water jet while significantly reducing water consumption.
Intelligent sanitary flush systems
Saving water goes beyond faucets and shower systems, extending to all technologies present in the bathroom. In particular, toilet cleaning and, consequently, the choice of flushing cisterns and their adjustment systems. Geberit has long been a leading brand in the industry, recognized for its attention to the aesthetics of these elements and their ability to integrate into bathroom decor with stylish finishes and details, as well as for its use of advanced technology. Always committed to sustainability, the Swiss company offers dual-flush control plates, which allow users to control the precise amount of water needed. Full flush options include 4, 4.5, 6, and 7.5 liters, while reduced flush volumes range from 2 to 4 liters. Geberit also offers a solution with Key-Stop, enabling users to stop the water flow at any time. This promotes mindful flushing that reduces unnecessary water waste.
