A shower timer is a simple but nifty device designed to help you keep your shower time to four minutes, using less energy and water as a result.
The shower timer fits easily onto your tiles or glass screen next to your shower with a suction cup. It acts as a handy reminder to keep your shower time to four minutes. According to the Energy Saving Trust, cutting just one minute from your shower time could save £15 in energy bills and the same in water bills for metered customers.
