- Electric showers use between 3 and 10 litres per minute. This can vary slightly depending on the kW rating, the ambient temperature of the cold water entering the shower and the showering temperature selected.
- Mixer showers generally use between 5 to 30 litres per minute, depending on the available water pressure. Flow restrictors supplied with most mixer showers will, if fitted, provide economical flow from the shower on high-pressure water supplies.
- Power showers consisting of a mixer and boost pump, will use between 10 and 16 litres per minute.
