It is recommended to buy a shower head with a water flow reducer, as well as a tap with a built-in aerator because such a head sucks in three litres of air for one litre of water, which creates massaging water jets and enables easy rinsing. Using a standard shower tap, 15–20 litres of water can flow out per minute, while an efficient shower tap may only use 8 litres per minute.

Water losses occur while the user adjusts the desired temperature; therefore, when purchasing a new water tap, it is recommended to choose a tap with a thermostat that allows you to set and maintain the desired water temperature throughout the wash.

If possible, select and buy plumbing equipment with easy-care surfaces. For instance, it is advisable to select a shower head with silicone nozzles, which are easier to clean.
