For a powerful showering experience in a low-pressure area, the Pression 1 Function Shower Set in matt black works to boost the pressure of your shower, providing a more luxurious showering experience. With a Flexi-Fix riser rail for adjustability and simple installation. Pressure Boost Precision works in a similar way to a nozzle on a garden hose. Without a nozzle, water flows freely but with little pressure. Add a nozzle, and the water pressure increases significantly. Our pressure boost handsets use similar technology in the bathroom to help you love your shower again. Low pressure? No problem! Precision.
