The hose is classed as "high flow", which means it has a large bore (wider diameter) hole to allow more water through the hose, this will improve the performance of low-pressure water systems (a water tank in the loft). The performance of the shower is improved because the hose minimises the friction and maximises the flow of water in order to deliver a powerful shower.
